Question 1

How much paint do I need for a room?

Accepted Answer

Calculate the total wall area (2 × (length + width) × height), then divide by the coverage rate (typically 10 m² per litre). Multiply by the number of coats needed.

Question 2

How many coats of paint do I need?

Accepted Answer

Most walls need 2 coats for even coverage, especially when changing colors significantly. A single coat may suffice for touch-ups or when using the same color.

Question 3

How much area does 1 litre of paint cover?

Accepted Answer

On average, 1 litre of paint covers about 10 m² per coat, though this varies by paint type, surface texture, and application method.

Question 4

Should I subtract windows and doors from paint calculations?

Accepted Answer

For more accurate estimates, subtract the area of large windows and doors. However, many people skip this since it provides a small buffer for touch-ups.
