Although I was going to include this blog later in the series, I have gotten many inquires about staining pressure treated wood. It seems the main questions are how long to wait to stain a new fence, what product to use, and how to apply it.
The length of time to wait to stain or seal a new fence depends on the material used to construct the fence. Most fences in the Raleigh area are built with pressure treated southern yellow pine. But the thickness of the picket and how dry it is plays a factor in the proper time to stain. The most common picket used in this area is a 5/8″ thick picket. This picket always seems to be very dry when purchased. Due to this picket being fairly thin, the sun tends to warp and split this picket type. This picket can be stained as soon as it is put up. As a matter of fact, the sooner the better! A 3/4″ picket tends to stand up to the sun better. It can warp and split, but is less likely to due so then the 5/8″ board. It is not completely dry when purchased, and needs to weather for 3-4 weeks before being stained. Then there is deck board, or 5/4″ board, which is a full 1″ thick. This board is very hearty and is wet when purchased. This type of picket needs to weather for 4-6 months before staining!
We do not recommend a specific product to use when staining a fence, but it does need to have a few things in it. Of course, it needs to be an outdoor stain. It also needs to have a water sealer and UV protection in it. The water sealer keeps the water from getting in the wood and splitting it. The UV protection helps protect from the harmful rays from the sun that warp and split wood as well. A color, tint, or clear application will do fine as long as it has these items in it.
Application can be done by a brush, roller, or sprayer. We recommend a pump sprayer that can be bout at the home improvement store for about $30.00. Be careful not to spray bushes or flowers as it can damage or kill them.
