Actually adding a scratch coat is far superior in that it gives you a rougher surface area to capture more adhesion then just applying the stone directly to the brick fireplace. One area in the video they did make a mistake on! You are supposed to spray the back side of stone with water. This will prevent the stone from drying out the thin set, this robs the curing process! It also assists in making a better bond to the stone to the thin set.
@My Name at least he had something to contribute other than a smartass remark. I’ve been in construction for forty years, and Former Marine is exactly right. Now run along and get a job. Or something.
Hi, I have a 60's thin brick fireplace straight up to the ceiling. Some people say coat the brick, others don't - you didn't in this video. I will be using a slate veneer product - real stone in 6x24 inch pieces which I am assuming are held together with some sort of lathe. So coat the brick or no?
Hi Deborah, I'm not sure I understand what you mean by coat the brick. The fireplace facelifts we do are typically over full bed depth brick (2.5-3 inches deep). Full brick fireplaces typically provide a good solid support structure to adhere stone to. You indicated you had a "thin brick fireplace" What we don't know is how well the thin brick is adhered to the substrate and what the substrate is? The tile is heavy and the thin brick application may not be suitable to support the weight of the stone veneer. Sorry, I am at a loss for advice not knowing more about your 60's fireplace.
Little Peter Oasis hi, sorry to take so long for my reply. I have noticed that some people put a skim coat of cement or mortar, scratch it - let it dry and then install the stone. My fireplace brick is very narrow, with a minor joint - all the brick looks new even though it was installed in the 1960's. I am inclined to not add a skim coat, but I don't want the slate to fall off! thanks
@@deborahsimone6946 Hi Deborah, I am in the same situation as you were. What did you end up doing? Did you coat the bricks with thin-set or installed it directly over the bricks?
@@mohammadbeig no lathe, just heavy weight mortar for the dark gray slate. Came out great - used black granite for the hearth and painted the brick with black grill paint. Used an H burner for gas and covered with turquoise fire glass. Wish I could attach a picture.
