Pesticides in my floor

GBA Editor | Posted in Green Building Techniques on

I have a 23000 sq. ft. ranch built on a slab with in-floor radiant heat and an all-tile floor. The problem is that the mortar (thinset) used has an antifungicide in it, and due to my chemical allergies it has been causing many allergies issues for me.

Besides tearing up all the tiles, are there other solutions that will seal in the antifungicide? For the stuff becomes a vapor and is much activated when it hot and particularly humid.

    You may have to check with an industrial hygienist or your local public health department. But I suspect that you'll have to completely remove the offending grout.
