Acrylic liquid waterproofing is the more traditional route of waterproofing, using a water-based, acrylic waterproofing compound. The product Roofseal KG40 is a polyester reinforced pure acrylate waterproofing membrane, which means that it can be effectively applied to semi stable substrates, resulting in a monolithic and continuous membrane. The product is a fully bonded water-borne acrylate, allowing tremendous versatility and ease of application and repair. Used together with a geo-fabric membrane, it provides long-lasting waterproofing for all areas where applicable such as roofs, walls etc. Application is simple, however before starting GAST ensures that the area to be waterproofed is sound, stable and free of detritus, oil or any other substance that may prevent the system from achieving a good bond to the substrate.
