Before you start
- Check the paving material, base construction, drainage and working temperature before choosing the application method.
- Make sure the paving is firm, stable and fully supported. PremJoint will not stabilise loose paving.
- Rake all joints to their full depth, removing bedding mortar, debris and loose material. Joints should be 3–20mm wide and at least 20mm deep.
- Remove dried mortar and cleaning-chemical residues from the paving. Take particular care with acid-based cleaners, which can damage or discolour some paving and PremJoint.
Wet Application: permeable bed
- Use only where the bedding and sub-base are free draining and application water can drain through into the ground.
- Hose down the paving thoroughly before and during application. This saturates the paving, helps prevent oils entering the surface, assists joint penetration and washes away excess material.
- Pour PremJoint along the joints and brush it in until the full width and depth are filled without voids.
- Keep the finished joint slightly below the paving surface. The paving should remain the wear surface.
- Allow the joint to drain and air cure. In good conditions, allow approximately 24–48 hours before foot traffic.
Dry Application: impermeable bed or poor drainage
- Use the Dry Application method where the bedding is impermeable, drainage is poor, stronger driveway bedding is used, or temperatures are approaching or below 3°C.
- Once the paving is firmly secured and set, lightly mist the paving surface without wetting the joints.
- Pour PremJoint along the joints and brush it in. Use a pointing trowel and jointing iron to compress the material fully into the joint.
- Finish the joint slightly below the paving surface and remove excess material from the paving.
- Allow the joint to air cure fully before opening to traffic or positioning a metal recess tray.
Metal recess trays
Fix paving into the tray with a suitable epoxy mortar such as UltraScape Resi-Bed. Use the Dry Application method for PremJoint and allow the jointing to fully cure before locating the tray into position.
About the product
UltraScape PremJoint Fine 15KG is a decorative, fine-grade brush-in paving jointing compound and permeable paving grout for patios, granite, porcelain and premium natural stone.
Choose from Cosmic Black, Storm Grey, Pebble Grey and Natural Cashmere. Once cured, the joint is permeable, with Wet or Dry Application selected according to the bedding and drainage conditions.
For 3–20mm joints with a minimum 20mm depth. Allow approximately 24–48 hours before foot traffic in good drying conditions. Coverage is approximate and depends on your slab size, joint width, joint depth and total area, so use our quantity calculator or contact our family-run team before ordering.
UltraScape PremJoint Fine Brush-in Jointing Compound
UltraScape PremJoint Fine is a decorative, fine-grade brush-in paving jointing compound and permeable paving grout for granite, porcelain and other premium natural stone. Once cured, it creates permeable jointing and is available in four colours: Cosmic Black, Storm Grey, Pebble Grey and Natural Cashmere.
PremJoint is a practical jointing compound for patios, walkways and suitable light, non-trafficable commercial paving. It can be used with permeable or impermeable bedding, but the application method must match the base: use the Wet Application method where water can drain freely through the bedding, and the Dry Application method where the bed is impermeable or drying conditions are poor.
We’re a small, family-run business, so we know that a paving jointing compound is only as good as the preparation beneath it. PremJoint will not stabilise loose paving or correct a poorly designed base. Before ordering, check the paving material, bed construction, joint size, drainage and the conditions in which you will be working.

Choose the application method for the bedding
PremJoint is air cured, so moisture needs to leave the joint before it can harden properly. The correct application method depends on whether the bedding below the paving is permeable or impermeable.
Wet Application for a permeable bed
Use the Wet Application method where paving is fixed on a permeable, free-draining bedding material. This is commonly used for patios and walkways carrying normal domestic foot traffic. The bedding should support the paving in a continuous solid bed while still allowing water to drain into the ground.
Permeable examples include a suitable permeable bound bedding mortar, compacted sand, or compacted Type 1 stone or combinations of these. Where unbound bedding is used, the paving must be stable and edged on all sides with fixed kerbs or edging stones to prevent movement.
For a bound domestic foot-traffic bed, the supplied guidance gives no more than approximately 6 or 7 parts clean sharp sand to 1 part Portland cement. Add enough water for the bedding mix to hold together when gently squeezed in a gloved hand. Higher cement ratios reduce permeability and can extend PremJoint drying time. Dot-and-dab fixing should not be used, and the sub-base should be properly compacted before the bedding is installed.
