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.

    Our FAQ answers to frequently asked questions

    Can I add more hardener to speed up the reaction?

    Do not add more hardener, because after the base has cured, the remaining hardener will react with subsequent layers, which will be applied to the surface and cause defects. For the product to work properly, please follow the proportions given by the manufacturer.

    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.

    Can I paint the bottom of the boat with polyurethane paint?

    Yes, you can paint the bottom of the boat with polyurethane paint due to its high mechanical strength. We recommend this solution when the boat is not launched for a long time and is not exposed to fouling.
