Cut your first border tile to size. Because this tile will fit into a corner, it must take into consideration the dimensions of border tiles on both short and long sides of the room. For example, if your border tile on the long side of the room turns out to be 10" and on the short side of the room only 9", the corner tile should be cut along two sides to make it 10" by 9", allowing all other border tiles on both short and long sides of the room to line up properly with your full-size tiles.
In cutting these first border tiles, cut off the side without the wide stapling edge. The wide stapling flange must be exposed so the tongue of the next tile can fit into the groove of the tile already in place, guaranteeing a solid fit.
Staple the tile in place, with three staples on the edge that is completely against a furring strip and staples in to corner only on the other edge. (See Fig. 11).
Place several border tiles in position along each edge, and then fill in between them with your full-size tiles.
After you have worked your way across to the opposite wall, you must measure and fit each tile carefully on the opposite border.
Installation of a border molding completes the job, and also serves to hold the final border tiles in place where there is no flange left for stapling. At the border, where your access to the stapling area is limited, you can attach the nails with small broad-headed nails, positioned as close to the wall as possible so the finish molding will conceal them. (See Fig. 6).
