How to Weatherproof Wooden Furniture

Updated March 23, 2017

Weatherproofing your wooden furniture preserves it for many years against the harsh elements of outdoor use. When making your initial investment on outdoor wooden furniture you should ask if the furniture is weatherproofed. If this is not the case, you will need to weatherproof it yourself to protect it against mould, mildew, ultraviolet rays and fading. In order to weatherproof your wood furniture, you need to coat it with a weatherproof sealer. Apply weatherproofing sealer with a brush or spry applicator.

Place a dust sheet on the floor beneath your piece of wood furniture. Use enough dust sheets to cover the work area to prevent the sealer from staining the concrete.

Wipe down the furniture with a damp cloth to remove excess dirt, dust or oils that will prevent the sealer from be applied evenly. Allow two hours for the wood to dry.

Open the can of weatherproof sealer. Stir the sealer with a paint stick to prepare the product for application.

Paint the surface in even brush strokes with your paintbrush. Work in small sections before turning or flipping the piece of wood furniture. Allow adequate time to dry as per the product's specific guidelines. Some weatherproofing sealers dry faster than others.

Lightly sand any drip marks with a 120-grit sandpaper to obtain an even finish. Apply a second coat. Apply the second coat no longer than 48 hours after the first application for best results. Most weatherproofing sealers fully cure after 72 hours.
