Step 1 : Surface Preparation
Ensure surface is thoroughly clean, dry and free from all loose dirt, chalk, grease, fungi, algae and flaking paint. This can be achieved by brushing with a wire /stiff coir brush followed by water jetting, if required. Fill up all minor cracks and defects with suitable Dulux Aquatech Crack Fillers
Step 2 : Application process
Apply Dulux Polyputty paste from the bottom in upward direction uniformly with the help of a steel trowel/putty blade to ensure less wastage. Allow at least 3 hours drying time for the applied polyputty paste. After drying of the first coat rub the surface gently with the putty blade in order to remove loose particles. Apply the second coat after the first coat is fully dried or set. Preferably, leave the surface to dry overnight.
Step 3 : Drying time
Apply the second coat after the first coat is fully dried or set. Preferably, leave the surface to dry overnight.
