• For best results a minimum temperature of 18C should be maintained for the installation.
• An appropriate V notched trowel should be used to apply the adhesive evenly.
• For vinyl and other smooth backed floorcoverings, a 1.5mm x 5.0mm or A2 trowel is recommended, whilst a 2.0mm x 6.0mm or B1 trowel should be selected for floorcoverings with a more profiled back. Trowels should be cleaned after use withwater whilst the adhesive is still wet. Apply the adhesive evenly to an area of such a size that the floorcovering can be laid whilst the adhesive is receptive and gives good transfer. On absorbent surfaces lay the floorcovering immediately or in the case of tiles after 10-15 minutes (this reduces the slip). On non-absorbent surfaces allow the adhesive to develop a tack or, for sheet goods, employ a “double drop” technique to reduce the waiting time before laying. It is recommended that the adhesive bonding the underlayment to the subfloor should be allowed to cure before bonding the final floor finish to the underlayment, ideally the underlayment should be left overnight and the final floor finish applied the following day.
• To reduce the effect of shadowing on some vinyl’s, it is recommended that the adhesive is smoothed out whilst wet with a paint roller that has been pre-wetted with adhesive. Once installation area is laid, roll immediately in two directions (at right angles to each other) with a 68kg roller (on carpets use a weighted glider). This is to remove any trapped air and ensure good all-over adhesive contact.
• A second rolling (or gliding) is recommended approximately 1 hour later to ensure a strong bond is established.
