Installation Instructions

Basic Square Layouts
• Place a mark in the center of the oor at each end of the room.
(AB) Then snap a chalk line between the marks.
• Find the center of the line and snap a second chalk line at a right
angle (CD); use the 3’, 4’, 5’ method to form a right angle (Fig. 6).
• Make a dry layout in one quadrant along the center and perpendicular
chalk lines. Remember to allow the desired grout line space between
the tiles. A story pole (board marked with tile dimensions, including
grout line width) can also be used in place of a dry layout.
• Measure the distance between the last whole tile and the wall. If the
distance is less than half a tile, snap a new chalk line one-half the
dimension of a full tile away from the original chalk line (Fig. 7).
This will provide a balanced layout with larger cut tile at the border.
• When installing DuraCeramic Dimensions in a 1/2 drop layout or a 1/3
drop layout it will be necessary to snap additional chalklines for starting
locations. First complete a basic square layout with center and perpen-
dicular lines. Normally the tiles are laid with the long dimension parallel
with the long dimension of the room.
1/2 Drop Layout
• Snap a second perpendicular chalkline 12" away from the rst
perpendicular line (Fig. 8). Complete a dry layout in the rst 2 rows
starting from the perpendicular chalklines. If the border tile
in either row is less than 6", adjust the perpendicular lines 6" in
either direction.
1/3 Drop Layout
• Snap two additional chalklines, one 8" and the other 16" away from
the center perpendicular line (Fig. 9). Complete a dry layout in the rst
3 rows starting from the center perpendicular chalkline. If the border
tile in any of the 3 rows is less than 4", adjust all three perpendicular
lines 4" in either direction.
Note: Chalk lines can be easily removed or difcult to see after applying
adhesive over some subfloor surfaces like old flooring and concrete. To
avoid loosing the lines, mark the subfloor with a pencil and a straightedge,
directly over the chalk lines.
Adhesive Application
Congoleum DS100 DuraSet Adhesive is a pressure-sensitive adhesive
that must be allowed to dry completely to a tack before setting tiles.
• Apply the adhesive with the trowel blade adaptor included with
the adhesive. The recommended trowel notch size is 1/16" wide,
1/32" deep, 1/32" apart.
• Spread the adhesive over one-half of the suboor and a few inches
beyond the center chalk line.
• Allow the adhesive to dry completely to a tack before installing the tile.
Normal dry to tack time is about 45 to 60 minutes; longer in cool or
humid conditions. The adhesive will turn from light blue to clear when
tacky dry and will not transfer to the finger when firmly touched. Do
not use fans to accelerate adhesive drying time. Fan drying can cause
the top surface of the adhesive to dry prematurely, trapping residual
moisture in and preventing the adhesive from fully curing.
• Tile must be installed within 12 hours after adhesive turns clear.
