For countertops? There is Clearseal and Vitramela. There is a guy here that has an epoxy, it is new, very much like Clearseal, but there are no fumes, Clearseal is a polyester resin.
I have been wondering if there is a solution somewhere short of these 1-2mm thick coatings that need to be sanded and polished and are very expensive for the customer. Like a high tech abrasion resistant strippable (or not) urethane. I have a message into Katrine at RJSC and wondering if they have a solution with some of their newer products, like Stonehardener 2 perhaps.
I know this is not ideal, but a lot of people don’t want to pay the $400m2 to do the thick coatings and there should be an alternative.
There is also a film that is applied like a window tint, easy to replace on an annual basis.
