All raw wood projects require preparation sanding before applying stain or wood conditioners. If you skip this critical step, your finish may be rough and uneven.

Preparation for Raw Wood Projects Prior to the Application of an Oil-based Stain
See our video: How to Prep Sand Raw Wood

1. Prep sand with 120-grit sandpaper followed by 150-grit sandpaper.
2. Remove dust with a vacuum, compressed air, a tack cloth or a water-dampened rag.  
3. Do not over-sand with fine-grit sandpapers; this will close and seal the wood grain, preventing ideal product absorption.

Preparation of An Existing Butcher Block Surface

1. Remove any food residue using a pastry scraper or spatula to gently scrape the countertop in areas where you find dried-on food or residue. Avoid gouging the wood by keeping the blade at an angle that just skims the surface.
2. Scrub the countertop using a scrub brush, Scotch Brite Pad or sponge and scrub the countertop with hot water and mild dish soap.
3. Rinse with hot water: Run a clean dishcloth through hot water and rinse the countertop several times.
4. Dry thoroughly with a clean dish towel or paper towel.

General Finishes Oil Based Pre-Stain Conditioner Application Steps

For use with oil-based stains.

1. Stir General Finishes Oil Based Pre-Stain Conditioner to reincorporate solids that have settled to the bottom of the can.
2. Do NOT thin.
3. Apply 1 coat of Pre-Stain Conditioner to raw wood using a clean cloth, a foam brush or paint pad applicator.
4. Pre-Stain Conditioner Natural can improve color uniformity over difficult-to-stain wood species such as pine. However, it will limit color absorption, so a darker wood stain may be required to get the desired depth of color.
5. Let Pre-Stain Conditioner penetrate the wood for 10+ minutes.
6. Wipe off excess with a clean, dry cloth.
7. Let Pre-Stain Conditioner dry at least 30 minutes, but no longer than 2 hours before applying stain, in ideal conditions: 70°F/20°C; 50-70% humidity. Do not wait longer than 2 hours, and never let Pre-Stain Conditioner dry overnight before applying a stain over it.

Cleanup
Clean up application materials and hands with mineral spirits or waterless hand cleaner, like Goop or Gojo. 

Disposal
Take great care when disposing of product-soaked applicators. Application materials, such as brushes and towels, containing oil-based 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-based 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 of the manufacture date listed on the bottom of the can. The life of the product may be extended with proper care and storage.

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 lid closed while working. Decant what you will use into a bowl, paper cup, or plate, and close 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 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 remaining product from the can before stirring.
9. Add Bloxygen can. 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.
