Ceiling Paint Formula:
The Ceiling Paint Calculator helps determine the exact amount of Dulux paint needed to paint a ceiling based on room dimensions, paint coverage rate, and number of coats required. This ensures you purchase the right amount of paint without waste.
The calculator uses the paint calculation formula:
Where:
Explanation: The formula calculates the total area to be painted and divides by the paint's coverage rate, then multiplies by the number of coats needed for complete coverage.
Details: Accurate paint calculation prevents over-purchasing (saving money) and under-purchasing (avoiding color mismatch from different batches). It ensures efficient project planning and reduces waste.
Tips: Measure room dimensions accurately. Check the paint can for coverage specifications (typically 10-16 m²/litre for ceiling paints). Consider an extra 10% for wastage on textured surfaces.
Q1: What is typical coverage for Dulux ceiling paint?
A: Most Dulux ceiling paints cover 12-14 m² per litre, but always check the specific product specifications.
Q2: How many coats are usually needed for ceilings?
A: Most ceilings require 2 coats for even coverage and color consistency, especially when painting over darker colors.
Q3: Should I include windows and doors in my calculation?
A: For ceiling calculations, you typically don't subtract openings since ceilings are continuous surfaces.
Q4: How much extra paint should I buy for wastage?
A: Add 10-15% extra for textured surfaces, cutting in, and brush/roller absorption.
Q5: Does this calculator work for walls as well?
A: The same formula applies to walls, but you need to subtract window and door areas from the total wall area.
