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.

For your home's next project consider using the 6 in. x 6 in. x 8 ft. Pressure-Treated Pine Timber. The pressure treatment helps protect this wood from insect damage, weather damage and decay making it ideal for a variety of applications including decks, play sets, landscaping, stair support and walkways and other outdoor projects where lumber is exposed to the elements. It can also be painted or stained to suit your needs.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.

Questions & Answers


What is the actual dimensions of your 6 x 6 post?

Asked by Ron August 21, 2018

5 1/2x5 1/2

Can these be cut down to smaller dimensions? I’m only needing one that’s 1ft in length.

Asked by Ryan March 13, 2018

I'm not sure if you can buy them in 4'. I had to buy an 8' for 56" worth. They only had a recipricator saw on site to cut it. I'd call your home depot and ask them. You could use the left over for a mail box post. Cut it with a skil circular saw.

Will home depot cut a 6x6x8ft board in half?

Asked by Rick April 23, 2018

Depends on the local store, call and ask. They might not have a table saw on site. They had a reciprocater saw to cut mine down for a mail box post.

can this wood be stained?

Asked by Pete May 16, 2018

Yes, you can stain this wood. You need to let it weather and allow the wood to dry at least 30 days, longer would be better.

Can this be used to put on the dirt and cement for base of deck? Right on top of dirt. If not how long is it estimated to last lating on dirt?

Asked by Ray April 9, 2018

Yes, you use pressure treated lumber outside on ground or concrete.

Can these be uses for a retaining wall?

Asked by Ever July 17, 2019

No, Heavy Duty UC4B S4S SYP for Critical Structural lumber is what is needed. Please check with your local PRO associate to see if this lumber can be special ordered in your area.

Can this be used to brace floor joists under a pier and beam house?

Asked by B10V July 19, 2017

We recommend, and building code will require going to a “Critical Structural” loading vs. regular Ground Contact treated wood to be under a house of any kind. This will need to be special ordered at the Contractor Pro Desk, and is called “UC4B”. This cannot be used submerged in salt water. Consult with an architect or engineer for strength/spacing information, you will also want this to be Kiln Dried After Treatment (KDAT) for strength purposes.

What is the load bearing rated at for 8 ft.

Asked by Dan May 22, 2018

Good question. As I was thinking of using these as porch posts. These are a lot fatter than a normal post with design carved in so they should work no problem.

How much does this weigh?

Asked by Vito April 15, 2019

50 lb. +

Whats the difference between this one and the pressure treated that doesnt state “ground contact”? Isnt pressure treated all rated for ground contact

Asked by KO June 1, 2020

KO, There is a difference between wood treated for ground contact and wood that is treated, but should not be used if ground contact is needed. Read the following for more information about pressure-treated wood/some of the codes/information that you'll find on the end tag of lumber: Wood treated to (UC3B) above-ground standards is ideal for use in light-duty situations where wood will not be in contact with moisture or the ground. Railings, balusters and certain deck board installations may be appropriate for above-ground treated lumber. Wood treated to (UC4A) ground contact standards is ideal for general-use situations where the wood may contact moisture, the ground, or be installed in a manner that subjects the wood to comparable ground contact conditions – such as poor ventilation, tropical climates or frequent exposure to moisture. Further, Posts, stair stringers and certain deck board installations also require ground contact treated lumber. Wood treated to (UC4B) heavy-duty standards should be used in very severe environments or for critical structural components such as foundation piling. Always consult local building codes for additional requirements for specific structures. Wood treated to (UC4B) heavy-duty standards should be considered when the wood will be used to support a permanent structure. UC3B treated lumber is for above ground, not for near ground, light-duty use UC4A treated lumber is for ground contact, general use UC4B treated lumber is for ground contact, heavy-duty use

Good product for building retaining walls
Used around 100 of these to build out a retaining wall. Quality was good, no warping. Boards varied in weight given how much water was retained in wach, but didn’t impact product

I would have given it a better rating but when I got it home a knot in one corner side fell off. It was used to lift a bird feeder and pole high enough for my Wife to see it from our kitchen window.I cemented it 1 1/2 feet in the ground with slots in the other end for the in ground bird feeder pole to slide into.I reinforced it with two sets of 3 inch bands just for extra bracing. At the top of the 6x6 timber I had to use two bands of flashing wrapped around it to keep a pesky ground squirrel form being able to get to it.But don't worry my Wife has a separate feeder for him too.
