PC-11® thrives in wet environments. It is resistant to water whether it is fresh or salt. Thick consistency like PC-7® and long open time (30 min). Work horizontal or vertical, indoor or outdoor. Wet, dry or under water. Whether you are working on an area where you just can’t remove water and moisture or you want the white color for your repair, PC-11® is your choice. Choose PC-11® for ceramic repairs, pools and spas, fiberglass boats, tubs and sinks, stock tanks and thousands of other repairs. It has excellent adhesive properties bonding metals, fiberglass, wood, tile and some plastics such as ABS and rigid PVC. Ample open time allows tooling or positioning in order to tackle larger and challenging jobs. When mixed, the epoxy, part A (white) and the hardener part B (lt. blue) react to form a bond of tremendous strength and flexibility. The PC-11® formulation is slow curing, but slow can be a good thing especially for large tasks.

Working Time: 30 Minutes

Cure Time: 24 Hours (48 Hours for full cure)

PC-11® is thick. Thick is good if you need to work vertically or want to hold an object in place. How thick? Not quite as thick as peanut butter.

When mixing equal parts “A” and “B” we generally recommend eyeballing the amounts but if more precise measurements are desired, based on an average net weight for each size unit we have:

PC-11  107 grams A to 100 grams B

How to prepare a surface for bonding with PC-11® Epoxy Paste

Remove contaminants such as dust, dirt, oil, barnacles and grime with a solvent such as Denatured Alcohol, Acetone, Rubbing Alcohol (isopropyl alcohol) or Lacquer Thinner. Mild detergent solution in water is also good removing contaminants. Use a clean paper towel or rag for wiping. Do not use Mineral Spirits or Paint Thinner for removing contaminants. For a wet or underwater surface; clean contaminants as best as you can. Solvents will not help you in this situation.

Remove rust and loose paint with sandpaper or wire brush. Epoxy typically sticks to most paints. If there is a concern of the paint’s adhesion then remove it with sandpaper or wire brush.

Smooth, glossy and shiny surfaces should be roughened using sandpaper to increase adhesion.

How to clean-up after PC-11® Epoxy Paste application

Use Denatured Alcohol, Acetone, Rubbing Alcohol (isopropyl alcohol) or Lacquer Thinner to clean tools and mixing surface before PC-11® cures.

Clean hands and skin with soap and water.

Cured epoxy can be removed by applying Paint Remover or Paint Stripper to soften the epoxy surface. Scratch off the softened epoxy. Repeat as needed.
