The product I was referring to is 100% solids, self leving epoxy. It is first squeeged out. "Back rolling" is done in one direction to help the epoxy flow and level out, providing a uniform appearance. Do not over roll these products, as it may introduce air into the coating, which you do not want. You may need to wear "spikes" (golf shoes w/ spikes)while applying a coating like this. This way you will be able to walk on the coating without harming it- Be careful- slippery when wet.
