First paint project since moving into house. Peeled off original wallpaper from 1979. Scraped glue, sanded, cleaned, and primed all 4 walls. Zisnner Gardz sealer/primer used on all 4 walls. Painted accent wall with Glidden interior paint and primer with darker blue color. No issues. Painted remaining 3 walls with same paint but lighter color. Bubbling and cracking occurred as paint dried. Attempted a second coat and bubbling and cracking remained. Why did this happen and what do we do from here? Any advice is welcome.
