The following steps and products are recommended for best results.

  • Use a product such as BEHR PREMIUM® NO. 64 Wood Stain & Finish Stripper to remove loose wood fibers, latex, oil-based and 100% acrylic coatings on new or weathered wood.
  • BEHR PREMIUM® NO. 63 All-In-One Wood Cleaner MUST be used following NO. 64 to clean, brighten & neutralize wood.
  • When NO. 64 is not needed, use a product such as NO. 63 to clean and brighten the wood surface and to remove light to medium stains caused by mold, mildew, algae & fungus.
  • On new wood, use a product such as NO. 63 to remove mill glaze and open the pores of the wood. Rinse thoroughly and allow to dry before coating. Lightly sand any remaining wood fibers/fuzz.


For best results, a pad applicator is recommended over large areas.

  • Must apply between 40-90˚F (4.5-32˚C). Do not use if rain is expected within 24 hours. The wood surface must be completely dry before application.
  • Intermix multiple containers to ensure color uniformity. DO NOT THIN PRODUCT. Stir product occasionally throughout application. Test product for penetration and color on a small hidden area before proceeding.
  • Use a nylon/polyester bristle brush or pad applicator. Rolling should be limited to rough surfaces only.
  • Use a 3/8” nap roller. A high quality pump sprayer with a variable tip can be used. However, if a pump sprayer is used, work in small sections lightly saturating the surface and backbrush/roll immediately to remove excess and evenly distribute the finish.
  • Airless spray is recommended for experienced applicators only. Use a .015 - .019” tip. Maintain a wet edge when applying. Always backbrush during all application methods. Apply product end to end or to board lengths to prevent lap marks.
  • Over application of finish will lead to surface failure including peeling and cracking. Avoid applying finish too heavily. Coat wood on all sides for optimum performance.

Dry Time

  • 1-2 hours before recoat. Wait 24-48 hours before foot traffic. Allow 72 hours for full cure.


  • For disposal of empty containers and unused product, contact your household refuse collection service
