Wet-set and cured mortar beds are different ANSI documents
Wet-set mortar and a cured mortar bed are different documents on the Tile Council ANSI status page. A108.1A is installation of ceramic tile in the wet-set method with Portland cement mortar, listed as the 2026 edition and described as current. A108.1B is installation on a cured Portland cement mortar bed with dry-set, modified dry-set, or improved modified dry-set cement mortar, listed as the 2023 edition and also described as current.
Two mortar methods, two numbers
A108.1C is the contractor's option between those two approaches, listed as 2023. The wet-set number and the cured-bed number are not interchangeable. The status page names the method for each. It does not paste the mortar proportions or the trowel sizes.
The text is a purchased publication
The same status page is a list of edition years and whether the publication for sale is current. Open PINS means the association has told ANSI it intends to revise or create a standard. Continuous maintenance means the document stays open for comment. These editions are described as current, and the publications are sold through the Tile Council and ANSI. The page does not paste the standard's requirements.
