1. Measure all areas that need to be painted. Consider all walls, doors, skirting board and trims and the ceiling.
  2. Enter the measurements of the space that is being painted into the Paint Calculator tool, remembering to include the number of doors and windows, and if the surface is new or a re-paint. This helps to determine the amount of paint required for each surface.
  3. Remember that you may need to do multiple coats - for a premium finish, we recommend 2 coats.

Paint Coverage Tips and tricks

When purchasing paint it’s important to check the spread rate of the product. A lower spread rate means that the coverage of the product won’t be as thick, meaning that more coats will be required.

As a general guide one litre of Dulux Wall, Dulux Trim or Dulux Ceiling paint covers approximately 16m2, while one litre of Dulux Primer will cover approximately 14m2.

The coverage rates will vary depending on surface being coated and the particular product range such as spray paints and the Dulux Design Effects range.
