Koster KD System

A basement waterproofing system installed from the inside when water is actively entering the building. Koster KD 2 Blitz powder is applied directly by hand to the active leakage. The powder reacts within a few seconds and forms a waterproof mortar.

When the active leakages are stopped, the waterproofing layer of Koster KD 1 Base, Koster KD Blitz powder and Koster KD 3 Sealer can be applied. The material is applied to substrates that have to be sound and solid as well as free of bond inhibiting agents. Older plaster coats have to be removed and joints raked out and all loose particles have to be removed. Generally, the substrate is primed by pre-wetting. Repairs and the installation of the fillet at the wall-floor junction are done with Koster Repair Mortar Plus.

KÖSTER KD 1 Base is applied as the waterproofing layer and is brushed onto the substrate. Koster KD 2 Blitz Powder is rubbed onto the still wet surface, immediately creating a dry waterproofed layer. To harden and to strengthen this layer the third part of the system, Koster KD 3 Sealer, is applied. To waterproof the basement completely another two layers of Koster KD 1 Base is applied over the first layer.