Before applying PremJoint, hose down the fixed paving thoroughly and continue using plenty of water during application. This helps saturate the paving, reduce the risk of oils entering the paving, ease brushing, encourage deep joint penetration and wash away excess material. The water must drain through the joints and bedding. PremJoint will remain soft until moisture has left the full depth of the joint.
Dry Application for an impermeable bed
Use the Dry Application method where the bedding mortar is impermeable and will not allow application water to drain away. It is also the preferred method for domestic driveways with stronger, higher-cement bedding, existing substrates with poor drainage or drying conditions, and when temperatures are approaching or below 3°C.
Once the paving is firmly secured and set, lightly mist the paving surface without wetting the joints. This helps reduce staining. Open the PremJoint tub, pour the material along the joint and brush it in. Because there is no water to wash the material into the joint, use a pointing trowel and jointing iron to compress it fully into place.
Joint preparation and finishing
All joints should be between 3mm and 20mm wide and at least 20mm deep. A deeper joint can increase strength but may extend drying time. Rake all joints to their full depth so they are free from bedding mortar, debris and other material that could prevent PremJoint contacting the joint walls.
PremJoint must fill the full width and depth without voids. Voids create permanent weak points. With natural stone that has sloping edges, a channel can be formed in the bedding below the V-shaped joint using the end of a pointing trowel, helping the jointing key into place.
Brush or tool the fresh joint slightly below the paving surface. The paving, not the jointing, should remain the wear surface. A grouting tool can be run over the face before curing to firm and smooth the finish.
Curing and opening to foot traffic
PremJoint is air cured. In good drying conditions around 20°C and 65% relative humidity, and where water is free draining, it will firm up in approximately 24–48 hours, which is generally sufficient for foot traffic. It will continue hardening over the following 28 days.
Temperature, residual moisture, poor drainage, porous paving and freezing conditions all affect the curing rate. Wet-applied joints may take longer if water remains in the base or joint. Once moisture has dried away, curing can resume. Do not treat the 24–48-hour period as a guarantee where site conditions are cooler, damp or poorly draining.
Cleaning and aftercare
Before jointing
Remove all dried mortar from the paving before applying PremJoint. Wash away mortar residues and cleaning chemicals completely. Acid-based cleaners can affect both the paving and the jointing, and can cause orange or brown discolouration where iron compounds are present. Limestone, marble and other paving can also be damaged by acid cleaners. Test a discreet area and follow the paving supplier’s advice before using any cleaning product.
After the joint has cured
Only clean PremJoint after it has fully hardened. For surface dirt and organic debris, use clean soapy water and a gentle domestic pressure-washer spray at the lowest pressure, approximately 100–130 bar. Hold the nozzle at least 30cm from the surface and keep the fan of water at roughly a 45-degree angle to the joint. A soft-bristle sweeping brush can also be used.
Do not use motorised or mechanical sweepers, as they are too abrasive for the jointing. Water-based biocides can be used for moss and lichen, but test a small area first to check compatibility.
Important limitations and suitability checks
- PremJoint is not intended to stabilise loose or moving paving.
- All paving must be firm, stable and supported by a suitable base before jointing begins.
- Porous paving may hold water and delay curing, and some porous materials may need sealing before jointing because they are more sensitive to staining.
- For porcelain, check the process with the paving supplier first. A separate preparation process involving slurry primer may be required.
- For metal recess trays, paving should be fixed inside the tray with an epoxy mortar such as UltraScape Resi-Bed. Apply PremJoint using the Dry Application method only once the paving and jointing are fully cured, before locating the tray into position.
- Edge paving, preformed gullies, grids and access-cover frames should be firmly fixed and stabilised in bedding mortar so they cannot move.
- Natural aggregates can vary slightly in colour. Trial a small section if you need to confirm the finished colour with a particular paving material.
PremJoint questions we’re asked
We’re a small, knowledgeable team, and these are the practical questions that matter most when choosing a brush-in paving jointing compound.
What is UltraScape PremJoint Fine?
PremJoint Fine is a decorative, fine-grade brush-in jointing compound for suitable granite, porcelain and premium natural stone paving. Once cured, the joint is permeable and allows air and rainwater to pass through.
What is PremJoint jointing compound used for?
PremJoint is used as a paving jointing compound for suitable patios, walkways, granite paving, porcelain paving and other premium natural stone. Choose the Wet or Dry Application method according to the bedding and drainage conditions.
