MAS Epoxy has changed their formulation somewhat to help with the tendency of the low viscosity resin to flow right onto the floor. The new material kicks off or seizes up sooner; it has saved us a lot of work in the last couple of months. Also, they now produce a thicker resin called FLAG (filleting, laminating, and gluing) that we have been using for filler coats on occasion.

Since their hardeners can be blended, we usually use 25% fast hardener to get the mix to seize up even sooner.
