How To Refinish Outdoor Teak Wood Furniture

Teak wood is a highly prized material for outdoor furniture due to its durability, natural oil content that repels water, and beautiful rich color. Over time, however, teak furniture can become weathered, faded, and lose its luster. Refinish your teak furniture to restore its original beauty and extend its lifespan. This process involves cleaning, sanding, and applying a protective finish.

Step 1: Cleaning

Before sanding or applying any finish, it is essential to thoroughly clean the teak furniture. This removes dirt, grime, mildew, and any old finish that may be present. Begin by using a stiff-bristled brush to scrub the furniture with a mild soap and water solution. For stubborn stains, a teak cleaner or a solution of oxygen bleach and water can be used. Rinse the wood thoroughly after cleaning, and allow it to dry completely before proceeding to the next step.

Step 2: Sanding

Sanding is crucial for creating a smooth surface and removing any imperfections before applying a new finish. Start with coarse-grit sandpaper (80-120 grit) and use a sanding block to sand the entire surface of the teak furniture. Work with the grain of the wood to avoid scratches. Move on to a medium-grit sandpaper (120-180 grit) and then a fine-grit sandpaper (220-240 grit) for a progressively smoother finish. Always sand in the direction of the wood grain to avoid creating cross-grain scratches.

During the sanding process, pay close attention to any areas that require extra attention, such as corners or edges. Avoid excessive sanding to prevent removing too much of the wood’s natural oils. After sanding, vacuum or brush away all sawdust and debris to ensure a clean surface for the finish.

Step 3: Applying the Finish

Teak furniture can be finished with a variety of products, including teak oil, teak sealer, or a clear polyurethane varnish. Teak oil is a natural oil that penetrates the wood and enhances its natural color. Teak sealer is a water-based sealant that protects the wood from water damage and UV rays. Polyurethane varnish creates a durable and protective coating that resists scratches, stains, and moisture.

Before applying any finish, read the product label carefully for specific instructions and drying times. Generally, the finish should be applied in thin, even coats. Allow each coat to dry completely before applying the next coat. For best results, apply the finish in a well-ventilated area, and wear protective gloves and a mask.

If using teak oil, apply a liberal coat to the entire surface of the furniture. Rub the oil into the wood with a clean cloth and allow it to penetrate the wood for several minutes. Wipe away any excess oil with a clean cloth. Repeat the process as needed until the desired level of saturation is achieved. Teak oil should be applied at least once a year to preserve the wood.

If using teak sealer or polyurethane varnish, use a brush or a spray gun to apply the finish. Avoid applying too much finish in one coat, as this can cause uneven drying and streaking. Allow each coat to dry completely before applying the next coat. Two or three coats are generally sufficient for optimal protection. After the final coat has dried, buff the furniture with a soft cloth to enhance its shine.

Refinishing teak furniture is an excellent way to restore its beauty and protect it from the elements. With proper cleaning, sanding, and finishing, your teak furniture will retain its natural beauty and grace for years to come.
