Using a deck sealer offers several important benefits:

Moisture Protection: Sealers prevent water from soaking into the wood, reducing the risk of rot, mold, and mildew.

Enhanced Durability: A sealed deck is more resistant to cracking, splitting, and warping.

Clear Sealers: Offer basic moisture protection while preserving the natural look of the wood.

Solid Sealers: Provide maximum protection and color coverage, similar to paint but with better durability.
