Block Paving Sealer - Silk 25ltr

Technical Information

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 30°C or below 5°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.

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 available on request.

Customer Reviews

Excellent Product, friendly and polite people to deal with.

This company provide good service and the products do a great job, its down to you to get the best results by doing the prep work thoroughly ,on older blocks you will need really 3 coats if they have never been sealed can work out expensive but the results are worth the extra coat or that extra drum you will then have a driveway as good as new and be the envy of your neighbours,dont just sweep sand back in it needs wacking and brushing several times the results will be worth the extra time you spend doing all that prep work .

I received the order today - a very quick delivery. Smartseal rang me just after I made the on-line order to check that I had ordered the right stuff (which I hadn’t) and pointed me in the right direction. Thank you both for your vigilance and for an excellent service. I would have no hesitation in recommending Smartseal.

First class service - product arrived next day as arranged. Product gave a very good appearance to block paving. On the face of things looks very good but it's only been sealed for a couple of weeks and therefore its probably too early to give any definitive review at this time. Will be interested to see how its standing up at the end of the summer
