    Polyurea calculation method

    The following formula is provided to assist you in determining the theoretical square foot coverage rate of 100% solids, polyurea spray coating: 1 gallon of material sprayed down @ 1 mil will cover 1604 sq feet. In order to determine material coverage rate, divide the number of mils you intend to spray down, into 1604. This will give you the number of square feet you can expect to get out of a gallon of material. Example: 1604 divided by 60 mils equals 26.73 S.F. per gallon. (An additional 25%-30% minimum for overspray should be factored in the coverage rate estimation.)

    This seems a little more reasonable.

    Joe - Is this the 'hand' applied material?

    Polyurea info

    Hello Bill,

    This is our cost of the high pressure application. The material by itself is just a few dollars, where the additional expenses come into play is in the prep and applicator costs (travel, etc...)

    Low pressure applications "should" always cost less do to the fewer pieces of equipment needed. Low pressure application also does not require the training or experience level that high pressure application does.

    In your scenario Bill, the low pressure application and choice of installer was ideal.

    In situations with different substrates and obstacles such as overhangs, ledges, stone bridges, caves etc... the high pressure systems would be a better choice.
