Fosroc Preco RWB

Surface revealing liquid for exposed aggregate finish on fresh concrete.

Preco RWB

Preco RWB is used to reveal aggregate in freshly placed horizontal concrete to produce an exposed aggregate finish, or a key for subsequent pours or renders.

Typical Applications

For exposed aggregate finish, or a key for subsequent pours or renders, e.g. floors, precast walls and slabs, paving

Advantages

Preco RWB provides uniform and controlled depth of retardation.
Preco RWB treated surfaces are normally readily revealed and cleaned by careful jet hosing or stiff brooming
Surfaces treated with Preco RWB provide an excellent key for bonding subsequent renders or concrete, without the need for hacking, or mechanical scabbling
Depth of reveal for various sized aggregate can be readily controlled
Economical and simple method of horizontal concrete surface revealing
Flexible time factor – up to 24 hours under normal application usage
Less labour time necessary to obtain required face up finishes
