Painting Epoxy
rlal...@hotmail.com
What would be a durable paint to use on epoxied 6oz cloth over plywood???.
Not too sure if a primer is required either?
On a boat, not in the water for any stretch of time (3 days max) marine paints
seems to be such overkill. They are overpriced and seem to require expensive
primers etc. Alkyd and oil based paints should be as good???
Anyone have any advice or suggestions??
Thanks in Advance
Ron

Can't exactly answer your question for what to use, but acoording to Devlins
boatbuilding book Alkyd and oil based paints are typically not compatible
with epoxy - they do not harden. Using a primer sometimes work and sometimes
not. His rule of thumb is - if it not a two part system it has a better
chance of not being good enough. The paint type he recomends for the amateur
boatbuilder is linear polyurathane (he describes a method for getting good
results using a roller and a foam brush). Since I am going to face this
problem too within a month or so I would like to hear more about this too (a
14' sailboat, will never stay in the water when not sailing).

If the epoxy is completely cured, washed with soap and water, sanded
lightly, then your chances are good that regular marine alkyd enamel will
stick just fine.
(Even if you leave it in the water) But NOT House Paint alkyd enamel
(which I am not sure is available anymore, anyway). And house oil paint is
not the same either!

Latex house paint over latex primer is terrific on fiberglass. I have a 16-year
old skiff painted with latex. While all the rest of it is shabby, the
fiberglass-epoxy butt joint in the side planks is unblemished. Other proponents
of latex are "Dynamite" Payson, Tom Jones (Boats to GO), and Jim Michalak (small
boat designer, builder, and user in IL).

Since you are an epoxy supplier too, Kern, I would be interested in
your suggestions as well.
Thanks,

I wouldn't recommend linear polyurethane to anybody. It is very dangerous
stuff. We use it when people want it but only with piped in air and full
body protection.
I have not found any problem with any paints over any time of epoxy I have
used. Petit EZpoxy seems to be pretty good stuff. It is actually a
polyurethane paint. We tend to use it on glassed surfaces when the owner
lets us.

I have used a glossy latex called Impervex which was supposed to be good for
boats.

I painted my 19 ft sharpie with interlux brightside poly urethane emamel.
This boat is made of 3/8"and 1/2" MDO plywood and covered with 6oz cloth set in
WEST system epoxy. After the epoxy fully
cured (about a week) I WASHED it with vinegar diluted in water rubbing it down
with a scotchbrite pad.
I then thoroughly RINSED it with water and DRIED it with a cotton towel. I then
SANDED the epoxy
so that all of the shineyness was gone. I found that Adalox brand opencoat
sandpaper of 60 grit worked the best. I would recommend experimenting with several
brands to see which is fastest and clogs the least since
all this sanding is very time consuming and unpleasant work. Not all sandpaper
works the same. Stay away from cheap flint paper and expensive garnet paper.
Neither work very well. I used an orbital sander for
most of the sanding but hand sanding was also necessary.
I then DUSTED and RINSED the surface clean again and VACUUMED the surface. I
allowed the surface to DRY thoroughly and closed up the shop so insects and dust
would not be flying in and landing in the wet paint. I then took ONE QUART of the
paint and STIRRED it completely. With a cheap foam disposable roller I applied the
paint to the center of the bottom of the boat (which was upside down) by POURING
some of the paint on the surface and rolling it out with the roller. (in
retrospect I should have started on one end) The surface was full of bubbles
which I TIPPED OFF with a foam brush by LIGHTLY stroking the paint and evening it
out. I systematically worked my way over the boat being careful to maintain a wet
edge
when going on to another area. If it is warm you have to WORK FAST or the paint
will set up too fast and won't lay out properly. I let the paint dry over night
and came back to a nearly flawless finish. I used NO PRIMER and have had no
problems with this paint job at all. It is surprising how well this paint lays out
as it dries. After a few days of drying I lightly sanded with 220 grit paper ,
dusted, and applied a second coat.

Oh , I also wanted to add that I have also used latex house paint with pretty good
results but it is not nearly as nice looking as the polyurethane. Mabey using
latex on the deck of a small boat where it wouldnt be walked
on much would be a good idea since it isn't very shiney and would produce less
glare than glossey marine paint and less expensive too.

In our epoxy refitting operation, we always sand to 220 grit and then
prime with a 2-part universal primer (the yellow stuff - zinc chromate).
This is the same primer sometimes used over aluminum or galvanized sheet
metal.
After allowing it to dry for a couple of hours, one can apply almost any
type of paint, but we like Easypoxy the best. It's reasonably priced,
easy to apply, can be brushed to a high-gloss finish and weathers well.
