Environmental Cement Based Covering Mortar For Insulation System
YUNYAN anti-crack mortar forms a highly tough layer, reduces crack
transmission in ceramic tile, thin brick, marble and stone
installed using thin-set method.
■It has great cohesive force.
■It is non-toxic, harmless, and no radiation.
■It has good workability and anti-sag resistance.
■It is fast cure. Dries in a few hours to receive finished surface.
■It has good water retention. It is not easy to create cracks after
■It has good cracking resistance and seepage-proofing, which will
support better protection for the wall.
Scope of application
■Applied to the external walls and internal walls self-leveling of
■Applied to self-leveling of building thermal insulation system.
Treatment of base plane
■Base plane should be no grease, release agents, rusty metal,
wooden meal, paint, plastic, dust and other any pollutants which
can affect the cohesive strength of mortar.
■The base materials should be pre-wet by water before construction.
■Treat the base plane by interface treatment agent to improve the
cohesive strength when repair the concrete.
■Pour one pack (50kg) of anti-cracking plaster mortar into a
container with 10-10.25L water, stir completely with electric
stirrer for 3-5 minutes. Then scrape the paste until getting
■Product could harden under normal temperature conditions. The
construction no need water maintenance, but need water maintenance
in high temperature and dry weather to ensure the strength