Is PremJoint permeable?
Yes. Once fully cured, PremJoint provides permeable jointing. The bedding and base still need to be designed so water can drain where the Wet Application method is being used.
Can PremJoint be used on an impermeable bed?
Yes. Use the Dry Application method on an impermeable bedding mortar or another poorly draining base. Do not use the Wet Application method where its water cannot drain away.
Can PremJoint be used on a permeable bed?
Yes. Use the Wet Application method on a suitable free-draining bed. The water used during application must drain through the joints and bedding before PremJoint can cure properly.
What is the best jointing compound for paving?
There is no single best paving jointing compound for every installation. The right choice depends on the paving material, joint size, bedding, drainage, loading and weather conditions. PremJoint is a permeable brush-in paving jointing compound where its Wet or Dry Application method suits the construction.
What is the best jointing compound for patios?
For a patio, choose a jointing compound that suits the paving and the bed beneath it. PremJoint is suitable for appropriate domestic patio and walkway applications, with Wet Application for free-draining beds and Dry Application for impermeable or poorly draining beds.
Can PremJoint be used on a domestic driveway?
It can be used on suitable domestic driveway paving where the paving is stable, the joints are correctly prepared and the Dry Application method is selected for an impermeable or higher-strength bedding construction. It is not a substitute for a properly designed driveway base.
How do you apply UltraScape PremJoint?
First prepare stable paving and clean, full-depth joints. Use the Wet Application method with plenty of water on a permeable bed, or the Dry Application method with a light mist on the paving surface and no water in the joints where the bed is impermeable or drainage is poor. In both cases, fill the joint fully without voids and finish it slightly below the paving surface.
What joint width is suitable for PremJoint?
Joints should be a minimum of 3mm and a maximum of 20mm wide, with a minimum depth of 20mm.
How long before you can walk on PremJoint?
In good drying conditions around 20°C and 65% relative humidity, and where water drains freely, allow approximately 24–48 hours before normal foot traffic. Cooler, wetter or poorly draining conditions can extend this time.
How long does PremJoint take to cure?
PremJoint will usually firm up in approximately 24–48 hours in good drying conditions and will continue hardening for up to 28 days. Residual moisture, temperature and drainage affect the actual cure time.
Can PremJoint be used in the rain?
PremJoint can be used in changing weather when the correct application method and drainage conditions are in place. Wet Application water must be able to drain away, and lingering moisture will delay curing.
Can PremJoint be used below 3°C?
Where temperatures are approaching or below 3°C, the Dry Application method is preferred because water in a Wet Application joint may freeze and expand before it has drained, weakening the uncured joint.
Is PremJoint frost resistant?
PremJoint is resistant to freeze/thaw conditions once correctly cured. Freezing conditions during application can damage an uncured Wet Application joint if water has not drained away.
Can PremJoint be used with porcelain paving?
Check with the porcelain paving supplier before starting. Porcelain may require a separate preparation process, including slurry primer, and some surfaces are more sensitive to staining.
Can PremJoint be used with natural stone?
Yes, it is suitable for appropriate granite and other premium natural stone paving, subject to the stone’s porosity, staining sensitivity, base construction and the paving supplier’s guidance.
Can PremJoint be used with granite paving?
Yes. Granite paving is one of the stated suitable applications, provided the paving is stable, the joint is prepared correctly and the chosen application method matches the bedding and drainage conditions.
What colours does PremJoint Fine come in?
The four colours are Cosmic Black, Storm Grey, Pebble Grey and Natural Cashmere. Natural aggregate variation means a small trial area is sensible where colour matching matters.
How much does a 15KG tub cover?
Coverage depends on the paving size, joint width and joint depth. The verified product information gives approximately 8–9.5m² based on 450mm × 450mm paving, 25mm depth and an 8mm joint gap.
How much PremJoint do I need?
Use the quantity calculator on this page with the paving length and width, joint width and joint depth. As a guide, the verified product information gives approximately 8–9.5m² per 15KG tub under the stated 450mm × 450mm, 25mm-depth and 8mm-gap example. Allow for changing joint dimensions and site wastage.
Can leftover PremJoint be reused?
Yes. Leftover material can be re-used, provided it remains suitable for use and is kept in appropriate condition. Avoid introducing moisture or contamination into unused material.
Can PremJoint stabilise loose paving?
