PLACING
A. Spread topping mixture evenly over prepared base to the required elevation and strikeoff.
Use highway straightedge, bull float, or darby to level surface. After the topping has stiffened
sufficiently to permit the operation, and water sheen has disappeared, float the surface at
least twice to a uniform sandy texture. Restraighten where necessary with highway
straightedge. The surface shall achieve an FF20/FL17 tolerance when tested in accordance
with ASTM E 1155. Uniformly slope surface to drains.
1. Where joints are required, construct to match and coincide with joints in base slab.
Provide other joints as shown.
B. After floating, begin first trowel finish operation using power driven trowels. Continue
troweling until surface is ready to receive final troweling. Begin final troweling when a ringing
sound is produce as trowel is moved over surface.
C. Continue final trowel operation to produce finished surface free of trowel marks, uniform in
texture and appearance, achieving an FF25/FL20 when tested in accordance with ASTM E
1155.
3.03
CURING AND PROTECTION
A. Cure and protect topping applications and finishes as specified by the topping manufacturer.
3.04
PERFORMANCES
A. Failure of concrete topping to bond to substrate (as evidenced by a hollow sound when
tapped), or disintegration or other failure of topping to perform as a floor finish, will be
considered failure of materials and workmanship. Repair or replace toppings in areas of such
failures, as directed.
