Internal Dampness: Ensure plaster surface is thoroughly clean with strong brush. Apply two coats of Damp Protek without any dilution maintaining the spreading rate of 4.6 to 5.0 sq. meters/kg/coat. Apply the 2nd coat at 90° to the first coat. Provide 4-hour re-coating period between the coats.
This would ensure correct consumption of material that will deliver a total dft of 170–150 microns.
Apply white cement based premium quality putty after the Damp Protek application for surface leveling of interior walls or can be left exposed. There is no need to stand the surface with emery paper Damp Protek coating before application of white cement-based putty.
Apply suitable premium internal wall paint for the effaced area after 4 days of the application of white cement putty. The system should cover an area well over and wide of the affected area. This will prevent water from affecting the adjacent areas.
Exterior Vertical and Horizontal surface: The substrate must be checked for soundness and non-structural cracks should be filled with suitable materials. All damaged portions need to be repaired. Ensure application is done on properly prepared surface.
Apply two coats of Damp Protek without dilution maintaining the spreading rate of 4.6 to 5.0 sq. meters /kg /coat. Apply the 2nd coat at 90° to the first coat. Provide 4 hours re-coating time interval between the coats. This would ensure correct consumption of material that will deliver a total dft of 170 – 150 microns. Allow the coating to air dry for 4 days.
(The spreading rate depends on film thickness applied, surface porosity, imperfections, and wastage during painting).
For exterior terrace/ wall surfaces, can provide extra waterproof by applying two coats (undiluted) of Rain Protek, if necessary.
Precautions:
1. Do not apply Damp Protek over surface affected with efflorescence.
2. All corners, gaps, joints, protrusions & outlets shall be coated with extra coat.
3. Damp patches at ground level or close to the ground could be caused by rising damp due to high ground water level, a damp proof coating with suitable polymer re-plastering is required on the external wall of the damp and internal walls to protect it from water.
4. In case of severe leakage in pipes or the tile joints of the wall adjoining bathroom/kitchen, have a plumber identify the source and repair it before treating the internal wall
5. Patch repair on roof & external walls provides temporary relief. Ideal recommendation solution is to go for comprehensive waterproofing on entire surface.
6. Remove masking tape, immediately after application.
7. Keep out of reach of children and eatables.
