Prepare your surface as best you can to ensure the best possible bond with PC-Marine™. Remove contaminants such as dust, dirt, oil, barnacles 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. 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’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.

For outside repairs, be mindful of the temperature before starting. It is not recommended to use PC-Marine™ below 2°c.



PC-Marine™ has a work time of 20 minutes 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-Marine™ sticks to PC-Marine™. It can be applied thick or thin, it cures from within via a chemical reaction.

PC-Marine™ has a consistency similar to Plasticine.

PC-Marine™ 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 green colour disappears. When properly mixed the epoxy will all be one consistent colour.

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

Underwater & wet use

Underwater & wet use

Dry repairs are always preferable but it is possible to apply PC-Marine™ underwater. Before applying, brush clean the surface.



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-Marine™ 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-Marine™ has fully cured it can be sawed, sanded, tapped, drilled, machined, filed and painted. Most repairs made with PC-Marine™ can be returned to service after 60 minutes. Some applications may require a full 24 hour cure.

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