About the product

ProJoint PRO-410 Paving Sealer

A professional solvent-based penetrating paving sealer and colour enhancer with a matt finish.

ProJoint PRO-410 Colour Enhancing Paving Sealer is a high-quality, solvent-based surface sealer that can be applied to all types of natural stone. It impregnates the stone and protects surfaces from water penetration, staining and the effects of natural weathering while remaining breathable.

PRO-410 enhances the natural colours within the stone without changing the texture of the surface. It can be used on virtually all porous surfaces, particularly high-quality natural stone, and is suitable for outdoor and indoor applications.

We’re a small, family-run business — I’m Cleo, the owner, with over 25 years in the construction industry working with businesses including Tarmac and Instarmac. My team and I have seen a lot of paving and sealing projects over the years, so we’re happy to help you check whether PRO-410 is right for your surface before you order.

What is ProJoint PRO-410 used for?

PRO-410 is designed for impregnating, sealing and binding porous natural stone, concrete, screeds, block paving, brickwork and masonry. It is a useful choice for porous paving, patios, paths, driveways and other surfaces that need protection from water penetration, staining and weathering while retaining a breathable finish.

  • Professional-grade solvent-based repellent for porous natural stone and concrete
  • Breathable protection
  • Enhances, seals and protects
  • Helps resist dirt, grime and algae
  • Long-lasting protection and UV stable
  • High surface penetration
  • Matt finish and single-coat application
  • High coverage rate of approximately 4.5–7m² per litre, depending on substrate porosity
  • Available in 1 litre, 5 litre and 25 litre containers

Important before using PRO-410

IMPORTANT: Freshly laid paving must be left for a minimum of 8 weeks to allow moisture within the paving to disappear before sealing.

Always test PRO-410 on a small, inconspicuous area before treating the whole surface. PRO-410 is not designed for porcelain paving and is not recommended as a replacement for a pre-grout sealer. If you need to protect paving before grouting, use the appropriate ProJoint Pre-Grout Sealer instead.

How to use ProJoint PRO-410

  1. IMPORTANT: Leave freshly laid paving for a minimum of 8 weeks to allow moisture within the paving to disappear.
  2. Clean the paving thoroughly before application. We recommend PaveCare Paving & Driveway Cleaner for cleaning paving and driveways before sealing.
  3. Always test PRO-410 on a small, inconspicuous area first and check the result before treating the whole surface.
  4. Apply PRO-410 as a single coat, following the current product instructions and technical datasheet.
  5. Work carefully across the prepared surface so the sealer penetrates the porous substrate and the matt finish remains even.

Always read the current technical datasheet and health and safety information before use. A full datasheet is available on request.

ProJoint PRO-410 FAQs

I’m Cleo, owner of The Paving Experts, with over 25 years in the construction industry working with businesses including Tarmac and Instarmac. The answers below come from the questions we’re asked by contractors and homeowners about sealing porous paving.

What is ProJoint PRO-410?

PRO-410 is a professional-grade, solvent-based penetrating paving sealer and colour enhancer for porous natural stone and suitable concrete surfaces. It helps protect against water penetration, staining, dirt, grime, algae and natural weathering while enhancing natural colour. It provides a matt finish rather than a glossy or wet-look appearance.

What type of paving can PRO-410 be used on?

PRO-410 is designed for porous natural stone and concrete paving, and is particularly suited to high-quality natural stone. Natural stone varies in porosity and appearance, so always test a small, inconspicuous area first.

Can PRO-410 be used on porcelain paving?

No. PRO-410 is not designed for porcelain paving. Porcelain has a very low-porosity surface and requires a product specifically formulated for porcelain where sealing is appropriate. Contact us before ordering if you are unsure which product you need.

Can PRO-410 be used on concrete?

Yes. PRO-410 can be used on porous concrete surfaces, subject to the condition and suitability of the surface. Always carry out a test area first.

Does PRO-410 change the colour of natural stone?

It is designed to bring out the natural colours within the stone. It does not create an artificial colour, but the stone may appear richer or deeper once sealed. Always test an area first.

Does PRO-410 give a glossy finish?

No. PRO-410 has a matt finish and does not create a high-gloss or artificial-looking surface.

Will PRO-410 change the texture of my paving?

