My daughter painted a chair with latex paint. It's been drying for about 18
hours. She'll be taking it to college in 3 days.
If I put the chair in my trailer, which will get much hotter than the
80-85F temp predicted for this week, will that improve the curing of the
paint to any extent? It'll be warm during the day but much cooler (60's) at
night so the paint will experience swings in temp and humidity, unlike the
more constant environment of my house.
More importantly, will putting the chair in the trailer do any harm, such
as resulting in sticky paint? Harder curing would be good, a sticky chair,
well, not so much.

not test paint a piece of something similar, then after a couple
days, see how it behaves. Put a piece of newspaper against it
with some weight on it overnight and see what happens. Meantime,
I'd obviously keep the chair in a warm, dry environment until it
has to go. Probably inside the house, with AC would be the best,
unless is warmer and not humid outside.
The plan was never to have anything touching the chair until school starts.
It would simply be standing in the trailer until we are ready to leave. It
already has a spot reserved in our van so that it will not have anything
piled on it. Once it gets to her apartment the only thing that will be
touching it should be her (hopefully clothed) butt.
I should add that this chair has been painted for many years and was just
looking a little dingy from use. That and the fact that it was used as a
ladder when she painted her room so it had paint speckles all over it. She
put on a fresh coat of paint just to brighten it up.
Her butt didn't seem to bother the paint or stick to it all through High
School, so I'm sure it will be fine going forward. I'll leave it out of the
trailer...no sense in taking a chance.
Sounds like she is ready for college and the poverty that follows :o)
The paint has a film pretty quick when it begins to dry....until it
cures, the liquid beneath the film would probably cause blistering if
left in the heat. I didn't mean that latex is inherently sticky, but
sticks to similar coating with a little pressure. Also takes on
solvent-based stains easily.
She's not just ready for college, she's ready for her junior year at
college. It's her first year living off campus, which will actually be
cheaper than the dorm and a meal plan was. She's just bringing more of her
own stuff with her this time.
But I know about poverty. I've got one that recently graduated from
college, another one just starting grad school and this one who will a
junior. My vacations are spent driving them back and forth and helping them
Buy the grad a truck and tell him to move the others. I'm assuming the
grad is male 'cause my daughters always had BF to help move :o) My son
is now doing college visits....two boys graduating HS next June. Didn't
plan that, but the younger has always been in advanced and/or double
credit classes and is eligible for early graduation. Already has enough
HS credits. The younger is torn between Purdue and a smaller school;
MD? Vet? I'm pulling for something more creative/arty.
Actually, the grad just bought a truck on his own, but not for the reasons
you might think.
While he likes having a pickup, it was more of a financial necessity. He
had a Scion TC while he was in school but now that he's graduated and has
to put some of his salary towards his college loans, he decided to sell the
TC while that loan was still above water and buy a semi-beater pickup to
eliminate the car payment. He was able to do some of the work that the
truck required so he's improved it a lot since he bought it. He actually
talked the seller into refunding about 10% of the purchase once he found
out all the things that the truck needed when he went to get it inspected.
Pretty good negotiating skills!
Since both of my daughter's schools are hundreds of miles away and they
both have apartments, his 10 YO Dakota is not the best vehicle to move
them with. My van and trailer can carry a lot more, and a lot more easily,
than a pickup could.
What kind of latex paint? Glossy stays sticky for months, maybe years AFAIK
which is why I'd never use it for chairs, shelves and the like. If it IS
glossy, a coat of water poly once it is more or less dry will keep stuff
from sticking to it.
Latex paint is simply too soft to provide good service on furniture.
The hand grips on that chair will soon become embedded with dirt from
It would have been better to have painted that chair with OIL BASED
paint if it's still available in your area, or Monamel paint from any
Comex subsidiary selling paint in your area. But, latex paint simply
won't stand up well on a working surface like the hand grips, seat and
back on a chair. It's simply too soft.
No, the higher temperatures you expect inside the trailer won't do any
If you had used a latex FLOOR PAINT, it would have been better because
floor paints crosslink to form a harder and more durable film, but an
oil based paint would have been best.
My advice would be to use some acetone to take the latex paint off that
chair(depending on how much paint there is on it) and repaint with an
oil based paint. If removing the paint isn't practical, then I'd
suggest going to your local Salvation Army, and buying a new chair you
can repaint with oil based paint.
First, it's an armless chair from an old dining room set so there are no
"hand grips" to be concerned with.
Second, it's been used as a desk chair in my daughter's room all through
high school, and it's been painted with the same latex paint that she just
touched up. The paint has held up well, but there was lots of speckles from
when it was used as a ladder when she painted her room.
It's now going to be a desk chair in her off-campus apartment. I'm sure it
will be just as fine as it has been in the past.
There seems to be a misconception in here that latex paints dry slightly
sticky and a result, never fully "cure".
People should be aware that in North American 90 percent of latex paints
are made from one of two different kinds of plastic:
1. Polyvinyl acetate - which you probably know better as white wood
This plastic has poor "blocking" resistance, which in paint-lingo
means that even when fully dry, it remains slightly sticky. PVA resins
are used to make inexpensive interior latex paints and general purpose
primers. PVA latex paints also lose their adhesion under moist
conditions, causing them to crack and peel on bathroom ceilings,
expecially directly above the shower. It is no doubt this slight
stickiness that makes people think that the paint hasn't fully cured.
2. Polymethyl methacrylate - which you probably know better as
This plastic is superior to polyvinyl acetate for making paint in
every catagory except cost. Polyvinyl acetate plastic resins adhere
much better to damp surfaces, and they have much higher "blocking"
resistance, which means that the dry paint won't remain slightly sticky
or stick to itself. PMMA resins are also very much more alkaline
resistant, so primers made for painting over fresh lime based plaster or
fresh concrete will always be made of PMMA resins. ALL exterior latex
paints will be made of PMMA resins.
The idea that some latex paints never fully dry is a misconception.
They all fully dry. It's just that inexpensive latex paints made from
PVA resins will remain slightly sticky even when fully dry.
The remaining 10 percent of interior latex paints in North America are
made from styrenated acrylic resin. This kind of plastic provides good
gloss and hardness, but has poor UV resistance. Such paints are much
more common in Europe than they are in North America.
