Calculating the amount of paint needed depends largely on the surface area
of the wall in the room.
Measure out the perimeter of the room i.e the entire length of the
four sides of the room or as the case may be.
Then measure out the height of the room, the length from floor to the
ceilling. These could be in meters or in feet depends on what you are used
to.
Now calculate the surface area of the room which is simply by multiplying
the total length of the room by the ceilling heigth.
For a standard Nigerian room, it is usually 3.6m x3.6m or 12ft x12ft
others can also make theirs 3.6m x3.0m or 12ft x 10ft depends on the plan
of the house.
After this measure out the openings in the room, most often the windows
and doors.
For windows it may be 1.2m x 1.2m i.e 4ft x 4ft or 1.8m x 1.2m i.e 6ft x
4ft, the height of windows are mostly 1.2m or 4ft while the length is what
usually varies. Multiply the height by the length of all the windows and
then do same for doors.
For doors the height is usually 2.1m or 7ft and the length is 0.9m or
900mm or 3ft do multiply the height by the length and sum the total areas
of openings in the room then subtact from the total surface area of the
room.
After determining your area (square feet or m2) then choose your paint
check the label of the paint bucket for the spread rate for the
paint.Spread rate is just the number of square feet (m2)of surface each
coat of paint will cover .After finding out, divide the total surface area
you measured earlier by this number to determine the number of paint
bucket/liter you will need for each coat.
The number of coats you should apply depends on the type of paint, the
colour,the nature of the colour you are applying, method of application
and the nature of the surface.
For example, you will likely need a second coat of paint when covering a
dark color with a lighter one. Also, certain surfaces, like exterior
masonry, are very porous and absorb a great deal of paint. In such cases,
a second coat is often needed to give the paint a uniform appearance.
Using a brush will put on a heavier, better-hiding coat than roller
application.

how do you calculate the perimeter for external walls of 18,500mm by 16,300mm and 14,900mm by 19,700mm at all four corners of the bungalow “building” and the height of the building to ceiling level is 3015mm, please help me how do i calculate the perimeter of bungalow.
Thanks for your assistance and consideration.

PLS i cant find the pread rate from the paint buckect. ihow can i trace to find it.God bless
Guys, u ar soo amazing. Hw i wish i knew dis site long ago. Kudos to u all
