Brush Your Pergola

Starting with clean surfaces is the key to all wood preparation and preservation.

Mold, rust, leaves, dust, chemicals, and anything that might be blown in on the wind will accumulate on your pergola's wooden surfaces. Debris left behind may attract insects or retain moisture, potentially causing mold or wood rot.

  • Sweep or brush away loose particles from cracks and crevices, or between boards

  • Use a small brush or hand broom to sweep down any nooks or crannies in the structure

Clean Your Pergola

Skip the pressure washer and heavy duty cleaning solutions that may cause damage to the pergola’s delicate wood or finish. Instead, use Olympic Premium Deck Brightener & Wash to remove mildew, rust and tannin stains on wood or composite materials. 

Use a soft-bristled cleaning brush and garden hose to gently scrub and rinse away any surface stains that were not removed by sweeping or brushing.

Olympic Staining Tip


Always test a small, hidden area, using the same number of coats you will be using on the siding and let it dry so that you can be sure to get the wood stain color you want.

Step 5

Stain Your Pergola

Apply wood stain in this order — overhead, vertical surfaces, then floor. For darker wood stains, it is especially important to work from the top down and protect your floor from drips.

  • For clear, toner and semi-transparent stains, apply one thin coat with a high-quality brush, roller, paint pad, or spray.

  • For solid stains, apply two thin coats of deck stain with a brush, roller, or paint pad.

  • ​To avoid lap marks, apply to a few boards at a time, keeping a wet edge.

  • For best results, backbrush into the surface to work finish into the wood and ensure the coating is even.

  • Treat all areas of the wood, including joints, edges and ends.

  • Let dry thoroughly before replacing furniture or walking on stained floor boards.
