pretty exclusive to stamped concrete. We measured things with a tape measure and "1/4 in." was a really small measurement. After getting into concrete coatings, however, I started to realize that things are measured in Mils not inches and that 1/4 in. would equal 250 mils (an incredibly thick coating). Most of the coatings systems that I have dealt with are applied anywhere between 6-30 mils. We would consider anything over 15 mils a high-build coating. Not all concrete coatings will be suitable to build up that thick in one coat. Polyaspartic, for example, should never exceed 8 mils per coat. The coating of choice in most highbuild situations will be 100% solids epoxy. This stuff has been around for a long time and is still one of the most
