Why can’t I apply epoxy to vertical surfaces? This is a question Gougeon Technical Advisors are asked all the time. Our response? Why, sure you can! You just need to apply it in thin coats using a foam roller. I’ll provide some tips for preventing sags or runs when coating vertical surfaces, achieving a thin coat, and choosing the best hardener for your working temperature.
Pre-finishing parts with WEST SYSTEM® Epoxy before installation is a technique that was popularized by guess who? The Gougeon brothers. It can save time and increase the quality of the finish. Coating small parts can also be a challenge, but it’s much easier if the parts are held in a way that provides good access for roller and brush coating. Continue reading
You’ve just finished your epoxy project and it looks great! But you don’t want the sun’s UV rays to start degrading the epoxy. So, like the smart individual you are, you look into applying a UV stable topcoat over the epoxy so your project will last for years to come. You look at your options, go down a few rabbit holes, and come out much later asking why is it so difficult to select a UV stable topcoat for my epoxy project? Continue reading
Need to coat something on all sides? Long ago, retired Tech Advisor Captain James R. Watson creating these handy instructions (and charming sketches) of his favorite tricks for epoxy coating on all sides of an item. Continue reading
Not that long ago, clear coating with epoxy meant that you were finishing a natural wood canoe or kayak, or the teak toe rails on your boat. Today, WEST SYSTEM 105 Resin and 207 Special Clear Hardener is used for clear coating in many different ways. Regardless of the project, there are some basic techniques to follow when epoxy coating and a few pitfalls to avoid. Continue reading
About 30 years ago, I built an 18′ wood strip canoe. At the time, my family was young and I could only work on it intermittently. Over the course of six months, I had faired my mold frames, applied the redwood strips, faired the outside of the hull with a keen eye and applied the fiberglass cloth. Two months later I decided to take it off the mold to fair and fiberglass the inside. To my horror, the exterior hull bottom had a big dimple in the middle when removed from the forms. I immediately knew the cause. The humidity in my garage had skyrocketed since the outside of the hull was finished with fiberglass and epoxy. The unsealed inside of the hull had probably gained 4-5% in moisture content since the outside was fiberglassed. Continue reading
During the fall of 2016, I took a technical call from a customer who owned a Sunfish Sailboat. He lived in the area and was looking for help repairing a few minor gel coat cracks and restoring his wooden daggerboard and rudder. I told him I would be happy to help because this would be a good opportunity to write an article about using WEST SYSTEM 105 Resin and 207 Special Clear Hardener for the wood restoration part of his project. The mahogany daggerboard and rudder had weathered over the years because of only being varnished. Continue reading
This article is Lesson 4 of a series. See bottom of page for links to additional articles in this series.—Ed.
The way a finish ages has everything to do with the way it is anchored to the wood. Sealers and primers are often taken for granted; we simply read the can and follow directions. There are so many reasons for using a sealer and many methods for applying them. Let’s look at what we learned while sealing Sparks, the electric launch I built. Continue reading
WEST SYSTEM® epoxy has long been a popular choice for clear coating table tops. It works great as a buildup coat and a moisture barrier. It also showcases the beauty of wood grain and fiber weaves. Formulated with boat building in mind, WEST SYSTEM epoxy is not intended as a final finish coating. You may find it a bit more difficult to achieve a perfect surface with epoxy than with a coating formulated specifically for final finishing, such as varnish.
However, WEST SYSTEM offers some distinct advantages. It builds up quickly: a single coat of 105 Epoxy Resin® with 207 Special Clear Hardener® offers about four times the thickness of a typical coat of polyurethane varnish. WEST SYSTEM epoxy is also an excellent moisture barrier, stabilizing the surface so your final finish coat will look beautiful longer. Continue reading

When you’ve completed a coating task using a 801 Roller Frame and 800 Roller Cover, what next? The roller frame is reusable. But if you leave it resting in the pan while the residual epoxy cures, you‘ll probably ruin both the reusable pan and the roller frame. If you lay the roller and frame on a work bench, it will be stuck there the next day.
Setting the roller on a piece of plastic will bring you closer to success but in any instance where the roller frame rests on a surface while the epoxy cures, the cover will accumulate Continue reading
