Where:
Explanation: The formula calculates material cost by dividing total area by coverage to get gallons needed, then adds labor cost based on area.
Details: Accurate cost estimation prevents budget overruns, helps compare contractor quotes, and ensures proper material purchasing for painting projects.
Tips: Measure wall area accurately, check paint can for coverage specifications, get current paint prices, and research local labor rates for best results.
Q1: How do I calculate wall area?
A: Measure height and width of each wall, multiply, and sum all areas. Subtract windows and doors for net paintable area.
Q2: What is typical paint coverage?
A: Most paints cover 250-400 sq ft per gallon. Check manufacturer specifications as coverage varies by paint type and surface.
Q3: Should I include primer cost?
A: Yes, if priming is needed. Calculate primer separately using the same formula with primer coverage and price.
Q4: How many coats should I calculate for?
A: Typically 2 coats for good coverage. Multiply paint quantity by 2, but labor may not double as second coat is faster.
Q5: What affects labor costs?
A: Surface preparation, wall condition, ceiling height, trim work, and local market rates all influence labor pricing.
