HPMC For Cement-based render

Cement-based render is a building material made by mixing cement and sand in a particular proportion. It has been extensively used on internal and external walls to perform the functions of waterproofing, improving fire rating, and aestheticizing the surface through the use of coloured or textured renders. According to its functions, cement-based renders can be categorized into several types: base coat renders, one coat renders, decorative renders, skim coat, self-leveling compounds, waterproofing mortars, etc. Compared with other mortars, it has better fluidity, durability, and workability.

Beskrivelse:

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.

Improved adhesion to various substrates

Increased water repellency and hydrophobicity

Improved water retention, consistency and stability
