Mr. Mandu, I decided to start a new discussion, rather than to keep going back and forth on Mr. Thomas' page. Originally, I asked why would you want to apply a "cheap stain" to your home that you just paid $XXX,XXX for. It's not like comparing your BMW and your wax job, it's like comparing your BMW to your paint job. Telling the dealer to just leave off the paint and going to your local hardware store and buying generic paint for your vehicle.
This could be anyone's stain. Just use the same formula for the stains you are comparing.
Stain A (2 coats)
Price: $278.00 per pail ÷ 5 = $55.60 per gallon.
1st coat coverage - 250 sq. ft. per gallon on smooth wood.
2nd coat coverage – 350 sq. ft. per gallon on smooth wood.
1st coat - $55.60 ÷ 250 = $0.2224 X 100 = $22.24
2nd coat - $55.60 ÷ 350 = $0.1589 X 100 = $15.89
Total cost per 100 sq. ft. = $38.13
Stain B ( 2 Coats of Stain plus 1 Coat of Topcoat System)
Price: Stain, $340.00 per pail = $68.00 per gallon; Topcoat, $295 per pail = $59.00 per gallon.
1st coat coverage - 400 sq. ft. per gallon on smooth wood.
2nd coat coverage – 600 sq. ft. per gallon on smooth wood.
Topcoat coverage – 600 sq. ft. per gallon on smooth wood.
1st coat - $68.00 ÷ 400 = $0.1700 X 100 = $17.00
2nd coat - $68.00 ÷ 600 = $0.1133 X 100 = $11.33
Topcoat - $59.00 ÷ 600 = $0.0983 X 100 = $ 9.83
Total cost per 100 sq. ft. = $38.16
When comparing the different stains, don't ask how much per gallon. Ask how much per 100 square feet. Anyone can do this cost comparison.
