To get the best adhesion from the drylock, ALL the peeling paint should be removed and any other areas that are suspect.

Has a residual if used heavy enough.

I’m looking for a pretty good inexpensive test kit that would allow me to find any residue which will help with my decision making.

There is a vinyl siding product that uses adhesive instead of nails, but it has not been in field use long enough for me to consider it.

I am a pastor and adjunct professor who desires to create residual passive income from real estate investing. 

To me, every housing market has deals to wholesale for one aspect of REI or another(for those seeking residual income, to flip, to lease/option). 

If you can find it, there are vinyl plank that have a releasable adhesive already applied to them that leave no residue if removed so you could refinish the floor at a later date should you choose.

@Steve Haight I was just meaning to add that there is virtually no buildup or residue from smoking the marijuanas.At least ... that's what I've heard.

Cash-Flow is the residual you keep after paying the bills monthly.
