How to Stain & Seal Wood Garage Doors

Natural wood garage doors give your house a striking, rustic appearance. To keep your wood garage doors looking good, it is important to stain and seal them. A quality stain and sealer will protect the wood from the elements and bring out its beauty and uniqueness.

Preparing and Staining your Wooden Garage Doors

Step 1

Clean the wood. Use a quality wood-cleaning product to remove any dust, dirt and grime that might interfere with the stain application. In addition, cleaning the wood will break "mill glaze," a condition that crushes the pores of the wood and prevents stain from penetrating properly.

Step 2

Brighten the wood (optional). Tannins are present in certain types of wood, primarily redwood and cedar. Tannins are a naturally occurring element that protects the living tree from fire and other damage. When the wood is disturbed, even after it has been harvested and milled, tannins can bleed to the surface and create a dark, unpleasant look. The wood-cleaning process can bring these tannins to the surface. If this happens, use a quality wood-brightening product to neutralize the tannins and take the wood back to its natural color.

Step 3

Allow the wood to dry thoroughly before applying stain. At least 24 hours is advisable.

Step 4

Apply the stain. Penetrating oil-based wood stain can be applied using a brush, roller or sprayer. Generally, only a single coat is needed.

Step 5

Back brush. The stain should completely penetrate into the wood within 15 minutes. After a half hour, use a dry brush to remove any excess material that has not penetrated the wood.
