6X6X14 Treated Post Lowes (2024)

FAQs

How long will pressure treated 6x6 post last in the ground? ›

As a whole, the post and lumber specimens indicate an expected durability of over 50 years for creosote-treated wood and over 60 years for wood treated with pentachlorophenol, copper naphthenate, ACZA, or CCA.

Its weight per ft³ is 33 lb/ft³ for Douglas fir or 37 lb/ft³ for Southern Pine. Therefore the 6″× 6″× 16′ weight is 4*33 = 132 lbs for the Douglas fir or 148 lbs for the Southern Pine. Assuming you are referring to a 6x6x16 cinder block, they typically weigh around 35-45 pounds each.

How Long Does Pressure-Treated Wood Last? It depends on the climate, the type of wood, its uses, and how well it's maintained. While pressure treated poles can stay up to 40 years without any signs of rot or decay, decks and flooring might only last around 10 years.

The general rule of thumb when setting a post is that the depth of the post's hole needs to be one-third to one-half of the actual above-ground height of the post. So, a six-foot-high finished post ideally needs to be buried three feet into the ground.

Fill the first three inches up with gravel so the end of the post doesn't come into contact with the dirt. Gravel allows water to drain quickly away from the post and into the soil. Be sure to place the post in the center of the hole. Finally, fill the entire hole up with cement to the top.

What is the maximum weight that a 6x6 lumber post can hold? The maximum weight that a 6x6 lumber post can hold depends on several factors such as the type and grade of lumber, the length of the post, and the spacing between posts. However, on average, a 6x6 lumber post can hold up to 30,000 pounds of vertical load.

If you assume that the deck will be loaded with a live load of 40 psf, the total load on the beam will be 3,200 pounds. This is well within the load capacity of a 6x6 Lam beam, so you should be fine.

If you assume a conservative 1400psi allowable bending stress, a single 6x6 with 12' span can support about 2000 lbs. So your double 6x6 can support at least 4000 lbs (possibly more if you do a good job bonding the two members together so that there's no slip between the faces).

Should I paint a fence post before putting in the ground? ›

Paint the entirety of post in waterproofing sealant using a large paintbrush, even the section which will be beneath the ground. Pour waterproofing sealant into a bucket, immersing the end of the post (which will be buried below ground) into the sealant.

Yes, the short answer is absolutely you can paint pressure treated wood easily using high quality exterior primer and latex paint, but you should wait until it dries first, wash and scrub off all the excess treatment chemicals that seep out, then after it dries once more it's ready for primer and paint!

Dig post hole so diameter of the hole is 3 times the width of the post (i.e., the hole for a 4” wood post should be about 12 inches wide). The depth of the hole should be 1/3-1/2 the post height above ground (i.e., a 6-foot tall fence would require a hole depth of at least 2 feet).

Concrete for a 6 x 6 Post

First of all, the diameter of the hole you need per pole is now going to be 18 inches. If you're still building a 6-foot tall fence, with 2 feet of your post being underground, you would need at least 7 bags of concrete per post.

However, a general rule of thumb is that a 6x6 post can support a span of up to 10 feet. If you want to span 28 feet between two 6x6 posts, you may need to use additional support, such as beams or trusses, to distribute the weight evenly and prevent sagging.

Simply setting the posts in concrete does create a condition that will accelerate rot in the bottom of the posts. With pressure-treated posts, the rot will be slow.

Pour waterproofing sealant into a bucket, immersing the end of the post (which will be buried below ground) into the sealant. Allow the post to sit in the bucket of sealant overnight, then leave to air dry.

Ground contact wood can last anywhere from 3 to 7 years, depending on factors such as the type of wood, treatment, and environmental conditions. To ensure longevity, consider pressure-treated wood and regular maintenance such as sealing or staining.

Ground-contact pressure-treated lumber can be used either above ground or in contact with the ground.
