Cement based render(plaster/mortar) is the mixture of suitable sand, cement and water which is generally applied to masonry interiors and exterior to smooth wall surface. HPMC plays a key role in cement based render(plaster/mortar) to achieve the excellent performance of water retention, open time, workability, crack resistance, sag resistance, etc.

HPMC for Cement Render&Plaster features:
Hydroxypropyl methyl cellulose(HPMC) is used in cement render and plaster as a thickening and water retention additive.
Hydroxypropyl methyl cellulose(HPMC) enable temperature tolerance, improves fresh mortar density (air entrainment) and workability (rheology)
Hydroxypropyl methyl cellulose(HPMC) promises high performance in stickiness and cement retardation at site
