How to Waterproof a Fence
- 1). Splash water on the wood fence. If the water soaks into the wood, it's time to apply a sealant to the fence.
- 2). Hose the fence down with water to remove any dirt and debris from the fence. Use a pressure washer to help remove stubborn debris. Allow the fence to dry completely. This could take a couple days.
- 3). Choose the finish. Water sealants come in both clear and tinted varieties. Selecting a tinted variety can restore color and luster to the fence.
- 4). Pour the sealant in a flat-pan, or paint trough.
- 5). Dip a long or short handle rolling brush, or paint brush into pan, and move the brush around so it's coated evenly. Make sure you are using a fresh, clean brush on the roller frame.
- 6). Roll the brush onto the fence. Put pressure on the brush so sealant gets into the grooves, cracks and crevices.
- 7). Apply the sealant to the other side of the fence.
- 8). Spray water on the fence after the sealant has completely dried; drying could take several hours. If water beads and doesn't soak into the wood, you have sealed the fence. If not, apply an additional coat of sealant to the wood.
