The range is very easy to calculate because it is simply the difference between the largest and the smallest observed values in a data set. Thus, range, including any outliers, is the actual spread of data.
Re: Elastomeric Cool Roofing Systems Cost Per Sq? How Much You Guys Charging. Matrial and labor I can do them for $125 per sq depending on the project I can usually add between $75 up to $100 profit per sq and still stay competive with the competition.
In the example shown, the cost of a 2.5-mil thick coating using a powder costing $2.50 per pound and having specific gravity of 1.4 is 4.6 cents per square foot. This assumes 100 percent efficiency.If overspray recovery is 98 percent, the cost would be about 4.69 cents per square foot.eferring to the table, actual coverage of the powder is 128.8 square feet per pound and the cost per square foot of a 1-mil thick dry film is 2.29 cents. Thus, the actual cost of material for the epoxy powder coating is less than that of the liquid paint coating by 1.23 cents per square foot.
