How to Seal Paint

Sealing protects the wood from water damage.

After you paint furniture, you want to seal the paint so it will last a long time. Sealing it also protects the wood from water damage. You can use polyurethane to seal your painted wood, but you must be patient. Polyurethane dries much slower than paint. Depending on the brand you purchase, it can take up to 24 hours to dry. But it is long lasting and does a superb job of sealing your paint. Confirm the paint is dry before starting the sealing process.

Things You'll Need

• Mineral spirits
• Polyurethane
• Plastic bowl
• Wooden mixing stick
• Natural-bristle paintbrush
• Razor blade

Instructions

1. Mix one part polyurethane with two parts mineral spirits in a plastic bowl with the wooden mixing stick. Apply it to the painted wood with the paintbrush using long, even strokes. Allow the mixture to dry for 24 hours.

2. Apply one undiluted coat of polyurethane with the paintbrush.

3. Apply another undiluted coat of polyurethane the same way as the previous step. Allow this to dry for 24 hours.

4. Remove any dried drips from the polyurethane carefully using the razor blade. Don't cut the wood; simply remove the drip.

5. Apply one final coat of polyurethane. Allow it to dry for 24 hours.
