This is a off the wall question (litteraly) I gotta motel that ive done some work for that wants me to put down that clear/protectant floor coating on some stonetile, 63 bathrooms and several larger areas. I understand it takes some prep/cleaning, anybody used this stuff? should it be bid like I bid painting? probably 2 coats? how long before the room can be used? ive never worked with it, but this place really wants me to do all their work, and this is opening a door for me that is very profitable, the place is less than a year old. they just never really finished alotta things, any help?
