This Professional screeding float or trowel, RWS152 is used by the carpet fitter or floor layer when repairs to the concrete sub floor are required. Once the screed has been laid, the surface of the screed needs to be smooth. This is acheived with the use of the screeding float / trowel. The screed trowel is made from sprung steel and has a rubber handle. Once the screed has set, any surface imperfections that may show through the flooring should be removed from the screed by use of a carborundum stone (RWS071). Remember any imperfections may cause the flooring to fail and may be so visible that you are called back for remedial work which is expensive and will not get you a recommendation. Remember, do it once and do it right, be professional.
