Paint Calculation Formula:
The Jotun Paint Calculator helps determine the exact amount of paint needed for a painting project based on surface area, paint coverage rate, and number of coats required. This ensures you purchase the right quantity of Jotun paint without waste or shortage.
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 prevents over-purchasing (saving money) and under-purchasing (avoiding project delays). It also ensures consistent color and finish across the entire surface.
Tips: Measure the total surface area accurately. Check the coverage rate specified on the Jotun paint can (typically 10-14 m²/L). Consider applying a primer coat for better results on new surfaces.
Q1: How do I measure surface area accurately?
A: Measure length and height of each wall/surface, calculate area (length × height), and sum all areas. Subtract areas of windows and doors.
Q2: What is the typical coverage rate for Jotun paint?
A: Coverage varies by product type but generally ranges from 10-14 m² per litre for most Jotun interior and exterior paints.
Q3: How many coats are usually needed?
A: Most surfaces require 2 coats for optimal coverage and durability. Dark colors or dramatic color changes may require 3 coats.
Q4: Should I include a waste factor?
A: It's recommended to add 10% extra paint to account for spills, brush loading, and touch-ups.
Q5: Does surface texture affect paint consumption?
A: Yes, rough or textured surfaces can require 10-20% more paint than smooth surfaces due to increased surface area.
