Patio Sealer Technical Data Sheet

Suitable for outdoor stone and concrete Seals and protects against staining from water, oil-based dirt and grime.

General product description

Patio Sealer provides an optimum all-round protection for porous building materials. This single product provides water and oil repellent protection for walls, flooring and roofing. Can be used inside and outdoors on both highly porous and low porosity materials e.g. limestone, granite, sandstone, marble and slate and surfaces subject to high levels of foot traffic including pavements, pedestrian precincts, patios, swimming pool decks, stairways and car parking areas. A non-film-forming surface impregnation, where the surface remains permeable to air and water vapour. Does not alter the surface colour. Aesthetics and composition of the treated material remains unchanged. A treated surface becomes UV-resistant and will not discolour with age.

Advantages and characteristics

A surface treated with this sealer will wear better over time and be easier to maintain. This treatment also offers a solution to the main causes of deterioration, like atmospheric pollution, grease-type dirt, penetration of liquids, graffiti and also makes chewing gum easier to remove.

Water-borne fluoropolymer dispersion.
