What should I do about this cracking semi-gloss paint on crown molding?

It's me again.

Yesterday I put Alex Plus in the gaps of my crown molding. Today, I taped off the ceiling and wall and brush painted the crown molding with BEHR PREMIUM Cabinet & Trim Interior Semi-Gloss Enamel. I let it dry to touch, probably more than an hour, and then did a 2nd coat. I noticed some cracks before I started the 2nd coat.

It's been sitting another hour and I just removed the painters tape and I have cracks along the top and bottom edges. I am guessing there could have been paint that wasn't dry when I did the 2nd coat?

Is this paint just expensive junk or is something else going on?

Should I do anything about it now? Can I just put another bead of Alex Plus at the top and bottom seams to cover it up and give a nice smooth transition?

First off, Behr paint is extremely cheap paint do a search on this site and read about the teriible experiances.

You painted too soon, should have waited a day between coats.

Second, painting caulk is never a good idea, caulk shrinks with time and paint will crack, best to get a caulk that matches and do that after painting!

Hmm, I've had good results with their other paints.

The can says to recoat in 1 hour.

But besides the paint, is there a better solution than just recaulking?

And what would the point be in paintable caulk if you shouldn't paint it?

This is why I refuse to use Dap Alex. IMO it is not good a good painters caulk. If you can't find white lightning, go to a Sherwin Williams store and get some decent painters caulk. After you apply it you need to tool it with a wet finger or clean damp rag.

I'm not convinced it is a result of painting on the caulk but who knows.

I'm wondering if gravity made the paint pool in those spots making dry time longer before the 2nd coat, or that maybe slightly too much paint created "layers" which caused the cracking. I think I'm just going to bead some more caulk and see what happens.

I've been reading that lots of people had problems with Alex Plus in the past but recently went back to it and it's been fine.

We have had this discussion many time and have our preferred ways of painting, I always use Alex, but never paint.

I always apply caulk to the finished painted surfaces, and yes at times it difficult to find the right color but I even mix my own caulks to achieve the right color.

When that final bead of caul is installed it then shrinks slightly making a flawless transition between the two materials!

IMO Alex Plus is low quality caulk. White Lightning is my preferred caulk when a specialty caulk isn't needed. Your paint cracking is where you painted over the caulk too soon. I almost always paint over caulk but it needs to have time to dry first.

Just for reference for (my) future is this the "model" you are talking about. It looks like Lowe's carries it.

No. I use this one. https://www.menards.com/main/paint/c...?tid=-1&ipos=2

They also have one that's a little cheaper but I don't like it as well as this one.

I've used the 3006 white lightning for years. it's my preferred caulk.

So I contacted White Lightning via email and they informed me they have discontinued the product XSleeper is recommending and that the closest replacement to it is the 3006. Said more than likely Menards is just going through their inventory.
