I painted a birch plywood desk work surface with latex CIL SMART3 WASH &
WEAR Kitchen & Bath paint http://www.cil.ca/en/brands_smart.html (at the
suggestion of the HD paint guy) as he said it would give a durable washable
finish. The surface was first lightly sanded and primed with Kilz2 and then
two coats of black latex.
The issue I am having is that the paint surface seems to remain tacky/sticky
when items are placed on it then moved later. The surface is dry to the
touch but items do stick after a few minutes. From reading I understand
this may be an issue with latex paints and known as blocking. It has only
been 3 days since the final coat was put on so perhaps it is just an issue
of waiting longer for drying?
Is there anything I can do to get rid of or reduce this beyond repainting?
Will it go away after a week or so or will it remain for the live of the
paint? What about waxing or using talcum? Since the is a semigloss black
finish I wonder if talcum would cause a mess. For wax what would be the
bets to use?
Any other suggestions?
I think what you are seeing is "blocking". Very common with latex paint.
Some people have reported having the problem for as long as five years.
As paint can take up to a month to cure (not just dry) you might want to
wait that long before you give up and strip or refinish the item. Sorry, JG

You want a "blocking" paint. A lot of latex paint never really
"dries". A "blocking" paint will cure as a solid and you won't have
that problem. Ask someone at a real paint store for paint for the
BTW, paint isn't the best idea for a deck.
Home Depot strikes again.
The tackiness is because the paint isn't yet dry and won't be for
another month or two. Eventually, the sticky goes away. You can make
it go away now with a coat of water base polyurethane varnish. Which
would also be a *much* better finish for a desk than latex. I'd think
talc would work but not good on black. Don't know about wax, maybe.
Johnson's Paste wax is a good one.
Thanks, that is about what I thought. Hopefully it will go away, I just
need a short term solution I guess for the next month or so as I do need to
make use of the surface.
Will a polyurethane finish go directly over the current surface as is? I'm
a bit concerned about how well it might stick as the current paint has
Teflon in it for easy cleanup. If so how long does the polyurethane take to
dry before it could be used?
Perhaps wax is my only real easy solution for now. Anything specific to look
for in a wax for a latex surface such as this?

It may or may not go away. Give it a couple of weeks and see what
happens. Looking at the paint you used, it's from Imperial Chemical
Industries, it's got Teflon and ceramic microspheres, it's won several
awards, so I don't think that the quality of the paint per se is the
issue. Was the piece above 70F and the humidity below 50% when you
painted? If it wasn't, then try warming the room and keeping it warm
for a week or so. May be too late but it won't hurt anything.
If you decide to try waxing it, Butchers Wax and Johnson Wax are both
good, silicone-free products with a long track record. If you can't
find either of those, go down to the local bowling alley and ask them
what they use and where to get it and it will probably be OK.
If you want a quick and permanent fix, find a paint store (not a store
that sells paint, but one where paint is their primary business) that
has a good brand of waterborne polyurethane, get some mixed in the
color you like, and overcoat with that. Should be able to get several
coats on in a day and the next day it should be ready to use. Make
sure you tell them what you are about so that you get the right primer
Thanks. The temp was around 68-70F, was painted in my basement which is
very dry and humidity is fairly low. I also ran the dehumidifier on full
the days they were painted and the day after as well. Perhaps I should just
keep it running full in the room with the painted surface.
From what I can see about the paint it is suppose to be good quality and
fairly durable, it may just be that it needs more drying time is all at this
point. I have a few things on it now (LCD monitor, keyboard, mouse, lamp)
as I need to use the surface but will try and keep most of it clear as long
as possible. Nothing is sticking yet to the point it is removing paint, it
just seems very tacky when anything is moved and I don't want to mark it up
if I can avoid it.
Depends on the underlying issue. If the paint isn't dry it will take
longer to fully dry with coatings on top. Wax paper or wax could leave
impressions from heavy objects if the paint is still wet. Possibly use a
de-humidifier and some heat.
Others here seem to have more experience with this issue. I'd consider
the paint defective, I don't have that problem with the paints I use.
In my experience with paints, oil based take longer to dry but aren't
tacky after 4 days of drying. Oil does take up to 30 days to dry fully,
and I try not to apply further coatings before fully dry if project time
permits. Water based can be non-tacky within 30 minutes, fully dry in
48hrs. I have limited experience, usually airbrush or art, I generally
use shellacs and waxes on woodcrafts.
Thanks. It is not tacky to the touch like a semi dry paint soon after
applying, it is just tacky when something of weight is placed on it for a
few minutes. No paint is coming off, it just seems a bit sticky on moving

Like I stated previously, not much experience.
Recent project - display cabinets for gallery/store. Original finish was
wax over shellac, de-waxed, painted with oil-based paint. Not tacky with
heavy objects after long periods of time. Sun exposure.
Past project - small dresser converted to shop cabinet, quick strip and
sand, painted with latex paint, not tacky with heavy objects after long
periods of time. Occasional damp, high humidity, garage. It was for the
shop, I had free latex and I didn't care, otherwise I never would have
chosen a latex for a high humidity location.
I had to look it up, never seen the problem. Wax or oil-based paint
finish was recommended. I'm just guessing here, but the thinness of coats
applied with the airbrush are probably why I haven't experienced it.
From what I read the problems is one or more of;
bad surface prep
too thick of application
Try drying first then wax, otherwise after 30 days if the problem still
exists I would strip and re-paint. Quick covering problems often doesn't
work for me. YMMV
Only issue is that if you have to recoat it later you have to get the
wax off--the ones I mentioned should clean off with mineral spirits
and leave no residue. What you want to avoid is car wax with

Despite what others have said, the tackiness NEVER goes away. It just
takes longer and longer for items to stick. I've got some storage
cabinets that are about 10 years old and if I leave something sitting on
them for a month or more they stick.
My suggestion would be a barrier coat of dewaxed shellac and then poly or
varnish over that. If you use super blonde shellac and water based poly
it shouldn't change the color much.
Since it is a major brand, sugest you contact their Technical Service
