PROGRESS PROFILES - PRODESO HEAT SYSTEM
• Minimum thickness for additional underlayment 3/8” or 10mm.
• Underlayment: APA C-C PLUGGED EXTERIOR
• Additional Underlayment is required for Joist/I-Beam /Floor Trusses spaced more than 19.2” for any type of tile.
• Additional Underlayment is required for all types of natural stone regardless of Joist/I beam/Floor trusses spacing.
• Underlayment 1/2” (13mm) or thinner: Fasteners Spacing 4” ( 102mm ) around the perimeter and 6” (152mm) in the field.
• Underlayment thicker than 1/2” (13mm): Fasteners spacing 6” (152mm ) around the perimeter and 6” in the field.
• 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.
SUBSTRATE PREPARATION
Wood panels need to be properly fastened and secured to framing structure.
Wood panels need to be clean of dust, residue, wax, oil, and grease.
Wood panels need to be levelled before the installation of PRODESO HEAT MEMBRANE.
Remove all exposed nails, screws, fasteners, and debris.
