These two laminated beam sections were adjacent slices, cut side-by-side and one treated, so you can compare the almost identical wood before and after impregation. The fungi that causes rot leave an abnormal porosity in apparently sound wood near the decay.
Rotten wood is clearly visible. The rot actually extends into wood that looks good. This is why rot starts up again behind conventional repairs with other products.
The slice on the right was treated with Clear Penetrating Epoxy Sealer dyed blue, so that regions of abnormal porosity (rot) would be visible after impregnation
The Wood was placed in a shallow tray
and the liquid wicked up into the wood. In only a few minutes, in regions where thefungi had eaten the wood, the dyed resin was now visible. CPES resin impregnates deteriorated wood much more than sound wood, because it has more porosity.
These regions are now impregnated with
a highly rot-resistant, water repellent resin. Useful mechanical properties are also restored. This treatment improves the ability of the wood to resist further deterioration. This is the first step in the restoration process. When finally painted, the impregnating resin glues the paints to the wood, so it sticks better and last longer.
There are epoxys manufactured for fiberglass layup, for restoring automobiles, fast cure glues and others. They were manufactured to be used for specific applications. CPES was also manufactured for specific applications. Every product will do the job for the applications intended.
CPES is a two-component product, made from largely the same oils and resins as are in wood. This product was manufactured for the following application.
Restoration of deteriorated wood, CPES inpregnates wood by a capillary action. It does not require the use of hyprodermic needles for penetration. Application is by brush, roller or low-pressure sprayer. CPES contains solvents, which dissolve the saps and oils in wood. Restoration and reinforcement of the wood is accomplished without changing the natural flexibility of the wood.
How does CPES mix with moisture and dissolve it from wood?
Epoxy resin systems do not readily dissolve water, but CPES contains a feature which which dissolves not only the moisture in wood but also the saps and oils. It is quite one thing to dissolve oils in wood but quite another thing to dissolve saps & moisture. The product was orginally designed for the marine industry in the restoration of boat hulls. Clear Penetrating Epoxy Sealer(CPES) will greatly reduce the infusion of water, reduce expansion and contraction and still allow the wood to breath as much as it needs to. The wood is now stablized.
How does CPES make coatings stick and last longer?
In order to obtain a good bond between wood and any paint or filler, the fibers on the wood surface must be strongly bonded to each other and to the filler or coating. The bond must be very flexible since wood expands & contracts as the humidity in the air changes with the weather and the seasons of the year. All Epoxy products are not the same. Most are made from petrochemicals. CPES is made substantially from wood
itself and these particular resins when cured will be comparable to the orginal wood. This is the reason why it sticks so well to wood and why topcoats stick so well to treated wood. Topcoats are actually sticking to epoxy-impregnated wood fibers glued down into the bulk of the wood by CPES. CPES is very unique in that its formulation can do all these things.
After soaking for a couple of hours in Clear Penetrating Epoxy Sealer, not only can you see CPES working its way up the sides of the wood but a view from the top lets you easily see how Clear Penetrating Epoxy Sealer is working its way through the wood. This is why it so effective at solving rot problems in areas that you cannot see, and hard to access. Monies and time are saved because the harder it is to access an area for repair the more expensive the repair will be due to time and materials. This product does the work for you.
