FIELD: chemistry.
SUBSTANCE: invention relates to a ready for application composition for joint sealing. A system of the composition for joint sealing includes the inhibited for hardening, preliminarily wetted, hardening, and ready for application composition for joint sealing and an initiator of hardening. The inhibited for hardening, preliminarily wetted, hardening composition for joint sealing includes a base of the ready for application, hardening composition for joint sealing with a calcium-free phosphate hardening-preventing agent, which prevents chemical hydration of a gypsum component of the hardening composition for joint sealing. The base of the composition for joint sealing does not contain calcium carbonate. The initiator of hardening includes alum for re-initiation of chemical reactions of hydration.
EFFECT: technical result consists in reduction of the time for hardening of joint-sealing compositions.
