Polyester or Epoxy Resin? The Right Choice for Repair

The difference between polyester and epoxy resin in fibreglass repair: adhesion, durability, waterproofing and cost.

The quality of a fibreglass repair largely depends on choosing the right resin. There are two main options: polyester and epoxy. Each has its place.

Polyester resin

Most boats are built with polyester; it's compatible and economical in repair. Pros: low cost, easy to apply, compatible with the original laminate. Limit: lower adhesion and waterproofing than epoxy.

Epoxy resin

Pros: superior adhesion, high strength and excellent waterproofing. Preferred for the osmosis barrier coat and structural repairs. Limit: more expensive and more sensitive to application conditions.

Which and when?

For general cosmetic repairs compatible with the original laminate, polyester; for underwater, structural and osmosis work, epoxy. We make the right choice for the construction and the job.
