Clear Penetrating Epoxy Sealer ™ – Why CPES? There is no substitute that performs as well. It is not cheap, but it is significantly cheaper than wood, repainting and maintenance generally. Do it once, do it right. Clear Penetrating Epoxy Sealer is an epoxy product, supplied as Part A and Part B in two tins. You must mix CPES before use. Mix it in a 1 to 1 ratio; however it is tolerant of minor mix errors. Mix by weight using 98 parts A by weight to 100 parts B for both Cold and Warm formula. Packaged between the two cans is a very comprehensive instruction leaflet. Please read this prior to use if you are unfamiliar with this product. You can order a copy of that instruction leaflet from us ‘How to restore wood booklet‘. There is a lot more, written by the inventor, that you can read about the science of clear penetrating epoxy sealer here.
