Girly DIY question.?
Question:I hope the answer to this is not too simple but.
How do you work out how many tins of paint you will need to paint a certain sized room?!
Answers:
Length x width (in metres) gives you the surface area in square metres. Look on the paint tin for how many square metres it covers (it usually covers less than it says though). Compare the two!
Hello.. painting!? I love painting!!
Well if you go the behr.com website they have a calculation of there. It will ask like square footage and wall size.Hope this helps
work out the height of the room and lengh, then work out the square metre's needed. Look on the back of the paint tin and it will give an area it covers. Buy an extra tin just incase and if you don't use it, take it back for a refund.
Happy painting.
Aha! The tin of paint will tell you what 'area it will cover next to the measurement of paint contained e.g 1L 15 sq M (just an example)
You work out the area measurement of a wall by multiplying the height by the width of the area to be painted. Do this on all the walls and then add the figures together. Then you can see how many pots you'll need of whichever paint you want to use.
Don't forget, if you're painted over a dark coloured surface you will need more layers of paint.
need to look at the room ... , but a 3x4 mtr room 2x.so 10ltres.includes making good , base coat etc
Roughly measure the are to be painted (I am assuming walls and or ceiling) The square metre figure is shown on most tins - so if a tin says it will cover say, 5 sq mtrs then you do your calculation based on that.
Get the size of the room, length x width of each wall in meters gives you the m2. On the back of the paint tin it will tell you how many m2 the tin of paint will cover. I would get a couple of extra tins though to be safe.
Happy painting
Take the lenght of each wall and the height of each wall and times it. So if you had a room that was 10' x 12' and the walls are eight feet tall, do the following math. 10' x 8' = 80 square feet, and you have two of these walls so you x 80sqft x 2=160 sqft. Now you times the other wall 12'x8'=96sqft x 2 = 192 sqft. Now add those two totals together and you get 352 sqft. Most gallons of paint cover 400 sqft, you would need 1 gal per coat and with two coats you would need two gals. for the walls. To get ciling X the lenght and width so 10' x 12' = 120 sqft. You need 1 gal foer your ceiling
Most tins will tell you coverage details etc, all you have to do is work out the size of the room. Don't forget to make sure to save your expensive paint and make it go further by putting a cheap coat of white or magnolia over a dark colour first and then fill any imperfections. It's a lot easier that way. Good luck pet.
look at a wall that you plan to pain, measure its length and width.
then :
area1 = (Length)(Width)
you now have the area, look on the paint can it will tell you how much area it will cover. If you have more than one wall you "add the area" of all walls together.
Remember the first coat will take the most, if you want more coats I would figure about half of the first coat, you may want to figure a higher value though.
To figure 3/4 rather than 1/2 you will:
(Total area)(3/4)=Second coat.
------------------------------...
Area1 +Area2+Area3 = total area
total area / 2 = secondcoat . .//see above
total area + secondcoat = paint needed
------------------------------...
Let's see, if my wall is Length = 10ft and width 10ft. my area is 100ft
If I have two walls like this
100 + 100 = 200 feet
==============================...
second coat = (200/2) = 100 feet
or maybe:
second coat = (200)(3/4) = 600/4 = 150
==============================...
300 feet total
If one can covers 25 feet then to put two coats on this I will require (300 / 25) = 12 cans of paint.
Roughly calculate the square footage that you want to paint. Next when you go to buy paint ask the sales person how much paint you need.
Be careful on this one. I asked my neighbour who has an identical house how much paint he bought and he told me four tins. After the job was done I had two tins left and told him so. "Strange he said, I had two left over as well !"
The label on the paint tin will give you the coverage. Take into consideration the current wall and paint condition though. I've found that brand new drywall or walls that have not been painted in a long time can soak up a lot of paint.
Also, if you are applying two coats of paint (gives a nicer finish I think), the second coat will only require about 1/2 as much as the first.
Measure your room and ask the person at the paint counter - they should be able to give you advice. Better to buy a little less than too much. You can't return paint that has a custom color, but you can always go back and get a bit more
Just buy 5 litres if you need more get some. You should eventually be able to guess.
All these system to work it out are rubbish because it depends on so many factors IE thickness of paint and the substrate
measure room get square feet total on the back of the can of paint it will tell you the square feet of coverage
measure room
work out area
look on tin to find out coverage
