Jotun Paint Consumption Formula:
The Jotun Paint Consumption Calculator estimates the amount of paint required for a specific surface area based on dry film thickness and volume solids percentage. This calculation is essential for accurate project planning and cost estimation in painting projects.
The calculator uses the Jotun paint consumption formula:
Where:
Explanation: The formula calculates the theoretical paint consumption by considering the area to be painted, the desired dry film thickness, and the volume solids content of the paint.
Details: Accurate paint consumption calculation helps in proper budgeting, reduces material waste, ensures adequate coverage, and helps in project scheduling and resource allocation.
Tips: Enter surface area in square metres, dry film thickness in microns, and volume solids percentage. All values must be positive numbers (area > 0, DFT > 0, VS between 0-100%).
Q1: What is volume solids (VS) percentage?
A: Volume solids is the percentage of paint volume that remains as dry film after the solvent evaporates. Higher VS means better coverage and less paint required.
Q2: How do I measure dry film thickness?
A: DFT can be measured using dry film thickness gauges. It represents the actual thickness of the paint film after drying.
Q3: Why divide by 1000 in the formula?
A: The division by 1000 converts the result from cubic millimetres to litres, providing a practical unit for paint measurement.
Q4: Does this account for application losses?
A: This calculation provides theoretical consumption. Actual consumption may be 10-20% higher due to application losses, surface roughness, and other factors.
Q5: How accurate is this calculation?
A: The calculation is theoretically accurate but should be used as a guideline. Always consider adding a safety margin for practical applications.
