Is it necessary to always sand the surface between application of two different products?

We recommend to always sand the surface between applying two different products to ensure uniform surface roughness and adhesion of subsequent layers. The sanded surface should also be cleaned and degreased.

Why are the streaks formed?

Possible causes

  • Wrong viscosity and spraying technique,
  • Failure to maintain proper evaporation time and thickness of layers,
  • Incorrect spraying pressure,
  • Too low temperature of varnish, surface or space ,
  • Wrong thinner or hardener.

How to prevent

  • Apply the right type of application method indicated by manufacturer,
  • Use working spray guns,
  • Both the object and material must have room temperature of 20ﹾC,
  • Apply correct proportion of base and hardener.

How to remove

  • Grinding and polishing,
  • Grinding and painting,

Can I add more hardener to speed up the reaction?

Do not add more hardener, because after the base has cured, the remaining hardener will react with subsequent layers, which will be applied to the surface and cause defects. For the product to work properly, please follow the proportions given by the manufacturer.
