Did my damp basement on LI about 12 years ago, 3 coats white latex drylock on the walls, 4 coats gray drylock on the floor. Treated the floor with the diluted muriatic acid, wire brushed it, mopped and dried it all up. Ran the dehumidifier for a day or two and got to painting. Probably did one coat every 2 days, ran the heat a bit warm to hold about 70 degrees and keep the humidity down.

The basement still looks almost brand new, absolutely dry and virtually no wear, even in front of the workbench where I stand/sit/drag chairs all the time.

Maybe a little overkill, but worked OK for me, and as I recall, the latex drylock wasn't that expensive compared to some of the specialty floor finishes.
