Basement Reno - Our stairwell was/is painted with lead paint. It needed to be evened out and our contractor covered the stairwell areas that had the lead paint with drywall mud to "encapsulate" it while smoothing it out. Now months later we are priming and spots of the drywall mud is pulling up when I roller it.
Any ideas or help would be much appreciated! I'm not sure how to remedy. They used USG Sheetrock Plus 3 Joint Compound and we are using Kilz 2 All Purpose Interior/Exterior Primer It's been 5+ months since they finished, and wiped all of the walls down before starting.
