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 KÖSTER BD-System is a complete system for waterproofing underneath tiles according to ETAG 022. The dry and stable substrate is primed with KÖSTER BD 50 Primer. As a waterproofing layer KÖSTER BD 50 is applied. In corners and connection areas the pre-formed waterproofing elements KÖSTER BD Inside Corner, KÖSTER BD Outside Corner, KÖSTER BD Wall Sleeve and the KÖSTER BD Floor Sleeve are embedded into the waterproofing layer. At wall / floor junctions and joints KÖSTER 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.
