Application Method

Stir the Base part thoroughly. Mix the 5 -10% Thinner in the paint as per our recommended ratio by volume. Stir the mix gently to attain homogeneity. Add thinner into the mix, if required depending on the application method and then stir gently for few minutes. Allow the mixture to stand still (maturation) for about 10-15 minutes to initiate the reaction. Strain the paint through Nylon filter cloth 400 mesh size and apply uniformly over the surface. All equipments used for above should be properly clean.

Application : By Brush / By Conventional Spray

For Brush application, generally no thinner is required to be added. However under adverse environmental condition about 5% by volume thinner can be added. Apply evenly in crossed manner and ensure the uniformity. Use quality brushes for paint application.

For Conventional Spray application:
  • Thinner : Type 006
  • Addition : 5 - 15%
  • Nozzle Orifice : 1.2mm – 1.5mm
  • Nozzle Pressure : 45 - 55 p.s.i.
