Extend Its Life

Wood fence sealant helps to extend the life of your wooden fence. Wood swells when it is wet since it absorbs water that falls on it and from the environment. When the sun is up, the wood dries, and it contracts.

These reactions to the various weather patterns cause the wood to wear and tear. You will see cracks start to appear on your fence.

Your wood fence should last for about 15 years. If you don’t seal the wooden posts that make the fence, you might end up replacing it in five years.

The sealing compound is a chemical infusion in the wood that makes it waterproof. Moisture in the atmosphere and water drops that land on the wood cannot be absorbed. Thus the wood doesn’t have to undergo the wet and drying processes that make it weak and cause damage.

Keep it Attractive

Sealing the wooden posts of your fence also keep your fence attractive for longer. A new wooden fence is attractive to look at. It looks fresh, bright, and shiny. You would wish for the fence to look like this for all its useful life. Sealing it will ensure that it does.

If you don’t seal the wood on your fence, the reaction to weather forces will force it to discolor. Absorption of water and rapid drying in the sun causes the wood to change color and age. Sealing the wood prevents these reactions to the weather from taking place. Thus, the wooden posts can retain their color for the rest of their useful life.

Save Money And Time

Sealing your wooden fence also ensures that you save time and money.

As part of the maintenance of your wood fence, you need to inspect it for damage and repair the damage immediately. Most of the damage on the fence occurs from rotting and decaying. When you seal your fence, it will not rot or decay.

Additionally, your fence will live to its maximum end of life. You will not spend money installing a new fence every few years.

When Should You Apply Sealant On Your Wood Fence
