Waterproofing of balconies and terraces with mineral based waterproofing systems

The cementitious waterproofing of balconies and terraces is carried out with crack bridging KOSTER NB Elastic (white or grey). This waterproofing is resistant to foot traffic and can be covered with tiles. It also bonds to damp substrates.

Before installing the waterproofing, the substrate is hardened and prepared with the primer KOSTER Polysil TG 500. Fillets are installed with KOSTER Repair Mortar Plus. At wall/floor junctions and in all areas in danger of cracking, KOSTER Glass Fiber Mesh is embedded into the fresh first waterproofing layer.

Concrete repair work is done with KOSTER Betomor Multi A. The concrete surface must be mechanically cleaned and a solid substrate achieved. Reinforcement steel must be thoroughly cleaned of rust.

Minor damages in the concrete surface can be levelled with KOSTER C-Coat, and painting done with KOSTER Silicone Paint White.

Always adhere to the specifications in the respective Technical Guidelines.
