1. What is the Exterior Paint Calculator?

The Exterior Paint Calculator estimates the amount of paint needed to cover exterior surfaces based on square footage. It uses a standard formula that accounts for typical coverage rates and multiple coats.

2. How Does the Calculator Work?

The calculator uses the paint calculation formula:

Where:

• \( Sqft \) — Total square footage of exterior surfaces
• 350 — Standard coverage of one gallon of paint (square feet)
• 2 — Factor for two coats of paint

Explanation: The formula divides the total area by the coverage rate of one gallon, then multiplies by 2 to account for two coats of paint.

3. Importance of Accurate Paint Calculation

Details: Proper paint estimation helps avoid purchasing too much or too little paint, saves money, and ensures consistent color application across the entire project.

4. Using the Calculator

Tips: Measure the total square footage of all exterior surfaces to be painted. For irregular surfaces, break them down into simple shapes and calculate each area separately before summing them up.

5. Frequently Asked Questions (FAQ)

Q1: Why divide by 350?
A: 350 square feet is the typical coverage of one gallon of exterior paint for a single coat on smooth surfaces.

Q2: Why multiply by 2?
A: Most exterior painting projects require two coats for proper coverage and durability.

Q3: Does this work for all paint types?
A: Coverage may vary slightly by paint quality and surface texture. Check manufacturer specifications for premium paints.

Q4: How should I measure complex exteriors?
A: Break down walls into rectangles (height × width), then subtract areas not being painted (windows, doors).

Q5: Should I buy extra paint?
A: It's recommended to purchase 10-15% more than calculated to account for touch-ups and waste.
