Gypsum / POP Plaster Estimation & Application Verification Checklist

Essential Checklist+

Complete these critical checks before approving the work or proceeding to the next construction stage.

✓16 Inspection Points
✓4 Verification Categories
✓Area Measurement & Powder Estimation+
  • Plaster area measured on site — gross area calculated with deductions for openings
  • Plaster thickness confirmed from manufacturer's recommendation — typically 10-15mm walls, 6-10mm ceilings
  • Coverage rate taken from the actual product's technical data sheet, not a generic assumption
  • No cement-plaster dry-volume factor (1.33) applied — gypsum plaster is a single pre-mixed powder
  • Wastage of 5-15% added to powder quantity depending on application method
✓Suitability & Substrate Compatibility+
  • Confirmed the area is NOT a bathroom, kitchen wet zone, external wall, or continuously damp location
  • Substrate confirmed suitable — brick, block (AAC/concrete), or RCC with primer as needed
  • Bonding primer applied and allowed to dry per manufacturer instructions before plastering
  • Substrate surface clean and free of dust, oil, loose material, and standing moisture
  • All electrical conduits and plumbing pipes embedded and chases filled before plastering
✓Mixing, Application & Setting+
  • Mixed quantity matched to the product's working time — not over-mixed in one batch
  • Applied in a single coat to the confirmed thickness — not built up in multiple thin passes unless specified
✓Drying, Protection & Defect Prevention+
  • No water curing applied — gypsum plaster sets by crystallization, not hydraulic cement reaction
  • Freshly plastered surface protected from rain, splashing, and standing moisture until fully dry
  • Completed plaster inspected for cracking, hollowness, and softness before painting
  • Plaster confirmed fully dry before painting

  • No cement-plaster dry-volume factor (1.33) applied — gypsum plaster is a single pre-mixed powder
  • Wastage of 5-15% added to powder quantity depending on application method
  • Ceiling and soffit areas calculated separately from wall areas
  • Final quantity rounded up to whole bags at the actual purchase bag size
✓Suitability & Substrate Compatibility+
  • Confirmed the area is NOT a bathroom, kitchen wet zone, external wall, or continuously damp location
  • Substrate confirmed suitable — brick, block (AAC/concrete), or RCC with primer as needed
  • Bonding primer applied and allowed to dry per manufacturer instructions before plastering
  • Substrate surface clean and free of dust, oil, loose material, and standing moisture
  • All electrical conduits and plumbing pipes embedded and chases filled before plastering
✓Mixing, Application & Setting+
  • Mixed quantity matched to the product's working time — not over-mixed in one batch
  • Applied in a single coat to the confirmed thickness — not built up in multiple thin passes unless specified
  • Surface checked for flatness and plumb with a straightedge while still workable
  • Internal and external corners formed neatly during application
  • Surface finished with the appropriate tool for the specified paint-ready or skim finish
✓Drying, Protection & Defect Prevention+
  • No water curing applied — gypsum plaster sets by crystallization, not hydraulic cement reaction
  • Freshly plastered surface protected from rain, splashing, and standing moisture until fully dry
  • No plastering when ambient temperature is below manufacturer's minimum application temperature
  • Completed plaster inspected for cracking, hollowness, and softness before painting
  • Plaster confirmed fully dry before painting
