1. What is the Exterior Paint Calculator?

The Exterior Paint Calculator India helps homeowners and contractors accurately estimate the amount of paint required for exterior surfaces in Indian conditions. It considers surface area, paint coverage rate, and number of coats needed.

2. How Does the Calculator Work?

The calculator uses the paint calculation formula:

\[ \text{Paint (litres)} = \frac{\text{Surface Area}}{\text{Coverage Rate}} \times \text{Number of Coats} \]

Where:

Surface Area (A) — Total area to be painted in square metres
Coverage Rate (C) — Paint coverage capacity in square metres per litre
Number of Coats (N) — How many layers of paint needed

Explanation: The formula calculates the total paint volume required by dividing the surface area by the paint's coverage rate and multiplying by the number of coats needed for proper coverage.

3. Importance of Accurate Paint Calculation

Details: Accurate paint estimation prevents wastage, saves money, ensures consistent color across the project, and helps in proper budget planning for exterior painting projects in Indian climate conditions.

4. Using the Calculator

Tips: Measure the total surface area accurately, check the paint manufacturer's coverage rate (typically 10-12 sqm/litre for exterior paints in India), and consider 2-3 coats for optimal results. Account for windows, doors, and surface texture.

5. Frequently Asked Questions (FAQ)

Q1: What is the typical coverage rate for exterior paints in India?
A: Most exterior paints in India cover 10-12 square metres per litre for smooth surfaces, but rough surfaces may require more paint.

Q2: How many coats are usually needed for exterior walls?
A: Typically 2 coats are sufficient, but 3 coats may be needed for color changes or better durability in Indian weather conditions.

Q3: Should I add extra paint for wastage?
A: Yes, add 10-15% extra to account for wastage, spillage, and touch-ups, especially for textured surfaces.

Q4: Does surface texture affect paint consumption?
A: Yes, rough or textured surfaces can consume 20-30% more paint than smooth surfaces.

Q5: How do I calculate area for irregular surfaces?
A: Break irregular surfaces into regular shapes (rectangles, triangles), calculate each area separately, then sum them up.
