Product description "Polyester repair kit"

  • 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 set includes:

  • a polyester structural resin
  • hardener
  • fibre glass mat (0,25m2)
  • disposable gloves
  • a brush and a cup with a scale for easy dosing of ingredients
  • instructions for repair

Surface preparation

  • Prepare a suitable piece of glass mat (approximately 2 cm beyond the damaged area).
  • Degrease the surface and sand it with P80-P180 sandpaper. Remove dust and degrease again.
  • Apply the prepared resin mixed with the hardener to the cleaned area with a brush.
  • Apply the prepared mat or fabric pieces. Thoroughly saturate the glass mat with resin, pressing with a brush or roller to completely remove air bubbles from the repair area.
  • If necessary, apply multiple layers of mat or fabric using a similar method.

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

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

Further work

For finishing laminated sections, we recommend using products such as:

  • Sea-Line® epoxy fillers,
  • then Sea-Line® epoxy primers,
  • and finally Sea-Line® topcoats.

    • 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
