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.

Our FAQ

Answers to frequently asked questions

Sea-Line yacht paints are designed for painting the surface of boats and yachts made of various materials, e.g. laminate, wood or steel. We do not have a certificate of the National Institute of Hygiene, which would allow the use of yacht paint to paint the tank with drinking water.

Sea-Line HARD and Sea-Line self-polishing antifouling are not intended for aluminum surfaces. They include copper oxide, which in contact with aluminum causes galvanic corrosion. Especially on aluminum, we offer ALU-PLUS self-polishing anti-fouling paint, which, in addition to excellent adhesion to aluminum, is also 30% more effective than traditional anti-fouling paints.

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.
