Gelcote International - Fiberglass Resin with Wax 1 Litre

Gelcote International Fiberglass Resin with Wax is a polyester liquid resin formulated for both marine and automotive fibreglass applications. It comes packaged with hardener so you have everything you need to mix and apply the resin right out of the box. The wax additive in the resin rises to the surface during curing, sealing out air and allowing the resin to cure tack-free — an essential property when applying final coats to fibreglass repairs.

Ideal for Final Coat Applications

This resin is specifically intended for use as a final coat in fibreglass layup and repair work. The wax content ensures the surface cures completely without remaining sticky, which means you can sand, fair, or paint over the cured resin without additional preparation steps to address uncured surfaces. For Canadian boaters tackling spring commissioning repairs or end-of-season maintenance, this product streamlines the finishing process.

How to Use Fiberglass Resin with Wax

Using this resin is straightforward. Mix the polyester liquid resin with the included hardener according to the manufacturer's directions, then apply it over your fibreglass cloth or mat layup as the final sealing coat. The wax in the formulation migrates to the surface during cure, creating an air barrier that promotes a full, tack-free cure. Keep in mind that waxed resins should only be used for the final coat — if you plan to add additional layers of fibreglass, use a non-waxed resin for the intermediate layers to ensure proper interlaminar adhesion.
