Adding 5% laquer thinner results in a 60% reduction in viscosity. It can also reduce epoxy's compressive strength by up to 35% if the solvent becomes trapped. To avoid this problem, you should allow plenty of time, generally overnight, for the solvent to evaporate out of the epoxy before filling, bonding or coating over it. There is a better solution to get good penetration without losing strength or moisture resistance. installation method for wood plastic composite fenceWe recommend moderate heating of the repair area with a heat gun or heat lamp (to about 115��F��still comfortable to touch). The epoxy will have a lower viscosity and penetrate more deeply when it is warmed by contact with the warmed wood cavities and pores. In addition, heat will expand air in the wood pores causing it to out-gas.

When the heat is the removed, the cooling wood will draw epoxy back in. Slower hardeners (206, 207, 209) will have a longer working life and should penetrate more than 205 Hardener before they begin to gel. When the epoxy cures it will retain all of its strength and effectiveness as a moisture barrier, which we feel more than offsets any advantages gained by adding solvents to the epoxy. In addition, you can continue with the repair, rather than waiting overnight for the solvents to escape, before filling, bonding to or coating over the thinned epoxy. For more detailed information on thinning epoxy refer to Gougeon publication 000-800 Thinning West System Epoxy. 3.3 Reinforcing Tensile strength can be added to a dry rot repair area advantage panel with decorative openingby using synthetic fiber such as fiberglass, carbon fiber or Kevlar? in appropriate amounts with epoxy. Refer to Section 8.4.5 for application information. Apply the reinforcing after the dry rot has been excavated and filled, or drilled and filled. Stainless steel threaded rod has also been used to reinforce and join pieces with excellent results. The rod can be bonded into drilled or grooved pieces as a structural pin to tie individual or separate pieces together. See Section 6.4 for information on bonding threaded rod.

Replace or reinforce in place framework that is too weak to carry its designed load. Structural framework includes the keel, stems, hull frames, floors, stringers, deck beams, sheer clamps, shelves, knees, carlins or thwarts. They vary widely in size, shape and position, but have many problems and repair techniques in common. Frames can be damaged from dry rot or from impact. Under impact, frames often break in multiples. wood composite decking stainIf you find a cracked frame, take the time to look for others, especially adjacent to the broken one. Hull frames often break at stringer edges, the turn of the bilge and at the reverse turn (especially in the stern). Examine the outside of the hull for a knuckle or unfair spot in the planking in the area where the frames are damaged. If you find planks that are out of position, temporarily force the affected planks (and frames) back using whatever means are available.
