How do I mix & apply Flowpoint Smooth Paving Grout?
Follow these simple ten steps to use Flowpoint slurry grout to fill paving joints:- Firstly clean the paving slabs and joints so they are free from debris and any excess water
- Pre-soak the paving joints & surfaces with water to ensure they are damp – a light spray of water should be perfect
- Pour the Flowpoint powder into a bucket and add 4.25 litres of water
- Mix with a force action mixer for 3–5 minutes, until the consistency is smooth and free of clumps
- Before pouring the slurry mix, ensure that the area is still damp, apply the mixture immediately by carefully forcing Flowpoint into the joints using a rubber squeegee. Flowpoint can set within as little as 15 minutes (at temperatures of 20oC) so you will need to be quick, but careful
- Move the Flowpoint slurry across the patio surface to top-up joints where the mortar has sunk
- Use the rubber squeegee to remove as much of the paving grout from the surface of the slabs – still keep the surfaces constantly damp to prevent the grout from hardening
- Use a brush and plenty of water (or alternatively a sponge machine) to remove any grout that has hardened on the paving surfaces
- Once the mortar is dry (after about 30 minutes - depending on temperature), clean the surface of paving slabs thoroughly to remove any spots of mortar and prevent staining, you'll be looking for clean water running of the patio
- The pavers are ready to walk on after one hour and can receive car traffic after four hours

How long does Flowpoint Smooth Grout take to cure & set?
Flowpoint rapid-setting paving grout typically takes about 30 minutes to set and can be walked on within one hour under normal conditions. However, the full curing time depends on several factors, including temperature, humidity, and the specific formulation used. In general, at 20 degrees Flowpoint reaches its full strength within 24 to 48 hours, though it may continue to gain additional strength over several days. In colder (click link for our article on grouting in colder temperatures) or wetter conditions, curing may take longer, while warmer temperatures can accelerate the process (click the link for more info). Proper curing ensures durability and long-term performance, making it crucial to follow manufacturer guidelines for optimal results.
Will Flowpoint Smooth Grout Stain My Paving?
Flowpoint Paving Grout is designed to be stain-free and resistant to efflorescence—provided it’s applied correctly and in line with the manufacturer’s instructions.
Staining is not a fault of the product, but typically a result of installation errors. Common causes include:
- Skipping a paving primer like Ultrascape Pro-Prime
-
Not lightly misting the slabs with water during application
-
Over-watering the grout mix, or leaving water sitting on the surface or in the joints
These issues can lead to grout haze, surface staining, or uneven color patches—which can be very difficult to clean once set.
How to Avoid Staining with Flowpoint Smooth Paving Grout!
Keep your paving looking its best with these simple best practices:
1. Prime before you grout
Use a high-quality primer such as Ultrascape Pro-Prime to help the paving bond to the mortar bed and block any moisture or stains from migrating through.
2. Keep slabs misted
Throughout the grouting process, lightly mist your slabs using a garden hose with a rose head or a spray bottle. This prevents premature drying and surface residue.
3. Watch your water
Avoid adding too much water to the grout mix, and don’t let water collect on the surface or in the joints. Too much water can result in cracking, staining, and a patchy finish.
4. Use the right tools
Apply the grout with a neoprene squeegee to push the material deep into the joints while clearing excess from the slab surface.
✅ Flowpoint Smooth doesn’t cause staining when used correctly.
Following proper installation steps will ensure a clean, consistent finish—free from haze, residue, or discolouration.
What is the Shelf Life for Flowpoint?
Shelf life from date of manufacture printed on the bag, unopened in the above conditions, for sealed bags is 8 months. Please note: the use of this product after the end of the declared storage period may increase the risk of an allergic reaction.
Please note: Flowpoint is not recommended for use with some darker limestone, such as black limestone, as it can lead to a slight oxidisation. Call our expert team if you would like further advice on the ideal grout for darker limestone.
How many bags of Flowpoint Smooth will I need?
The number of bags of Flowpoint Smooth you'll need depends on the area in square metres of your patio, the width & length of your slabs, & the width and depth of your joints. As a general rule, for porcelain tiles 600mm x 900mm; with joints 5mm x 20mm you'll use one bag of Flowpoint per 30m2. For a mixed pack of sandstone slabs you'll need approximately one bag per 12-20m2, granite setts use more Flowpoint due to their size and depth - you'll need one bag per 1.5-2m2. For an accurate calculation, please refer to our calculator above.

