When it comes to painting your new houses or re-painting your present abode, everyone wants their house to look as bright and perfect as they had imagined it to be. Furthermore, the last thing one wants is to worry about how soon they will have to think about repainting the house.

This concern is even more relevant for the outer walls of your homes, as those are the walls which are exposed to rain and other wear and tear. This is where wall putty plays an important role. It helps in bringing out the true colour of the topcoat on your interior and exterior walls and helps them look bright and fresh for a long time.

Step 1: Remove all the loosely adhering material, like dirt, dust and oil etc. from the surface by using emery paper, putty blade or wire brush.

Step 2: Do remember to moisten the wall before putty application. You can do so with the help of a brush, hose spray, mug or a can.

Step 3: Slowly add 1 kg of Waterproof putty with 36-38% clean water (1Kg putty+360-380 ml of water) to make the paste. Mixing should be carried out by preferably a mechanical stirrer (3-5 minutes) to obtain a creamy consistency.

Step 4: Leave the  paste for 5 minutes after thorough mixing to get best results.

Step 5: The prepared paste should be used within 3:00 to 3:30 hours.

Step 6: Ensure that during application, substrate surface temperature should not exceed above 40 degrees centigrade.

Step 7: After drying the first coat of putty, rub the surface gently with a wet sponge or very gently with a putty blade in order to remove the loose particles.

Step 8: Wait for at least 3-4 hours to apply the next coat.

Step 9: Let it dry for 24 hours before topcoat application

Step 10: It is not recommended to rub the putty surface of final coat strongly with rough emery paper. However, if there is need to remove unevenness/patches before applying any kind of paint/distemper, gently level the surface with very fine water proofing emery paper of not less than 500 number to get a glossy white surface.
