About This Product

For 18-years, Post Protector has provided simple, slide-on barrier protection for in-ground posts. It works in conjunction with the chemical preservative as an important additional layer of protection against soil-dwelling and atmospheric decay fungi and insect infestation. Its first important to understand decay. Many believe that moisture CAUSES decay. Moisture is not the cause of decay but is 1 of 3 conditions needed for decay to occur. The conditions: 1 Moisture, 2 Oxygen and 3 Suitable temperature. These conditions enable the soil-dwelling or atmospheric decay fungi, as well as termites and other subterranean insects, to feed on the wood fiber. So the Decay/Degradation of ground-contact wood is not CAUSED by moisture but by the action of wood destroying organisms feeding on the wood. The chemical preservatives protection strategy is to poison the wood fiber, rendering it an unsuitable food source for the wood destroying organisms. The downside to that approach is that all chemical preservatives eventually lose resistance to decay and insect infestation. Post Protector becomes the perfect complement to the pressure treated (or cedar) post by simply providing a physical barrier isolating the post so the wood-destroying organisms have NO access to the post.

Highlights

  • Simple slide-on installation

    I want to use a vinyl post jacket with a cap for a 4”X4” post to protect the above ground potion of the post. If I add the post protection to the bottom of the post can the vinyl jacket still be used? Can the jacket be slipped over the protector?

    Answer This Question

    Well, I got both parts. I was hoping to slide the “post jacket” over the top edge of the “post protector,” fully encasing the post. The “post jacket” will not fit over the post “protector” - same size. I will use caulk & a steel post guard for the gap.

      i imagine the water gets in from the top. does it have somewhere to leech out? or will the timber be sitting in water. Do you seal the top?

      Answer This Question

      1. Leave the base open to permeable soil/gravel. 2. Leave the top of the sleeve ABOVE the average flood level to limit amount of water entering. 3. Very little moister will seep between post and sleeve, unless sprinkler soaks post daily.

        Can this go into concrete? Also could you wrap it with some type of z tape on the top of the wrap?
        ByAug 18, 2023
        1 Answer | 
        Answer This Question

        Yes, the 4 in. x 4 in. x 42 in. In-Ground Fence Post Decay Protection can be installed in concrete. As for wrapping it with Z-tape, while the manufacturer doesn't specifically recommend it, you can certainly do so. It's made of HDPE, a durable plastic material, so the tape should adhere without issue.

        I'm in SW Florida. Maybe concrete around the sleeves and remove the fence sections when Hurricane ? Ian 2.0 hits again later this year. It's true. Dr. Fauci told me

        Paint it the way you would vinyl siding. Caulk the space between the post and sleeve. Seems to be holding up well after 8 years

          I don't see why not, it's a plastic surface so use the appropriate paint for an exterior plastic surface. I'd probably use an enamel spray paint.

            Seems this will definitely extend the life of the post. Cut the sleeve to the depth of the hole plus about 4-6 inches so it is above the dirt line. I drilled the weep holes in the bottom, used the included rubber gasketed screws to attach the sleeve to the post. Put a couple handfuls of gravel in the hole, put post in and poured a bag of cement in. Centered post and let cement cure 24-48 hours. Came back and sealed where the sleeve ended at the post with flex seal (caulk would work too). Hopefully this lasts a loooong time and I don’t have to replace the post for some time.

            They are easy to install. Just slip them over the bottom of the post and put the post in the ground. I did not screw them in figuring that if the post has a problem I should be able to work the post out without having to pull the post-protector out of the ground.

            Great Product and Excellent Service
            I've used these post protectors before building a fence around our organic garden. Didn't want the pressure treated wood to leach into the garden. I also sealed around the tops with 100% silicone. I did have a problem with the order, wrong size sent. I called Home Depot customer service and they got Ken from Post Protectors on to correct. Everyone was very helpful and took care of the mistake right away. This is why I gave them such a good review. Anyone can make a mistake but it's how you handle it that makes a difference. They did just that, Thanks Everyone.

            Not as thick as I thought, way too expensive too
            I was shocked that this product is 25.00, and not nearly as strong of a product I initially thought when I bought this. I guess only time will tell if this product really works. I usually won’t review a product for a really long time to see if it will hold up.
