Application Procedure

Clean loose particles, dirt, grease and traces of adhering material from the wall surface with the help of sand paper, putty blade or by wire brush. For loose plastered areas, remove the defective material and re-plaster the area with BuildWell Ready-Mix Plaster. For ceiling/wall, which is not even, re-plaster it with BuildWell Ready-Mix Plaster to make them even. If any cracks in base plaster, fill it by using HomeSure Crack Filler. Moisten the surface with sufficient quantity of clean water.

Take 250-300 ml of clean water for 1 Kg of BuildWell Coarse Putty in a clean bucket. It is very important that BuildWell Coarse Putty to be added in water and not vice versa. Stir continuously by using an electric mixer or by hand to obtain a homogeneous lump-free paste. Allow the resultant paste to stand for about 10 minutes for additives to dissolve completely. Re-mix again for about 2 minutes. The paste is now ready for application. Use the prepared mix within 60 minutes.

It is very important and essential that the application area surface is pre-wet properly before the application of “BuildWell Coarse Putty”. The surface should be moist during application process. This ensures higher bonding, strength, easy workability and higher coverage within the surface. (In areas of high temperature and low humidity, light curing is recommended for at least 2 days).

Dampen the plastered wall surface with potable water. (Allow excess water to drain off completely). Apply the above mix with the help of a steel trowel or putty blade starting from bottom to upwards, followed by right to left direction to a thickness of about 3-4 mm and let it dry for at least 3 hours. If required more coats to cover unevenness, than it should be applied in multiple coat and each coat should not exceed less than 4 mm. For better results, it is always recommended to let the surface wall dry overnight for at least 10-12 hours. (Better adhesion to the base plaster). Once the finish coat is fully dried and set, apply two coats of BuildWell Wall Putty for better whiteness and smooth surface for primer and paint application. If required to remove any unevenness before any primer or paint application, level the surface with very fine emery paper not less than 300 no.
