I have been repairing a piece of wood directly under one of my windows
with Elmers epoxy and today got to the point where it was time to
caulk. I used silicone caulk and wondering if it's a bad choice. I
applied this around 12:30-1pm and as of 830pm it is still very wet
feeling like it doesn't want to dry. Is this normal??? Is GE a good
brand? I asked because I also had trouble under another 2 windows but
in those 2 examples the caulk broke up and looks burnt after aprox 1
year. They were both the same brand (GE Silc II) only difference was
I need to finish this up as rain is coming Sunday night. Should I get
something else if not dry by tomorrow morning???
No it doesn't smell but I just went outside and checked the date codes
on both the black and the white tubes. Hard to read but it looks like
both say 9/9 which means it would have expired 3 days ago. (It could
have been 4/4 but I don't think lowes would have sold something that
old..as I bought both last year)
Ok thanks for the tip on Dap. I have used that before with no
problems but I didn't use it this time as it is not pure Silicone. I
had read on the net that pure silicone is supposed to be the best but
starting to think otherwise.
If not dry by tomorrow morning will rip it out and go with the Dap. I
just checked and it has no expiration date listed at all. Tube says
part Silicone part Acrylic
Thanks for the help,
I had trouble specifically with GE Clear Silicone Caulk, which I believe was
called something like Silicone II. It never cured, never gave off a vinegar
smell, and was within its date code.
When I posted on this newsgroup, others warned me that GE had bad batches of
this caulk, and I apparently had purchased such a bad tube. I removed the
(never cured) GE, replaced it with another brand, and the problem was
Thank you..that is what I have (GE Sili II) and it sounds like the
The black colored GE II (what I used in 2 other windows about a year
ago) did cure as far as I know but later broke apart and now looks
like it was burned.
No more GE...Dap from now on...
It's a primitive rundown on the things that Lowe's sells. It doesn't mention
polyurethane caulk. I used to be able to get polyurethane caulk at Lowe's and
HD, but not for the last year or 3. Now I go to a construction supply place. I
can count on this stuff to work and last. Why mess with silicone?
There is a discussion of polyurethane caulk ner the bottom of
I use silicone caulk where I don't want to caulk for another 6 or 7 years.
My pool, sky lights, and flashing. Otherwise I use latex. I buy them new
then throw away what I don't use. I donno...never had a problem. Has never
been a real big issue in my house.
Do a net search and you will see others having problems with the GE.
Seems hit or miss but not nice if you get one of the bad tubes.
I did one for GE.....And then Dap. About the same
Personally, I think a lot of the problem is expired caulk. Could be storage
problems too. I kind of doubt there are huge amounts of bad GE caulk but....
I'll try some polyurethane caulk. Not sure if I haven't already.
Thanks for the link. I went to Lowes this afternoon and looked around.
I could have missed them, but I also could not find any PolyU based
caulk. I have used the poly glues for making retaining walls and can
say those work great. Anyway could not find so I came home with
colored Alex Ultra 230 and yes broke down and gave the GE another
chance. They have changed the look of the tubes so maybe I did get 2
old tubes. I will test the GE and if it drys will use it for the hard
to get to windows (I live on a hill and will need ladders for 2 of the
windows) and use the Alex for everything else. Then sit back and see
which holds up the best.
whatever brand caulk you buy be CERTAIN its marked paintable........
some types dont allow good adhesion between caulking and
as a friend found out he caulked his entire wood sided home, caulked
everything, after priming.
boy was he unhappy when not even primer would stick to the caulk:( the
wood siding was in bad shape, so he primed then caulked everything..
then he went back and to prime the caulking areas and :(:(:(*
he ended up having his home vinyl sided which is what his wife wanted
to begin with..............
he wasted the better part of a summer, scraping, sanding, priming,
this was a evening project after work and weekends.
the caulk was clearly marked not for painting...........
Thanks...I feel for your friend as I *hate* having wood siding around
just 2 windows and can only imagine the hassle if my whole house was
siding rather than brick.
I plan on doing vinyl or something as soon as I am in better shape
money wise ..
