Any stain that is designed for exterior use will work to stain pressure treated wood. While you will find oil-based stains and latex stains, most homeowners prefer using oil-based stains for pressure-treated wood. Oil-based stains completely soak into the wood, creating a barrier against water penetration.

Not only can you stain treated wood, painting and staining pressure-treated wood is actually good for your new deck. Although the treated wood doesn’t need to be protected against rot, staining it will help reduce surface cracking. The kind of stain you put on your deck and when you apply it depends on the type and condition of your treated wood.

Stain the pressure-treated wood using a paint pad applicator, which is easier than brushing a large deck or structure by hand and more accurate than using a pressurized sprayer. Use a paintbrush to stain between cracks and problem areas. Usually no more than one coat is needed.
