What is Dryvit?

[myxpykalix]

I saw a bunch of this stuff sitting outside. It was about 2'x4'x4" and was a foam product and not sure if it is suitable for use in anything or what it might be worth?

What you saw was just the EPS board. It probably had the Dryvit Logo on it (or on the clear plastic bags it was wrapped in). EPS is bead board (aka what a cheap foam cooler is made of).

Dryvit is the brand name of an exterior synthetic stucco system for buildings. There basic system consists of the EPS boards you saw covered with a thin mixture of Dryvit Primus (a gooey gluey goop) and portland cement. This mixture is applied to the EPS and then you embed a fibreglass mesh (long blue rolls) into the wet mixture. When that dries you coat it with their 1-part synthetic stucco product that contains the color. Texture is achieved with different trowel and float techniques.

I got a few bundles of that foam in my rafters too. I dunno what the current cost of the foam is but I have applied acres of Dryvit, R-Wall, Sto, Pleko, Finestone (all essentially the same thing) before the market went to pot.

Pretty nutty fact... when Dryvit was first introduced we charged more for applying Dryvit than building brick walls.
