Smiths Cold 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.

After buying first sailboat (didn't have a eval. ran on it,which I recommend first) I got it home and found out it had a wet core and it was exacerbating the spidercracking over enter deck. The instructions on Jamestown on how to use this product were excellent, and I followed to a "T". After sealing the deck holes (follow instructions) I found only 2 problems. It is better to wait until late spring/early summer to do this project (rains were a problem this year.) Other problem was that no matter how good a job you do, there will be some seapage into cabin compartment so you need to be around the boat closely to get this up before it hardens in the interior (mainly around seals on windows.) I used Interlux epoxy primer and polyurethane paints to finish deck. Had my ASA instructor tell me that the job was strong after testing it under foot. End of project, I strongly recommend this process.

I used this as a primer sealer on teak in preparation for varnish and I worked out of doors. Due to the long setup time the weather is critical. Dew or rain could ruin your results. Using this outdoors in springtime New England could be very problematic. I managed it but not without a lot of worry! In a shop setting or under cover I think this would be an excellent product for sealing prior to varnish.

    Comments about Smith and Co Smiths Cold CPES Epoxy:

    I use this product professionally in house restoration. If an area of rot isn't sufficiently structurally weak, I can save the piece and maintain the historic integrity of the building. Some areas are simply too expensive to replace considering that the rotten area isn't large enough to pose structural problems unless the rot isn't stopped chemically. This product does that.

    Comments about Smith and Co Smiths Cold CPES Epoxy:

    I use this product in lieu of red lead when working below the waterline, i also use this extensively on old house restoration and stabilization of exterior components that have already been stripped and sanded to finish as a ultimate wood sealer before painting.The wicking action displaces the air in the wood cells so that no water can go in.i seal all grain with this stuff with great results and lightly sand with 220 to remove raised grain.

    Comments about Smith and Co Smiths Cold CPES Epoxy:

    I have to say that I rodered this product beczuse it is the only product out there that will truthfully protect yoru wood idefinitely. Others may make a claim that theirs works better. Nothing works better than basically turning wood into fiberglass. Unfortunately if you live in Canada the shipping charges are ridonculous!!! A product I bought for $41.00 American came otu to $121.00 American! Luckily (or unluckily) I passd this cost onto my client. They were satisfied with the results. If you can find no better distributor in Canadathen you will have to bite the proverbial bullet and have yoru wallet amputated.

    Comments about Smith and Co Smiths Cold CPES Epoxy:

    I used this on a bird bath made out of redwood. The previous attempt at making the bird bath had trouble with the lifespan of the varnish and squirrels chewing the wood. Hopefully the CPES will help the varnish adhere and prove distasteful for the squirrels.
    I used about 6 oz. to treat about 3-4 bd/f.

        Comments about Smith and Co Smiths Cold CPES Epoxy:

        This stuff is like liquid epoxy after you mix it. Penetrates both new and old wood. I had the entire interior of my Cuddy Cabin recovered and treated all of the the wood backing with CPES. After 28 years of being in the desert heat you can imagine how dry and brittle the wood had become. CPES made the wood stronger and kinda like a plastic because the wood absorbed so much CPES. I also treated the new 2 X 6's for the trailer after belt sanding with 60 grit to open the pores. Sealed cracks in the polyester resin that coated the wood floor of the boat then laid another layer of fiberglass. Uncertain about the condition of the the bilge at midships I poured CPES in the bow section of the bilge until it came out in the stern to seal any potential exposed wood inside the hull bottom I was unable to see. Pending upon your project I suggest ordering more then you think you need. You'll find Many Other places to apply it.

              It works as advertised. I used it on a wooden dinghy that leaked at the chines. I used it with some wicking, and saturated the inside and outside of the joint. Took some time to do it properly, but it secured virtually all of the leaks.
