Surface Preparation:
• For the Interior surfaces, existing POP or putty must be removed till the plaster surface is exposed.
• The surface must not be loose, it should be strong and free from dirt, dust, chalk, loose particles. This can be achieved by brushing with a wire/stiff coir brush, followed by water jetting if required or move the loose particles with air compressor.
• Oil or grease must be removed with degreasing solvents; otherwise it will hamper the performance of the product.
• Any cracks in the plastered surface should be filled with Aquatech crack fillers as per the requirement and other damaged surface should be repaired with cement and sand mixture or polymer modified repair mortar.
• Before application of the product, the surface must be pre wetted and saturated to a surface dry condition, which improves the bonding of water block 2K to the substrate.
Mixing Ratio: Waterblock 2K Solid Additive: Waterblock 2K Liquid Additive = 2:1 (By weight)
Mixing Procedure:
• After opening the mono carton, shake the liquid component properly for a homogeneous mixing. Transfer the entire liquid component to a clean mixing vessel and then slowly start adding the powder component under constant stirring with a stirrer using a pneumatic or electrical power tool (1KW) at slow speed of 200-300 rpm for 5-6 mins to get a homogeneous, free flowing and lump free mixture/slurry.
Application:
Interior Wall Application:
• Two coat of mixed slurry of Aquatech Waterblock 2K to be applied to the set concrete/Plaster @ 10 - 15 sqft/Kg by a masonry brush or appropriate powder spray equipment.
• The second coat should be applied when the first coat is completely dry. Drying time after the first coat should be 1-2 days.
• For Damp walls, ensure the full wall is applied with Aquatech Waterblock 2K.
• The treated area should be protected from direct sunlight and to be damp cured by covering with damp hessian or similar system.
• Allow the second coat to dry hard for 4-6 days. After proper drying the normal painting procedure for Primer, putty, Primer & top coat can be followed.
Concrete slabs or roof slabs:
• Two coat of mixed slurry of Aquatech Waterblock 2K to be applied to the set concrete/Plaster @ 5-6 sqft/Kg by a masonry brush or appropriate powder spray equipment.
• The second coat should be applied when the first coat is completely dry. Drying time after the first coat should be 1-2 days.
• Allow the second coat to dry hard for 4-6 days.
Water tanks and Swimming pools:
• Two coat of mixed slurry of Aquatech Waterblock 2K to be applied to the concrete/plastered surface @ 6- 7 sqft/Kg by a masonry brush or appropriate powder spray equipment.
• The second coat should be applied when the first coat is completely dry. Drying time after the first coat should be 1-2 days.
• Allow the second coat to dry hard for 4-6 days.
• For water tanks, both sides of the tanks should be covered for a better result.
• The treated area should be protected from direct sunlight and to be damp cured by covering with damp hessian or similar system.
Marbles/Stones:
• One coat of Aquatech Waterblock 2K slurry to be applied at the bottom side of the marble @ 2 mm + thick at coverage of approximately 5 sqft/Kg
