Waterproofing of balconies and terraces with cold applied self adhesive membranes

A fast and easy method for waterproofing balconies and terraces is using the cold-applied self-adhesive KOSTER KSK waterproofing membranes.

The solid and clean concrete substrate is primed with KOSTER KBE Liquid Film, which provides an excellent bond between the concrete and waterproofing layer.

A fillet at the wall/floor junction can be easily installed by using the KOSTER KSK Triangular Ribbon: Remove the protective foil and press into the primed corner. Alternatively, before priming the substrate a fillet of KOSTER Repair Mortar Plus is applied.

The standard area waterproofing is done with KOSTER KSK SY 15. The waterproofing membranes are bonded onto the prepared substrate and overlapped at least 4 inches on each side.

If the waterproofing is applied vertically onto a wall, the waterproofing membrane is mechanically fixed. Connections and overlaps are sealed with KOSTER KBE Liquid Film.

A topping protects the waterproofing against mechanical damage. A gliding layer consisting of two layers of plastic sheeting is installed under the topping.

Always adhere to the specifications in the respective Technical Guidelines.
