what we do

Q How do I work out how much paint I'll need for my project? It seems that every time I paint, I either have leftover paint or not quite enough and have to go back to the store for more!

A

Good question. There are lots of factors involved, but for most interior and exterior projects the following will usually give you an accurate estimate of your needs. Simply calculate the square metres of the surfaces to be painted and divide by the number of square metres that the manufacturer indicates can be covered by a Litre of your selected paint.

Wall Estimating Example
For example, if a room is 4 metres by 5 metres with 2.4m ceilings, your square metreage is 43.2m (the circumference (18) times the ceiling height (2.4). If you have a number of windows and doors, subtract the square metres of those openings (standard doors are about 2.1 sq/m, standard windows about 1.5 sq/m). For many paints, including primers and stains, a litre will cover about 14 square metres (the product label will show the coverage). Since two coats are normally recommended for most projects, don’t forget to double your quantity when purchasing. Remember, it's always a good idea to have a little leftover paint for future touchups.


As mentioned earlier, there are a number of factors that affect how much paint you'll need. These include the type of surface being covered and the color currently on the surface as well as the one being applied. The best way to ensure that you have the proper amount of paint for your project is to take your measurements and other information (surface being covered, its condition and color) to your local independent paint retailer. And remember, if it all seems too much, just call Prestige Painting Group, and we will be more than happy to help.
