Cellulose for Skim Coat/Wall Putty

Application of HPMC in wall putty

Application of HPMC in wall putty
HPMC (Hydroxypropyl Methyl Cellulose) is a widely used cellulose ether in the construction industry. It is commonly used as a thickening agent, water retention agent, and binder in many applications, including wall putty.

In wall putty, HPMC is added to improve the workability, adhesion, and durability of the mixture. The addition of HPMC helps in creating a smooth, even surface on walls and prevents cracking and peeling of the putty layer.

Some of the benefits of using HPMC in wall putty include:

  1. Improved workability: HPMC acts as a rheology modifier, which helps to improve the workability and spreadability of the wall putty mixture.
  2. Water retention: HPMC has a high water retention capacity, which helps to keep the wall putty mixture moist for a longer period. This improves the bonding strength of the putty layer and ensures better adhesion to the surface.
  3. Improved durability: HPMC helps to increase the durability of the wall putty layer by reducing shrinkage and cracking.
  4. Better consistency: HPMC helps to create a uniform and consistent texture in the wall putty mixture, which results in a smoother and more even surface on the wall.

Overall, the addition of HPMC in wall putty helps to enhance the performance of the mixture and provides better results in terms of workability, adhesion, and durability.
