Jotun Paint Coverage Formula:
The Jotun Paint Coverage Calculator estimates the amount of paint required to cover a specific area based on the paint's coverage rate and the number of coats needed. This helps in accurate paint purchasing and project planning.
The calculator uses the Jotun paint coverage formula:
Where:
Explanation: The formula calculates the total paint volume needed by dividing the total area by the paint's coverage rate and multiplying by the number of coats.
Details: Accurate paint calculation prevents over-purchasing (saving money) or under-purchasing (preventing project delays). It ensures you have the right amount of paint for consistent color and finish.
Tips: Measure the total area accurately in square metres. Check the paint can for the coverage rate (typically 10-15 m²/L). Consider surface porosity and application method when determining coats needed.
Q1: What is a typical coverage rate for Jotun paints?
A: Coverage rates vary by product type, but typically range from 10-15 square metres per litre for most Jotun interior and exterior paints.
Q2: How do I account for windows and doors?
A: Calculate total wall area first, then subtract approximately 15-20% for standard window and door openings.
Q3: Should I buy extra paint for touch-ups?
A: Yes, it's recommended to purchase 10-15% extra paint for future touch-ups and color matching.
Q4: Does surface texture affect coverage?
A: Yes, rough or porous surfaces may require more paint. Textured surfaces can reduce coverage by 10-20%.
Q5: How accurate is this calculator?
A: The calculator provides a good estimate, but actual usage may vary based on application technique, surface condition, and environmental factors.
