Preventative Maintenance Plan

1. Depending on the location of your outdoor project with regard to direct sun exposure, foliage coverage, etc., it may be sufficient to clean/brighten and recoat every two years. 2. If you decide to wait two or more years to perform your next cleaning/brightening, you may want to use a power washer. Be sure that the cleaner/brightener you use contains a mildewcide.

Choosing The Right Stain Or Paint

When determining the right stain and paint for your deck, consider what color will best enhance the wood's finish.

Paint or Stain Tips

If you desire to paint or stain the treated wood project, it is important that the wood be dry enough to accept a coating. The best way to determine if the wood is sufficiently dry to paint or stain is to sprinkle droplets of water onto the wood. If the water droplets are absorbed, the wood is ready to be painted or stained. If the water droplets bead on the surface of the wood, it is too wet. You should wait a few days before attempting to paint and stain the wood.

Balusters & Spindles

Pressure-treated boards are treated for protection against termites and rot. Ideal for a variety of applications including decks, play sets, landscaping and other outdoor projects where lumber is exposed to the elements. When used properly it is both safe and environmentally friendly.Treated wood is typically still wet when it’s delivered to The Home Depot or job site. As it dries, you should expect slight changes in width and length. As lumber dries, it may split, cup and warp. This is more likely to occur to occur in lower-grade boards, where knots and uneven grains are already present. Each piece of lumber is unique and carries physical characteristics that may include the following: knots, warping, shrinkage, swelling and/or splitting.
  • Made of pine
  • Can be used in ground contact applications
  • 1 in. x 4 in. x 4 ft.
  • Can be painted or stained
  • Significantly improved corrosion resistance for metal fasteners
  • WeatherShield includes water repellant in the treatment process
  • No two pieces of lumber are the same.
  • Color, grain pattern and texture will vary as well.

Questions & Answers


Is this the correct size backer board to hang my bedroom sliding door?

Asked by Jessie22 March 3, 2021

Hi Jessie22, It sounds like you are referring to a barndoor style arrangement - not a sliding pocket door. We're not sure if you have seen Home Depot's excellent tutorial on how to install your own sliding door, but just in case, instructions can be found by first scrolling to the bottom of Homedepot.com, looking under Resources then DIY Projects and Ideas, then Home Improvement Ideas, Project Guide, and finally, How to Install Barn Doors. As we don't know the size of your door, you'll have to decide if just one single pressure-treated board is enough to accommodate the width of the door and the distance that it needs to slide open fully, but you've got the required 1 in. thickness covered for the backer board. Best of luck with your new bedroom door.

Is there a waiting period before pressure treated board can be primed & painted ?

Asked by Art October 12, 2020

Art, We recommend giving your boards a decent drying time. First of all, if the wood has not been used, lay it flat with separators between boards. Make sure that the wood remains covered. Depending on how wet it is, you might want to wait a few months. To determine if pressure treated wood is dry enough to stain or paint, try the “sprinkle” test. Sprinkle water on the wood: if the wood absorbs it within 10 minutes, plan to stain as soon as possible. If the water beads or pools on the wood surface, the wood needs more time to dry.

Does the kind of wood treatment make it safe for use in a raised veggie bed?

Asked by MC April 14, 2020


What kind of the trees are they made from?

Asked by Judy February 6, 2020

I believe pine

is this board strong enough for decking on a porch? What makes it "appearance grade"?

Asked by Bronze March 15, 2019

The wood is pretty soft, like cedar. I'm not sure this would make good decking.
