Seal Your Sign for Outdoor Use
To seal a wood sign for outdoor use, you will need the following materials:
Wood sign
Clean cloth or brush
Exterior wood sealer
Here's how to get started:
If the wood sign has been painted or stained, allow the finish to dry completely before sealing.
Choose an exterior wood sealer that is appropriate for the type of wood and the intended use of the sign. There are several types of sealers to choose from, including water-based, oil-based, and polyurethane.
Follow the manufacturer's instructions for application of the wood sealer. In general, you will want to apply a thin, even coat of sealer to the wood sign using a clean cloth or brush. Be sure to cover all surfaces, including the edges and any decorative elements.
Allow the wood sealer to dry completely according to the manufacturer's instructions. This can take anywhere from several hours to several days, depending on the type of sealer and the humidity and temperature of your work area.
Once the wood sealer is dry, the wood sign is ready for outdoor use. You can hang the sign on a fence, gate, or wall using nails, screws, or brackets, or you can display it on a stand or pedestal.
To maintain the longevity of the wood sign, re-seal it every few years or as needed. You can tell it's time to re-seal when the wood becomes dry or the finish starts to peel or flake.
