PAINTED A SOFFIT IN KITCHEN AND IT BUBBLED AND PEELING ONLY OVER THE NEWLY PATCHED AREA. I USED A PAINT WITH PRIMER IN IT. I SUPPOSE I NEED TO SCRAPE OFF THE PAINT AND USE A PRIMER. BUT HOW DO I BLEND IT IN SO YOU DON’T SEE EDGES?

How much paint is used when using a sprayer vs a roller?

I can see patches of wallpaper backing on walls after they were primed. Is there anything that can be done now? It was not noticeable until primer was put on – now walls look bad.
