Used this patio sealer in the past and was not disappointed

By Chris King

Simply the best sealer around. Easy to apply, better finish than other brands and lasts way longer. My patio looks a million dollars with Smart Seal. Well worth every penny. ?

By Marie Lovelady

This patio sealant does an excellent job, it keeps our patio looking good and its easy to apply and we find we only need to power wash once in spring and any dirt is washed off easily.

Technical

Application

Smartseal Patio sealer can be applied using a sprayer unit or roller, at a rate of 4 m2 per litre (pavers) 1st coat & 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. 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 cleaning fluid after use.

De-icing salts should not be applied directly on Smartseal block paving, patio 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 Patios should be swept clean, ensuring there is sufficient pointing 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 Moss Clear. Oil should be removed using Smartseal 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 Patio 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.
