Re: Another MDO question
If I was doing it and had a table saw, I'd be tempted to rip some strips
of any old half decent, gluable wood and glue them on the plywood edges.
Then I'd just use latex house paint.

I have been using epoxy on the edges of MDO and it seems to penetrate and
seal the raw edges nicely.

Latex primer and house paint will last forever in this application.

Thanks Dave. All good points. I like the bondo idea, never thought of
it. I'm leaning towards a brand name acrylic latex primer and finish
so that seems in line with what you said.

it. I'm leaning towards a brand name acrylic latex primer and finish
so that seems in line with what you said.

Hi Bryant,
At Arbor Woodworks, we have done several similar projects. We have
treated the raw edges w/Bondo (polyester based automotive filler
compound) before painting. The specification - received from the
architects involved - seem a little on the under-engineered side to
me. That may just be my ignorance and aversion to callbacks speaking.
At any rate, the details are as follows. First, we sand the raw edges
to eliminate sawmarks. Then, we break the edges heavily (paint
doesn't like to adhere to sharp corners/edges). Then we slather on a
heavy, thorough coating of Bondo. After it cures, we sand the Bondo
smooth. Then we paint. We've used both oil & latex paints, with no
problems so far (the newest is about 3 years in service). It's
important to prime the surfaces well. We use either the primer that
matches the topcoat, or a good fresh 2 pound cut TINTED shellac.
After the first, light primer coat, we sand very carefully. After a
second coat of primer, we sand lightly. Then we follow with 3-5 coats
of topcoat.
Depending upon the aesthetics, I might be tempted to fiberglass tape
& epoxy treat the edges - if I were doing it for myself. Based upon
our experience to-date, it's likely overkill.
Hope that's helpful.

Hi Bryant,
At Arbor Woodworks, we have done several similar projects. We have
treated the raw edges w/Bondo (polyester based automotive filler
compound) before painting. The specification - received from the
architects involved - seem a little on the under-engineered side to
me. That may just be my ignorance and aversion to callbacks speaking.
At any rate, the details are as follows. First, we sand the raw edges
to eliminate sawmarks. Then, we break the edges heavily (paint
doesn't like to adhere to sharp corners/edges). Then we slather on a
heavy, thorough coating of Bondo. After it cures, we sand the Bondo
smooth. Then we paint. We've used both oil & latex paints, with no
problems so far (the newest is about 3 years in service). It's
important to prime the surfaces well. We use either the primer that
matches the topcoat, or a good fresh 2 pound cut TINTED shellac.
After the first, light primer coat, we sand very carefully. After a
second coat of primer, we sand lightly. Then we follow with 3-5 coats
of topcoat.
Depending upon the aesthetics, I might be tempted to fiberglass tape
& epoxy treat the edges - if I were doing it for myself. Based upon
our experience to-date, it's likely overkill.
Hope that's helpful.

"Moderation in all things, especially moderation"
This is about MDO, Crezon to be specific - but it's a bit OT.
One of my Honey-dos is to prep a 4'x4' piece of Crezon for - of all
things - a highway sign. I figure whatever anyone would do for above
waterline treatment would work well here. What would you recommend
for sealing edges, priming, painting? And I need to keep this cost
effective (cheap) so I'm not using 2 part epoxy paint!
