A typical formulation is as follows : White / portland cement 50-60%Calcite /Titanium Dioxide 10-15% Calcium Chloride 2 - 5% China Clay 10%
  • PRECAUTIONS TO BE KEPT IN MIND WHILE APPLYING THE PAINT Water to be added just before use. Necessary to mix the paint from time to time while using it. Cement paints are mainly used over the plastered surfaces. Water to be sprikled time to time while setting paint Do not apply cement paint on surfaces which are already treated with whitewash, color wash and dry distemper unless the surface is thoroughly scraped and cleaned properly.

Efflorescence deposits must be cleaned also. Repair the patches Patches on painting area must be repaired by plastering followed by application of a coat of waterproofing cement paint on patches after wetting the surface completely. Clean existing paint/whitewash Clean old/existing surface, previously treated with whitewash and color wash thoroughly by scrapping all whitewash, color wash when water proofing cements paint is required to apply on existing surfaces.

Apply second coat of cement paint After the first coat is set at least for 24 hours, apply second coat by repeating application process of the first coat. Do proper curing Since hardening of paint film depends on the availability of moisture for chemical reaction with cement, the water should be sprinkled on painted surface at least for two days.
