It is difficult to provide such information because it is entirely dependent upon how thickly each coating is applied and the type of support to which it is applied. Based upon our own testing we had the following results on hardboard:

The first coat will absorb into the hardboard and will require a lot more product than the second coat, where absorbency is lessened. In our testing, it took approximately 0.5 fluid ounce of Rublev Tempera Ground to cover one square foot of hardboard for the first coat, which is approximately 250 square feet per gallon. It took less than half that amount for the second coat, which is approximately 500 square feet per gallon. Applying additional coats will require slightly less ground for each coat.
