Typically, a fence requires one to two coats of stain. The exact number can vary depending on the porosity of the wood. For specific guidance, it's best to check the manufacturer's instructions. After applying the first coat and letting it dry completely, you can assess the finish. If it appears patchy, uneven, or you want a more saturated color, a second coat is recommended. An extra coat can also help cover lap marks.

Traditional bamboo fences use twine to attach pickets to posts and stringers, but you have to keep an eye on the twine, as it will deteriorate over time. Alternatively, you can fasten bamboo pickets to framing using fence screws.

While power washing isn't a requirement before you stain a fence, it can make the job much easier and faster while reducing manual labor requirements. The stain will not work if the wood is full of dirt and dust, so power washing, sometimes called pressure washing, is a fast and effective way to prepare the wood for staining. Remember that you need to stain or repaint relatively soon after the wood has dried so that there isn’t time for dust and dirt to build up again. 

The depth of your post hole depends on your post length. If you decide on a two-rail fence, the posts are likely 6 feet long. You want your hole to be at least 1/3 of the post length. In this case, your post hole should be two feet deep.

If you opt for a three-rail fence, the posts will typically be 7 feet long, meaning your post hole should be 28 inches deep.
