Painting over Semi-Gloss
Frank Hagan
My new (to me) house has semi-gloss paint everywhere . . . including
the ceiling. The walls are textured in what I think they call "knock
down" texturing, which makes it impossible to lightly sand them for
adhesion of a satin or flat wall paint.
Is there another alternative to sanding to make flat paint stick to
the semi-gloss?

Frank,
You need to buy a deglosser and coat your walls (etc) with it. Afterwards,
the semi-glos should
make the paint stick to the semi-gloss.
The deglosser ( in my experience ) had to be applied with a sponge or clen
towel. I am sure that you
can brush it on though...
Good Luck!!

Why not use TSP? Cheap and fast.

Frank-
First you should determine what kind of paint, alkyd or latex. Alkyd paint is
rarely used for walls nowadays. We use it in Kitchens, baths, workshops if the
owner expresses a big concern over durability. But I'd say we use alkyd on
maybe 1 or 2 walls out of 100. If the walls are latex, clean them with a mild
mixture of TSP if dirty, and paint right over the semi-gloss. "Nothing sticks
to latex like latex" is an apt phrase that comes to mind. There are several
ways to check to see which kind of paint you have. Let me know if you need some
tips.

TSP is an excellent paint cleaner, but does little in softening the old finish
for better adhesion of the new finish.

Its latex . . . there's a small can of "touch up" paint in the garage
(something the painting contractor left him, from the looks of it ...
its something like a 1/2 pint.)

Thanks! I didn't know if the TSP thing worked with the newer paints .
. . when my parents owned apartments 20 years ago, we used TSP instead
of sanding.
The walls are pretty clean, as the paint is new. Will a satin or flat
latex stick to it without the TSP treatment?

Uh, Paul, no big deal but then why do you post the above right after
you post the below?

I'm a little confused...1st a discouragement on the use of TSP for
this app and then a recommendation for it!
Whats up?

Sorry, I should have included the tips to ID which type of paint you have. It
was time to go to work, so I cut it short.
1. Sand an area with 120-200 grit paper. Latex will cut easy, probably gum up
slightly. Alkyd will resist sanding more than latex. Easy to tell side by side,
not so easy by itself without experience.
2. Dampen a cloth with No-Sand, (deglosser) rub an area with it. Latex will
soften very quickly, usually within the first 3-4 strokes. Alkyd will take
several minutes to soften with rubbing.
3. Use denatured alcohol instead of No-Sand. It will soften latex, won't do a
thing to alkyd. Quite a bit slower than No-Sand, but it works.
4. Oops, this should have been first. Look around the house for the old cans of
paint and look at he label.
4. If not sure, cut a swatch off the wall and bring it to a _good_ paint store
you are familiar with. They should be able to tell you.
Hope this helps.

Danny-
Well, I guess it does look a bit confusing. The thread originally was about "Is
there another alternative to sanding to make flat paint stick to the
semi-gloss?" One reply was "Why not use TSP? Cheap and fast." I then replied
"TSP is an excellent paint cleaner, but does little in softening the old
finish for better adhesion of the new finish." What I thought I was saying was
that TSP will clean the paint which is the first step in insuring a good bond.
However, if the semigloss Frank was refering to was an alkyd (sounds like he
thought it was, but it turns out it was latex), he sounded like he wanted to
prep the semigloss with another step other than sanding for proper adhesion.
This TSP won't do by itself, but it is the start of any paint job which is
dirty. The second poster sounded like he was recommending TSP by itself. The
way I was taught was to clean the alkyd surfaces with TSP, sand and wipe down
with a good de-glosser and prime.
Hope that makes more sense this time around, although reading it is getting me
confused!

Without a clue such as a can of touch-up paint, how do I tell if a
semi-gloss is alkyd or latex. I'm about to repaint the kitchen with a
semi-gloss latex, and it sounds like I will have to do some surface prep
if it's alkyd...
Thanks

Someone forgot to tell that to the paint in a house I once owned; I
found that if I scrubbed enough with TSP, I sometimes went right
down to the wood.
BTW, there is TSP which is tri-sodium phosphate, and there is
TSP-brand phosphate-free detergent. I prefer the former, and
consider the latter to be borderline deceptive.

Carrie, please reset your newsgroup reader to mark this thread as unread. The
whole process was covered earlier in the thread. It's a bit involved to resend
it.
One more item to be added here, and it sounds like the easiest for the DIYer-
Greg from Quality Painting (g...@prcn.org) emailed the following suggestion to
me-

I'll have to try some of those out myself.

Topher-
Yes, TSP will flat eat up paint and especially old varnishes if mixed strong
enough or the paint or varnish is "dead" (dried up, pretty old). But you have
to let the cleaned surface dry overnight before priming. This negates the
softening effect of TSP in these cases. Even when using a deglosser, it's
reccomended to prime the area you've deglossed within a half hour or so.
