Frequently Asked Questions
How much paint do I need per square foot?
One liter of paint covers approximately 100-120 sq ft with 1 coat. For 2 coats on a 10x12 ft room (approx 400 sq ft wall area): need about 7-8 liters of paint.
How to calculate paint for a room?
Measure each wall (L×H), add together, subtract doors (21 sq ft) and windows (15 sq ft). Multiply by number of coats. Divide by paint coverage per liter.
What is the difference between interior and exterior paint?
Interior paint is formulated for low-UV, washable surfaces with matte/eggshell finishes. Exterior paint is weather-resistant with UV protection and flexible formulations.
