putting latex on vinyl shutters
I gave a bid yesterday for vinyl shutters. They have previously been painted with oil. They are really chalky. I have always used latex superpaint for these. Homeowner is really afraid of using latex on the shutters. Opinions. I have done lots of shutters with latex and no call backs at all. How many of you would put oil on these?

Not that I don't agree with that statement by itself
But there's already oil on them
Why wouldn't you keep them oil?
(not arguing, just don't know why)

It's just strange. I have gotten in the habit of switching all exterior and interior oil to latex. Oil paint does not hold up against mold and mildew. Acrylic Latex is built to withstand it.

For painting over exterior oil paint, I have been told both:
1. It needs to be primed.
2. It does not need to be primed.
Some old painters have told be that exterior oil is soft enough that the acrylics will stick fine.
Standard paintstore advice is to prime first, but often they need to give the most conservative advice possible to cover of possible DIY errors.
What is your take?

My take is the same as the paintstore advice, like I have said. Prime first. Priming is a safeguard that is so precious. I don't take chances, I cover myself every chance I get. You never know how the current substrate will react to putting a finish product straight on.
I follow manufacturer recommendations and I suggest every painter do the same if they are warranty-ing their work. The manufacturers know the products they sell and have tested them tried and true.
Fact is...people don't like to be told what to do. The funny part about it is that usually it's good advice, but our own emotions get in the way and we get on the defensive. Fooey on that...I listen to reputable advice. It keeps me humble, safe, and able to sleep at night.
(On a side note) I can't count how many times an 'ol timer has told me to do something dangerous and incorrect. For instance, insisting that I scrape and sand a 50ft. section of soffit and fascia containing years of lead. I am not about to lose my company because some old fart used to scrape lead or heck...even apply it, no mask no respirator. That is simple ignorance, not wisdom.

Normaly i would say to put oil back on top of it, but since it is outside i will side with Rich on this, prime, then an acrylic waterborn enamel for the topcoat.
Also i would tint the primer to the topcoat color.

Years ago standard paint store advice was to put latex right over oil.Painters found out pretty quick that it didn't work.Best to oil prime first if you are going to switch to oil.

Other than potential adhesion issues, what are other problems on exteriors that are a sign of acrylic over oil with no primer?

How about selling them new shutters? You can get them for small money in a ton of colors (colours in Canada).

The reason today why oil primer is recomended over oil when switching to acrylic is that the new acrylics pull and tighten when curing and can pull oil paint off the substrate if it has been on there a while.PDCA was recomending oil primer long before the manufactors woke up.

I wouldn't go directly over oil with an acrylic unless you are using a product specifically designed for this type of application. I'd still prime it first just to be safe. I have a DTM from Sampson that adheres extremely well to glossy oil finished without priming. I've never seen it fail to do so, but if I were to use it, I'd still prime with an oil primer just to be on the safe side.

There is a specific primer for vinyl shutters. Some of the shutter manufacturers recommend it. It is called Plastic & Vinyl primer. Should be available through SW.
