5. Clean up excess epoxy. Use a sharpened mixing stick to scrape up excess epoxy before it cures. Station a helper inside the boat or check the inside frequently to clean any epoxy leaking through the planking. 6. After the epoxy cures thoroughly, remove the excess portion of the spline with a plane followed by coarse sandpaper (Figure 5-5). Fill the vertical seams and any remaining voids with epoxy/407 fairing compound before final fairing and finishing. 7. Important! Coat the exterior following the procedures in Section basement floor board Australia7. Failure to apply an epoxy moisture barrier may cause structural damage when planks swell. Fiberglass cloth is often applied to provide additional reinforcing and abrasion resistance. 5.1.3 Filling the seams with epoxy. A quicker but more expensive way of bonding the seams is to fill the entire gap with thickened epoxy (epoxy is more expensive than wood by volume). This method is more practical on seams that are too curved or tight for a spline. 1. Open the seam as before. The gaps do not have to be a particular width, as long as you expose fresh wood on each plank edge. 2. Wet out the gap with resin/hardener mixture.

3. Fill the seam with thickened epoxy/403 (mayonnaise consistency). (Note: 403 filler will leave an off-white colored seam, which will not matter if you plan to paint the surface. If you plan a clear finish you may want to use 405 Filleting Blend or a coloring agent mixed with the epoxy to match the planking color. See Section 7 for information on finishing.) Large syringes or caulking tubes are convenient to inject the thickened epoxy into the seams. Smooth the mixture flush with the surface and remove excess epoxy before it cures. Check the inside for leaks and clean any excess epoxy before it cures. 4. Sand the surface fair after the epoxy cures thoroughly. Fill any remaining low areas with epoxy/low-density filler mixture. buy from factory wpc fencing5. Coat the exterior following the procedures in Section 7. 5.1.4 Repairing damaged planks in place If you will be repairing or replacing a lot of planks, it is best to repair individual planks and small areas completely before going on to other areas. The hull may be seriously weakened and lose its shape if you remove too many planks at one time. Scarf joints or butt joints can be used in repairing damaged sections of planks without removing the entire plank.

Support the hull in its proper shape before bonding. Scarf joint method To repair damaged sections of planks using scarf joints: 1. Remove the damaged part of the plank using a circular saw, hand saw or chisel. 2. Bevel each end of the plank opening with an 8-to-1 scarf. 3. Cut a piece of wood to fit the opening. Match the 8-to-1 bevel on each end (Figure 5-6). Make the new piece of wood slightly thicker than the original planking. Excess material inside or outside the hull can be planed off after the glue has cured. important of wood plastic composites for the world4. Wet out the mating surfaces with resin/hardener mixture. Re-coat the scarfed surfaces as necessary until the end grain is fully saturated. Repairing Hull and Deck Planking 30 5 5. Apply thickened epoxy/403 or 406 (peanut butter consistency) to one side of each bonding area.
