West System Epoxy

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

502 Black Pigment

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

Time is Everything

A last-minute ski repair

By Grant Hilger

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

Larson Thunderhawk

By Mick Ignatiuk

Built in 1957, my 15′ Larson Thunderhawk Jr. is a fiberglass runabout reborn. I launched her into the waters of Grass Lake, in Fox Lake, Illinois in late August 2010. But before this happened, the boat underwent a major restoration. I purchased this boat in August of 2009, after it sat idle for several years, collecting dirt, rainwater, leaves and snow. All that remained was its shell,

I purchased this boat in August of 2009, after it sat idle for several years, collecting dirt, rainwater, leaves and snow. All that remained was its shell, motor, and a rusted trailer. I found a group of Larsen enthusiasts who helped me locate my boat’s original specs, drawings, and
color charts.

Six10 Thickened Epoxy Adhesive

How Six10 was Formulated

By Mike Barnard

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

Getting the Most Out of G/flex®

By Julie Van Mullekom
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
