EPL technology comes from extensive research into the causes of outdoor wood coating failure. Wood is basically a biodegradable sponge. CCA and ACQ take care of the bio problems. EPL addresses the wood's surface problems. The key properties of expansion, contraction and rebonding of the EPL film are essential. EPL will heal itself (reform and rebond even after it looks like it has failed). EPL film will do this over and over again until the wood eventually remains dry, even after a couple of seasons. You need to provide patience (until warm, dry weather returns) and persistence (recoat as necessary) to get there.

Sealers and stains consist of oils and pigments that soak into the wood. Paints consist of binder and pigment that lay on the surface of the wood. EPL is a cross between these extremes that will absorb deep into the wood while leaving a significant plastic protection on the surface.

Plastic wearlayers vary widely in longevity. It always depends on thickness of the film and adhesion. The best performance, in our studies comes when you achieve about 4 mils. EPL delivers about 1 mil of plastic with each application. So start now (2 coats the first year and 1 each year after) and you can have plastic coated pressure treated wood on your deck or playset.

The ideal situation is older cca treated wood that has been cleaned with a strong power wash. The surface will become rough and splintered. This presents the best surface for EPL application (and the worst for stains or sealants). Adhesion is promoted and the EPL covers the splinters.

EPL is a milky white liquid that dries clear in 15 minutes and is unlike any outdoor wood treatment found in home centers. EPL will preserve the natural or stained color of your outdoor wood while protecting kids from splinters.
