Techniques for Fiberglassing Overhead

By Tom Pawlak

The prospect of having to fiberglass the bottom of a hull can be a bit ominous. Any type of overhead work can be frustrating, but the thought of trying to hold fiberglass in place while applying epoxy can produce nightmares for some people. This is especially true if you will be working alone. Continue reading

Repairing Fiberglass Powerboat Transoms

By Tom Pawlak

Transoms are major structural parts of fiberglass powerboats, especially outboards. Transoms not only support the weight of the motor, they maintain the shape of the boat, they are a mounting point for holdowns, towing eyes and other accessories. And, they must be able to let water out of the hull, without letting it back in. Continue reading

Edge Gluing Fixtures

By Brian Knight

Rectangular or square edge strips tend to get out of alignment between mold stations, especially where the bend is tight and the planks have to be forced into position. You can build intermediate mold stations in these areas to support the planks in more places. Continue reading

Holding Strip Planks in Place

By Tom Pawlak

There are many ways to hold strip planks in place while the adhesive between them cures. The best method for your project depends on how you plan to finish it, what fastener equipment you have on hand, and how much holding power you need to keep the strip planks in place. Continue reading

Panel Warping

By Tom Pawlak

CAUTION: Strip planked projects can warp to the point of being unusable if one side of the wood core is fiberglassed and the other side is left unsealed. Changes in wood moisture content on the unsealed side will cause the project to change shape. The potential for warping is greatest on thin wood-strip projects like canoes and kayaks. The thinner the planking, the greater the risk. Continue reading

Big Batch Mixing Methods

By Tom Pawlak

Most of us use epoxy in small batches, mixing several ounces at once. This gets the job done 95% of the time. But for some projects, such as large laminating jobs, you may need large batches of epoxy. Before you begin, you should understand what’s involved in mixing big batches of epoxy. Continue reading

Fiberglassing – Shop Tips

By Tom Pawlak

Corners that require fiberglassing need to be rounded to allow the fiberglass cloth to conform to the corner. If the fabric you are working with won’t conform to a rounded corner, here’s a tip that may help. When draping fiberglass around a corner, orient it so the fibers are at a 45° angle to the corner. The fibers will conform much better than if oriented at 90°, because they are not bending nearly as much. Continue reading

Fiberglass Removal Techniques

By Tom Pawlak

Occasionally we receive calls from people who want to remove fiberglass cloth from wooden structures. The fiberglass on the bottom of a stripper canoe has worn out or the fiberglass and polyester on the deck of an older wooden sailboat has delaminated. The techniques described here work well for removing 1 or 2 layers of fiberglass cloth from wood surfaces. Continue reading

House Paint Primer Performance

By Tom Pawlak

In the past, we’ve recommended applying an alkyd base primer over well cured, clean, and sanded epoxy surfaces. We wanted to know how this primer compared to the newer, fast drying primers now available. We recently did a study of various house paint primers over epoxy to support the growing number of customers using WEST SYSTEM epoxy for building restoration. Continue reading
