Љ DensShield can be used as a tile substrate in
floor tile applications for residential and light commercial
use as defined in the Handbook for Ceramic Tile Installation,
published by the Tile Council of North America.
Laminate DensShield panels, coated side up, to subfloor
using a latex portland cement mortar liberally applied
with a
1 ⁄

Љ square-tooth notched trowel.
Embed DensShield into mortar while still pliant (do not
exceed open time). Butt DensShield panels tightly together.
Stagger DensShield joints over subfloor joints. Fasten
DensShield panels to subfloor. Avoid nailing into floor
joists on new construction to prevent nail pop-ups. Space
fasteners no greater than 8 Љ o.c. in both directions. Drive
fasteners flush with the surface— do not countersink. Apply
2Љ 10 x 10 fiberglass mesh tape over joints. Embed with
latex portland cement mortar.
Apply flooring-grade tile with latex portland cement
mortar. Full-thickness thresholds should be used and
butted against the DensShield panels flush with the tile
surface. Important: For residential applications, use a
2Љ x 2Љ or larger floor-grade tile.
• Use latex portland cement floor grout (ANSI A118.6).
• DensShield tile backer is not to be used in conjunction
with passive solar heat systems or in heated flooring
systems that are consistently over 120˚ F.
• DensShield is not to be used in shower floors or curbs.
