RASTRENGTHENER is a premium eco friendly VOC-free stone sealer ideally suited to masonry, stone and traditional lime based plasters. RASTRENGTHENER'S unique formula means it actually strengthens as time passes and its high resistance to alkalis make it perfect to control the absorption of humidity in walls and ceilings, it can be used as a finishing and protective coating both internally and externally. RASTRENGTHENER is available in 1L, 5L and 25L plastic containers.
Ensure all new or old surfaces are sound, clean, dry and free from flaking paint, grease and similar contaminants. Mold or algae growth must be removed and treated. There should be no paint present on the surface to be treated.
Apply RASTRENGTHENER undiluted to the substrate with either a brush or roller, one even coat is sufficient. If a sheen is required apply a second coat. Clean tools after use with water. RASTRENGTHENER is clear but will change the colour of the substrate slightly.
