DESCRIPTION
Permanent plastic mastic for sealing of cable penetrations and similar where pressurized water and moisture is present. It does not cure but remains a pliable mastic and can be reshaped at any time. It bonds excellent on both dry and wet substrates.

Application areas
Sealing of pipe and cable penetrations at basements and retaining walls. Can also be used to seal water break troughs.

Substrate
Dry, moist or wet. The substrate be free of grease, oil, tar and other contaminants which might affect the bonding adversely. Suitable substrates are concrete, brick work, mortars, plasters, and all other mineral construction materials, KB-FLEX 200 will also bond on ceramic, PVC, polyethylene and polypropylene.

Application
Heat KB-Flex 20° to 30° C in water before commencing work to reach suitable working consistency. The area to be treated must be thoroughly cleaned for dust, sand and other contaminants. Before applying KB-Flex 200 a barrier made of fast curing PU foam must be placed in 10 cm depth. The KB-Flex 200 cartridge s then placed in the gun and then pressed through the nozzle. After sealing cable penetrations, twist the cable and press the KBFlex 200 into the voids created by the flexing using a spatula firmly. For additional safety, we recommend to seal the end of the penetration duct with KB-Fix 5. If a new cable is to be added at a later stage, then remove the KBFix 5 plug, press the cable through the (existing) KB-Flex 200. Then press the KB-Flex 200 firmly into place using a spatula – if necessary some more KB-Flex 200 can be added.
