Hydroxypropyl Methylcellulose Powder Used for Skim Coat

Hydroxypropyl Methylcellulose (HPMC) powder is indeed used for skim coat. It is a versatile additive that offers several benefits to this type of application.

Here’s how HPMC powder benefits skim coat:

  • Improved workability: HPMC acts as a thickener, making the skim coat smoother and easier to apply. This translates to a more even and consistent finish on the wall surface.
  • Enhanced water retention: HPMC helps the skim coat retain moisture, preventing it from drying out too quickly. This is crucial for proper curing and minimizes the risk of cracking.
  • Increased adhesion: HPMC promotes better bonding between the skim coat and the underlying surface, leading to a stronger and more durable finish.
  • Reduced sagging and dripping: The thickening properties of HPMC help the skim coat stay in place, minimizing the chances of sagging or dripping during application.
