BITUMEN BASE PRIMER

This solvent base Bitumen Primer is recommended for use on all porous and nonporous surfaces. The function of primer is to help remove the dust particles and remain adhesive for sometime to allow sticking of final coats on top of it. It also provides durability, increases life, extra strength and furthermore acts as a binder between the surface and the materials applied thereafter.

It is to be applied on concrete as well as on bituminised surfaces. It can also be applied on metal surfaces prior to any other coatings such as Anti Corrosive Bitumen. It is used as a prime coat for Felts, Asphalt, Concrete & Steel work surfaces, Bricks, Plaster, Asbestos and prior to the application of Bitumen Emulsions or Solvent based materials.

1. Apply Primer to clean and sound surfaces.
2. Do not apply on wet surfaces. (for wet surfaces ask for water based Primer)
3. Allow to dry for 3 to 4 hours in summer and 7 to 8 hours in winter.
4. If the temperature is below 0° C then wait at least 24 hours before applying the actual coating.
5. This material can be applied with brush, roller or spray.

Immediately after use, clean the brush etc. with petrol, white spirit or naptha solvent.
