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 →
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 →
The evening of March 19, 2013 I inspected my 217cm Atomic™ downhill race skis in preparation for race day. Because of the early ending to winter in 2012, these skis have not seen the light of day in almost two years. The only real chance I get to ski with them is at the annual Boyne Highlands Downhill Race in Harbor Springs, Michigan. This late March tradition is usually the grand finale of Michigan’s ski racing season. This year the weather was shaping up perfectly for outstanding conditions, and I was chomping at the bit to ski fast! Much to my surprise, when I picked up one ski I found that a section near the tail was delaminating. On the inside edge of the left Continue reading →
Putting epoxy resin and hardener into a single cartridge was an idea we had years ago, but the technology was never around to do it. Once the technology became available (in the form of a u-TAH chambered cartridge with a mixing wand), we needed to develop a two-part epoxy to go in it.
We chose the characteristics we wanted for this new epoxy: long open time, fast through-cure, full cure overnight, and ability to cure at low temperatures. With these Continue reading →

Are you the kind of person who just can’t get enough of a good thing? Looking for a better way to squeeze out that last little bit of G/flex adhesive from your tube rather than resorting to pliers, a vise or maybe even Grandma’s rolling pin? Maybe you’d like to get a fatter bead of adhesive or your tube is a bit clogged. Boy do we have the some easy and inexpensive tricks for you! Continue reading →
While WEST SYSTEM® epoxy has a long shelf life, age will eventually affect its handling characteristics and cured strength. When stored for very long periods, hardeners may turn darker (reddish to purple), become thicker and give off more odor. 105 Resin may lose some clarity and also become slightly thicker. Use extra care when mixing age-thickened products (stir extra thoroughly), and if color and/or clarity are crucial to your project, buy some fresh resin and hardener for best results. 207 Special Clear Hardener is specially formulated for clarity and flow.

In this article I’ll describe our standards for testing epoxy and how we test epoxy to determine its handling characteristics and cured physical properties.
Testing Standards These are the standards we follow no matter which epoxy we are characterizing.
Two-week room temperature cure After proper metering and thorough mixing epoxy will continue to cure after it has solidified, until all amines have paired up. Over years of testing we have found that two weeks of curing at room temperature, which we define as 72°F (22°C), is a good indication of its full strength.Continue reading →
New for 2012, WEST SYSTEM is offering three specialized boat repair kits designed with the do-it-yourselfer in mind. Each contains the right materials and instructions for making lasting repairs and retails for around $30 at your local stocking WEST SYSTEM dealer. Continue reading →

WEST SYSTEM®, Chesapeake Light Craft (CLC) and nine family groups joined forces at the 2010 WoodenBoat Show at Mystic Seaport in Connecticut this June to build nine Sassafras 16 kit canoes. With only a blue and white striped rental tent to shield them from the unseasonably hot weather in Mystic that weekend, everyone labored hard to get their boats a long way toward completion in just three short days.

Spot prime metals with G/5 in place of slower drying paint primers for indoor applications prior to applying latex paints. Latex paint can be applied to G/5 about ten minutes after the epoxy is applied and while the epoxy is still soft. G/5 provides a thin barrier and prevents rust that otherwise forms in latex paint when it dries over bare steel.
Model railroad set builders create natural looking surfaces by applying a film of G/5 adhesive and then sprinkling small objects onto the surface while it is still uncured. These Continue reading →
