Step 2 Protect
Before you protect
Before you begin, note the hazards and precautions on this website and the can labelling, and ensure that you use the correct safety equipment as detailed in the Safety Data Sheet.
Once applied, CUTEK® Extreme generally requires 3-5 days of dry conditions after coating to facilitate full penetration/diffusion and an even color finish; so check your weather forecast before coating.
Clear, un-tinted CUTEK® Extreme will allow your wood to naturally lighten/silver/gray when exposed to sunlight while retaining its protection characteristics. Unless you want a clear finish that will naturally lighten/silver/gray off in a few months, it is important to mix in a CUTEK® Colortone to your can of oil before use. Adding a CUTEK® Colortone provides UV color protection and slows the lightening/silvering process.
To choose which Colortone suits your wood and project, visit our Colortone page.
Note: CUTEK® Extreme diffuses deeply into your wood and will continue to provide moisture protection and improve dimensional stability even if a CUTEK® Colortone is not added and your wood becomes weathered and grayed.
After preparing your wood, it will need to be completely dry prior to coating with CUTEK® Extreme. It is very important that your wood is clean, non-greasy and dry with a moisture content of less than 17%. It is also very important that the surface of the wood is free from chemical residues and is not exposed to environmental contaminants such as dusts while the CUTEK® is drying.
Stir the CUTEK® Extreme oil thoroughly (with the added CUTEK® Colortone if desired) before and during use. Make sure you stir from the bottom of the can to ensure active ingredients are properly mixed throughout the oil.
Apply thin, even coats with a brush, or paint pad applicator. CUTEK®’s Professional Finish Deck Brush is a good option. CUTEK® Extreme works best when applied as a THIN COAT – two or three thin coats on finished wood and hardwoods are much better than one or two thick coats. For best results, ONE coat of CUTEK® Extreme should be applied to all faces of the wood prior to installing, with a SECOND coat applied to the top surface once the first coat has completely penetrated/diffused (dried).
If applying post-construction, apply two thin coats to all accessible wood surfaces, ensuring the first coat has completely penetrated/diffused (dried) before applying the second coat.
Unlike traditional wood coatings, CUTEK® Extreme needs to penetrate/diffuse deeply into your wood. After coating, CUTEK® Extreme will slowly migrate into your wood to repel moisture, improve dimensional stability and lengthen the service life of your wood. This penetration/diffusion process varies in time for many reasons including differences in wood type (species, density, porosity, age of wood and residual moisture content) as well as environmental factors (temperature, humidity, weather).
Sometimes this drying process can take several days to complete. You will know when your wood is ready for an additional coat of CUTEK® Extreme when it is completely dry and non-greasy. To test: press a tissue or rag on the wood and if there is no transfer it is dry. Please note the second coat of CUTEK® Extreme will take longer to migrate into your wood than the first coat.
Equipment (including brushes) may be cleaned with CUTEK® Quickclean, mineral spirits or soap and water. If not correctly cleaned or disposed of, oily rags and other oily materials may cause combustion fires. After use you MUST immediately spread out all oily material outside to dry, by flattening them out to their full size in an airy spot at temperatures above 39ºF or wash them thoroughly with water and detergent and rinse. Remove all oil from all clothes, tools, rags and any other materials contacted during use or as a result of an accidental spill. Ensure wash water is disposed in accordance with local regulations.
