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
