Can you use Flex Seal Paint on Wood?
Flex seal paint on wood makes the wood waterproof, rot-resistant, and scratch-resistant and a coat of flex Seal will protect indoor and outdoor furniture from UV light, moisture, and fungi attacks.Flex Seal protects wood by seeping into the fibers and sealing it from the inside.
To apply Flex Seal to wood, first, clean the surface of the wood with a mild soap and water solution. Next, roughen up the surface of the wood with sandpaper to help the Flex Seal adhere better. Once the wood is dry, apply a generous amount of Flex Seal with a brush, making sure to get into all the cracks and crevices. Allow the first coat to dry for at least 24 hours before applying a second coat.
