Can anyone tell me if Grout is safe to use. I've seen previous post which suggests it is https://umd.net/forums/construction_substances#postid_417452 but note there is different types. It is floor tile adhesive + Grout. Been missing un-fair tv recently, loved the risk aspect plus liked the gungings as well. Think the Restaurant was staged but sure some aren't.
If it has any type of contact warning with the skin then i would not use it. Also take care with adhesives as they can due a number on your skin when you try to get them off.
