So we're driving a piece of tile here that we'd cut it's going to be two pieces mirror, essentially they were seen in the middle and we're drive fitting in this and setting this one in place.

So that we know where it's going to go that way we can base our measurement off of for the next one.

Then using a piece of the wall tile it'll be on the face on the side returns here as a gauge because I want to line up my heart pile with my wall tile and give it some allowance for thinset about a sixteenth, because the trial I'm going to use for this little grooves stand about an eighth inch tall.

When you're tipping track at a 45 degree angle, right and they're evenly spaced so that you could smush the tile down within 1/16 or so.

So we have about a sixteenth of an inch thin set for the backside of these.

So I, literally use this as a gauge to line up my heart.

And the reason again, we're dry fitting this piece.

So that we can measure the piece off of it.

You know exactly where it's gonna go before it goes there, hey, guys.

So we're gonna take a measurement for this next piece of tile here on this heart and I have a little spacer here.

So the Horseshoe spacer sixteenth inch and that's, what we're going to use for the scene here to put a sixteenth inch, grout line, essentially it's going to act as the edge of the tile.

So I blood that and that's where the edge of tile is going to be.

And on this end, I have my little gauge title because it's like some of the rhetoric on here and a measure to that and I, added 16 things for thinset and I have 41 and 3/4 would be with my 16th of an inch I'll fix that.

So my fancy dancing a little scratch pad on my tape.

Measure I, draw a picture of the tile living.

The cut okay.

And then I draw the measurement 41 and 3/4 or it's gonna go so I measure my tile out and have a picture that way know exactly how it's going to be cut 78.

And that gives me a little play here because this is gonna get covered with the fireplace insert.

And then if she's covered with the tile.

So this cut doesn't have to be exactly perfect.

You want to have a little bit of play because you tried to get too tight too greedy.

Just you're just gonna have to cut it again.

So I have all the measurements I need to make this cut.

So I'm gonna make a cut now we're recording now light refraction and all that scientific stuff, because in the door last it's, the rainbow it's, amazing, how a horse rainbows, rainbows rainbows speaking of rainbows, all right.

So we have our two pieces of tile for the heart.

Dry fit almost exactly where they're gonna go.

And now I need to install them in order to do that again, make a thin set.

And over here, we've got some pockets plug it with some water in it.

So I can put water to my bucket I'm gonna put that together.

Yeah, here's the bag thing set all right, it's, pretty much like a cement that is made for bonding.

If you use something like liquid nails to glue, two pieces of wood together.

This is the liquid nails, the time.

So I'm gonna put my mask on and I wouldn't suggest this, but somebody who's inexperienced, but I can kind of ask me how much water I think I'm gonna need versus how much Vincent in movies.

We don't like this mix up a whole bag for a couple pieces of silly very nasty for this pile of it.

This is very thin set.

This is what you use the thin set it dumb whips the mud up without creating a whole lot of resistance there's paddle bits that you can use for drywall mud, mixing paint, which is silly I think the next paint with a petal bit.

However, people do it.

This one is made to cut through the mud because it's heavier more dense.

So that way you're not fighting.

It I stayed on the bucket that way with a bucket moving around.

Do you think and sometimes it gets really gnarly all right? So it started Macross this and mixes been set then I can already tell you a lot more okay.

So how much power you have it up it's a fun game of water powder, water powder? Well, so we mix in the thinset you're gonna have these dry clumps common on the side of the bucket take another cloud scrape along then we get those dry buggers and add it to the lever now before we let it slide.

It has a pretty good consistency.

But after a flat, which is the part where it sits for 10 minutes and does whatever it does.

Yeah, just touch more water because I don't want it to step.

It does reason they call it thin set, but not too thin set kind of like peanut butter, almost like, um, like a puddin.

If peanut butter and pudding had a baby.

They would be, you know, thick enough to stand up and keep its shape, but thin enough to work.

Yeah, that right there is perfect.

Because it ten minutes after it, slides it'll, be even a little more stiff and still be thin enough to work with so we're gonna let it slide for 10 minutes looks like pudding like it says, right here on the instructions of this particular brand, you mix it up you.

Let us lock the 5 to 10 minutes, and then you mix it again.

So I'll, see you in 5 to 2 minutes? Ready? Oh, I just got it.

All, oh my leg.

This is cold the great day, well, speed, your roll don't see that I know, some spread pizza here for the large-format tile I'm, using a half inch square notch trial here.

And the purpose of these trials is to evenly spread what we call mud.

So it makes contact with the backside of the file 100% now, 98% way to set the depth could smoosh it down a little.

If we have about 3/8 of an inch of mud here to make contact the tile could go down to about 3/16 before these.

We just show you a little example here before these make contact so I'm touching there.

And I smoosh it down to get the elevation of what I want and go down about half the depth before they make contact with each other.

So depending on the depth, you need for the tile will indicate what size trowel.

You want to use and we're calling it evenly these air gaps, also about just that inter get underneath.

So it can dry now we're gonna lay our piece, and that requires two people.

So now the piece in place, I think I want to make sure we check is that even with the spacers here.

And here given sixteenth inch, spacing, I want to make sure this fraud is nice and straight you're, just trying to line up those two edges, yeah and make sure that they're, nice and straight.

We have our sixteenth inch spacing here.

Another thing you like to check, you can't really tell with the level, something you use the naked eye is that you have this surface plane as well.

And if we can get the camera down a little lower, you might be able to see that this side is actually slightly higher than this side.

So it looks like I can lift it up.

Oh I, see, yeah.

So that they plane, nice and perfect.

So that when the hardwoods just shine aim, the camera down up in the top bird's eye, the hardwoods are but up against this and they'll be a little lower it'll.

Be about a quarter inch.

Lower, yeah, that way we don't have any imperfections.

You're always gonna have something perfection is just a matter of where you put.

So now I'm going to use some shims just a line up this edge.

Here, I'm really, not find a sixteenth income in here that might work needs a little more it's.

Gonna do is I'm gonna take one out since the sixteenth of an inch increment quite work.

Use some wedge spacers, the taper.

So that I can five there.

We go that's a lot better right there.

Yeah, we got it that please fun stuff fun stuff.

And then I'm gonna put some blocks here for safety cuz, uh, when you have to pile on thin set, even though you don't plan on dancing around it or stepping a honey, you want to slowly move because there's, nothing pinning it in place in one of the directions, it's nothing to that right complete the wall in place.

But it can't fly this way.


What you can do is you take a walk double check out a little it's, nice and straight.

We have a wood subfloor to screw to blocks a pin in place.

You know, kidnap here.

Now would wait one day 24 hours 24 hours.

These blocks will stay on until the end.

Yep tomorrow, dance on it.
