Product description "Polyester resin"

  • Sea-Line® structural polyester resin is recommended for laminating, reinforcing the surface, and patching holes and damage – especially in situations where the most important is a fast repair time.
  • In conjunction with the glass mat, it is used for manual repairs of damage.

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.

The resin is available in 3 sets:

  • Set of 250 g
    contains a polyester structural resin with hardener, fibre glass mat (0,25m2), disposable gloves, a brush and a cup with a scale for easy dosing of ingredients and instructions for repair.
  • Set of 500 g
    contains a polyester structural resin with hardener and a cup with a scale for easy dosing of ingredients and instructions for repair.
  • Set of 1 kg
    contains a polyester structural resin with hardener and a cup with a scale for easy dosing of ingredients and instructions for repair.

Surface preparation

To achieve a full-quality and sufficiently strong laminate, use the following weight ratio:

  • For mats, use a 2:1 ratio – 2 kg of polyester resin for 1 kg of glass mat
  • For fabrics, use a 1:1 ratio – 1 kg of polyester resin for 1 kg of glass fabric

Further work:

For finishing the laminated sections, we recommend using materials such as:

  •  Sea-Line® epoxy fillers
  •  Sea-Line® epoxy primers
  •  Sea-Line® topcoats

    Our FAQ answers to frequently asked questions

    Do you have to paint the scratched side of the boat?

    If the scratches are not deep, then we can renew the scratched side by polishing with Sea-Line polishing pastes. Above the waterline, when the scratches are not deep, the surface can be repaired with a DRY FAST gel coat filler. Deep scratches should be filled with epoxy filler (selected depending on the requirements of the scratched surface), painted with a primer and then painted with topcoat.

    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 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.
