I am in the process of treating my new, cured, machine-troweled auto-shop floor with Ghostshield 4500 densifier followed by Ghostshield 8510 sealer after the 7-day cure on the 4500.
The 8510 instructions suggest that UP TO 150 square feet can be treated per gallon using 2 coats as recommended.
I experience difficulty getting a gallon of 8510 to soak into 150 square feet, and I thought that maybe the 4500, by "densifying" the concrete, was affecting the absorbtion rate of the 8510. So I emailed the manufacturer.
The response I got was that, while the 4500 should not affect the 8510 absorbtion rate, for a machine-troweled surface, an acid etch is recommended to improve absorbtion.
In the 8510 and 4500 instruction sheets I downloaded and on the respective containers, I see no such recommendation.
