Product Details

Interlux Watertite Epoxy Filler YAV135 is a two-part, easy to use, fast drying epoxy compound for filling holes and repairing scratches in gelcoat and fiberglass. Watertite YAV135 is strongly recommended for filling gelcoat blisters below the waterline and for use with the Interprotect Epoxy Barrier System.

Info & Guides

Interlux Watertite YAV135 is an excellent fairing compound due to its unique two-phase cure, which gives a long easy-to-sand window. Watertite can be applied to a thickness of 3/4" without sagging and its superior spreadability makes it an ideal glazing compound for filling small nicks and scratches.

What is Gelcoat Blistering?

Osmosis is caused by a chemical reaction between water and unreacted substances remaining in the manufactured hull. Water breaches the exterior gelcoat and reacts with the chemical components creating acidic substances. These substances create pressure behind the gelcoat which causes blisters and eventually cracking. Once the gelcoat is breached in this manner, the underlying laminate is capable of absorbing water like a sponge.

Use the Interlux Interprotect system to treat and help prevent this insidious problem.

A: Hey Padre, Thank you for reaching out. You can use it direct or over the primer, either way. Sometimes priming first can help with seeing imperfections.

Q: null Do I need to use an epoxy resin first to seal any exposed fiberglass and can I embed new fiberglass mat with this product?

6 years ago

6 Answers

A: This product is just a filler, if you need to do structural or fiberglass repairs, use the appropriate epoxy system and cloth for the task. Glass matt is not necessarily the right fiberglass material to use for epoxy as it does not have styrene to break down the binder and wet out as easily.
