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…

Cellulose Ether HPMC/MHPC offers the following advantages to Cement Render&Plaster:
● Improve adhesion: Cellulose Ether HPMC/MHPC has good water retention, and helps the cement have full hydration.
● Good workability: Cellulose Ether HPMC/MHPC has excellent thickening and water retention. It can not only extend the open time, but also makes the materials smooth and easy to apply.
● Improve pumpability: Cellulose Ether HPMC/MHPC good thickening and water retention, help the material flow well in the pipe. It reduces blocks during machine spraying.
