How to use

Surface Preparation

All the surfaces must be cleaned and made free of dust, dirt, moss, oil, grease and other loose particles. All pot holes and surface defects shall be repaired with a suitable concrete repair mortar from the Polycrete* range. Polytherm AC does not require priming and can directly be applied onto the surface. In case of highly porous surface, a priming coat is recommended to seal the pores and stabilize the surface. The primer coat can be produced on site by diluting Polytherm AC 1 to 1 with water. Apply the primer coat @ 5m2/L and allow to dry.


Once stirred, Polytherm AC should be immediately applied either by brush, roller or industrial sprayer. It is recommended that coating be applied in a minimum of two coats. Should not be applied if relative humidity exceeds 95%. Each subsequent coat shall be applied only after the previous coat dries off completely. After application the coating must be back rolled to reduce surface irregularities and improve bonding. 


Store in a cool, dry place and keep away from all sources of heat and sunlight. In tropical climates, store in air condition rooms. The shelf life is up to 12 months in unopened condition and if stored as per recommendations. Excessive exposure to sunlight, humidity and UV will result in the deterioration of the quality of the product and reduce its shelf life.
