Jotun Paint Formula:
The Jotun Paint Calculator helps determine the exact amount of Jotun paint required for your painting project based on the surface area, paint coverage rate, and number of coats needed.
The calculator uses the paint calculation formula:
Where:
Explanation: The formula calculates the total paint volume needed by dividing the area by the coverage rate and multiplying by the number of coats.
Details: Accurate paint calculation ensures you purchase the right amount of paint, avoiding waste from overbuying or project delays from underbuying. It also helps with budget planning and material procurement.
Tips: Measure the total surface area accurately in square metres. Check the paint can for the specific coverage rate (usually 10-15 m²/L for most Jotun paints). Consider adding 10% extra for wastage and touch-ups.
Q1: How do I measure surface area accurately?
A: Measure length and height of each surface, calculate area for each, and sum them up. Don't forget to subtract areas for windows and doors.
Q2: What is a typical coverage rate for Jotun paints?
A: Coverage rates vary by product type: Primer (8-12 m²/L), Topcoat (10-14 m²/L), Specialty coatings (6-10 m²/L). Always check the product datasheet.
Q3: How many coats are usually needed?
A: Most projects require 2 coats for optimal coverage and durability. Dark colors over light may need 3 coats, while primers usually require 1 coat.
Q4: Should I include wastage in the calculation?
A: Yes, it's recommended to add 10-15% extra paint to account for application wastage, brush/roller absorption, and future touch-ups.
Q5: Does surface texture affect paint consumption?
A: Yes, rough or porous surfaces can consume 20-30% more paint than smooth surfaces due to increased absorption.