No. PremJoint is a jointing compound, not a method for stabilising loose paving. The paving must be firm and stable on a suitable base before jointing begins.
Can PremJoint be pressure washed?
Only after it has fully hardened. Use clean soapy water and a domestic pressure washer at the lowest pressure, approximately 100–130 bar, holding the nozzle at least 30cm away and directing the fan at roughly 45 degrees. Do not use motorised sweepers.
Can acid cleaner be used before PremJoint?
Take extreme care. Acid-based cleaners can damage or discolour some paving and PremJoint. Remove all residues, test a discreet area first and follow the paving supplier’s guidance.
Can PremJoint be used in a metal recess tray?
Yes, where the paving is fixed into the tray with a suitable epoxy mortar such as UltraScape Resi-Bed. Use the Dry Application method and allow the jointing to fully cure before locating the tray into position.

Check with the porcelain paving supplier before starting. Porcelain may require a separate preparation process, including slurry primer, and some surfaces are more sensitive to staining.
Can PremJoint be used with natural stone?
Yes, it is suitable for appropriate granite and other premium natural stone paving, subject to the stone’s porosity, staining sensitivity, base construction and the paving supplier’s guidance.
Can PremJoint be used with granite paving?
Yes. Granite paving is one of the stated suitable applications, provided the paving is stable, the joint is prepared correctly and the chosen application method matches the bedding and drainage conditions.
What colours does PremJoint Fine come in?
The four colours are Cosmic Black, Storm Grey, Pebble Grey and Natural Cashmere. Natural aggregate variation means a small trial area is sensible where colour matching matters.
How much does a 15KG tub cover?
Coverage depends on the paving size, joint width and joint depth. The verified product information gives approximately 8–9.5m² based on 450mm × 450mm paving, 25mm depth and an 8mm joint gap.
How much PremJoint do I need?
Use the quantity calculator on this page with the paving length and width, joint width and joint depth. As a guide, the verified product information gives approximately 8–9.5m² per 15KG tub under the stated 450mm × 450mm, 25mm-depth and 8mm-gap example. Allow for changing joint dimensions and site wastage.
Can leftover PremJoint be reused?
Yes. Leftover material can be re-used, provided it remains suitable for use and is kept in appropriate condition. Avoid introducing moisture or contamination into unused material.
Can PremJoint stabilise loose paving?
No. PremJoint is a jointing compound, not a method for stabilising loose paving. The paving must be firm and stable on a suitable base before jointing begins.
Can PremJoint be pressure washed?
Only after it has fully hardened. Use clean soapy water and a domestic pressure washer at the lowest pressure, approximately 100–130 bar, holding the nozzle at least 30cm away and directing the fan at roughly 45 degrees. Do not use motorised sweepers.
Can acid cleaner be used before PremJoint?
Take extreme care. Acid-based cleaners can damage or discolour some paving and PremJoint. Remove all residues, test a discreet area first and follow the paving supplier’s guidance.
Can PremJoint be used in a metal recess tray?
Yes, where the paving is fixed into the tray with a suitable epoxy mortar such as UltraScape Resi-Bed. Use the Dry Application method and allow the jointing to fully cure before locating the tray into position.
Where can I buy UltraScape PremJoint?
You can buy UltraScape PremJoint Fine from The Paving Experts as a 15KG tub. If you are unsure how much you need or which application method suits your paving build-up, contact our family-run team before ordering.

Before you start
- Check the paving material, base construction, drainage and working temperature before choosing the application method.
- Make sure the paving is firm, stable and fully supported. PremJoint will not stabilise loose paving.
- Rake all joints to their full depth, removing bedding mortar, debris and loose material. Joints should be 3–20mm wide and at least 20mm deep.
- Remove dried mortar and cleaning-chemical residues from the paving. Take particular care with acid-based cleaners, which can damage or discolour some paving and PremJoint.
Wet Application: permeable bed
- Use only where the bedding and sub-base are free draining and application water can drain through into the ground.
- Hose down the paving thoroughly before and during application. This saturates the paving, helps prevent oils entering the surface, assists joint penetration and washes away excess material.
- Pour PremJoint along the joints and brush it in until the full width and depth are filled without voids.
- Keep the finished joint slightly below the paving surface. The paving should remain the wear surface.
- Allow the joint to drain and air cure. In good conditions, allow approximately 24–48 hours before foot traffic.
