In an effort to get a perfectly smooth painted (latex) finish on a
door, I applied a water-based sanding sealer (Olympic) prior to
painting. The stuff dried within seconds of being applied, at least
enough to prevent it from leveling. Trying to sand it level brought me
back to bare wood on most of the door.
Multiple coats did result in a beautifully smooth finish on most of the
door, but there were still some ripples and rough areas that seemed to
emanate from the very first coat.
After sanding back to bare wood, I'm reluctant to try this stuff again,
but I'm thinking it would level quite a bit better if I could slow the
dry time. Will Floetrol help?
Thanks for any thoughts.

mix it with a retarder, most sealers have thinners and retarders ,the latter
to extend the drying times
In addition, yer younglings will bang that perfect surface up soon
enough. j/k
First off, I assume you are NOT prim/painting the thing while it's
hanging. Get it on some horses. Priming is a must for fresh wood.
Never used sanding sealer myself. As previously suggested use a
shellac product, get at least 2 coats Seal Coats on er. SAND WITH DEAD
FLAT BLOCK 220. Apply another coat SC. Sand with block 320. Add a
good bit of Flowtrol to yer latex and apply 2-3 coats paint sanding
LIGHTLY between coats w/320 and block. Totally pro look yet will still
reveals tasteful brush marks which resemble a grain pattern assuming
you know how to brush a door the RIGHT WAY. If not DAGS. Good luck!!!

Well, I had hopes. :-) Lots of articles in the archives where people
promised that using the foam rollers would provide a glass-like finish.
I'm beginning to think that must only be true with oil paint.
Actually, my first coat is pretty darn smooth, just too thin. After a
couple of coats, it's no longer smooth.
I have one place on my wall where I applied a skim coat of joint
compound and the paint is very smooth, so it seemed plausible that the
smoother the original surface, the more likely the paint would be
smooth. However, it may be true that a coat of latex paint doesn't
provide the ideal surface for another coat to level.
If these experiments convert me to oil paint for some applications,
then at least I'll go into it knowing where the real limits of latex
are.

No younglings! :-)
<<Get it on some horses. >>
Been on horses for about two weeks. <sigh>
<<Priming is a must for fresh wood.>>
It was actually stained, but didn't seem to have any finish on it.
Regardless, I used Zinser's BullsEye 123.
I will try your suggestions. I had not used greater than 220 on the
sanding, but I did have Floetrol added to the primer and topcoat.
Thank you!

Here's a thought. Hold the can up in front of your face, at eye
level, with the front of the can facing you. Very slowly, and very
carefully, turn the can around so the back of the can is facing you.
Slowly read the words of wisdom thereon, from the manufacturer; repeat
as needed. If that doesn't help, there should be a 1-800 number
somewhere on the label. That number is there so you can call the
manufaturer and ask your questions. At this point, you set the can
down, with the front facing in the direction of your choice. Then you
call the 1-800 number, on the telephone, and ask your question(s). No
prob.

Sealcoat is a 2 lb. cut.

I use BIN (pigmented) or Seal Coat (clear) under just about anything,
including latex. Neither has ever let me down, and having to keep
only two products around simplifies many jobs. Both are excellent to
sand, work in a wide temperature range, are inexpensive and easy to
obtain.
Since they're shellac based, you don't even have to clean the brush,
if you dedicate them! <G> Simply drop the brush in alcohol before
use to soften it up, and off you go. I also keep spray bombs of BIN
and Zinnser clear around for small quicky jobs.

FWIW . . .
I grew up with oil fired 'Hot Water Radiator' heating. We were ALWAYS doing
something to the house and basement was storage/shop/playroom,etc. There
were no 'water based' finishes.
'Fast Forward' about 30 years. A few years after I got married we bought a
house . . . with 'Gas Fired Hot Air' heating, etc. Needless to say . . . my
'skills' were to be applied. When I used the OIL based finishes I was
familiar with, the entire house developed a subtle, odd odor. My wife, the
chemist identified it . . . "burned hydrocarbons". From the few molecules
that got into the air and came in contact with the tiny 'pilot lights' in
the rangetop and water heater!! So began my research into 'Water-Based, 100%
Acrylic, . . . etc' finishes. And a frustrating time it has been !!
My last 'adventure' was finishing a wooden replica of a 17th Centry ships
anchor. It took about 3 months and about 12 coats of grey primer and black
finish coat. The basic problem was that when I did the 'between coats'
sanding . . . the 'coat' would peel off !! Even after 72 hours of 'drying'
in a 'room temp' environment. {and with different concentrations of
Flotrol}. I finally called the paint manufacturer . . . and pushed through
untill I got directly to the Technical Lab.
It turns out that the 'Acrylics' need a LONG 'cure time' . . . 14 DAYS {or
longer, depending on the temperature & humidity of the environment}!! This
is similar to the epoxy I work with - but they only need about 72hrs for a
'working cure'.
In your case I would do a few experiments. Take a piece of '1x6' paint it
one side with the primer. Then {starting at 3 days} sand a 6 to 8inch
section, then sand another section the next day, etc., etc., untill the
board is 'filled'. Then put on a topcoat and repeat. To be exact . . .
follow whatever sequence you on your door, etc. While this may take time,
you will then KNOW, EXACTLY what WORKS for YOU. Take notes, and you will be
able to repaat the results . . . every time. Even though you may find
variations . . . in you change brands, if the manufacturer changes
formulations, etc. . . . you'll know WHERE to start for that specific
combination.

So when/if you get a perfectly smooth surface, how are you going to get
<ugh> latex on perfectly smooth? Not with a brush or roller, probably
not sprayed either.

Have read that Zinsser doesn't recommend Seal Coat as top coat/final
finish. Have NOT read why not.

I haven't used the BIN, but I too swear by Sealcoat. I even use it as my
shellac finish. Takes a few more coats since it's a one pound mix, but
goes on flatter.
