Preparation of Substrate
Application surface must be dry, clean and clean off materials which prevent bonding, such as dust, oil, rust and remove loose pieces. If there is a water leakage it must be drained or properly plugged. Concrete surfaces must be saturated with water before application.
25 kg bag GRT 25 is poured slowly into 3 - 3,5 liters of water under low speed mixer for 3-4 minutes until obtaining homogenous mixture. Mixture should be applied on the surface immediately because of quick setting property. GRT 25 is only applied for filling applications as 10-50 mm thickness for each layer. If required more thickness surface, aggregate can be added to grout. If needed much more thickness extra aggregate should be added on the grout in ratio of 1/2 (1 cup aggregate / 2 cups powder). Vehicle traffic or machinery should be avoided until full cure occurs.
For 10 mm thickness 21 kg/m2 powder product needed. Recommended application thickness is min. 10 mm / max. 40 mm.
