Sika® CoolCoat Primer

Efflorescence resistance penetrating primer based on acrylic emulsion polymer

Sika® CoolCoat Primer Primer is a versatile water based primer comprising of self cross linking acrylic emulsion polymer and additives in water as a medium. This Primer can be used as as a seal coat for various water based Sika® Cool Coat, Sikagard® XT etc and where ever green construction is desired

  • Suitable Primer for internal and external surfaces
  • Smaller polymer particles penetrate deeply to provide excellent substrate adhesion
  • Suitable for porous substrates with over heating
  • High Alkali resistant - Due to self cross linking polymers it gives very high resistance to alkaline substrates and protect the top coat
  • Efflorescence resistance - Due to self cross linking polymers it gives very high efflorescence resistance

Application steps

APPLICATION

Stir well until a uniform consistency is achieved. Apply a single coat of Sika®- CoolCoat Primer on the cleaned substrate & allow it do dry.

The primer may become high viscous due to change in ambient conditions like temperature and humidity that might affect the consistency and increase consumption of the primer. Under such situation, a site modification by adding water is recommended by Sika®. In order to achieve application friendly consistency of the product. The dilution is fixed on the basis of site trials
