Technical Data Sheet

Where to Use
Wood Conditioner is recommended for use on soft woods such as pine, fir, maple, or poplar. This wood conditioner needs to dry 8 hours before applying an oil based stain.

Ideal for use on soft woods which are being stained with or adjacent to hardwoods.

Surface Preparation
All surfaces must be clean, dry, and free from dirt, wax, or grease. If persistent wax exists, remove with fine steel wool saturated with paint thinner or alcohol. This product does not take the place of sanding sealer. It is a pre-stain treatment only.

Bare Wood: Sand the wood thoroughly with medium grit sandpaper and progress to fine grit sandpaper. Always sand in the direction of the wood grain. Sand smooth and remove all dust.

Previously Finished Surfaces: Strip the surface completely down to bare wood with paint or varnish remover, making sure all previous finishes are removed. Surface must be sanded smooth. Remove all dust.

Note: DO NOT use a tack rag to remove dust, as it may leave a residue that will interfere with adhesion.

Stir product thoroughly with a circular, lifting motion to disperse contents evenly.

  1. Apply with a polyester or nylon brush. Ensure entire surface has been coated.
  2. Allow Wood Conditioner to penetrate the surface for 5 to 15 minutes. Remove excess by wiping with a clean rag. Do not leave a surface film; work in a small area so the product cannot set up.
  3. Apply stain over Wood Conditioner after 8 hours. If stain is applied before 8 hours, a darker color may result with less uniformity control.

Helpful Hints
Color depth may vary according to type of wood, stain and application technique. To ensure that your finished color is accurate, we highly recommend you test your technique, wood stain, and wood type before you start your project.

Do not thin. Use as packaged.

Approximately 400 to 500 square feet per gallon depending upon method of application, type and porosity of wood.

Drying Time

Using a cleaning solvent, such as paint thinner or mineral spirits, is recommended for cleanup. The use of paint thinners or mineral spirits may violate VOC compliancy in your area. Check with your local government agencies to ensure proper compliancy.
