3. Kraft paper to protect floor or work table while prewetting glass.
4. Paper or plastic mixing cups.
5. Paper or plastic mil/cc graduated cups for measuring catalyst.
6. Wooden stick for mixing resin.
7. Sanding equipment for abrading pipe or damaged area that has to be replaced (16 grit disks preferable).
8. Circular saw with a masonry blade or saber saw for cutting FRP.

Safety Tips to Remember

1. Do your welding or patching in ventilated areas protected from inclement weather. Under no circumstances should smoking or an open flame be permitted in the area where the work is being done.
2. Safety glasses should be worn, especially during sanding.
3. Hands and all tools should be cleaned immediately upon completion of work.
4. Discard excess catalyzed resin immediately after use. You can store unmixed resin and catalyst in tightly-covered containers that are kept away form excessive heat.
