Which pair correctly matches the cementitious backer unit (CBU) material specification with the interior CBU installation specification?
Which ANSI material specification covers load-bearing, bonded waterproof membranes used under thin-set ceramic tile and dimension stone?
Which ANSI material specification covers crack-isolation membranes for thin-set ceramic tile and dimension stone?
What traditional live-load deflection limit does the TCNA Handbook use for framed floors that will receive ceramic or porcelain tile?
A framed floor will receive 12-by-12-inch marble tile. Which deflection criterion is the stricter industry requirement commonly applied to natural stone?
Why is paper-faced gypsum board the wrong backing for a tiled tub surround or shower wall?
In TCNA unbonded mortar-bed floor method F111, what is the typical minimum thickness of the reinforced mortar bed?
Compared with an unbonded (F111) mortar bed, why can a bonded mortar bed such as TCNA F112 be thinner?
What is the purpose of a cleavage membrane under an unbonded floor mortar bed?
What minimum slope do TCNA wet-area methods and plumbing practice require for a tiled shower floor toward the drain?
A shower floor is 4 feet from the curb to a center drain. At the required 1/4 inch per foot slope, how much lower must the drain be than the high point at the curb?
Under TCNA EJ171, where must movement joints be provided in interior tilework in addition to any field joints?

Question · Hard
How does TCNA EJ171 change interior field-joint spacing when the tile will see moisture or direct sunlight?
What is a common EJ171 minimum width for interior perimeter movement joints at restraining walls?
A concrete slab has a saw-cut control joint in the field of a future tile floor. What is the correct tile-layout response?
A wood-framed floor spans 15 feet between supports. If the ceramic-tile deflection limit is L/360, what is the maximum allowed live-load deflection?
A low spot in a concrete floor is filled with a gypsum-based patch so tile can be set the same afternoon. Why is that preparation rejected?
When a wood-panel substrate is permitted under tile, which panel type is the industry-specified glue grade?
When cementitious backer units are installed over a wood floor as a tile underlayment, which preparation is consistent with ANSI A108.11 practice?
Why do TCNA and most bonded thin-set manufacturers want a new concrete slab to cure on the order of 28 days before tile is installed?
Which ANSI installation standard covers installing load-bearing, bonded waterproof membranes for thin-set ceramic tile and dimension stone?
A specifier asks for "the waterproof membrane" over hairline slab cracks and no other treatment. Why may an A118.10 membrane alone be the wrong product?
A shower bench top is 6 feet from the drain along the sloped path. At 1/4 inch per foot, what total drop is required along that path?
