Sarvottam Damp Lock is a fiber-reinforced elastomeric waterproofing coating for exterior surfaces, ideal for terraces, walls, balconies, and more. It involves surface preparation by cleaning and repairing cracks, followed by a self-priming coat (diluted 3:1 with water) and undiluted topcoats for durability. Fresh painting and repainting have specific coverage guidelines, and the finish includes two coats of Sarvottam Ultimate Protect Exterior Emulsion. It reduces surface temperature in white shades and provides excellent protection against environmental elements.
