# Metallic Coating And Patina FinishQuantity And Cost Calculator

This calculator requires the use of Javascript enabled and capable browsers. Though it does intensive math calculations, it is a close estimator and enables the user to approximate the amount of coating or finish and primer required for a given surface, based on parameters entered. THIS IS A COMPLEX CALCULATOR! Pay close attention to the instructions and options. It calculates the square footage of surfaces requiring finish, less any deducted area. It assumes no deductions; it also assumes that surfaces are generally flat. For surface deductions, you may use fractions such as 1.5 or .8 in the deductions field. The entry of 1 is 4 square feet of deduction from the square footage. It assumes that application metallic coating goes on at about 100 square feet per gallon and 250 square feet for base primer; you may change either or both if you wish, you WILL have to insert 250 square feet for Patina finishes. It also assumes surfaces are smooth but allows for both roughness and dryness of the surface. It takes into consideration spraying, which takes slightly more finish coating or finish or primer than the alternatives, brushing or rolling, either of which requires roughly the same quantity of finish but less than spraying. It considers one or two application coating or finish coats and assumes no base primer coat. The algorithm for the base coat is slightly different and based (no pun intended) on the different composition of base coat primer; it also allows for a different price. NOTE: The square footage of the surface is based on the entered actual or estimated measurements. All other square footage reporting is CALCULATED based on the entered surface size and the perceived rate of finish coverage determined by coverage options selected. If you have a surface that is difficult to measure, you may "guesstimate it" by entering a value the is 1 in the width field and 5 in the length field for 5 square feet or 6 in the length for 6 square feet, and so on.

It also considers surface texture; standard texture is that of a similar appearance to a generally smooth and dry surface. Uncheck the default if the surface is very smooth and not dry. Rough and dry surfaces take up to 65% more finish for the same square footage as generally smooth surfaces. Because of the varied conditions of such surfaces, we consider it as more square footage since in reality, it is just that. If you wish to finish the surface and it is NOT smooth and is dry, check one box or the other; you may also check both boxes if you feel the surface is very porous or extremely rough. Checking both will calculate a much higher square footage than actual but calculates very closely to the required quantity of finish. If you wish to use a primer base coat, check the base coat box. Enter the cost of the coating or finish per gallon for the application and for the base primer coat, if used; the total prices of the finishes required are calculated. You may also enter labor cost per hour and the estimated number of hours; or your may enter 1 hour and the prices estimate for the labor for the entire job. To do another, click the Clear Values button and then enter a new set of values. You may also wish to just change certain fields and recalculate; however, remember that you MUST click Calculate after each modification or group of modifications prior to seeing the corrected final values. Calculated accuracy of current Javascript enabled browsers is generally 16 places. Be aware that the surface square footage assumes square corners; you may have to extrapolate in such cases. The finish square footage of the surface less deductions, and has the selected options of coats and other increases or decreases in finish quantity for it. It is actually the amount of calculated square feet for all of the conditions and determines the amount of gallons required.
