PROGRESS PROFILES - PRODESO HEAT SYSTEM
Installing tiles on a cement based subfloor presents many challenges.
The following table illustrates the difference in thermal expansion between a cement subfloor
and the tiles surface…
TILE SURFACE MATERIAL THERMAL EXPANSION RATIO
Ceramic 6 times the thermal expansion of cement
Marble 7 times the thermal expansion of cement
Granite 9 times the thermal expansion of cement
CEMENT SUBFLOOR SETTING AND GROUTING MATERIALS
Adhesive to fix PRODESO HEAT MEMBRANE to subfloor Latex Modified Portland Cement Mortar (ANSI A118.11)
Adhesive to fix Tiles to PRODESO HEAT MEMBRANE Unmodified thin-set mortar - ( ANSI A118.1 )
GROUT Polymer-modified cement grout (ANSI A118.3 A118.6, A118.7, A118.8 )
CEMENT SUBFLOOR ANSI INSTALLATION SPECIFICATION
TILE FIXING ANSI (108.5)
GROUTING ANSI (A108.6 A108.9 A108.10)
• Cement Based Substrate must be compact and structurally sound
• Cracks and Fissure in the substrate need to present only longitudinal movement (NO VERTICAL MOVEMENT)
• Debris, dust, wax, grease, and oil residue must be removed or abraded/scored to offer better bond to the thin set.
• Minimum Tile Size 2” x 2” ( 50mm x 50mm )
• Seams, perimeters, and corners need to be sealed with Pro Band 150/250 when water migration is expected.
• Seams, perimeters, and corners need to be sealed with Pro Band 150/250 when a waterproof installation is necessary.
EXPANSION JOINTS:
PRODESO-HEAT does NOT eliminate the need for movement joints, including perimeter joints, within the tiled surface.
Movement joints must be installed in accordance with industry standards and norms TCNA EJ171, and TTMAC 301 MJ.
