FAQ

Why the epoxy filler does not harden?

Possible causes

  • Incorrect proportion of base and herdener,
  • Too low temperature of ambient and surface (less than 10ﹾC),
  • Mixing two components from two different manufacturers,

How to prevent

  • Apply the correct proportions of components
  • Maintain steady temperature (around 20ﹾC) during the whole hardening process,
  • Use base and hardener from the same manufacturer

How to remove

  • The uncured mass requires complete removal from the surface.

Why the resin does not harden?

Possible causes

  • Too low temperature of ambitne,
  • Incorrect proportion of base and herdener,
  • Mixing two components from two different manufacturers

How to prevent

  • Apply the correct proportions of components
  • Maintain steady temperature (around 20ﹾC) during whole hardening process,
  • Mix the products thoroughly and bleed the mixture.

How to remove

  • The uncured mass requires complete removal from the surface.

Why does the paint have no adhesion?

Possible causes

  • Wrong surface preparation,
  • Skipping the primer in the system application process,
  • Use of universal thinners or replacements ,
  • Paint incompatibility.

How to prevent

  • Correct surface preparation (grinding, clearing, degreasing),
  • Use primers which improve adhesion of paints,
  • Use thinners which are dedicated to each paints,
  • Use of paints which are compatible to each other.

How to remove

  • Grind, clean and paint again.

Why the paint does not have the right flow?

Possible causes

  • No thinning, wrong thinner or wrong amount of thinner
  • Wrong type of roll or brush (wrong bristle lenght)
  • Applying too much or too Little paint,
  • During painting process temperature was too high or the air was too dry,
  • Incorrect preparation of too porous surface,
  • Incorrect proportion of thinner.

How to prevent

  • Use a brush/Toller suited to the type of surface or paint,
  • Use thinner which is dedicated to the type of application and paints
  • Use thinning proportions which was indicated by manufacturer,
  • Paint in right atmosphere conditions indicated by manufacturer,

How to remove

  • Grind, clean and paint again.

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,

Contamination in topcoat paint?

Possible causes

  • Inaccurate surface cleaning before paint application,
  • Incorrect painting tools preparation (brush and roll),
  • Performing work in a place exposed to constant contact with dust.

How to prevent

  • Careful surface preparation (grinding, clearing, degreasing),
  • Careful painting tools preparation before use,
  • Maintain clean work environment

How to remove

  • Grind, clean and paint again.

Why did the polyurethane topcoat become dull?

Possible causes

  • Too short time for evaporation of the thinner,

How to prevent

  • Maintain the right conditions for complete evaporation of the thinner,

How to remove

  • Mat the surface, degrease and apply the paint according to the rule (right conditions and thinning proportions)
  • Polish surface if needed.

Why despite the use of antifouing paint the bottom of the boat is overgrown?

Possible causes

  • Too thin layer of antifouling paint,
  • Choosing the wrong antifouling to type of a boat or yacht
  • Thinning of antifouling paint,
  • Incorrect surface preparation before antifouling application.

How to prevent

  • Apply the right layer thickness of paint indicated by manufacturer,
  • Choose antifouling dedicated to type of boat or yacht and suitable for the type of water,
  • Do not thin antifouling because of the risk of reducing effectiveness,
  • Careful surface preparations (grinding, clearing, degreasing),

How to remove

  • Wet grinding, apply new layers of antifouling paint.
  • Use C1 shell and fouling remover.
