Installation steps

1
PLUMB WALLS: FULL-BED METHOD
Where walls are plumb and free of excess mortar, trowel a suitable tile adhesive onto the wall or the back of the board using a notched trowel. Press the board firmly into place and check for full, even adhesive contact.

OUT-OF-PLUMB WALLS: DOT AND DAB
For walls that are out of plumb, or where excess mortar prevents full-bed fixing, apply continuous adhesive around every board edge with enough adhesive dabs through the field. Where required, provide additional support using Thermasheet knock-in washer fixings.
