Smartseal Block Paving sealer can be applied using a sprayer unit or roller, at a rate of 2.0m2 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 20°C and foot traffic may be permitted after 4 hours. Vehicles should be kept off the sealed area for a minimum of 24 hours at 20°C. 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 25°C or below 12°C. All equipment should be cleaned with Smartseal cleaner fluid 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.



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.
