Blending new mud over painted walls/ceiling

I need some of your guys tips to blend in new mud repairs and make them look perfect over painted walls in ceiling. For instance; recently I did a ceiling project and one joint showed through the paint, so I primed the area first then applied mud to help the situation, then sanded and painted 2 coats. Problem is it looks almost worse because I can see the new spot I have mudded and sanded smooth and the rest of ceiling looks painted.

Is there any tricks to make it blend in perfectly for future reference? It's very frustrating. Would love some tips.

Thanks

You can always use a lower grade prime the finished chalky before applying mud . The paint itself a a smooth or semi smooth finish will make a sheen look over your patch and the other idea is use a stain blocking primer which will give a more consistent colour before applying ceiling paint which I assume is. Flat white.

I think understand what you're saying. First, it sounds like the taping wasn't done right over the joint, causing it to show through the paint, that's either not enough mud on top, or not enough underneath. The "smooth spot" is generally because drywall paper is tackier than dried mud. Just do an extra coat or two of paint on that spot. Hope that helps you.

The paint is not the problem. First apply a skim coat of mud just barely heavy enough to cover the imperfections, make sure to go 1 inch wider than the problem area. Sand, then apply another coat (1 inch wider again) this time wipe it all off. This is called a tight skim, it will cover any air bubble from skimming over paint. Sand when dry with 220 grit. Use a 500 Watt light to identify ridges, and sand them out BEFORE painting.

Hello,

More mud is needed but you have to fan out from the joint at least a foot from each side if not more. Make sure there is tape on the joint first. You will need at least 2 light coats maybe three. That will repair the problem.

Good luck.

Prime the new patch with an oil based primer like kilz with a roller to create a texture on it. Get someone to hold up a light to shine across the ceiling so you get the texture looking right and you don't leave any streaks or globs.
