That is not what we like to hear, Bobby! The coverage of our RockSolid Clear Topcoat Floor Coating Kit is up to 250 ft² per kit when applied to smooth, interior concrete. The concrete pictured appears to be aggregate, rough-finished concrete, which is much more porous than the floated concrete traditionally found in garages and basements. Rough or broom finished concrete will reduce coverage significantly, and can also lead to outgassing of the concrete due to the porosity of the substrate. Outgassing occurs when concrete warms up, releasing air from the concrete. When a coating has just been applied, this will create bubbles in the coating as it cures. To prevent outgassing, we recommend applying in the early morning, or later in the evening when the concrete has begun to cool down.
