Welding Instructions

1. Always firmly support components to be  welded. Cut edges with masonry blade or saber saw so that they fit together.  Don’t forget your safety glasses. 2. Sand the surface to be welded from the  raw edge to about 1” beyond the area to be welded. For best results, feather out the material so that edges will be about one-half the thickness of the original laminate.
An inside weld should always be made on  large diameter pipes, or in any area that can be easily reached. This ensures maximum corrosion resistance. The inner overlay should consist of at least two plies of chopped strand mat with a final additional ply of surfacing mat. The initial ply width shall be a minimum of 3 inches.  Each successive ply of  reinforcement is to be 1/2” wider than the previous ply. 3. Catalyze resin in proportions according to the chart below. Then coat the raw edges to be joined using Formula B. If there are large pits or minor mismatch you can make a mixture of catalyzed resin (Formula B) and formed silica (cabosil) into a putty and use it to fill the void. Formulated putty is available from Bittner
