I don't always sand primer. Only as paint guy says if it's rough, has brush marks, etc. because your top coat won't 'hide' that kind of thing. I use no lower than 220, sometimes higher. Do like the sanding sponges, they are easier to manage on a job like that versus a sanding block (because you're not sanding the crap out of it. ;) A pressure than amounts to wiping, but not scrubbing. As if you were wiping off your kitchen counter, not scrubbing off a stain on the counter. ;) I always go with the grain with primer, too. Then I use a tack cloth to wipe it down good, get rid of residue, and then paint.

Oopsie, I plan on talking to him. Because I have seen his temper I'm afraid of what he may do, not sure why? When he let me know that the wood grain was going to show thru in the front of the cabinets, said how that wasn't included in the sanding and spackling, I agreed to give him 200 extra, even though DH and I knew it was included, wanted it done right. When he let me know his estimate for painting skylight, sofit and walls didn't include ceiling, he thought it was going to be another extra. Who would expect a job with (new lighting,under counter lighting, granite counertops, carpentry, crown molding, floor, added pull outs, new appliences)not to have ceiling painted? At this point I just want to pay him for what he has done and get him out of my house. If I have to stay home with him while he paints the inside frame with 2 coats of paint, I will sit in the kitchen and watch. Is there anyway of me telling if he did the agreed on 2 coats of paint on the front part of my cabinets? Since he told me several times it wasn't necessary to give 2 coats of paint, I feel he didn't do it,even though he said he did, obviously I don't trust him any more. When he paints the frames he will have to cover my granite, and will also have to take the doors off (inside hindges), do I tell him this, or assume he will do this the proper way? I'm afraid the quality of this work won't be the same, which is why I ageed to the price he gave me. My mistake was looking at his own house as an example of his work, in my home he cut as many corners as he could, in his own home he cut no corners. He has also told me several times that for the "money I paid him and for my doors I could have had a new kitchen", till I asked him never to say that again. He has made other comments, which have done what they are suppose to do, shut me up and get me out of the kitchen! Thanks in advance for your help.

You can but you'll have to pay attention to getting an even, full coat.

No bubbles that I noticed but my tile has a rough texture to begin with so it’s hard to tell. I spent a lot of time prepping. I cleaned for 2 hours, doing multiple steps, then I sanded it to rough it up, then vacuumed and cleaned again, plus I spent hours removing old caulking. Painting was the easy part! Haha. Maybe it’s the roller you used? I used a little mini mohair one. Worked well.
