The symbol of adhesive mixtures must consist of the name of the mixture in accordance with GOST 31189, class designation, values of basic quality indicators (if necessary) and standard designation. Adhesive mixtures are divided into the following classes...
C2 - used for interior and exterior work and meeting increased requirements
C0 – used for laying tiles with normal water absorption (at least 5% by weight) only for interior work
S2− elastic adhesive mixtures
E – mixtures with increased resistance to slipping
C1 – used for interior and exterior work and meeting the minimum regulated requirements
S1 – highly elastic mixtures
F – mixtures with extended open time
T – quick-hardening adhesive mixtures
