I used 3 coats of the latex-based DryLoc on mine before I remodeled
the basement. It's bone dry, but I had no seepage whatsoever prior, I
just dry-locked it to not have any chance of musty humidity odors. It
might hold your seepage for a year or so, but if you have seepage now
it will be back someday dry-locked or not. Small seepage like this is
easily fixed with an injection that a basement waterproofing
contractor can make from the outside. And that is the proper thing to
do first. But I highly recommend using dry-lock before putting up
walls in any basement remodel.
