The Basics of WEST SYSTEM Epoxy

By Don Gutzmer

For those who want to work with epoxy resin and hardener, each February Gougeon Brothers provides a Fiberglass Boat Repair Class for repair professionals. Here are some of the basic techniques we teach in the class, as well as helpful tips for working with WEST SYSTEM Epoxy.

Epoxy’s Cure Stages

What is the difference between working time, pot life and cure time? All three are slightly different. Continue reading

Epoxy casting can be done in many colors and depths

Casting Epoxy

By Rachael Geerts

Casting epoxy is really catching on. Live edge tables with bright centers, clear coasters with stones, wood, or shells intricately placed, or even beautiful jewelry can be made with WEST SYSTEM Epoxy. With so many people venturing into using epoxy this way, I will address common questions about casting depth, colorants, bubble removal, and finishing. Continue reading

WEST SYSTEM 300 Mini Pumps

300 Mini Pumps

To buy or not to buy?

By Terry Monville

Do I really need the Mini Pumps?

If it’s a two-part epoxy, why are there three pumps in the package?

The pumps look the wrong size to fit my cans. Are you sure these are the right ones?

Selling WEST SYSTEM Epoxy in a retail environment for more than 20 years, those were the three most common questions I received.

These are valid questions. We’ve all been in a situation where the salesperson is trying to upsell us or has no clue what we really need. In the case of Mini Pumps, however, the salesperson is trying to do you a favor.

That’s a Fact!

Useful information about WEST SYSTEM Epoxy

By Mike Barnard

Using gelcoat over WEST SYSTEM

It’s a myth that if you plan to gel coat over a repair, you must make the repair with polyester. We’ve used gel coat over epoxy for decades, shown it in our instructional videos on repairing fiberglass boats, and discussed it in past issues of Epoxyworks. Continue reading

502 Black Pigment

502 Black Pigment

by Mike Barnard

On January 1, 2015, we began selling a new WEST SYSTEM Epoxy pigment. We already had the 501 White Pigment and the 503 Gray Pigment, so it seemed right to introduce our new 502 Black Pigment. Just like the 501 and the 503, it alters the color of the epoxy mixture without affecting the cured physical properties. Similarly, the maximum acceptable loading is 3%. This is great for hiding a surface with a single coat of black epoxy. Adding more pigment will increase the opacity, but can skew the mix ratio because there is epoxy resin in the pigment.

G/5 Five-minute Epoxy, A Versatile Glue

By Tom Pawlak

G/5 Five-Minute Adhesive is a fast curing two-part epoxy that allows 3-5 minutes of working time. It has an ideal viscosity which allows it to penetrate porous surfaces yet is viscous enough to bridge gaps when gluing broken objects. It adheres to a number of surfaces including wood, ceramic, metal, leather, plaster, stone, fiberglass, glass, cork, some plastics and paper. G/5 is an excellent choice for quick repairs around the house, high-end crafts and much more. Continue reading

Flying Dutchman Restoration

By Douglas Heckrotte

Surcease is a late ’50s International Flying Dutchman Class sailboat. The Mahogany hull was cold-molded in Holland and imported by Paul Rimoldi of Miami Florida. Mr Rimoldi made everything else, including many pieces of hardware. He raced the boat on Biscayne Bay into the ’60s and sailed it for many years. He rebuilt the boat in the late ’80s but died before he finished. We bought the boat in August 1992 from his widow and sailed it for almost a season before we discovered that the hull was in very poor condition; the Urea-resin glue between the veneers had begun to turn to dust. We stored the boat and bought another Flying Dutchman.  Continue reading

Small Projects and Repairs

By Jeff Wright

Many of our EPOXYWORKS articles feature projects that our customers have spent years building and represent major personal accomplishments. I also believe we have many customers who, like me, use WEST SYSTEM Epoxy simply to keep an older boat in good repair.

The following are examples of repairs and small projects that I have completed on my personal boat over the last ten years. These would apply to many production fiberglass boats. Since WEST SYSTEM Epoxy has a shelf life measured in years, it is easy to keep it on your shelf and tackle these tasks when it’s convenient. Continue reading

Smaller Can Be Better

Tips for mixing small batches of epoxy

By Tom Pawlak

My favorite way to mix small batches of WEST SYSTEM® Epoxy, when less than full pump strokes on the mini pumps are required, is by metering resin and hardener into a graduated cylinder made with a plastic syringe. The 807 Plastic Syringes, in our product line, can be modified for this by cutting off the end of the syringe body so it looks like the end of a clear piece of plastic tubing.

For the 5:1 mix ratio needed for 105 Resin and 205 Fast Hardener or 206 Slow Hardener, you’ll need to measure ¼” back from the cut off end of the syringe body and make an Continue reading
