Prepare your surface as best you can to ensure the best possible bond with PC-Plumbing™. Remove contaminants such as dust, dirt, oil and grime with a solvent such as methylated spirit, acetone, rubbing alcohol (isopropyl alcohol) or lacquer thinner. Mild detergent solution in water is also good for removing contaminants.

Do not use white spirit or paint thinner for removing contaminants.

Remove rust and loose paint with sandpaper or wire brush. Epoxy typically sticks to most paints. If there’s 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.

Adhesion to wet or damp surfaces can be improved by wiping with alcohol.



PC-Plumbing™ is very fast curing so only mix as much product as you think you can apply in this time. You will be able to apply more to continue filling across an area, PC-Plumbing™ sticks to PC-Plumbing™. It can be applied thick or thin, it cures from within via a chemical reaction.

PC-Plumbing™ has a consistency similar to Plasticine.

PC-Plumbing™ should be mixed by hand and we recommend wearing disposable gloves to minimise contact with skin.

Using a knife, slice the required amount of epoxy from the stick. Press and roll the putty with your fingers until the colour is uniform. Due to the fast cure time it is best to mix small amounts, for no more than 45-60 seconds, then applying immediately. Mixing for too long may affect adhesion if the work-time is near completion.

Unmixed epoxy can be stored in its tube for use another time. Store in a cool location.

Wet use

Wet use

PC-Plumbing™ does work in wet conditions but dry conditions are preferred.

After PC-Plumbing™ is mixed and applied it is soft and pliable for a short time. A drip is a small volume of water but has enough pressure to push the PC-Plumbing™ out of the way before it has hardened. Even a drip caused by standing water can have enough pressure to cause leakage before it cures.



To clean any tools or mixing surfaces use methylated spirit, acetone, rubbing alcohol (isopropyl alcohol) or lacquer thinner to clean tools and mixing surfaces before PC-Plumbing™ 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.



After PC-Plumbing™ has fully cured it can be sanded and painted. Within 3-5 minutes PC- PC-Plumbing™ will be very hard, reaching full hardness in 60 minutes.

We recommend applying a stain-sealing primer/sealer to the repair before painting.
