Recommended coverage
First coat: 2.0sq. metres per litre
Second coat: 3.5sq metres per litre
Application
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 23°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.

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.

Q: Hi I have a patterned concrete slab patio which Sealant is best to use I am looking for a shining finish. Thank You
A: You should use the imprinted concrete sealer in silk finish to seal your patterned concrete patio.
Q: I'm looking for a Silk Finish. Your "Block Paving Sealer SILK" seems to fit the bill, but I notice your "Block Paving Sealer Polyurethane (Commercial)" has double the protection lifespan. But this is a Matt finish. Do you do the latter in a Silk finish, or can I apply one coat of Matt, then the Silk over the top?
A: The polyurethane block paving sealer has more of a matt finish. You can apply the silk finish over the matt finish block paving sealer. Alternatively, you can apply two coats of the silk finish block paving sealer.
Q: How long would an unopened 25ltr can last? Does it have a sell by date?
A: An unopened tin of solvent based sealer stored correctly, will last many years and still be usable.

I have used smartseal products for 10 years now and use the block paving sealer silk to finish the drive off. After a good clean it has made the drive look like new again. Once every 5 years I do the drive.
I was recommended block magic for my slabs which were red and I gave them 2 coats , they look amazing.. I had to phone for advice and spoke to Ricky who had great knowledge and was very professional with his advice. Thanks Ricky
