This paper will focus on how to paint a room with two coats of paint. The room taken into consideration is an average-sized room with a square cross-section area and equal heights. Ignoring the floor and the ceiling face which tend not to be painted, we are left with four equal faces. The average square room has a length of 10 feet by 10 feet. The height from the floor to the ceiling is averagely 8 feet.
The necessary measurements needed are:
The length
The width
The height
These measurements are basically straight line points that can easily be measured using a tape measure. Placing a tape measure along the lengths, width, and heights of the ceiling will help to read these measurements easily. The tape measure usually has meters and feet metrics. One should accurately use the feet metrics to avoid confusion. However, if one can only measure the distances of the room in meters, then a conversion can be made to feet. A single meter is equivalent to 3.28 feet (Sobecki, 2019) .
Delegate your assignment to our experts and they will do the rest.
These measurements are necessary to calculate the area of the room and hence determine the amount of paint needed to cover up the room. There are four faces that need to be painted. All of the four faces measure 10 by 8 feet. The total area of the four surfaces can be calculated as:
One gallon of paint is enough to paint 400 sq. feet of surface with a single coat coverage. For 360 sq. feet, we will need 0.9 gallons to paint the walls with a single coat coverage. For double coat coverage, we need twice the amount of paint which translates to 1.8 gallon cans of paint.
