1. What is the Sandtex Paint Coverage Calculator?

The Sandtex Masonry Paint Coverage Calculator estimates the amount of paint needed for exterior masonry surfaces based on the area to be painted and the paint's coverage rate.

2. How Does the Calculator Work?

The calculator uses the paint coverage formula:

Where:

• \( Area \) — Surface area to be painted in square meters
• \( 16 \) — Standard coverage rate for Sandtex masonry paint (16 m² per litre)

Explanation: The equation divides the total area by the coverage rate to determine the litres of paint needed.

3. Importance of Accurate Paint Calculation

Details: Accurate paint estimation helps avoid waste, ensures complete coverage, and helps with budget planning for exterior painting projects.

4. Using the Calculator

Tips: Measure the total area to be painted in square meters. The default coverage rate is 16 m²/litre but can be adjusted if using a different product or application method.

5. Frequently Asked Questions (FAQ)

Q1: What affects paint coverage rate?
A: Surface texture, application method, weather conditions, and paint thickness can all affect actual coverage.

Q2: Should I buy extra paint?
A: It's recommended to purchase 10-15% more paint than calculated to account for touch-ups and wastage.

Q3: How do I measure irregular surfaces?
A: Break down irregular surfaces into simple shapes (rectangles, triangles) and calculate each area separately.

Q4: Does this work for interior paint?
A: This calculator is specifically for Sandtex exterior masonry paint. Interior paints may have different coverage rates.

Q5: How many coats should I apply?
A: Typically two coats are recommended for exterior masonry surfaces. Multiply your result by 2 for total paint needed.
