Cement plaster is a mixture of suitable plaster, sand, portland cement, and water, typically applied to masonry interiors and exteriors to achieve a smooth surface, while interior surfaces sometimes get a final layer of gypsum plaster.
Hydroxypropyl methyl cellulose( HPMC) powder are used as thickeners and water retention additives in cement based renders and plasters mortar applications. However, beyond these main functionalities they impact many other performance parameters of cement renders and plasters.
Improvement of workability and crack resistance
• HPMC and MHEC powder enable temperature tolerance, improves fresh mortar density (air entrainment) and workability (rheology)
• HPMC and MHEC powder promises high performance in stickiness and cement retardation at site
