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. Roughen the surfaces you want to bond with sandpaper or by carefully draw-filing the areas. Remove dust, grease, and dirt from the surfaces. If the wood is old, porous or has suffered significant exposure to sunlight or the elements, it is normally safest to halve these coverage figures (ie you will use double the amount required for new timber). CPES as a surface finish for interior timbers I will often harden wood like this as it can make the restoration of a profile far easier than removing the dust and then filling, even though it is a little more expensive. The solvents can take a long time to evaporate from timber in this state if the sections are large. Evaluation by Trial The ratio of base to curing agent controls the performance properties of Arbokol 1025 SP and tins are filled off to an exact mixing ratio. It is vital therefore that the whole contents of the curing agent tin are added to the base tin. The 2 components must be thoroughly mixed to ensure complete homogeneity (Spiral “pigtail” mixing equipment is recommended). Application

Should you wish to mix Smiths CPES by weight the ratio is 98 parts of A to 100 parts of B. Smiths Clear Penetrating Epoxy Sealer is very forgiving of minor mix errors and the only real penalty will be more of one can left than the other when you have finished the job.

CPES use on new or sound timber is far easier to estimate. As all timber varies these figures are only estimates: 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. Smiths CPES comes in two tins labelled A and B. Mix the two parts 1 part to 1 part by volume prior to use. I find the easiest way is to take a parallel sided jam jar, decide how much you wish to mix, and make marks to suit, say at 4 and 8cm up from the base on the jar. Pour to the marks, and shake thoroughly.
