A cost-effective method of making your old home look like new is to give it a coat of paint. However, it’s rather difficult to determine the exact quantity of paint you’ll need to buy. This is where a Painting calculator can help.

The paint calculator helps determine the smallest quantity of paint you will need for the entire project. The tool assumes a certain fixed coverage for one litre of paint. 

In order to get an estimate of the amount of paint required, you need to furnish-

  • The length and height of the walls
  • The total area of doors, windows, skirting in square meters (essentially those areas that don’t need paint)
  • Coverage area- what area can be covered by a litre of paint
  • Number of coats that you would probably require (optimal coverage demands a minimum of two coatings)
  • Don’t forget to include the ceiling also if it needs to be painted

The paint calculator will furnish the amount of paint that is required for a single coat and also the total amount needed in litres. Buying the estimated amount should do the job pretty well. However, you need to factor in aspects like condition of the surface, the texture of walls and colour of paints to be used to get a more accurate estimate.
