Protecting Your Driveway and Patio with Polyurethane – Trade Supplies UK

Q: Will Extreme Seal darken my paving?

The final appearance depends on the finish you choose. Wet Look sealers enhance the colour of the paving and add a subtle gloss, while Matt Look sealers preserve a more natural appearance with minimal colour change. Always test the product on a small, inconspicuous area before full application.

Q: Is anti-slip necessary for driveways?

Not always. Anti-slip additives are generally recommended for sloping driveways, ramps, or areas that regularly become wet. On flat residential driveways, they are optional but can provide additional safety.

Q: How soon after new paving can I seal?

New block paving should normally be left for at least four weeks before sealing. This allows the paving to settle and any efflorescence to appear so it can be cleaned before the sealer is applied.

Q: Does this sealer prevent weed growth?

Yes. The sealer helps bind the jointing sand, making it more difficult for weed seeds and moss to establish. While it significantly reduces weed growth, periodic inspection and maintenance are still recommended.

Q: Will it resist hot tyre pick-up and oil stains?

Yes. Once fully cured, polyurethane-based paving sealers offer excellent resistance to tyre marks, oil, diesel, and many common contaminants, helping to protect driveways from everyday wear and staining.

Q: How often should I reseal my driveway or patio?

For most residential properties, resealing every 3 to 4 years is sufficient. Commercial premises and other high-traffic areas may benefit from resealing every 1 to 2 years, depending on wear and weather exposure.

Q: Is the surface slippery after sealing?

Wet Look sealers can create a smoother finish that may become more slippery when wet. Where additional grip is required, such as on slopes or steps, using an anti-slip additive is recommended.

Q: What safety gear is recommended during application?

When applying solvent-based sealers, wear suitable protective equipment including nitrile gloves, safety goggles, and an appropriate respirator. Work in a well-ventilated area and follow all safety instructions provided by the manufacturer.

When it comes to keeping your driveway, patio, or paved surfaces looking pristine and protected, choosing the right block paving sealer is essential.

How to Apply Block Paving Sealer for Best Results

1. Preparation

Jet-wash the surface to remove dirt, algae, and efflorescence.
Resand joints so they’re flush, brushing off excess.
Allow paving to dry for at least 48 hours (moisture content <4%) before sealing.

2. Priming (For Porous Surfaces)

On very absorbent blocks or clay pavers, mist a thinned 10% first pass to reduce soak-in.

3. Mixing

Stir the sealer for 2 minutes.
For an anti-slip finish, slowly add the silica grit while stirring until fully dispersed.

4. Application

Apply the first coat with a solvent-resistant roller, brush, or pump sprayer in a thin, even film.
After 4–6 hours, apply a second coat in a cross-direction. For maximum wet look gloss, a third clear coat can be added.

5. Curing

Protect from rain for at least 6 hours.
Allow 12 hours for light foot traffic and 48 hours for vehicles.
Full chemical cure and maximum durability are achieved in 7 days.
