MVIS Best Practices Part 4: Masonry Installation Method for Thin Brick and Natural Stone


Okay I just showed you the trowel method
for the thin brick now I’m going to show you the masonry way for adhere veneer
and natural stone. But first I want to make sure that you
understand that the old mason way is not the way of doing it now. So when you have a piece of stone and you’re not using Type S mortar anymore, instead of
buttering the backs like you would with Type S mortar, creating the ring for
suction. We’ve all seen this done on many jobs. This can be an issue. One, it allows
for air pockets to happen where you can have freeze / thaw effects. The other is
you’re not getting consistent coverage across the back and you’re not getting
good transfer to the wall and the stone at the same time. When these are being
set you always gave it kind of the wiggle and jiggle and then you had to
hold it in place. With the new mortars you don’t have to do that. If you’re
doing the freehand you mix it to the consistency that you need and then
you’re going to start setting your veneer stone. We already had these clean
and proper. What I want you to do differently, is take the stone and you’re
going to put some mortar on the back. You’re going to give it a quick scrape.
Instead of back buttering it like you did it on the old one you’re just going
to give it a quick scrape and then you’re going to put some of the mortar
to a even consistency on the back. Okay. Almost the same way but I want it to be
solid all the way across. Then you’re going to take the piece of stone, you’re
going to place it into the wall give it a nice firm pressure, give it a nice
slide and then back into place and let go. Alright. Once you get to that point,
any of this excess mud you can take off. And that’s the reason for the square
notch trowel on the back. So any of this mud just take it off. That’s money that
you’re saving down the road. Okay, once you get that set then you can
go to your next piece. Same process just a quick skim is all you need. That
ensures that you’re getting good transfer to the back of the stone and
then butter it up you get the coverage that you’re requiring. Then you’re gonna take your next piece of stone, press it into place.
I always start right next to the piece of stone that is already set, press it, give
it the slide and then back into place and let go. It’s that simple.
Take any of that excess, put it in the bucket. Anywhere we can get it. Then we
can take our other piece. Set it the same way. Nice line and then
back into place. And we’ll do our last piece to kind of give
you the idea of how it works. Quick skim that’s all it takes. And butter it up. I
just increased my bond strength 2- 3 times versus just putting it onto the
back of this stone. Just want to try to make sure we’re getting good coverage. Start on top of the next piece, give it a
quick slide, back into place. You got a joint or not? You do, I put a
little bit too much mud in there before I collapse it I want to remove that just
to make sure I don’t have a big build up in the joints. All right. Now the other thing you can do
is re-adjust with these products. You have a stone that doesn’t quite like look
right, you can move that and put it back into place
instead of Type S and starting over. Now we’ll look at some of the new products
that are coming out that you have to deal with and install with those. you
