HOW TO USE IT
How to use the Plaster Repair Cost Calculator
- 1
Measure the area: Total the plaster area to repair. Larger areas and higher condition scale the work.
- 2
Apply a condition factor: Minor cracks are the baseline; moderate and major damage multiply the rate because they need more buildup.
- 3
Add prep and coats: Preparation for cleaning, primer and masking is a fixed line, and multiple coats add to the work.
- 4
Total and validate: 200 sq ft at $3.50 over 2 coats at a 1.4 factor is the main cost, plus prep. Use the Plaster Repair Cost Calculator.
