How to calculate paint for your project.
Having an idea on how to calculate paint is a key factor to save you money time and trips to the store specially when time is limited. It’s difficult to calculate the exact amount of paint due to a few factors such us:
-new vs old
-rolling vs spraying
When calculating paint is always a good practice to add extra square footsie or extra coating to your calculations, Having an extra paint left over will always take you a long way when it comes dow to do final touch ups in your project.
Here is a mathematic equation for ceilings and walls.
-Wall. Room perimeter ft X room high ft = sq ft
-Ceiling. Ceiling width X Ceiling length = sq ft
Keep in mind that windows & doors (typically doors are 20 sq ft and windows 15 sq ft) would have to subtracted:
Window or Door sq ft - Room wall sq ft = wall free of window or door sq ft
Knowing how much sq-ft a gallon coverage (Typically a gallon covers 250 to 400 sq ft.) would simplified your calculation to determent the amount of gallons you’d need for your project so here is my gallon rule, base on a typical house rooms
