Bostik STIX A640 15Kg is a high performance, solvent-free, pressure sensitive acrylic adhesive, which is ideal for bonding PVC sheet and tile coverings.
Bostik STIX A640 15Kg adhesive has been specially formulated to give a high initial tack and excellent bond strength, and dries to form a permanently tacky film. It offers high performance as either a wet or dry stick adhesive. Bostik A640 provides a smooth, easy application with excellent workability, which makes it ideal for use with all types of PVC floorcoverings. It can be applied to smoothing compounds, concrete, sand/cement screeds, flooring grade plywood, chipboard, hardboard and screed boards.
Wet stick Applications:
Apply the adhesive to the substrate using the appropriate trowel size. Allow the adhesive to air for 10-15 minutes. Once the adhesive has sufficiently aired to form a tacky film over the adhesive ridges, place the flooring into the adhesive bed. Immediately roll the flooring using a 68kg heavy roller to dispel any trapped air and ensure there is a transfer of adhesive onto the backing of the floor covering. After 30 minutes, roll again.
Dry stick Applications:
Apply the adhesive to the substrate using the appropriate trowel size. Allow the adhesive to air until it becomes fully clear 30-60 minutes. Once the adhesive has sufficiently aired to form a clear and permanently tacky film, place the flooring into the adhesive bed. Immediately roll the flooring using a 68kg roller to dispel any trapped air. After 30 minutes, roll again.
To minimise the effect of adhesive serrations showing through thin floor coverings, a roller prewetted with adhesive can be used to flatten what has been applied to the subfloor, ensuring that none of the adhesive applied is removed. This creates a uniform appearance and maximises surface contact with the floor covering. Place the floor covering immediately after application of the adhesive.
