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.
I’m fast approaching my 22nd year of working here at Gougeon Brothers, Inc. From my first day on the job, I have lived the controversy surrounding penetrating epoxies vs. high-solids epoxies in general and WEST SYSTEM® Epoxy in particular. I have met with the formulator and founder of a popular brand of penetrating epoxy and talked to him many times over the years. He is a nice fellow and passionate about his product, but in the end we had to agree to disagree. Continue reading →
Building with epoxy fillets is especially beneficial when attaching bulkheads to hull sides, attaching hull sides to hull bottoms where the faces of the plywood are coming together at ever-changing angles. Gluing plywood structures together with epoxy fillets saves considerable time constructing the joints and reduces the overall weight of the structure compared to more traditional methods using wooden cleats and screws. The strength and gap-filling qualities of epoxy eliminate the need for precisely fitted wood cleats that otherwise require time and skill to create. When gluing with conventional adhesives, that are non-gap filling such as resorcinol glue, wood cleats need to be well fitted, need to be wide enough to provide sufficient glued surface area, and provide enough thickness for screws to be driven into.

(GBI) we have spent long hours writing manuals and training people to use proper techniques using epoxy to keep wood dry and strong. Continue reading →
