Polyester modelling filler

Mold-making polyester filler is primarily recommended for work on large surfaces above the waterline, in interiors, as well as on molds and models.

Polyester modelling filler is recommended for work on large area and molds. It has an extended pot life compared to other polyester fillers, making it easier to work on large surfaces. Has excellent adhesion to wide variety of surfaces. After curing creates resistance coat, in the same time it is easy to sand. Polyester fillers are recommended for area above waterline.

    We do not recommend using universal thinners. The use of a thinner with an unknown composition may result in loss of adhesion, lack of proper flow of paint and varnish defects.

    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 of paints which are compatible to each other.

    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
