Seal and Protect Surfaces

Clear Water Based Sealer 401 is a hardwearing, clear coating designed to protect a wide range of surfaces including masonry, concrete and internal timber.


When cured it provides a smooth washable surface that will keep the surface dry and protect it from stains and spills. 

Easy To Apply

This product can be applied over damp surfaces and the sheen level increased by applying additional coats as required. Two coats will provide a satin finish over smooth surfaces.


The advanced self cross-linking polymer cures after 72 hours and provides excellent chemical and water resistance and extended exterior durability.

Rapid Drying Time

Clear Water Based Sealer 401 is a rapid dry coating allowing the applicator to apply multiple coats in a single day.


Wet on wet application is possible where projects need to be completed in a short time.


Allow the coating to turn clear before applying subsequent coats.

Anti-Slip Additive

This sealer may become slippery when wet on some surfaces such as smooth pavers and terracotta or ceramic tiles. An anti-slip powder can be added to the final coat to increase texture and reduce slip hazards when used on steep grades or surfaces subject to frequent wetting with water.


More information on our anti-slip powder can be found on our product page.
