I learned here on somebody's post last week that pre-mixed plaster used in building construction has gluten in it. This explains so much of why I have so often gotten weak and sick at work, and the same with my business partner who also has celiac. It can't just be old age since we are otherwise perfectly fit.

It makes me suspect other building materials--like glues for vinyl flooring, wood patch and the like. Can anyone give me a heads up on this?

I am the boss so I can have what I want at the building site. I want it to be gluten free as much as possible for obvious reasons.

Fortunately the plaster is an easy thing to correct since I used to always mix the plaster myself. It dries faster and is harder than the pre-mixed sort. Now I know why. I suppose if I want to extend it I can put cornmeal in it like my Dad did to create texture on the walls.

Any insights here would be a great help!
