How Much Paint For A House

Estimating paint... how much paint do I need?

From the Resene paint and decorating problems solver

To determine how much paint yous need for your project you will need the following data:

Surface surface area of the surface(due south) to be painted (excluding areas where there are windows, doors etc).
Spreading rate of the paint being used.
The number of coats needed.

For example:

To paint the living room walls excluding the ceiling. The walls are 3 metres high, each wall is approx four metres in width, and windows and doors brand up approx 0.v of a metre of each wall leaving a paintable surface of 3.v metres per wall. The surface expanse to pigment is therefore fourteen metres (4 walls x iii.5 metres each) x three metres loftier = 42 square metres.
The walls are currently painted and are in good condition. Resene SpaceCote Depression Sheen is the selected paint arrangement. The production label and data canvass tells us that it has a theoretical spreading rate of 11 foursquare metres per litre. (Yous can view product data sheets and labels here to get the spreading rate info for the product you lot plan to employ.)
As the walls are previously painted and in proficient condition, but two coats of Resene SpaceCote Low Sheen are required.

The amount of paint required is therefore:

Area: 42 foursquare metres

Divided by
Spreading rate: eleven square metres per litre

Multiplied by
Number of coats: ii coats

Equals
42/11 x 2 = vii.6 litres

This tells united states of america that 7.6 litres of pigment is required to paint two coats onto the living room walls. The best idea would then exist to purchase 8 litres giving enough paint to complete the job and sufficient to become back if touch up is required later.

To work out how much paint is needed for your interior or exterior project use our paint calculator:

If you know the 'Expanse' enter it in the 'Area' box beneath, then 'Spreading rate' and 'Number of coats', and so click the 'Calculate' push button.
To summate the surface surface area enter 'Height/length' and 'Width' of surface area to be painted, click 'Calculate Expanse' and enter spreading rate and number of coats, click 'Calculate'.

(Area / Spreading rate) x Number of coats = the litres of paint required

NB: Porous surfaces and shapes (ie corrugated iron) will require more paint.

Roof painting tip

A good dominion-of-thumb for calculating the quantity of roof paint required is: your project's footprint surface area plus about twoscore% (allows for roof pitch, corrugations, soffit overhang, etc). Trough section roofing can crave significantly more than. Typically a complete roof paint system requires surface training using Resene Roof and Metal Wash, i glaze of primer and two coats of topcoat at the recommended coverage rate on the cans.

To estimate paint litres from house plans

To get a rough idea of how much paint you will approximately need when you only have business firm plans to work from, use the following calculations…

Await for the statement of area on the business firm plans – eastward.thousand. 186m²

Divide this by

10 = litres of sealer for ceilings
5 = litres of 2 coats for ceilings
4 = litres of sealer for walls
2 = litres of 2 coats for walls
25 = litres of primer for trim/doors/frames
15 = litres of 2 coats for trim/doors/frames

Enter the foursquare expanse (m²) of house plan below and press "Summate"