Dry Application: impermeable bed or poor drainage
- Use the Dry Application method where the bedding is impermeable, drainage is poor, stronger driveway bedding is used, or temperatures are approaching or below 3°C.
- Once the paving is firmly secured and set, lightly mist the paving surface without wetting the joints.
- Pour PremJoint along the joints and brush it in. Use a pointing trowel and jointing iron to compress the material fully into the joint.
- Finish the joint slightly below the paving surface and remove excess material from the paving.
- Allow the joint to air cure fully before opening to traffic or positioning a metal recess tray.
Metal recess trays
Fix paving into the tray with a suitable epoxy mortar such as UltraScape Resi-Bed. Use the Dry Application method for PremJoint and allow the jointing to fully cure before locating the tray into position.

UltraScape PremJoint Fine Brush-in Jointing Compound
UltraScape PremJoint Fine is a decorative, fine-grade brush-in paving jointing compound and permeable paving grout for granite, porcelain and other premium natural stone. Once cured, it creates permeable jointing and is available in four colours: Cosmic Black, Storm Grey, Pebble Grey and Natural Cashmere.
PremJoint is a practical jointing compound for patios, walkways and suitable light, non-trafficable commercial paving. It can be used with permeable or impermeable bedding, but the application method must match the base: use the Wet Application method where water can drain freely through the bedding, and the Dry Application method where the bed is impermeable or drying conditions are poor.
We’re a small, family-run business, so we know that a paving jointing compound is only as good as the preparation beneath it. PremJoint will not stabilise loose paving or correct a poorly designed base. Before ordering, check the paving material, bed construction, joint size, drainage and the conditions in which you will be working.
Why choose PremJoint Fine for patios and paving?
- Fine-grade brush-in paving jointing compound for decorative outdoor paving
- Suitable for granite paving, porcelain and other premium natural stone, subject to the correct preparation and paving-supplier guidance
- Four colours to coordinate with popular paving choices: Cosmic Black, Storm Grey, Pebble Grey and Natural Cashmere
- Permeable once cured, allowing air and rainwater to pass through the joint
- Suitable for joint widths from 3mm to 20mm
- Minimum recommended joint depth of 20mm
- Approximately 24–48 hours before foot traffic in good drying conditions
- Resistant to freeze/thaw conditions once correctly cured
- Enhanced workability and quick, straightforward application
- Leftover material can be re-used, helping reduce waste
- NBS Source registered for specification work
- Supplied in a 15KG tub
Choose the application method for the bedding
PremJoint is air cured, so moisture needs to leave the joint before it can harden properly. The correct application method depends on whether the bedding below the paving is permeable or impermeable.
Wet Application for a permeable bed
Use the Wet Application method where paving is fixed on a permeable, free-draining bedding material. This is commonly used for patios and walkways carrying normal domestic foot traffic. The bedding should support the paving in a continuous solid bed while still allowing water to drain into the ground.
Permeable examples include a suitable permeable bound bedding mortar, compacted sand, or compacted Type 1 stone or combinations of these. Where unbound bedding is used, the paving must be stable and edged on all sides with fixed kerbs or edging stones to prevent movement.
For a bound domestic foot-traffic bed, the supplied guidance gives no more than approximately 6 or 7 parts clean sharp sand to 1 part Portland cement. Add enough water for the bedding mix to hold together when gently squeezed in a gloved hand. Higher cement ratios reduce permeability and can extend PremJoint drying time. Dot-and-dab fixing should not be used, and the sub-base should be properly compacted before the bedding is installed.
Before applying PremJoint, hose down the fixed paving thoroughly and continue using plenty of water during application. This helps saturate the paving, reduce the risk of oils entering the paving, ease brushing, encourage deep joint penetration and wash away excess material. The water must drain through the joints and bedding. PremJoint will remain soft until moisture has left the full depth of the joint.
Dry Application for an impermeable bed
Use the Dry Application method where the bedding mortar is impermeable and will not allow application water to drain away. It is also the preferred method for domestic driveways with stronger, higher-cement bedding, existing substrates with poor drainage or drying conditions, and when temperatures are approaching or below 3°C.
Once the paving is firmly secured and set, lightly mist the paving surface without wetting the joints. This helps reduce staining. Open the PremJoint tub, pour the material along the joint and brush it in. Because there is no water to wash the material into the joint, use a pointing trowel and jointing iron to compress it fully into place.
