Posts & Spacing
One very common mistake in building a wood fence is not setting the posts deep enough. The holes for the posts have to be two feet deep and eight feet apart.
When using a fence post hole digger to make such holes, using it at an angle to make an anchor area at the bottom of each post hole. Doing so will ensure that posts will be more secure and stable.
Timber Posts Don’t Stick to the Concrete
Most people aren’t ware that wood does not stick to concrete. In construction sites, wood forms are utilized to frame concrete. And when the concrete is completely dry, the nails holding the wood frame will be removed and the wood forms will just fall off.
So, the bottom two feet of every post for your fence should be covered with black roof tar to help the concrete stick to the wood post. The tar also helps prevent insect infestation and rotting.
Not Letting the Concrete to Set Up
Another very common mistake when building a wood fence is that concrete isn’t allowed to become completely dry before starting the installation process. When the installation is started too quickly, it will most probably knock the fence posts out of level. And if the concrete isn’t completely set up, there may be too much space between the concrete and the post.
Not Using Enough Rails
Many DIY fence builders use just two rails between the posts. But one of the best ways to build a wood fence that could endure the test of time is to enhance its strength and stability by using three fence rails.
Install the slats not mote than eight inches below the bottom rail or above the top rail. Doing this will help ensure that the wood fence will be strong enough for many years to come.
