INSTALLATION FOR TILE
Layout of the Room for Squarely Laid Fields
To square the area to be covered, first find the center of one end of the main rectangle. Locate the same
point at the other end wall. Snap a chalk line between these points to mark the center line on the floor.
Then measure along this center line to find the middle of the room.
Fig. 1
At the center point, mark off a line across the room at exactly right angles to the first line. This may be
accomplished by the 3-4-5- triangle method as shown in Figure 1. Then measure 4 feet toward each
side wall from the center point. Then measure 3 feet from the center point along the longer line, measure
exactly 5 feet from the 3 foot mark on the center line to the 4 foot mark on the crossline. If the 5 foot
measurements do not come out exactly 5 feet, the center crossing lines are not at a true right angle. For
large rooms, multiples of the above dimensions may be used to obtain greater accuracy. (6-8-10 or 9-12-
15, etc.)
Dry-lay a row of tiles from the center line to the side wall to determine the space left for the borders. If the
resulting border is too small, move the starting point over a half tile width so that it straddles the center
line. Repeat the same procedure lengthwise of the room. (This can readily be figured out from the room
dimensions without putting down the tiles if desired.)
Fig. 2
If it is decided to have the center row of tiles straddle either or both of the center lines, additional
guidelines should be snapped on the floor ½ tiles width on one side of either or both center lines as
required. (See Figure 2)
After the border widths have been determined and the center starting lines have been snapped spread
the recommended adhesive on the center lines leaving portions of the lines at center and near each wall
uncovered as shown in Figure 3.
Fig. 3
Spread the adhesive over one-half the area and after it is ready, start laying tile from the right angle
formed in the center of the room by center lines. Lay toward the two corners of the room as shown.
Always refer to your guide lines as you progress with laying tile so that any mistake can be corrected
before it is too late. Sometimes it’s necessary to compromise on the rightness of joints to make
allowances for unevenness or waves of the subfloor. Take care to place tile as accurately as possible
without sliding them into place. If grouting tile please leave appropriate spacer between tiles and follow
instruction on page eight for use of Array-Grout.
IMPORTANT: All flooring must by rolled with a minimum 100-lb roller after installation. Use a hand roller in
areas not reached with a 100-lb. roller.