Joint preparation and finishing
All joints should be between 3mm and 20mm wide and at least 20mm deep. A deeper joint can increase strength but may extend drying time. Rake all joints to their full depth so they are free from bedding mortar, debris and other material that could prevent PremJoint contacting the joint walls.
PremJoint must fill the full width and depth without voids. Voids create permanent weak points. With natural stone that has sloping edges, a channel can be formed in the bedding below the V-shaped joint using the end of a pointing trowel, helping the jointing key into place.
Brush or tool the fresh joint slightly below the paving surface. The paving, not the jointing, should remain the wear surface. A grouting tool can be run over the face before curing to firm and smooth the finish.
Curing and opening to foot traffic
PremJoint is air cured. In good drying conditions around 20°C and 65% relative humidity, and where water is free draining, it will firm up in approximately 24–48 hours, which is generally sufficient for foot traffic. It will continue hardening over the following 28 days.
Temperature, residual moisture, poor drainage, porous paving and freezing conditions all affect the curing rate. Wet-applied joints may take longer if water remains in the base or joint. Once moisture has dried away, curing can resume. Do not treat the 24–48-hour period as a guarantee where site conditions are cooler, damp or poorly draining.
Cleaning and aftercare
Before jointing
Remove all dried mortar from the paving before applying PremJoint. Wash away mortar residues and cleaning chemicals completely. Acid-based cleaners can affect both the paving and the jointing, and can cause orange or brown discolouration where iron compounds are present. Limestone, marble and other paving can also be damaged by acid cleaners. Test a discreet area and follow the paving supplier’s advice before using any cleaning product.
After the joint has cured
Only clean PremJoint after it has fully hardened. For surface dirt and organic debris, use clean soapy water and a gentle domestic pressure-washer spray at the lowest pressure, approximately 100–130 bar. Hold the nozzle at least 30cm from the surface and keep the fan of water at roughly a 45-degree angle to the joint. A soft-bristle sweeping brush can also be used.
Do not use motorised or mechanical sweepers, as they are too abrasive for the jointing. Water-based biocides can be used for moss and lichen, but test a small area first to check compatibility.
Important limitations and suitability checks
- PremJoint is not intended to stabilise loose or moving paving.
- All paving must be firm, stable and supported by a suitable base before jointing begins.
- Porous paving may hold water and delay curing, and some porous materials may need sealing before jointing because they are more sensitive to staining.
- For porcelain, check the process with the paving supplier first. A separate preparation process involving slurry primer may be required.
- For metal recess trays, paving should be fixed inside the tray with an epoxy mortar such as UltraScape Resi-Bed. Apply PremJoint using the Dry Application method only once the paving and jointing are fully cured, before locating the tray into position.
- Edge paving, preformed gullies, grids and access-cover frames should be firmly fixed and stabilised in bedding mortar so they cannot move.
- Natural aggregates can vary slightly in colour. Trial a small section if you need to confirm the finished colour with a particular paving material.
PremJoint questions we’re asked
We’re a small, knowledgeable team, and these are the practical questions that matter most when choosing a brush-in paving jointing compound.
What is UltraScape PremJoint Fine?
PremJoint Fine is a decorative, fine-grade brush-in jointing compound for suitable granite, porcelain and premium natural stone paving. Once cured, the joint is permeable and allows air and rainwater to pass through.
What is PremJoint jointing compound used for?
PremJoint is used as a paving jointing compound for suitable patios, walkways, granite paving, porcelain paving and other premium natural stone. Choose the Wet or Dry Application method according to the bedding and drainage conditions.
Is PremJoint permeable?
Yes. Once fully cured, PremJoint provides permeable jointing. The bedding and base still need to be designed so water can drain where the Wet Application method is being used.
Can PremJoint be used on an impermeable bed?
Yes. Use the Dry Application method on an impermeable bedding mortar or another poorly draining base. Do not use the Wet Application method where its water cannot drain away.
Can PremJoint be used on a permeable bed?
Yes. Use the Wet Application method on a suitable free-draining bed. The water used during application must drain through the joints and bedding before PremJoint can cure properly.
What is the best jointing compound for paving?
There is no single best paving jointing compound for every installation. The right choice depends on the paving material, joint size, bedding, drainage, loading and weather conditions. PremJoint is a permeable brush-in paving jointing compound where its Wet or Dry Application method suits the construction.
