How to Stain a Composite Surface

Whether you want to compliment the trim or siding of your home, BEHR® has the right solution to refresh or change the colour of your composite deck.

For Best Results:

Prepare your surface by cleaning it with BEHR PREMIUM® All-in-One Wood Cleaner.

Apply stain with quality equipment and start with vertical areas first.

Apply even coats and allow ample dry time before exposing the surface to foot traffic and re-arranging plants and furniture.
