Performance: ASTM C627 Standard test method or evaluating ceramic floor-tile installation systems using the Robinson-type floor tester.Properly primed, may require plastic lath. Gypsum: Minimum thickness is 3/4" (19 mm) above floor-warming systems.Organic: No TCNA recommendations for use with radiant-heating systems.ANSI A118.1 ( limited to TCNA RH135-09, over backer board). Cementitious: Latex-Portland cement meeting ANSI A118.4 and ANSI A118.11.Concrete: Properly cured, on slab-on-grade, no bending or stresses, no moisture intrusion, interior dry areas, limited wet areas with waterproof membrane (ANSI A118.10).Wood: Over structurally sound wood floors that are subject to residential traffic.Always follow manufacturer’s recommendations when installing product: The handbook further recommends the following installation practices. At a brief glance, these individual substrates and products entail: Minimum cure times are not listed here due to the many combinations of systems in the TCNA Handbook, refer to the TCNA Handbook for specifics. The TCNA Handbook for Ceramic, Glass, and Stone Installations provides recommended minimum cure/dry times for individual substrates and products.
Typically, the maximum heat from a radiant-heating system does not exceed 85☏ (29☌) this level of heat would not affect installation systems and accessories that are designed for tile and stone. These concerns usually are regarding any detrimental effect that the heat from the radiant heating might have on the bond of the tile, approved substrates and when the system can be activated. Questions and concerns are often raised when ceramic tile or stone is to be installed over a radiant-heating system.
