I am a brandy NEW to all this wonderful creative stuff so don't take this as what I recommend.

Cost wise - I need to be aware of what I am doing.  I am not a professional and I don't sell stuff - YET!!

I am experimenting with exterior grade stuff and I have recently designed and made an anchor for a Tattoo Studio.

Based on the awesome teachings of Sandy Baird in Indiana, I used Extira - which is an exterior grade MDF. 

It is VERY heavy and cuts easily enough.  I don't know yet, how well it holds up in the weather.

I am learning

Hey Leo,

Jamie - I have a story to go with it.  It is in process and much needs to be done.  It is just primed but I'll grab a pic later.

I do have some questions that you can help me with.  This may not be the correct place for the question, but here goes.  You can move it to a more appropriate place.

I need to make a 5 point star.  I did the star, and the points are ok, but the between points surfaces are curved, not so good.

I used the star draw feature in Aspire - then made component in the modeling tab - middle feature to make it prismatic.

I know - not real descriptive.  I will try to get a preview later.

Post a preview so I can see. I have found that making a star turns out better if you split each arm off, make it a component, then multiply the component into the star pattern, using the merge feature.

I kinda tried some variation of that but got some funky results.  I am in and out of the shop working - then cooling off.  I will post what I am doing later tonight.

Leo,

I live in New Hampshire very close to the Mass. border.  I placed an unpainted piece of extira outside more than 2 years ago.  It is exposed to "everything" including the city snow plow.  After 2+ years, it is just starting to split into "layers".  If it is properly primed and painted, it should last for many, many years. 

I have read that the best way to prime it is to scrub it with soap, water, and scrub brush.  Then apply a good quality primer.  I have tried this method with good results.

Extira dust is very bad for you.  I think it is due to the urethane binder.  Use a good quality respirator to protect your lungs.

Paul Thank you.  That is great news.  Unfortunaly, I will not get to "test" the Extira before selling it.

I will be making yard decorations that I will be able to watch.

Where in New Hampshire are you?

Leo,

I've used extira for exterior trim. It's been outside exposed to the elements for 2 years and looks the same as it was installed. You have to seal all cuts (anything cut or carved. I used 3/4" and 1 1/4" material. They were trim rings for column bases.

I used one coat of a mixture of titebond exterior glue mixed 1/2 and 1/2 with water. Brush it on, lightly sand, then paint as usual. No soak-in, paint covers really well.

We use a lot of Extira, It's a great material for certain applications. We did a water bucket test, where we placed a piece in a water bucket. I think it took a couple of months before it started expanding.
We had a "quickie" sign out in the elements for 4 years, digital print applied to the face of it, unprimed, unpainted, back and all edges exposed and it was in great condition when I finally got around to fixing it.
