Amount

Providing and applying water retarding treatment/ silicon coating to the external surfaces of thr size stone masonary wall and cladding to prevent seepage of water throudh walls including scaffolding , washing the surface, curing , etc.. As per specifications and at all lifts. a) preparation of surface and removal of fungus and loose particles, cleaning with brushes and through acid wash, wherever necessary. b) Product Application: Base Coat (Primer): Apply SEAL PRIME PRIMER, a salt efflorescence and dampness-resistant primer, on the pointing area of the structure.The primer should be applied evenly to ensure complete coverage of the surface, offering resistance to salt efflorescence, moisture, and dampness. Top Coat (Water Repellent): After the primer has dried and cured, apply a transparent water-repellent and film-forming nano-emulsion.The nano-emulsion should be sourced from any of the following approved brands: Panache, Fosroc, Dr. Fixit, or any other equivalent brand as approved by the Engineer-in-Charge (EIC). The water repellent should be applied in a manner that ensures uniform coverage and effective film formation, providing long-lasting protection against water penetration. c)Application Method:Apply both the primer and nano-emulsion using a brush, roller, or spray method, as per the manufacturer's recommendations. Follow the recommended curing times for both the primer and the nano-emulsion for optimal adhesion and performance. d) Quality Control:Ensure that the materials used conform to the manufacturer's specifications and are sourced from authorized suppliers.The final outcome should provide a seamless, durable protective layer, resistant to water, salt efflorescence, and dampness.
