No primer is required when applying BeSealed swellable paste on a clean concrete surface.
For optimal adhesion, a stable, clean, dust, oil, and fat-free surface is recommended. If required, cleaning with acetone or isopropanol is recommended.
Optimal fixation is achieved when the full contact area of the water-swellable sealing bar is covered with paste.
After application of the paste, the water-swellable sealing bar needs to be pressed down to ensure full contact with the paste underneath and to achieve optimal adhesion
Adhesive bead extruded, fully immersed in water at 23°C.
BeSealed water swellable paste is a high-quality, one-component polyurethane adhesive which swells in contact with water. Upon contact with water, the paste can expand up to 450% of its original volume. It can be applied both for Polybar+ and Bentobar+.
