❚　Application

After the concrete has been screed, consolidate and further level by bull float and any free water has evaporated or been removed, the surface should be floated by hand or bull floated. Immediately following this floating operation, shake the B-VER Natural Grey Hardener by hand over the surface.

The first application of the B-VER Natural Grey Hardener should use about 2/3 of the total amount needed. The dry shake material will absorb some moisture from the freshly prepared concrete and should then be thoroughly floated into the surface, preferably by a bull float. Immediately after this, the remainder of the specified amount of the B-VER Natural Grey Hardener should be distributed evenly over the surface at right angles to the previous application. This should be thoroughly floated. A mechanical power float machine should be used to produce a smooth, dense and level concrete surface. Final troweling is best done by hand.
