How to Protect Outdoor Wood Furniture From the Elements

Redwood outdoor furniture does not require a sealant.

One of the misconceptions about outdoor, or treated, wood is that it withstands water. Outdoor wood products are injected with chemicals that prevent critters from eating the wood, but it is not protected from water and the elements. Adding the protection is easy.

Things You'll Need

• End-cut solution
• Water sealer
• Paintbrushes

Instructions

1. Paint the cut areas of pressure treated outdoor wood furniture with two coats of end-cut solution. This is a thin liquid that soaks into the wood providing the same protection that is injected into it.

2. Select a water sealant that meets your needs. A good water sealant causes water to bead up and roll off of the item. Higher-quality water sealants also provide protection from ultraviolet rays to help maintain color and appearance.

3. Thoroughly coat your furniture with the water sealer, following application directions on the container.

4. Allow to dry

Tips & Warnings

• Redwood needs a clear sealant to maintain its fresh-cut color.

• Outdoor wood like cedar, cypress and tropical hardwoods do not require water sealants.

• Specially made covers can protect your furnishings from water, particularly if they are fitted with cushions.

• Water sealers have a limited effective life. You need to recoat on occasion, based on the environment your project is in and the quality of the sealer you used.

• Some sealers have fumes that are not healthy to breathe, you may need to use a respirator.
