ANHYDRITE BASED UNDERLAYMENT ANSI INSTALLATION SPECIFICATION
TILE FIXING ANSI (108.5)
GROUTING ANSI (A108.6 A108.9 A108.10)
Anhydrite based underlayment must be installed over a compact and structurally sound subfloor
• Gypsum underlayment maxium relative humidity must be 2% or less.
• Follow gypsum manufacturer installation instructions, requirements and warnings.
• Debris dust 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.
• 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.
