Wood Fencing Consideration

Wood fences are famous and widely used due to their ability to withstand decay and rot. Part of the fence post which has constant contact with the ground and is exposed to moisture and insects should be pressure treated with chemicals that keep away water and bugs so the wood will not get damaged.

New Installation

When you have a new fence installed, wait at least a year before painting and staining it so the chemicals used on the wood can dry out. Otherway you will seal the moisture inside and very fast you will end up with damaged fence. Pressure-treating ensures that the wood is protected from fungal decay and termites.

Ensure dry environment

Thorough Cleaning Every 2 to 3 Years

Every two to three years clean your wood fence to avoid dirt, moss, mildew, and graying, and after that apply UV inhibiting, water-repellant coating.

Reseal or Repaint After Cleaning

Painting and sealing should be conducted at the same time as cleaning, more precisely after.

Hose Down

Every few weeks, or when necessary, hose down your fence to get rid of any dirt, fertilizer chemicals, and other waste. None of this can hurt your fence but they will ruin the picture of a perfect aluminum fence, and for sure you don’t want that.

If hosing it down doesn’t help, after some muddy storm for example, and the bottom of the fence is caked with splatters of mud, wipe it down with some soft cloth, but never use something like a wire brush to remove dirt from the aluminum fence. Wash up first to dilute the dirt and then wash down to remove it away from the fence post. Let the fresh air do the magic and then wipe it down with a soft cloth.

Use chemicals and soap

For harder stains use CLR ( Calcium Lime and Rust Remover) which is not a dangerous chemical but still beware when you working near plants or vegetable gardens. In that case, apply the CLR with a rag. For areas that are more soiled and that aren’t coming clean with water or degreaser, use warm water with dish soap.
