1. What is the Exterior Paint Estimator?

The Exterior Paint Estimator calculates the amount of paint needed to cover an exterior surface based on the total square footage and the paint's coverage rate. It helps homeowners and professionals plan their painting projects more accurately.

2. How Does the Calculator Work?

The calculator uses the paint calculation formula:

Where:

• \( Sq\,Ft \) — Total square footage to be painted
• \( Coverage \) — Paint coverage rate (square feet per gallon)

Explanation: The formula divides the total area by the paint's coverage rate to determine how many gallons are needed.

3. Importance of Accurate Estimation

Details: Accurate paint estimation prevents over-purchasing (saving money) or under-purchasing (preventing project delays). It also helps with budgeting and planning.

4. Using the Calculator

Tips: Measure your exterior surfaces carefully. Check the paint can for the exact coverage rate (typically 250-400 sq ft/gal). Remember to account for multiple coats.

5. Frequently Asked Questions (FAQ)

Q1: How do I measure my exterior square footage?
A: Calculate each wall's area (height × width), add them together, then subtract windows and doors (about 20 sq ft per standard window/door).

Q2: What's a typical coverage rate?
A: Most exterior paints cover 250-400 square feet per gallon. Check your specific paint's label for exact coverage.

Q3: Should I buy extra paint?
A: Yes, purchase 10-20% extra for touch-ups and to account for surface texture and application method variations.

Q4: Does this account for multiple coats?
A: No, multiply your result by the number of coats needed (typically 2 for exterior projects).

Q5: How does surface texture affect coverage?
A: Rough surfaces (like stucco) may require 20-30% more paint than smooth surfaces.
