Application Instructions

Ensure the subfloor is clean, dry, and within the recommended temperature as specified by the floorcovering manufacturer and BS 5325. Apply ARDEX AF 835 evenly using a trowel and roller. Allow the adhesive to air for 20–35 minutes depending on substrate absorbency. The adhesive remains workable for up to 24 hours. Position flooring carefully and remove air pockets using a cork board or rubbing tool. Roll with a 68kg roller side to side and end to end. Wait before wet cleaning for at least 48 hours.

Priming

Priming is not required for most surfaces. On highly absorbent substrates, ARDEX P 51 diluted 1:3 with water can be applied to improve coverage and maintain working time.

Cleaning

Clean spills immediately with a damp cloth before the adhesive dries. Aggressive cleaning agents should only be used with the floorcovering manufacturer’s approval.

Storage & Safety

Store unopened tubs in a cool, dry place away from draughts. Follow standard hygiene practices. Avoid contact with skin and eyes. Wash with soap and water if contact occurs, and seek medical advice if ingested or exposed to eyes.
