How to use...
PC-Products Paste Epoxies - PC-7, PC-11, PC-Super Epoxy
Directions for use:
Using separate knives remove the amount of paste epoxy needed. Mix equal parts A and B on a flat clean surface until a uniform color is achieved. Surfaces to be bonded must be free of dirt, oil, rust, ect. Denatured alcohol can be used to prep the surface. For best results, rough up the surface to be bonded. Normally, no vice or clamp needed. Prop or tape heavy objects to a wall or ceiling.
Apply the paste epoxy in any thickness to both sides of surface and bring together firmly. Be careful to insure that ample amount of the paste epoxy remains between the contact surfaces. Use screen wire or fibreglass cloth to reinforce large voids and gaps.
Mixing tips:
In cold or cool temperatures, place the paste epoxy container near heat prior to using. Paste epoxy mixes and spreads easier at 80°F than at 40°F. Any clean smooth flat surface is an excellent surface for mixing and working. A small putty knife or flexible artist spatula are great tools for mixing and applying paste epoxy. Denatured alcohol is excellent for smoothing applied paste epoxy. Also use Denatured alcohol to clean surfaces before applying.
Note: Most epoxies are temperature sensitive and will cure faster at higher temperatures and slower at cooler temperatures. Speed cure with artificial heat.
After cure:
You can paint drill, machine, sand, file, tap, or saw.
