Emulsion Paint Coverage Formula:
Emulsion paint coverage calculation helps determine the amount of paint needed to cover a specific area based on the paint's coverage rate and number of coats required. This ensures accurate purchasing and minimizes waste.
The calculator uses the emulsion paint coverage formula:
Where:
Explanation: The formula calculates the total paint volume needed by dividing the area by the coverage rate per litre, then multiplying by the number of coats.
Details: Accurate paint calculation prevents over-purchasing (saving money) and under-purchasing (avoiding color mismatch from different batches). It also helps in project planning and budgeting.
Tips: Measure the total area accurately in square metres. Check the paint can for the specific coverage rate (typically 10-14 m²/litre for emulsion). Consider adding 10% extra for wastage and touch-ups.
Q1: What is a typical coverage rate for emulsion paint?
A: Most emulsion paints cover 10-14 square metres per litre, but this varies by brand, quality, and surface porosity.
Q2: Should I include windows and doors in the area calculation?
A: No, subtract the area of windows and doors from your total wall area for more accurate calculation.
Q3: How many coats are usually needed?
A: Most projects require 2 coats for even coverage and color consistency, but dark colors or porous surfaces may need 3 coats.
Q4: Does surface texture affect coverage?
A: Yes, rough or textured surfaces require more paint than smooth surfaces due to increased surface area.
Q5: Should I buy extra paint for touch-ups?
A: Yes, it's recommended to buy 10-15% extra for touch-ups and future repairs, keeping some for color matching.
