Measuring the area
In measuring the area, square footage is the typical unit used. A surface area is wall height multiplied by width, in square foot. Get the surface area of each wall, then add the numbers to get the total square footage. Measuring trim casings is usually measured in Linear feet
Estimating paint quantity
Typically, you can anticipate one paint gallon to cover 400 square feet of smooth surface. If the surface is finished, one gallon will cover more like 300 square feet. Finished walls will, in general, absorb a lot more paint. Do the computations, as clarified above, to decide the number of gallons you should purchase. Make sure to double your numbers if it appears likely that the walls will profit by a double coat. Note: any time one changes the color or sheen when painting will need 2-coat application. Using pastel colors will require 3-coats
Specifying the labor cost
It’s crucial to know how long painters should take to finish a task and precisely calculate labor costs. Ensure that you include the wall prep & protection prep of covering non painted areas such as floors, furniture & window treatments. If you have at any point painted yourself, you know how long it requires the painting preparation process in the correct way. Caulking, wall repairs and sanding are pretty daunting tasks. However, all are fundamental for a quality result you will be satisfied with.
As in house painting, interior painting for commercial spaces is typical $1 – $3 per foot. Rates include 1$ per square foot for walls only, 2$ per square foot for walls and ceiling. Trim is priced .70 per Linear Foot. While Interior Doors are priced @ $25. Per side. Excellent quality paint, for the most part, costs between $40-$55 per gallon. For Exterior Projects generally speaking, paints cost higher to protect surfaces from the elements.
