Details: Accurate estimates help in budgeting, comparing contractor quotes, and ensuring you purchase the right amount of materials without overspending or running short.
Tips: Measure the total wall area accurately. Consider that most paints cover 300-400 square feet per gallon. Labor rates vary by region and complexity of the job.
Q1: How do I calculate wall area?
A: Measure length and height of each wall: Area = Length × Height. Subtract areas of windows and doors.
Q2: What is typical paint coverage?
A: Most interior paints cover 300-400 sq ft per gallon. Check the paint can for specific coverage information.
Q3: How much should I budget for labor?
A: Labor costs typically range from $1-3 per square foot, depending on preparation needed and local rates.
Q4: Should I include ceiling painting?
A: Yes, if painting ceilings, calculate ceiling area separately and add to total area. Ceilings may require different paint types.
Q5: How many coats are typically needed?
A: Most jobs require 2 coats for even coverage and durability. Double your paint calculation for 2 coats.