No. It penetrates into the surface rather than creating a thick surface coating and is designed to maintain the existing texture.

Is PRO-410 breathable?

Yes. PRO-410 is a breathable penetrating sealer, allowing paving to release moisture vapour while providing protection against water penetration.

How long should I wait before sealing newly laid paving?

A minimum of 8 weeks. Freshly laid paving must be left for at least 8 weeks to allow moisture within the paving to dissipate before PRO-410 is applied. Do not rush the sealing stage.

Can PRO-410 be used on existing paving?

Yes, provided the paving is suitable, clean and suitably dry. Remove dirt, algae, previous treatments and contaminants appropriately, then test a small area first.

Can PRO-410 be used on driveways?

Yes, provided the driveway is constructed from a suitable porous natural stone or concrete surface. It can help protect against water penetration, staining, dirt, grime and natural weathering.

Can PRO-410 be used on patios and garden paths?

Yes. It is well suited to porous natural stone patios, paths and other external paving areas, helping enhance the natural colour while providing protection.

Can homeowners use PRO-410 themselves?

Yes. Competent DIY customers can use it provided they carefully follow the preparation and application instructions. If you are unsure whether your paving is suitable, send us a photo or contact us before applying it.

Is PRO-410 suitable for paving contractors?

Yes. It is available in 1 litre, 5 litre and 25 litre containers, making it suitable for domestic projects, landscaping work and larger paving contracts.

How much PRO-410 will I need?

Coverage is approximately 4.5–7m² per litre, depending on the porosity of the paving. As a guide, a 5-litre container could cover approximately 22.5–35m², depending on the substrate.

Is PRO-410 a single-coat product?

Yes. PRO-410 is designed for single-coat application. Correct preparation is particularly important with highly porous natural stone.

Does PRO-410 protect against staining?

Yes. It helps protect against staining, dirt and grime, water penetration and natural weathering. It is not stain-proof, so spills should still be cleaned quickly.

Does PRO-410 help prevent algae?

It provides resistance against dirt, grime and algae, helping suitable paving stay cleaner for longer. It will not prevent organic growth completely, as shade, moisture and vegetation can contribute to algae growth.

Is PRO-410 UV stable?

Yes. PRO-410 is UV stable and provides long-lasting protection against natural weathering.

Does PRO-410 make paving waterproof?

No. It is a water-repellent penetrating sealer, not a waterproofing membrane. It should be used alongside correct paving construction and drainage.

Can PRO-410 be used instead of a pre-grout sealer?

No. PRO-410 is not recommended as a replacement for a dedicated pre-grout sealer. For protection before grouting, use a product specifically designed for pre-grouting protection, such as ProJoint Pre-Grout Sealer.

Can I apply PRO-410 before grouting?

No. PRO-410 is not designed as a pre-grout sealer. Contact us about the appropriate product for your paving.

Why should I test PRO-410 first?

Natural stone varies in colour, density, porosity and texture. A test area shows how the sealer affects your particular stone before treating the entire area.

What happens if I seal paving that is too wet?

The paving needs to be suitably dry before sealing. Excess moisture can affect performance and the finished result. This is why the minimum 8-week period for freshly laid paving is important.

Can PRO-410 be applied in all weather conditions?

No sealer should be applied without considering the conditions. The surface should be clean and suitably dry, and solvent-based product instructions regarding ventilation, weather and application conditions should be followed.

Is PRO-410 suitable for high-quality natural stone?

Yes. It is particularly suited to porous, high-quality natural stone, enhancing natural colour while providing protection. Always test first.

What sizes does PRO-410 come in?

PRO-410 is available in 1 litre, 5 litre and 25 litre containers.

Can PRO-410 be used on commercial projects?

Yes, provided the paving is a suitable porous natural stone or concrete substrate. It is suitable for a range of commercial landscaping and paving projects.

What is the biggest mistake to avoid when using PRO-410?

Do not seal paving before it is ready. Newly laid paving must be left for a minimum of 8 weeks, and the surface should be appropriately clean and dry. Always test a small area first.

Is PRO-410 suitable for every type of natural stone?

It is designed for porous natural stone, but different stones can react differently to colour-enhancing sealers. Contact us before applying it if you are unsure about a particular stone.

I’m a contractor. Can you help me work out how much I need?

