Sika® Patio Seal is a low odour water based acrylic coating used to seal and protect patios, paths, natural stone, concrete and block paving from the effects of sunlight, water, oil, petrol and organic growth. The milky solution dries to hard wearing water repellent film which gives a low sheen slip resistant finish which will reduce dirt pickup and facilitate easier cleaning. The product is safer to use than conventional solvent based products, i.e. it is non- flammable and will not harm plants and animals when used as directed.
