Epoxy and Polyester Resin for Wood, Alloys and Composites
Shop epoxy and polyester resins for sheathing, laminating, filling, and bonding. Browse our resins, fillers and fibreglass range by category:
- Epoxy resin and hardeners
- Polyester resin and gelcoat
- Powder additives
- Fibreglass
- Epoxying accessories
- Epoxy resins offer greater strength for bonding materials, protective coatings, and structurally significant repairs. Mix them with glass fibre filler or powder additives — high-density fillers for adhesive and gap filling, low-density fillers for fairing and coving. Shop popular brands including West System, International, and Norski.
- Polyester resins offer a low-cost alternative for fibreglass laminate and cosmetic repairs. Combine them with fibreglass cloth to restore shape and surface integrity. Find polyester resins, gelcoats, and complete fibreglass repair kits from Norski, MagicEzy, and ADOS.
Epoxy resin products can be used above and below the waterline and, once sanded, offer an excellent finish for painting. Polyester resins are commonly used above the waterline and for fibreglass laminate repairs. Resins require a hardener or catalyst for curing.
Fillers, Additives and Fibreglass for Marine Applications
Combine resins with International and West System fillers and powder additives to achieve various densities and surface finishes. Low-density fillers allow easy sanding and are suitable for fairing and coving, while tough, high-density fillers offer strong adhesive and excellent gap-filling qualities.
Shop fibreglass cloth rolls in weights from 100g to 450g per linear metre. Lighter cloths use less resin and are suitable for repairs where weight matters. Heavier cloths are better for high-load areas or concealed structural work. Popular cloths sold per metre include:
- Fibreglass Cloth 100g 3oz (per metre)
- Fibreglass Cloth 200g 6oz (per metre)
- Fibreglass Cloth 290g 10oz (per metre)
- Fibreglass Chop Strand Mat 450g (per metre)
Epoxy Mixing and Application Accessories
Find the tools you need for easy epoxy work in our epoxying accessories range:
- West System Syringes
- West System Mini Pumps
- HT9000 3:1 Dispensing Pumps
- Resin Spreader
- Epoxy Pigment Paste
- West System 804 Mix Sticks (Pkt 8)
Use syringes and dispensing pumps to measure resin and hardener accurately, a resin spreader for a smooth finish, and pigment paste to tint repairs. Epoxy solvents from the accessories range help clean uncured epoxy from tools.

Frequently Asked Questions
Can marine filler be used on fibreglass, timber, and steel boats?
Yes, you can use resin fillers for repairing most boat materials. Polyester resins are best suited for fibreglass repairs, while epoxy resins can handle wood, fibreglass, aluminium, steel, alloys, and composites. Check product pages for material compatibility.
How long does marine filler take to cure before sanding or painting?
Curing can take anywhere from 30 minutes to 72 hours, depending on resin type, hardener speed, temperature, and mix ratio. Warmer conditions generally speed up curing. Need a quick fix? Look for ultra-fast or rapid resin products that can set in just five minutes.
How much resin or filler do I need for my repair?
The amount of resin and filler you need depends on surface area and required thickness. Check manufacturer guidelines to learn more about resin ratios and intended use.
Is epoxy filler compatible with antifoul paint?
Yes, epoxy is a good base for antifoul paint and is commonly used for below-waterline repairs. Make sure the epoxy is fully cured and properly sanded before applying antifoul, and check the paint manufacturer's guidelines for recommended primers or tie coats.
What safety precautions should I take when using marine fillers and resins?
Always work in a well-ventilated area and wear gloves, safety glasses, and a respirator when mixing or sanding resins. Dispose of waste resin and mixing containers according to your local hazardous waste guidelines. Full safety information is available on the product's safety data sheet (SDS).
