APPLICATION: RAW WOOD

1. With optional Hard Wax Oil Hardener, mix GF Hardener 10% by volume with GF Hard Wax Oil. For example, 1/4 tsp. of Hardener per ounce of Hard Wax Oil or 1/2 tsp. of Harnder per 2 fluid ounces of Hard Wax Oil. The finish can only be mixed once; mixed product will harden after 4-6 hours.  The combination of Hard Wax Oil & Hardener provides the best overall durability, and chemical and water resistance. Do NOT use General Finishes NCO catalyst.
2. Apply a thin coat with a trowel or non-woven synthetic pad. Spread evenly with a white non-woven pad or plastic spreader, one manageable section at a time. On large surfaces, use a white non-woven pad with a variable speed buffer or sander.
3. Let rest for 5 minutes.
4. Wipe off excess evenly with the grain & with light pressure using a clean terry cloth. Follow with a clean white non-woven pad until the surface is dry and smooth.
5. If a second coat is needed, wait 24 hours. Prep the surface with a gray non-woven pad before applying.

Ideal conditions: 70°F/21°C; 50% humidity. Cooler temperatures and higher humidity may prolong dry time. Use of the Hardener will shorten dry times.

After the surface has dried for 24 hours, you can buff to a slightly higher sheen with a white non-woven pad or terry cloth. 

Cleanup

Clean up application materials and hands with mineral spirits.

Disposal

Take GREAT CARE when disposing of product-soaked applicators. Application materials containing Hard Wax Oil products may spontaneously catch fire if improperly discarded. Immediately place all application materials soaked with this product in a sealed, water-filled metal container. Dispose of in accordance with local fire regulations. 

Spills

Clean up spills with mineral spirits immediately while wet. If oil and wax finishes dry, they are difficult to clean off any surface, clothes or carpet. Carpet may discolor if cleaned with mineral spirits.

Prevention

Protect your workspace with a tarp, your hands with gloves, and your clothes with an apron.

Life of Product

General Finishes products do not last forever, even when unopened. They are best used within 1 year. The life of the product may be extended with proper can closure and storage conditions.

Storage Tips

See our video: Tips for Storing Leftover Finishes 
Oil-based products start to harden and cure when exposed to oxygen. The following best practices will increase the life of your product:

1. Keep container tightly closed and sealed until ready for use, in the original container. Do not store in unlabeled containers.
2. Pry open sealed lids with a paint can opener by hooking under the lid's rolled edge. The use of a screwdriver can disfigure the rim and lid, impairing a complete seal.
3. Keep the lid closed while working. Decant what you will use into a bowl, paper cup, or plate, and close the can lid as you work. Every minute the can is open, the product is curing.
4. Containers that have been opened must be carefully resealed and kept upright to prevent leakage. Clean the chime of the can thoroughly with a paper towel before closing to create a complete seal. Product in the chime can be minimized by using a pouring lid, such as Fitsall. Avoid wiping used brushes on the lid.
5. Pound the lid in place using a rubber mallet to avoid distorting the chime or lid. Dents in the lid from direct contact with a hammer can impair a complete seal. Alternatively, place a flat piece of wood over can lid and firmly pound shut.
6. Avoid temperatures below 50°F/10°C or above 80°F/26°C. Frozen and heat-damaged product cannot be revitalized. Store in the original container protected from direct sunlight in a dry, cool and well-ventilated areas.
7. Do not store product in an attic, garage, in direct sunlight, or next to ignition source with heat and flames such as a furnace.
8. Store the can upside down to create a liquid seal, minimizing oxygen exposure from within the can. Decant the remaining product from the can before stirring.
9. Optionally, add Bloxygen. Bloxygen is an argon gas system that prevents oxygen and moisture from hardening leftover product. Because Bloxygen gas is heavier than air, it sinks to the surface of the leftover finish, creating a barrier between product and air trapped in the container.
10. Decant leftovers to a smaller, properly labeled container when the finish is almost used up to reduce the volume of oxygen in the container.
11. Use appropriate containment to avoid environmental contamination.
