Find the lowest point on the floor line. Make a mark one tile height from the floor.
Nail a battern with a true edge on the mark. Check with spirit level to determine horizontal.
Set out a row of tiles across the wall and adjust so that equal cuts can be made in the corners. Mark the battern where the first tile is to go.
Use the straight edge of a notched trowel to spread adhesive on wall.
Start tiling at the mark on battern, placing tiles horizontally. Remove tile spacers before grouting.
Check tiling regularly with a spirit level to keep work straight. Ensure that good contact with the adhesive is made.
After adhesive has set, remove battern and fill in bottom row.
In a horizontal direction, notch the adhesive with the appropriate notched trowel.
