1. What is the Paint Calculator?

The Paint Calculator estimates the amount of paint needed to cover a given area, accounting for the paint's coverage rate and number of coats required. It helps prevent over- or under-purchasing paint for your project.

2. How Does the Calculator Work?

The calculator uses the paint calculation formula:

Where:

• \( area\_m2 \) — Total area to be painted in square meters
• \( coverage\_m2\_per\_liter \) — Paint coverage rate (m² per liter)
• \( coats \) — Number of coats needed

Explanation: The formula calculates the base amount needed for one coat, then multiplies by the number of coats required for complete coverage.

3. Importance of Accurate Paint Calculation

Details: Proper paint estimation saves money by preventing over-purchasing, ensures color consistency by buying all paint at once, and helps plan project timelines more accurately.

4. Using the Calculator

Tips: Measure your walls accurately, check the paint can for coverage rates (typically 8-12 m² per liter), and consider adding 10% extra for wastage. Always round up to whole cans when purchasing.

5. Frequently Asked Questions (FAQ)

Q1: What's a typical coverage rate for paint?
A: Most paints cover 8-12 m² per liter, but this varies by paint type and surface texture. Always check the manufacturer's specifications.

Q2: How many coats are usually needed?
A: Most projects require 2 coats - one base coat and one finish coat. Dark colors or dramatic changes may need 3 coats.

Q3: Should I account for doors and windows?
A: Yes, subtract approximately 10% for standard windows and doors, or measure their exact area if precision is important.

Q4: Does surface texture affect coverage?
A: Yes, rough textures like stucco can reduce coverage by up to 20% compared to smooth surfaces.

Q5: How should I adjust for primer?
A: Calculate primer separately using the same formula but with primer-specific coverage rates (typically higher than paint).
