In these sensitive parts of the building, moisture can lead to severe damage to the entire building. Discoloration and tiles which are falling off the substrate are the first visible signs of such damages. Such rooms are waterproofed completely, in order to protect the entire building. The entire wall and floor area is seamlessly waterproofed. The waterproofing layer must be able to bridge possible cracks.
Only a few building elements are so constantly exposed to water as kitchens and bathrooms. In these cases a professional and crack bridging waterproofing material is required. Furthermore it must be stable enough so that tiles can be applied on top of it.
The KOSTER BD-System is a complete system for water proofing underneath tiles according to ETAG 022. The dry and stable substrate is primed with KOSTER BD 50 Primer. As a waterproofing layer KOSTER BD 50 is applied. In corners and connection areas the pre-formed waterproofing elements KOSTER BD Inside Corner, KOSTER BD Outside Corner, KOSTER BD Wall Sleeve and the KOSTER BD Floor Sleeve are embedded into the waterproofing layer. At wall / floor junctions and joints KOSTER BD Flex Tape K 120 is embedded. In areas where a reinforcement is embedded, movements won’t cause damage to the waterproofing material.
Always adhere to the specifications in the respective Technical Guidelines.
