We recommend a 5 mil coating over VCT. Any gallon of liquid, be it milk, Root Beer, or even epoxy, will cover 1,604 square feet to a depth of 1 mil. So 1 gallon will coat 320 ft2 to a depth of 5 mils. That's before waste is factored in, waste is typically 10%, so in the real world, on a real floor, 1 gallon of epoxy will coat about 288 ft2 to 5 mil dry coated depth.
According to the Department of Energy 2001 Residential Energy Consumption Survey "...a two-car garage is 400 square feet, and a three-car garage is 600 square feet in size." We'll use the average of 500 ft2 for this example.
500 / 288 = 1.736, so it will take about 1.73 gallons to coat a 500 ft2 area to a dry depth of 5 mils.
BondTite comes packaged in 3 quart kit and 3 gallons kits. It is a 2 part 100% solids product with no extenders like water or solvents that evaporate, so what you buy and apply is what you end up with.
Two 3 quart kits is a bit short, so it will take three 3 quart kits. Our pricing is that a 3 quart kit is priced the same as a gallon in a 3 gallon kit, $75. Due to those price points we could ship three 3 quart kits for $225, or we could ship a 3 gallon kit for that same $225, which is clearly a better deal.
Fortunately with BondTite 1101 it's a case of the more the merrier, so you could take the entire 3 gallon kit and put on a pretty thick layer. ((3 x 1604) / 500)- 10% = 8.66 mils. At a dry thickness of 8.66 mils that's a full 73% more than the recommended 5 mils coating. That would net out to 45 cents per square foot.
Or you could use just 1.73 gallons and reserve the remaining 1.27 gallons of Bondtite for another project. In that case the cost for the coated VCT would be $129.74, or 25.9 cents per square foot.
Besides VCT BondTite also adheres to concrete, masonry, steel, and most woods. Plus it has a shelf life of at least 12 months. So you'll probably find that the leftover extra will come in handy soon enough.
