How to Seal Acrylic Paint on Wood for Outdoor Use

Acrylic paint is a popular choice for painting wood because it is easy to use, dries quickly, and is relatively inexpensive. However, acrylic paint is not waterproof, so it is important to seal it if you plan on using it outdoors. Sealing acrylic paint will protect it from the elements and help it to last longer.

There are several different types of sealers that can be used on acrylic paint. The best type of sealer for your project will depend on the specific conditions that the painted wood will be exposed to. Some of the most common types of sealers include:

Polyurethane: Polyurethane is a durable, waterproof sealer that is available in both clear and tinted finishes. It is a good choice for sealing painted wood that will be exposed to heavy wear and tear.
Spar urethane: Spar urethane is a type of polyurethane that is specifically designed for use on outdoor wood surfaces. It is resistant to UV rays and water, making it a good choice for sealing painted wood that will be exposed to the sun and rain.
Epoxy: Epoxy is a two-part sealer that is very durable and waterproof. It is a good choice for sealing painted wood that will be used in wet or high-traffic areas.
Varnish: Varnish is a traditional type of sealer that is made from natural resins. It is not as durable as polyurethane or epoxy, but it is less expensive and easier to apply.

Once you have chosen a sealer, you will need to prepare the painted wood surface before applying it. The surface should be clean, dry, and free of any dust or debris. If the surface is not properly prepared, the sealer will not adhere properly and will be less effective.

To apply the sealer, use a brush or roller to spread it evenly over the painted wood surface. Be sure to apply a thin, even coat and allow it to dry completely before applying a second coat. The number of coats that you need to apply will depend on the type of sealer that you are using and the specific conditions that the painted wood will be exposed to.

Once the sealer has dried completely, your painted wood will be protected from the elements and will be ready to use outdoors. Sealing acrylic paint is a simple and effective way to ensure that your painted wood will last for many years to come.
