Installation with swelling tape adhesive:
The substrate must be clean, dry, and free of loose particles.
Apply the swelling tape adhesive in the centre of the joint in a uniform bead (width 8-10 mm) out of the cartridge onto the surface.
The subsequent concrete covering must be at least 8 cm on all sides.
Once the swelling tape adhesive has been applied in the centre of the joint, the MASTERSTOP bentonite swelling tape is placed on the adhesive and gently pressed on, moving it slightly back and forth, crosswise to the longitudinal axis.
When the tape is fixed, the adhesive should slightly ooze out on both sides.
This guarantees a complete fixation.
Ready for use after 4 – 6 hours (depending on weather conditions)
Installation with swelling tape grid:
The substrate must be clean, dry, and free of loose particles.
Place the MASTERSTOP bentonite swelling tape in the centre of the joint.
The subsequent concrete covering should be at least 8 cm on all sides.
Position the swelling tape correctly.
Push the fixing grid firmly onto the MASTERSTOP bentonite swelling tape.
Fasten using corresponding nails and either by hand or mechanically using a bolt-firing tool.
The distance between nails must not exceed 20 cm in the longitudinal direction of the swelling tape.
Both, straight and angle joints need to be butt jointed.
The joint areas must be form-fit in order to avoid any discontinuity in the system.
In the case of butt joints in the straight line and the use of swelling tape grids, the joints of swelling tape and swelling tape grid should be offset.
