Substrate preparation for Koster Waterproofing Sealing Compound KB Flex 200 Sealing Paste

The substrate can be dry, moist or wet. The substrate must be free of grease, tar and oil as well as free of loose particles. Suitable substrates are: concrete, masonry, mortar, plaster and all other mineral construction materials. Koster KB-Flex® 200 will also bond on ceramic, PVC, polyethylene and polypropylene.

Application

Prior to application, the cartridge containing Koster KB-Flex®200 is put into warm water and thus heated to approx. 300C. This ensures that the material will have an optimal consistency for application. The feedthrough must be thoroughly cleaned from the inside so that it is free of dust, sand and other loose parts.

The waterproofing made of Koster KB-Flex® 200 must be dimensioned so that the ratio of the width to the diameter of the installed material is not below 1.5 to 1. The maximum diameter of the waterproofing is 300 mm.

Before applying Koster KB-Flex® 200, a securing block is installed in the feedthrough at a depth of 10 cm using a customary 2C PU-foam. The Koster  KB-Flex® 200 cartridge is then placed in the gun and the material is pressed into the feedthrough from back to front utilizing the flexible nozzle so that the resulting layer thickness is at least 8 cm.

After sealing cable feedthroughs, jiggle the cables and press Koster KB-Flex® 200 into potential voids created by the jiggling. Make sure that the cable is lying free of tension after finishing the sealing. Finally, the sealing compound, laying back approx. 1 cm, is pressed in well and smoothed with a metal spatula. As an additional safeguard, the mouth of the feedthrough is closed with Koster KB-Fix 5.

If a new cable is to be installed in this feedthrough later on, then the KB-Fix 5 plug must be removed first. After that, the (new) cable is pushed through the (existing) Koster KB-Flex® 200. Finally, if necessary, the feedthrough is resealed by pressing in additional KosterKB-Flex® 200.
