Smiths Warm CPES Epoxy

Smith's Clear Penetrating Epoxy Sealer (CPES) consists of a tough, flexible resin system in a solvent blend, and is used to aid in the restoration of rotted or deteriorated wood.

The epoxy resin system chemically adheres to the wood fibers and significantly strengthens them while allowing for normal expansion and contraction.

CPES is effective because it contains a special blend of solvents that penetrate deep into wood cellulose and fibers. When applied to rotten wood, Clear Penetrating Epoxy Sealer changes the cellulose (which the bacteria and fungi find easily digestible) into epoxy impregnated cellulose that resists fungi, while reinforcing and restoring the wood.

I purchased both the warm and cold version for a few projects, the penetration is excellent however it's so thin it does not provide any structural help even on lightly rotted wood. The scale (and cost) of the projects I had lead me to this product and if I had it to do over I would have used BoatLife's GitRot as I have before on other smaller projects. Even though its more expensive, it provides a better, stronger result. My best comparison would be that this product would make all the individual fibers strong in a rotted area, but still leaving them individual, requiring additional reinforcement(as they state in the directions) where GitRot makes all the rotted fibers a solid mass (it's a little thicker). The mass is much stronger than each fiber strengthened, and does not require as much or any additional reinforcement. GitRot penetrates well, and cures much faster than the Smith's

          Comments about Smith and Co Smiths Warm CPES Epoxy:

          Amazing product.....I purchased this for use with new construction with teak,mahogany and padouk to be used outdoors(partially shaded). I got extremely valuable(correct)advice from Peter , so don't be afraid to ask. It mixes very well and has the perfect amount of pot life if you stay within the temperature range of the product. Apply liberally ,but do not brush or roll back over it too much it will soak in. "USE IN A WELL VENTILATED AREA" but do not blow a fan directly on your work and try not to use in direct sunlight. You can use inexpensive brushes but not "cheap" ones and make sure that your roller covers are compatible with epoxies or they will turn to mush. Two coats was almost perfect(sanding between coats)but I used three just to make sure. This console is "beautiful" and sealed tight. There is no tinting or discoloration from the sealer so it will not effect the varnish or the natural color of the wood. This is the first time I have used a sealer on new wood prior to varnish and this product is awesome. Because I had so much success with it on new work I am going to experiment with it on a rot repair. I truly expect to get the same results.The pics are the console with the final application of the sealer prior to sanding and varnish.

            Use this in repairing a patio door that had some minor wood problems. It penetrated the wood and eliminated some leaks and dampness.

              Lots of opinions in several Hotrod magazines on how to best protect your truck boards exposed to weather elements. One of the best tests involve several different types of wood that had been protected by several name brand products. They were all tested outdoors exposted to the weather elements for a test period of five years. One of the best test results included a chemical composition identified in this products composition. This is why I chose it and feel comfortable applying several coats to the wood boards in my 1934 Ford Truck. Arizona's harsh weather is no longer as detrimental.

                      Worked great as a primer base on new Marine Grade Plywood along with several coats of Epifanes Clear Gloss Varnish. The process took a long time to complete due to the product setting up slower than what it said on the can.

                        I have used the product on a badly weathered front door, dry rot repairs, and as a sealer for stain. It works well and so far seems to stand up well. I like to spray finish things and wished you could spray this, but it goes on nicely for a brush-on application.

                        I use it on anything that I am concerned about a finish sticking to wood.

                          Using CPES Warm weather formula as a basecoat for varnish on new marine grade plywood. Should have used the cold weather formula because of the long curing time (3 days with this product). I was concerned about the pot life but it was not a factor with temps around 80 degrees F. The product was super easy to use, and is making a great base for varnish. The first coat or two of Epifanes took longer to cure than the can says but this had something to do with the ketones in the epoxy and is not a factor after the second coat of varnish.
