Polyester resin

To obtain a fully-fledged and adequately strong laminate, use a 2:1 weight ratio of resin to glass mat for polyester or a 1:1 weight ratio of resin to glass fabric.To finish laminated surfaces we recommend using Sea-Line® fillers, Sea-Line® epoxy primers, Sea-Line® topcoats or a Sea-Line® gelcoat repair kit.

Our FAQ
Answers to frequently asked questions

Can I degrease surfaces with acetone?

We do not recommend degreasing the surface with acetone, because acetone evaporates very quickly, which affects the quality of cleaning the painted surface.

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,

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.
