Bostik STIX A640 Pressure Sensitive 15Kg

Description

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.

Roller Application:

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.
