Wood Conditioner

Product Details

This is a pre-stain, clear wood sealer that enables uniform stain application on soft woods, such as fir, pine or hemlock.  Using this product helps to avoid the appearance of uneven, blotchy staining.

*Old Masters Wood Conditioner is also available in a VOC compliant formula for OTC states and South Coast Air Quality Management District. This formula has a longer open time before stain must be applied. See product instructions for more information.


Where to Use
Wood Conditioner is recommended for use on soft woods such as pine, fir, maple or poplar. It can be applied under oil or water-based stains, but stain must be applied over Wood Conditioner within two hours.

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 in its usage. 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.

  • Apply with a polyester or nylon brush. Ensure entire surface has been coated.
  • Allow Wood Conditioner to penetrate surface 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 can not set up.
  • Do not allow to dry thoroughly. Stain must be applied over Wood Conditioner within 2 hours.

Helpful Hints
Color depth may vary according to type of wood, stain and application technique. To assure 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
Do not allow to dry thoroughly. Stain must be applied over Wood Conditioner within 2 hours.

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.

To avoid spontaneous combustion during temporary storage, soak soiled rags and waste immediately after use in a water-filled, closed metal container.

Proper Surface Preparation

Proper surface preparation can be the most important step of any stain or finish project. Below are some helpful tips that will help you achieve a professional looking finish every time.

FILLING WOODGRAIN Some open-pore wood species or woods with large imperfections may require an additional step to prepare the surface for staining and finishing. Creating a smooth finish on these woods can be obtained by using Old Masters® Woodgrain Filler. Use on hardwoods, such as oak, ash and mahogany. Use as directed.

CONDITIONING Some woods like pine, fir, maple and poplar absorb stain unevenly creating a blotchy appearance. Old Masters® Wood Conditioner is a clear wood sealer which enables uniform stain application under oil or water based stains. Stain must be applied over Wood Conditioner within 2 hours. Ideal for use on soft woods which are being stained with or adjacent to hardwoods.

SANDING SEALERS Use a sandable basecoat or sealer prior to the application of varnishes or polyurethanes. Old Masters® Oil-based and Water-Based Sanding Sealers may be applied to all types of bare or stained woods. Using these products helps to promote a smooth, fine finish.
