Product Overview

For 18-years, Post Protector has provided simple, slide-on barrier protection for in-ground posts and we are continuing the exceptional quality with our Skirt-Board Protector. 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. Moisture, oxygen and suitable temperature is what really enables 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. Skirt Board Protector becomes the perfect complement to the pressure treated (or cedar) post by simply providing a physical barrier isolating the base board of your structure so the wood-destroying organisms have no access to the wood fibers. See Instructional PDF below for installation video links.
