What is Wood Filler?

Wood filler is a versatile product used in woodworking and construction.

It is designed to fill gaps, cracks, and imperfections in wooden surfaces, providing a smooth and uniform finish.

When it comes to decks, wood fillers serve a crucial role in maintaining their integrity and appearance.

Why Use Wood Filler on Decks?

Decks are constantly exposed to the elements, including rain, snow, and harsh UV rays.

This exposure can cause the wood to warp, crack, or develop unsightly holes and gaps.

Wood fillers help to address these issues by sealing gaps and cracks, preventing further damage, and enhancing the deck’s aesthetics.
