Abstract:

This specification covers prefaced concrete and calcium silicate masonry units with the exposed-to-view-in-place surfaces are coated with resin, resin and inert filler, or cement and inert filler during manufacture. The coatings are intended to produce smooth resinous tile facing. Facings should be tested according to the prescribed procedures and should meet the requirements for resistance to crazing, cracking, or spalling, resistance to chemicals, adhesion, abrasion, surface-burning characteristics, color, tint, texture, and soiling and cleansability.

Scope:

1.1 This specification covers prefaced concrete and calcium silicate masonry units with the exposed-to-view-in-place surfaces covered at the point of manufacture with resin, resin and inert filler, or cement and inert filler to produce a smooth resinous tile facing. This specification does not address, and therefore is not applicable to, ground-face concrete masonry units that are manufactured by grinding a thin layer off the surface of a concrete masonry unit to expose aggregates within and polishing to produce a smooth, architectural finish.

1.2 The text of this specification references notes and footnotes which provide explanatory material. These notes and footnotes (excluding those in tables and figures) shall not be considered as requirements of the standard.

1.3 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.
