Frequently Asked Questions
What is the scope of the Arizona ROC CR-48 license?
The CR-48 license authorizes contractors to install ceramic, glass, plastic, and metal tile, mosaic tile, marble, slate, quarry tile, terrazzo, and structural substrate preparation including cementitious backer units, waterproof membranes, mortar beds, and movement joint systems on both commercial and residential projects.
What is the minimum deflection requirement for ceramic tile versus natural stone?
According to TCNA and ANSI A108 standards, floor framing supporting ceramic and porcelain tile must not exceed a maximum deflection of L/360 under total design load. For natural stone tile installations (such as marble, granite, or slate), maximum allowable floor deflection is L/720 due to stone's lower flexural strength and higher brittleness.
What are the TCNA EJ171 movement joint spacing rules?
Under TCNA Method EJ171, interior tile installations exposed to normal conditions require movement joints every 20 to 25 feet in each direction. For exterior installations or interior tile exposed to direct sunlight or moisture (such as glass enclosed atriums), movement joints must be spaced every 8 to 12 feet in each direction, with a minimum 1/4-inch joint width.
How must respirable crystalline silica be controlled when cutting tile on jobsites?
Per OSHA 29 CFR 1926.1153 Table 1, tile setters operating stationary or handheld masonry saws must use a continuous water delivery system that feeds water to the blade during cutting, or employ an integrated shroud and dust collection system with a HEPA vacuum efficiency of 99.97%. Continuous wet cutting eliminates the need for respirators under Table 1 for shifts up to 4 hours.
