Is it bad to paint over gloss latex paint with enamel? THe latex gloss
used on teh trim and doors in the house doesn't resist staining or stand up
to cleaning as much as I'd like, but I'm having a hard time getting info
that I trust re: whether gloss enamel can go over gloss latex without
Most of the information you're probably reading has to do with
painting with latex over oil-based enamel. That's a tough one. If
you're talking about painting over latex with latex enamel, there's
usually not a problem, but the surface sheen can present problems.
The higher the gloss, the smoother the surface and the tougher it is
for the new paint to adhere. That's a particular problem with
surfaces that are subject to frequent contact and cleaning, such as
doors and windows.
Preparation is everything, so whatever you do you have to knock the
shine off of the old paint. That can be done by sanding, wiping down
the trim with liquid deglosser (or adding it to the new paint), or by
using a primer designed for tough surfaces, such as Benjamin Moore's
For painting question, you can do a lot worse than picking up the
phone and calling one of the Sherwin Williams stores. They cater to
contractors and are _far_ more knowledgeable about their products than
anyone in an orange or blue apron.
Thanks, Rico! - that's all useful information; I especially like the
"deglosser" and "primer" idea - I know that one can paint over tile using
the right primer. I also didn't know that about Sherwin-Williams; that's
good to know.
Its should be lightly sanded and as important is be sure its real
clean, areas hands touch absorb oils from hands and reduce the new
paints adhesion. If you were doing the oposite, latex over oil the
latex could fail from any abrasion, requiring removing of latex. Sand
and thoroughly wash it especialy where hands have touched the old
OP said enamel over gloss latex, Gloss latex to me is latex "enamel".
Enamel is just a fancy name, there is no Enamel in oil either. Enamel
just implies a beautiful smooth finish, which a latex cant do like oil
anyway, marketing bs it is. If he is going latex it wont be any
better for cleaning unless he just gets a better paint that cleans
Right, that's what I understand about enamel as well.
The part that I didn't understand in what you wrote was this, "If you
were doing the oposite, latex over oil the latex could fail from any
abrasion, requiring removing of latex." That seems to be implying -
from the word opposite - was putting latex over oil, and that's why I
mentioned your assumption about oil.
Anyway, that's cleared up, and I'm sure that Kris can
fuc...errr....finish it up on his own! =:O
Sorry, confusion for me too, what I meant is I have seen several jobs
where latex trim paint was put on over an old satin oil finish, which
had 20 years or so of kids dirty hands embedding oil into the finish,
where the painter did not clean enough or sand the doors and frames.
The latex would scrape away with a just fingernail or abrasion,
sometimes in sheets. The only way to fix it was to scrape and sand all
the latex that would come off, and clean and repaint the entire
interior house trim. For me interior latex trim paint doesnt go in a
quality house, only in rentals.
