CHIMEX 120 is a cement based, polymer reinforced, single component rigid waterproofing material used on concrete and cement based plasters. It can be applied from the inside and outside against leaking and non pressured surface water.
Preparation of Substrate
The application surface must be durable, clean and clean off materials which prevent bonding, such as dust, oil, rust and remove loose pieces. Big pores and cracks should be filled with REPAMERK 1 repair mortar. Application surface has to be wetted and then waited until it becomes wet/dry. Sharp tips and horizontal/vertical joints which are suitable cracking should be chamfered with REPAMERK 1 repair mortar or PH 127.
Application Method
4.5 L water is poured into a clean container and then slowly added 20 kg CHIMEX 120. Continue mixing until obtaining a homogenous mixture without any agglomerate (approximately 3-5 minutes). Mixture should be applied with a brush as 2 or 3 layers. Brush application direction for each layer must be perpendicular to each other. Prepared mixture have to be used within 2 hours. The surfaces that will be walked on have to be coated by grout or ceramic.
For first layer - 1,50 kg/m2 powder.
For second layer - 1,30 kg/m2 powder
For third layer - 1,20 kg/m2 powder
Recommended at least 2 coats application, if needed 3 coats might be applied. Product should be applied as maximum 2 mm wet film thickness in single layer.
