Adhesive cord of butyl rubber Ampacoll RS


Application tips:

Please note that gluing to wet or damp surfaces usually causes problems. The surface to be repaired must be dry, clean and free of dust and grease. Floors and edge/end joints on highly textured or dirty surfaces such as concrete or masonry should be primed with Ampacoll Primax. Sealing joints should not be more than 2/3 of the diameter of the cord used. This is achieved by leveling the corresponding part. When sealing the wall element to the concrete floor, after laying Ampacoll RS, 20 mm, the spacer can be left on the cord. This allows the wall element to move to a limited extent during the settlement phase.
