Prepare your surface as best you can to ensure the best possible bond with PC-Woody®. Remove loose paint, wood fibres and debris with a stiff brush, sandpaper or scraper. Remove contaminants such as dust, dirt, oil and grime with a solvent such as methylated spirit, acetone, rubbing alcohol (isopropyl alcohol) or lacquer thinner.

Wood that has been damaged by rot or infestations should be treated with a wood hardener such as PC-Petrifier® or PC-Rot Terminator®.

For outside repairs, be mindful of the temperature. In temperatures below 10°c the curing time will increase and you may wish to use a heat source such as a heat lamp to accelerate the curing. Heat guns and hair dryers should be used with caution because they can be too intense. We do not recommend applying PC-Woody® at temperatures at or below freezing (curing will pause, resuming as temperatures improve).



PC-Woody® contains real wood and can be tinted and stained, tinting being the most effective of the two.

Tinting: Tinting with colourant or dry pigments is effective. It can be difficult to match colours with pigments or universal colour dispersions. Darker tinting is less obvious than lighter. You could use the sediment of a settled stain to tint PC-Woody® but dry pigments would be preferable.

Staining: PC-Woody® can be stained after sanding. The results will vary depending on the stain. Lighter colour stains are ineffective. Use stains containing greater pigment. Stains that contain only dye will produce disappointing results.



PC-Woody® has a work time of 30-40 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-Woody® sticks to PC-Woody®.

To mix PC-Woody® you’ll need a spatula, putty knife or similar (something stiff) and probably a piece of scrap wood, cardboard or similar to mix on. We don’t recommend mixing in a cup or container as it can be hard to judge the % of parts and will accelerate the reaction. PC-Woody® that is spread out will have a longer worktime than in a container. If the repair is outside and the weather is cool we’d recommend placing the tubs somewhere warm to reduce the viscosity.

PC-Woody® should be mixed in equal parts, one part A (white) to one part B (brown). Off-ratio measurement is the main cause of soft cured PC-Woody®. The amounts should be as close to equal as possible, but a slight excess of part A is preferable to an excess of part B. Excess of part B (the hardener) will not accelerate curing and may prevent it from hardening. We generally recommend eyeballing the amounts but if more precise measurements are desired, based on an average net weight it is 10.6 parts A to 10 parts B.

Eyeballing tip: Make a circular mound (like half a golf ball) of part A. Alongside but not touching, make a rounded mound of the same circumference, adding or taking away until the height matches the mound of part A.

When properly mixed the epoxy will all be one consistent colour.

Remember to use a different spatula/tool in each tub or wipe it off with methylated spirit on a cloth/kitchen roll in between! This will ensure that the rest of the tubs remain good and uncured for future use. Store in a cool location.



After using PC-Woody® clean up using methylated spirit, acetone, rubbing alcohol (isopropyl alcohol) or lacquer thinner to clean tools and mixing surfaces before PC-Woody® 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-Woody® has fully cured it can be sanded, carved and can take screws and nails. We recommend allowing 12 hours to cure at 20°c (longer at cooler temperatures). It should reach full hardness in 24 hours. See the Prep section for more information on curing in cool temperatures.

Sanding: 80 grit sandpaper works well on PC-Woody®. Fine sandpaper such as 120, 150 and 180 can also be used. Mechanical sanders work best after 48 hours. Wear a respirator and ventilate mechanically.

Turning: PC-Woody® can be turned on a lathe but it will do so differently than wood. Wear a respirator and ventilate mechanically.

Fixings: It is best to drill a pilot hole before using screws and nails.

We recommend applying a stain-sealing primer/sealer to the repair before painting. A primer/sealer is essential if you are applying gel coat.
