So what caused this failure?

Let's relax and talk paint!

p.s. There are some factors that I'm not disclosing at the moment, to keep people interested and participating!

looks like the paint has not keyed to the substrate properly. Is that a metal doorframe ?

Krud cutter is your friend for pre paint prep.

Yes, metal doorframe, and grey factory primer showing.

1. Latex over oil is a strong possibility.
2. Lack of primer prior to finish coat.

I would have to see it in person to be sure.

I'm gonna guess Behr applied by a hack in jeans who left his shoes on in the customers house while he was putting the screws in the plates pointing at different angles and painting the doors without removing the handles.

The failed finish looks like an Alkyd. The Shop primer is probably an oil base zinc primer.

couple of things:

1. Primer dried too hard and wasn't sanded prior to finish coat

2. Application of finish coat in freezing temps and then warmed up created rapid expansion and contraction

3. Door was exposed to a pile of snow

4. Owners hairy back scraped away paint while scratching it on door frame

 

[Steve Richards]

Someone closed the door, and their dog wanted in. Larger dog, maybe a German Shepherd

or

the cleaning lady used Pine-Sol on it before it was painted

Those are my guesses.


Is there gonna be a prize for the winner on this, TJ?

Just clear coat it and call it a faux paint job. All done move along.

Great analysis,:thumbsup: but you failed to mention what the chemical re-coat technician did with the lid after opening the paint can.

Anyone applying finish coats over that chitty factory primer coat deserves this pain. Fun game cant wait to hear the suspending facts

I think the paint failed in an attempt to distract ones eyes from the nasty azz carpet.:blink:

 

[Gough]

In Section 9900, there are often warnings about the shop coat/factory "primer": needing to sand it, re-prime, etc., etc. Like much of that section, those warnings seem to be widely ignored.

I did a scientific "hand over the surface to get a feel for the tooth" experiment, and there was none. The surface was smooth as glass.

This is a basement of an institution built in the mid 20th Century. There are tunnels down there. It's spooky at night.

Bingo! The shop coat is really just to keep the frames from rusting between the plant and the jobsite.

Huh, we go over shop primed metal cases daily, never had that problem.

I like the pine- sol answer:thumbsup: or some kind of cleaner.

The frustrating part is that some are just fine, but a bunch are not...and the PCs are responsible in any case.

I think a lot depends on the manufacturer: what shop coat they use, how they store their inventory, and how often they turn it.

 

[robladd]

I believe the mastic that was used setting the tile contaminated the shop primer causing poor adhesion when top coated.
