For expert guidance on properly preparing your wood surfaces, refer to our how-to steps below.

Make sure to follow all product label instructions.


  1. Step 1

    Wet surface with water prior to cleaning. Apply cleaning solution liberally with a pump sprayer, mop, brush, or roller. Keep the surface completely wet with the solution for 10-15 minutes.

  2. Step 2

    Scrub the surface using a stiff bristle broom or brush. The solution will foam.

  3. Step 3

    After scrubbing, thoroughly rinse the surface area with clean water at normal pressure or using a pressure washer at low setting (500-1200 psi).

  4. Step 4

    Let surface dry.  Next, lightly sand any loose wood fibers with medium grit sandpaper.


  1. Step 1

    For interior or exterior wood applications, Use BEHR PREMIUM PLUS® Multi-Surface Primer and Sealer.

  2. Step 2

    To apply the primer, use a high-quality 3/8 - 1/2" (9.5 - 13 mm) nap roller cover, nylon polyester  brush or airless sprayer. 

  3. Step 3

    Stir the primer occasionally. Do not thin if using a roller or brush. If using a sprayer and thinning is required, then thin with up to 1/2 pint (473 ml) of water per gallon of primer. Heavy stains may require two coats.

    The primer will dry to touch in 30 minutes and be ready to topcoat in 1 hour. Use the primer when air and surface temperatures are between 50-90 degrees F (10 - 32 degrees C). Clean up with soap and water.