In colder (click link for our article on grouting in colder temperatures) or wetter conditions, curing may take longer, while warmer temperatures can accelerate the process (click the link for more info). Proper curing ensures durability and long-term performance, making it crucial to follow manufacturer guidelines for optimal results.
Will Flowpoint Smooth Grout Stain My Paving?
Flowpoint Paving Grout is designed to be stain-free and resistant to efflorescence—provided it’s applied correctly and in line with the manufacturer’s instructions.
Staining is not a fault of the product, but typically a result of installation errors. Common causes include:
- Skipping a paving primer like Ultrascape Pro-Prime
-
Not lightly misting the slabs with water during application
-
Over-watering the grout mix, or leaving water sitting on the surface or in the joints
These issues can lead to grout haze, surface staining, or uneven color patches—which can be very difficult to clean once set.
How to Avoid Staining with Flowpoint Smooth Paving Grout!
Keep your paving looking its best with these simple best practices:
1. Prime before you grout
Use a high-quality primer such as Ultrascape Pro-Prime to help the paving bond to the mortar bed and block any moisture or stains from migrating through.
2. Keep slabs misted
Throughout the grouting process, lightly mist your slabs using a garden hose with a rose head or a spray bottle. This prevents premature drying and surface residue.
3. Watch your water
Avoid adding too much water to the grout mix, and don’t let water collect on the surface or in the joints. Too much water can result in cracking, staining, and a patchy finish.
4. Use the right tools
Apply the grout with a neoprene squeegee to push the material deep into the joints while clearing excess from the slab surface.
✅ Flowpoint Smooth doesn’t cause staining when used correctly.
Following proper installation steps will ensure a clean, consistent finish—free from haze, residue, or discolouration.
What is the Shelf Life for Flowpoint?
Shelf life from date of manufacture printed on the bag, unopened in the above conditions, for sealed bags is 8 months. Please note: the use of this product after the end of the declared storage period may increase the risk of an allergic reaction.
Please note: Flowpoint is not recommended for use with some darker limestone, such as black limestone, as it can lead to a slight oxidisation. Call our expert team if you would like further advice on the ideal grout for darker limestone.
How many bags of Flowpoint Smooth will I need?
The number of bags of Flowpoint Smooth you'll need depends on the area in square metres of your patio, the width & length of your slabs, & the width and depth of your joints. As a general rule, for porcelain tiles 600mm x 900mm; with joints 5mm x 20mm you'll use one bag of Flowpoint per 30m2. For a mixed pack of sandstone slabs you'll need approximately one bag per 12-20m2, granite setts use more Flowpoint due to their size and depth - you'll need one bag per 1.5-2m2. For an accurate calculation, please refer to our calculator above.

How do I mix & apply Flowpoint Smooth Paving Grout?
Follow these simple ten steps to use Flowpoint slurry grout to fill paving joints:- Firstly clean the paving slabs and joints so they are free from debris and any excess water
- Pre-soak the paving joints & surfaces with water to ensure they are damp – a light spray of water should be perfect
- Pour the Flowpoint powder into a bucket and add 4.25 litres of water
- Mix with a force action mixer for 3–5 minutes, until the consistency is smooth and free of clumps
- Before pouring the slurry mix, ensure that the area is still damp, apply the mixture immediately by carefully forcing Flowpoint into the joints using a rubber squeegee. Flowpoint can set within as little as 15 minutes (at temperatures of 20oC) so you will need to be quick, but careful
- Move the Flowpoint slurry across the patio surface to top-up joints where the mortar has sunk
- Use the rubber squeegee to remove as much of the paving grout from the surface of the slabs – still keep the surfaces constantly damp to prevent the grout from hardening
- Use a brush and plenty of water (or alternatively a sponge machine) to remove any grout that has hardened on the paving surfaces
- Once the mortar is dry (after about 30 minutes - depending on temperature), clean the surface of paving slabs thoroughly to remove any spots of mortar and prevent staining, you'll be looking for clean water running of the patio
- The pavers are ready to walk on after one hour and can receive car traffic after four hours
