bluue or pink foam

[Anonymous]

We built a via duct using white foam (5 laminated layers glued together) covered with concrete, has held up for around 4 years now - just need to patch up when a tree branch falls on the via duct.

Hi jmozz
Some people have used the white packing foam for buildings
that are ouiside.
I questioned the use of that type of foam. apparently with the proper finish its fine.
However you will need to build your buildings on a slate or similar base
so they dont blow away.
regards John.

Jmozz, according to the article there are two types, gatorplast, and gatorfoam.

The author suggest using the gatorfoam only for outside structures.

Let us all know of your results.

I've found that there isn't any noticeable difference in the blue and pink foam that I find in my area. I am on the cheap side so I check out any work site I see in the area and ask for their scrap pieces of foam. A couple of times there would be almost whole sheets thrown away.
I have been trying different ways to make stone work using foam and am trying to finish a page now on what I have been doing.
I will post a notice when I have it finished.
Here are a couple of ways to use foam.

Jmozz, haven't seen you around in awhile! Good to here from Ya!

The pink foam is more ridged then the blue and generally comes in thicker sheet around 1 1/2 inches where as the blue is commonlly found in 3/4 of an inch thickness. both will work well providing you use a foam board adhesive, many construction adhesives will eat right throught it.

I did see an article on gator board in I belive model railroader but can't rember if you can use it outside. I'll check my back issues and report back.
