No one is immune....

I got a couple of doors back due to KA+ peeling after 2 years. Doors were sticky and had streaks on them. Cleaned with acetone, sanded, cleaned again.

Thought I did a good job....

Found out the gunk was hand soap. The doors are directly below soap dispensers. I choose the wrong cleaning solvent, 50/50 mix of water and DNA did the job.

I wiped the wet Surfacer and reshot right away, I wanted a better look at what the product was doing.

is that a normal reaction from paint having soap sit on it?

From what I understand the soap has been getting on these doors for the last 2 years.

Those are fisheyes. The soap had penetrated into the wood causing the Surfacer to react adversely. I don't know what brand the soap is, without the MSDS I don't know what ingredient is caused the problem.

Silicone is the most common cause of fisheyes.

Perhaps they are using an antiseptic soap with a high alcohol content or similar.  Interesting to see the spec sheet on the soap. BW

If it is expected that the exposure to soap would be an ongoing problem, what would be the preferred topcoat?

Not sure right now. The architect will not allow the use of conversion varnish due to VOC's. If the problem reoccurs I'll see if he'll approve 2K urethane.

Mohawk makes a waterbourne conversion varnish. They don't tint but if you need white it may work.
Did the original spec require Kem Aqua or an acrylic?

Had to meet the VOC spec, I choose Kem Aqua. Submitted the TDS and MSDS for his approval.

This is Navajo White, BM match.

Soaps and finished wood products don't play nice together. Prolonged and continuous exposure can and will cause these issues. Most soaps whether hand or dish are designed to cut oil and grease. I learned this lesson with a few wood countertops and people that don't follow instructions. It seems that only the epoxy or very toxic finishes that most don't have access to use can take soap abuse.

Did the artichoke approve the fitting of a soap dispenser where it drips onto a door?

Probably.

Thanks for the thought.

The title refers to me/my not getting it cleaned properly before I shot it. That's on me.

Other than trying to spray the item, how would/could one test it??

Can't. I was relying on experience----epic failure...

LOL, did the same.
I had a door that I thought I had cleaned but there was something that had been absorbed into the MDF door. My primer (wood and wall) went on OK, but when I hit it with the Kem Aqua, and it started to dry it blistered.
Sh!t happens.

Can you use SW wood and wall primer as the primer for Kem Aqua Plus? It'd be helpful if I could use that instead of the surfacer (I ran out)

Thanks

Yes, I do all the time. SW Wood and Wall is a very good primer and reacts well with Kem Aqua plus.

Gotta love when I/we miss a question for few weeks. By now I hope he tried it and found out it works just fine.
