Masonry mortar is used for masonry and component installation of bricks, stones, blocks, etc.; plastering mortar is used for walls, Plastering on the surface of the ground, roof and beam-column structure to meet protection and decoration requirements.

Properties of hydroxypropyl methylcellulose (HPMC) in masonry/rendering mortar:
• The water retention performance of hydroxypropyl methylcellulose can reduce the water absorbed by the porous substrate and promote better hydration of the cementitious material. In large-area construction, it can greatly reduce the probability of early mortar drying and cracking and improve the bond strength. ;

• The thickening ability of hydroxypropyl methylcellulose can improve the wetting ability of wet mortar to the base surface;

HPMC can improve the stability of wet mortar, and can reduce or avoid delamination and bleeding;

• HPMC can improve the lubricity and rheology of mortar, reduce resistance, thereby increasing pumpability and reducing labor intensity;

Hydroxypropyl methylcellulose can improve the sag resistance of mortar, and when applying thick mortar, it can reduce construction time and reduce waste.
