Pool Plaster Crazing

Pool plaster crazing refers to fine cracks that appear on plaster pool finishes due to curing or chemical imbalance.

Causes of Crazing

  • Rapid drying during installation.
  • Unbalanced water chemistry, particularly pH fluctuations.
  • Extended exposure to direct sunlight before water filling.

Preventing and Treating Crazing

  • Maintain balanced water chemistry to prevent surface stress.
  • Use a proper curing process when installing new plaster.
  • Apply pool surface sealants to extend the plaster’s lifespan.
