Prepare your surface as best you can to ensure the best possible bond with PC-Petrifier®. Remove loose paint, wood fibres and debris with a stiff brush, sandpaper or scraper.

Wood should be fully dry. Wet or damp wood treated with wood preservatives will decrease PC-Petrifier’s® ability to soak in. PC-Petrifier® does not displace water from inside damp wood. Ventilate the wet wood using a fan and if necessary safely warm with an infrared heat lamp to speed drying.

Painted surfaces must be drilled or sanded to expose the damaged wood.

Vertical surfaces should be drilled on a downward angle (45 degree) with 1/8 to ¼ inch bit to access the wood grain.

If the project is outside please be mindful of the weather forecast. More information in ‘finishing’.



Simply flip the nozzle top on the bottle lid and apply the liquid to the damaged area. You may like to use a paintbrush to help work the liquid into any awkward areas or prevent excessive dripping on a vertical surface.

Two treatments of PC-Petrifier® will achieve the best results – the first will penetrate deeply into the wood and the second will remain at the surface to make it harder.



Clean up PC-Petrifier® with paper towels before it dries and/or cures. Water is best to clean brushes, spills or drips. Cured PC-Petrifier® can be removed with citrus based solvents/cleaners. Apply solvent to loosen, then rub with a paper towel or scrape away. Paint stripper will remove cured PC-Petrifier®.



PC-Petrifier® has a water base that must fully evaporate. Do not allow the treated wood to be exposed to rain until the second treatment has fully dried. If necessary, tarp or plastic can be used to cover the area.
