Investigation results of the drying rate of the selected protective water coatings are presented in the paper. The water coating WC-R was subjected to examinations. The drying kinetics of this coating was determined. The coating was deposited on cores of the moulding sand of the matrix grain size being: dL= 0.20 mm; 0.24 mm; 0.34 mm. In addition, the kinetics of the coating drying process was determined for three conventional viscosities (15s; 22s; 34s). The coating viscosity was estimated by means of the Ford 4mm cup. Drying rates of the protective coating were examined by using the gravimetric technique (weight). Measurements were carried out in a continuous way under controlled conditions: constant ambient temperature and air humidity.
