By Jean Oakes

Excellent block paving sealer. Very nice finish to the driveway. Easy to apply with the professional roller kit.

By Simon Nash

The block paving sealer is a fantastic product

By DEAN HALL

Great product, the block paving sealer is easy to put down with roller, as others have mentioned, it has a very strong smell but went away after a few days. Looks great. The more coats the better coverage and greater protection. Sets the block paving off.

Second coat: 3.5sq metres per litre

Technical

Application

Smartseal Block Paving sealer can be applied using a sprayer unit or roller, at a rate of 2.5m2 per litre (pavers) 1st coat & 3.5 m2 per litre 2nd coat. A two-coat spray application is required to fully cover the jointing sand. The sealer will be tack free within 2 hours at 20C and foot traffic may be permitted after 4 hours. Vehicles should be kept off the sealed area for a minimum of 24 hours at 20C. These times may be increased or reduced depending on the ambient temperature. During the curing cycle, protect from rain. Do not apply when the ground temperature is above 23C or below 12C. All equipment should be cleaned with Smartseal tool cleaner after use.

Deicing salts should not be applied directly on Smartseal block paving or concrete sealers. Salt chemically reduces the temperature at which water freezes and will result in water ingress into the concrete. Subsequent freezing may result in the concrete seal being broken by the expansion of water as it freezes and white pitted areas may become visible.

NOT TO BE USED ON CLAY PAVERS

*** If your Block Paving has been previously sealed - to ensure compatibility, please contact us here before ordering: https://www.smartseal.co.uk/help-advice/contact-us.htm

Preparation

New block paving or cobble stone paving should be swept clean, ensuring there is sufficient well-compacted sand in the joints. Existing paving should be pressure washed to remove all surface debris. If the area is contaminated with weeds & moss then it should be treated with Smartseal Fungicidal Wash. Oil and other stains should be removed using Smartseal Cleaner / Oil Remover. The treated area should then be left to dry and the joints re-sanded & compacted to the lower edge of the paver chamfers with clean kiln-dried sand. Moisture in the paver & sand will inhibit penetration of the sealer and produce whiteness.

Technical & Test Data

Smartseal Block Paving sealer has been tested by the TRL (Transport Research Laboratory) and certified that it meets the SRV (Skid Resistance Value) for all categories of paving for local authority pedestrian areas and when heavily trafficked is suitable for special applications where risks of skidding are high as laid down in the UK Highway Authorities Tender Specification. Copies are available on request.

Specification Clause

Newly laid block or flagstone paving shall be treated with Smartseal block paving sealer to protect and stabilise jointing sand and enhance surface colour and increase abrasion resistance. All materials should comply with ISO9002 for Quality Assurance. All work should be carried out in conjunction with the manufacturers current technical data sheet and instructions for use.

Product FAQs

Q: Hi Do you have a product that can be used to seal clay blocks on my driveway Thanks

Calvin

A: Hi Calvin, We don't have anything for Clay Pavers unfortunately.

Response from Josh

Q: Is it possible to purchase a small amount of solvent cleaner (for matt paving block sealant)). Your reusable cleaning pack costs more than replacing my Hozelock sprayer, and I only hope to use your product once! If not, can you tell me which solvent is used (I used to teach chemistry). Many thanks.

Martin Scotchmer

A: The SDS sheet listing the list of ingredients will be next to the product. Any sprayer used for sealing with solvent based block paving sealer would need to be fitted with viton seals. The cleaning fluid is available in 5L. Hope that helps.

Response from George

Q: Hi, how much sealer would I need to cover 15m2? Rgds Donna

Donna

A: For two coats, recommended coverage is 2 m2 per litre 1st coat and 3.5m2 per litre 2nd coat. For 15m2 just over 10L would be correct.