Absolutely. Give us the approximate square metreage, the type of paving and, ideally, a photo of the stone. We’ll help work out likely coverage.

I’m a homeowner and I’m not sure if my paving can be sealed. Can you help?

Of course. Send us a photo, tell us roughly how old the paving is and what you hope to achieve, and we’ll do our best to point you in the right direction.

Yes. It helps protect against staining, dirt and grime, water penetration and natural weathering. It is not stain-proof, so spills should still be cleaned quickly.

Does PRO-410 help prevent algae?

It provides resistance against dirt, grime and algae, helping suitable paving stay cleaner for longer. It will not prevent organic growth completely, as shade, moisture and vegetation can contribute to algae growth.

Is PRO-410 UV stable?

Yes. PRO-410 is UV stable and provides long-lasting protection against natural weathering.

Does PRO-410 make paving waterproof?

No. It is a water-repellent penetrating sealer, not a waterproofing membrane. It should be used alongside correct paving construction and drainage.

Can PRO-410 be used instead of a pre-grout sealer?

No. PRO-410 is not recommended as a replacement for a dedicated pre-grout sealer. For protection before grouting, use a product specifically designed for pre-grouting protection, such as ProJoint Pre-Grout Sealer.

Can I apply PRO-410 before grouting?

No. PRO-410 is not designed as a pre-grout sealer. Contact us about the appropriate product for your paving.

Why should I test PRO-410 first?

Natural stone varies in colour, density, porosity and texture. A test area shows how the sealer affects your particular stone before treating the entire area.

What happens if I seal paving that is too wet?

The paving needs to be suitably dry before sealing. Excess moisture can affect performance and the finished result. This is why the minimum 8-week period for freshly laid paving is important.

Can PRO-410 be applied in all weather conditions?

No sealer should be applied without considering the conditions. The surface should be clean and suitably dry, and solvent-based product instructions regarding ventilation, weather and application conditions should be followed.

Is PRO-410 suitable for high-quality natural stone?

Yes. It is particularly suited to porous, high-quality natural stone, enhancing natural colour while providing protection. Always test first.

What sizes does PRO-410 come in?

PRO-410 is available in 1 litre, 5 litre and 25 litre containers.

Can PRO-410 be used on commercial projects?

Yes, provided the paving is a suitable porous natural stone or concrete substrate. It is suitable for a range of commercial landscaping and paving projects.

What is the biggest mistake to avoid when using PRO-410?

Do not seal paving before it is ready. Newly laid paving must be left for a minimum of 8 weeks, and the surface should be appropriately clean and dry. Always test a small area first.

Is PRO-410 suitable for every type of natural stone?

It is designed for porous natural stone, but different stones can react differently to colour-enhancing sealers. Contact us before applying it if you are unsure about a particular stone.

I’m a contractor. Can you help me work out how much I need?

Absolutely. Give us the approximate square metreage, the type of paving and, ideally, a photo of the stone. We’ll help work out likely coverage.

I’m a homeowner and I’m not sure if my paving can be sealed. Can you help?

Of course. Send us a photo, tell us roughly how old the paving is and what you hope to achieve, and we’ll do our best to point you in the right direction.

How to apply ProJoint PRO-410

IMPORTANT: Freshly laid paving must be left for a minimum of 8 weeks to allow moisture within the paving to disappear before sealing.

  1. Leave freshly laid paving for a minimum of 8 weeks to allow moisture within the paving to disappear.
  2. Clean the paving thoroughly before application. We recommend PaveCare Paving & Driveway Cleaner before sealing paving or driveways.
  3. Always test PRO-410 on a small, inconspicuous area first before treating the whole surface.
  4. Apply PRO-410 as a single coat, following the current product instructions and technical datasheet.
  5. Work across the prepared porous surface carefully so the sealer penetrates evenly and the matt finish remains consistent.

PRO-410 is suitable for appropriate porous natural stone, concrete, screeds, block paving, brickwork and masonry. It is not designed for porcelain paving and is not a replacement for the dedicated ProJoint Pre-Grout Sealer. Always read the current technical datasheet and health and safety information before use.

PRO-410 is a professional-grade, water-based sealer designed to protect natural stone, porcelain, and concrete paving. It repels water, oil, and dirt, making surfaces easier to maintain.
