MDO Cut out signs

Post by Roderick Treece » Mon Mar 07, 2011 11:16 am

I am getting ready to do a 3' x 15' flat cut out shaped sign and of course my first thought is to use 3/4" MDO. I like it because I know I can glue up the sheets ,fill the seem and paint it to look like a seemless background.
My issue is that I had a major delamination failure of MDO a few years back so I am a little gun shy on using it again.
My question are
#1 , What does everyone else prime with, seal the edges with and top coat with ?
#2 What else could I be use instead ?

Thanks

Who are you? What you got in your poke?

After all the problems I've heard about with MDO, I haven't had any.
I still like MDO for many apps. The best primer around, and I've tried many,
is Benjamin Moore's Fresh Start, the green label can, it is a water base primer.
It sands very nicely, if you choose to do so, after three days it dries as hard as a rock.
In our nice California weather, it can dry within an hour or two, allowing you to prime coat two or three times
in the same day, and it can be top coated with any medium. I will use nothing else.

PVC is a excellent material as well, if you like fabricating with it.
I have a Dead Man friend nearby with one of them fancy compu-routers,
Marshal Lee, he does a great job for me. and, the Fresh Start primer is
an excellent media for PVC as well.

That'll be a hundred dollars, hundred dollars for advice.
and he took that golden hair and made a sweater for baby bear.

Roderick,
Give us an idea what exactly you are fabricating. I can't quite picture what
you might be putting together.

Roderick, .........like Tonysaid , Bill Blumberg and I have been using Fresh Start waterbased primer for a long time and have found it the best. As far as materials, I choose not to use much wood anymore ...used it for a long time, I love wood, but it's too labor intensive. For most of my painted/dimensional work, I go with a Dibond substrate bonded to an aluminum tube frame with Lord acrylic adhesive 406/19 as the base on which to build.

Roderic,

Titebond III is very good for sealing the edges......just use your finger.....it dries very fast and sand. (Don't forget to round the edges.)

I'm a Ben Moore Primer fan too......they have a new one....100% acrylic..."Superior Primer". They say it has better sanding qualities. Recoat in 3 hrs.
