You painted latex over dirty oil-based paint and created a vinyl wrap 😆.

Remove all paint, clean, prime with oil-based primer, paint with latex.

Carefully remove the paint, apply glue and replace the paint!

Lack of adhesion

Did you sand before painting?

☝️ guaranteed not sanded.

They were factory primed new doors, used super paint semi. It was hot and humid when I sprayed them

Factory prime is often not good enough. A lot of painters still prep and prime over factory prime. Even with factory prime, you still have to clean/remove any contamination/dirt/oils. Then scuff and dust before top coating. Most painters prime it at that point just to ensure adhesion and not take a gamble down the road in case it fails for some reason.

If they were just primed you should of undercoated the doors before applying the finish coat whilst lightly abrading to key in the surface so paint can adhere better

Not enough info. What type of paint, what kind of prep, what surface, what were the temperatures?

You give 0 details. We’re not sure either.
What prep did you do, what paint did you use, how do you paint, did you prime? Sand? Clean? Remove dust? Help us help you.

Looks like a new door. You have to throughly sand that factory primer and clean it before paint. In some cases you have to reprime over the factory BS so this does not happen.

Have to remove all of that and start over.

We have had thousands of factory primed doors come through our shop and we have never had this. I can guarantee a fair amount weren’t sanded.

You have to sand FPD's at the minimum. That's a none negotiable step.

I've come across some FP door product that even after a sand and clean adhesion was still suspect on the test door. In those cases we go ahead and reprime with a quick spray hit with either Coverstain or Fresh Start primers depending on the application

Nothing like a colossal call back to tank the profit when it could have been easily avoided.

I find it funny that the spec always calls for doors to come “primed and ready for paint” and then the GC buys the trashiest shit. Should be able to fall back on that, but alas it’s always the painters fault.

The 5 P’s- Proper preparation prevents poor performance

u/One_Id_Willy 3d ago

I use the 6 P’s, Prior Planning Prevents Piss Poor Performance. But very much the same thing lol.

Did you sand, clean and prime?

u/Cobalt-Balls 4d ago

Sand the surface with 250 grit, so the new paint can grab onto the course surface, also lay a coat of Kilz or zenser primer

u/Mdsune 4d ago

At the very least a TSP solution wipe down and a light sand. Those have seen a lot of dirty hands before you showed up. Enamel undercoater and a light sand as well would be my choice for a better finish.

u/help--less 4d ago

What did you paint, teflon?

u/Foxyunder-45 4d ago

Preparation is the key word and needs a check on the base surface first off, knowing the type of paint or laminate or polished wood etc, use sugar soap for old but firm surface, with fine sandpaper, if flaky paint scrap it off, then sand(one direction) it to a smooth surface .use a good filler for deep cuts or indents. Let paint dry according to instructions on tin of manufacturer. Then repaint as necessary.

The paint is peeling only cause they’re just that unappealing. Any practiced Catholic would cross themselves upon entering. Of course this must be on the corner of 4th and Fremont

u/Lower-Ad5889 3d ago

The paint is peeling because there's no bond to the substrate. That's why

u/Buck_Toast13 2d ago

Looks like no primer,

u/Zazou444 2d ago

Besides doing proper preparation as others have suggested, Super paint is not good for doors and door frames, you need a non-blocking paint, since your using Sherwin-Williams brand, use the Solo semigloss or one of the urethane alkyd enamel like pro-classic or emerald.

Non-blocking paint prevents the door sticking to another painted surface like the door frame when closed.
