No- the apoxy has "give". Some restaurants coat their tables with it. It CAN scratch, so no cutting directly on the countertops! We will probably have to re-apoxy the "high traffic" areas in 2 years, but no big whoop. It only takes a few days to dry--so we will probably do it when we re-seal the tile floors and then go on vacation.
OR--we may be tired of it by then. We still have all the forms, so maybe we will do something different. Having done it once, and having a big open space to keep the drying tops in (the shed or garage) makes the WHOLE thing less of a hassle. I doubt this house will ever be finished. But what then? Get llamas as a new hobby?
I looked at the Cheng technique extensively, and considered staining with the stencils. Alas, I was voted down by the menfolk, but still fancied it up.