What is the best jointing compound for patios?
For a patio, choose a jointing compound that suits the paving and the bed beneath it. PremJoint is suitable for appropriate domestic patio and walkway applications, with Wet Application for free-draining beds and Dry Application for impermeable or poorly draining beds.
Can PremJoint be used on a domestic driveway?
It can be used on suitable domestic driveway paving where the paving is stable, the joints are correctly prepared and the Dry Application method is selected for an impermeable or higher-strength bedding construction. It is not a substitute for a properly designed driveway base.
How do you apply UltraScape PremJoint?
First prepare stable paving and clean, full-depth joints. Use the Wet Application method with plenty of water on a permeable bed, or the Dry Application method with a light mist on the paving surface and no water in the joints where the bed is impermeable or drainage is poor. In both cases, fill the joint fully without voids and finish it slightly below the paving surface.
What joint width is suitable for PremJoint?
Joints should be a minimum of 3mm and a maximum of 20mm wide, with a minimum depth of 20mm.
How long before you can walk on PremJoint?
In good drying conditions around 20°C and 65% relative humidity, and where water drains freely, allow approximately 24–48 hours before normal foot traffic. Cooler, wetter or poorly draining conditions can extend this time.
How long does PremJoint take to cure?
PremJoint will usually firm up in approximately 24–48 hours in good drying conditions and will continue hardening for up to 28 days. Residual moisture, temperature and drainage affect the actual cure time.
Can PremJoint be used in the rain?
PremJoint can be used in changing weather when the correct application method and drainage conditions are in place. Wet Application water must be able to drain away, and lingering moisture will delay curing.
Can PremJoint be used below 3°C?
Where temperatures are approaching or below 3°C, the Dry Application method is preferred because water in a Wet Application joint may freeze and expand before it has drained, weakening the uncured joint.
Is PremJoint frost resistant?
PremJoint is resistant to freeze/thaw conditions once correctly cured. Freezing conditions during application can damage an uncured Wet Application joint if water has not drained away.
Can PremJoint be used with porcelain paving?
Check with the porcelain paving supplier before starting. Porcelain may require a separate preparation process, including slurry primer, and some surfaces are more sensitive to staining.
Can PremJoint be used with natural stone?
Yes, it is suitable for appropriate granite and other premium natural stone paving, subject to the stone’s porosity, staining sensitivity, base construction and the paving supplier’s guidance.
Can PremJoint be used with granite paving?
Yes. Granite paving is one of the stated suitable applications, provided the paving is stable, the joint is prepared correctly and the chosen application method matches the bedding and drainage conditions.
What colours does PremJoint Fine come in?
The four colours are Cosmic Black, Storm Grey, Pebble Grey and Natural Cashmere. Natural aggregate variation means a small trial area is sensible where colour matching matters.
How much does a 15KG tub cover?
Coverage depends on the paving size, joint width and joint depth. The verified product information gives approximately 8–9.5m² based on 450mm × 450mm paving, 25mm depth and an 8mm joint gap.
How much PremJoint do I need?
Use the quantity calculator on this page with the paving length and width, joint width and joint depth. As a guide, the verified product information gives approximately 8–9.5m² per 15KG tub under the stated 450mm × 450mm, 25mm-depth and 8mm-gap example. Allow for changing joint dimensions and site wastage.
Can leftover PremJoint be reused?
Yes. Leftover material can be re-used, provided it remains suitable for use and is kept in appropriate condition. Avoid introducing moisture or contamination into unused material.
Can PremJoint stabilise loose paving?
No. PremJoint is a jointing compound, not a method for stabilising loose paving. The paving must be firm and stable on a suitable base before jointing begins.
Can PremJoint be pressure washed?
Only after it has fully hardened. Use clean soapy water and a domestic pressure washer at the lowest pressure, approximately 100–130 bar, holding the nozzle at least 30cm away and directing the fan at roughly 45 degrees. Do not use motorised sweepers.
Can acid cleaner be used before PremJoint?
Take extreme care. Acid-based cleaners can damage or discolour some paving and PremJoint. Remove all residues, test a discreet area first and follow the paving supplier’s guidance.
Can PremJoint be used in a metal recess tray?
Yes, where the paving is fixed into the tray with a suitable epoxy mortar such as UltraScape Resi-Bed. Use the Dry Application method and allow the jointing to fully cure before locating the tray into position.
