Any oil based exterior paint will cover latex and stay on without any
pre-treatment.
I also paint furniture (some of which will be on HGTV this fall) and
even though I had rather see finished wood, I will paint it if it'a
what the customer wants. Painted furniture sells.
In order to rest my case and the only wat to prove my point is this:
Paint a piece of wood with ANY latex paint...two coats, then paint a
piece with 2 coats of ANY oil based paint or oil based enamel. Then put
2 coats of oil paint over the latex and 2 coats of Oil base paint over
the latex (water base). After the two pieces are dry, see which pain
will scratch off easily.
It's like painting water based paint on a mirror when you paint it over
the slick oil based finish...see how long it will stay on a mirror.
YES, you can put oil based paint over water based paint without any
pre-treatment. Call Sherwin Williams or Benjamen Moore.

Please provide the name of ONE nationally-available exterior oil-based
paint whose labelling allows application over a pre-existing latex
topcoat without any pre-treatment.

Thank you.

PS: I have no idea why anyone would even want to fool with oil based
paints to begin with when they make so many nice exterior water based
polyurathanes that will protect decks etc...and there's also water
seals that are water based. The clean up for oil base is far too much
trouble. I even use a satin finish latex for woodwork...IF I want wood
painted instead of stained. If stained, I use Johnson's wax for the
final finish, but satin poly or gloss poly in water base can be used
over water base stains.
Sorry some don't like my answers but they have come through 50 years of
experience that started with pamphlets from the paint stores over the
years and advice from BIL who has benn in the paint business 40 years.
I have been painting for 64 years. When in doubt, just go ahead and do
it your way.

I have an exterior set of stairs with cedar treads and risers, and I'm
having trouble getting them to hold a coat of paint. (The rest of the
structure is painted battleship gray so the stairs need to be painted
also, or it won't look right).

These stairs see full sun, wind, rain, snow, and heavy foot traffic.

I have completely disassembled the treads and risers and sanded down to
bare new wood, and stored in my garage so it stays dry while I try to
figure out what to do.

What would you recommend? Please give specific product names and any
special application suggestions that might help make this project
successful.

Thanks.

Ether, if you are really serious (sorry, I thought you were following
Chuckler in the jokster part of the posts) I would call a local paint
store and ask them about painting wthe steps with a good marine paint.
It's expensive, but well worth the cost. It's what they use on boats
and stays on for year in the water. They might have a better, less
expensive option for you, but that is one solution. Any paint store
anywhere will be able to get it for you even if they don't normally
carry it.
I built steps to my atrium door and I painted them with ltex paint and
the put 3 coats of clear polyurathane on them. It's been there 2 years
but will need another coat or two next year. I will also add some
Thompsons water seal..that's what I used in a cracking concrete
fountain 2 years ago also and it still holds ater just fine. There are
so many good products out there and your paint dealer knows them all.
All I know is what works for me. I didn't mean to sound sharp with
YOU....again, sorry! Good luck with your project.
