Bricklaying 101: How To Build A Brick Wall – DIY At Bunnings


Here in front of me is all the tools that
are required for brick laying. You can see I’ve got my trowel, my hammer, my levels.
I’ve got a shovel, I’ve got my trusty wheelbarrow, vinyl [SP], cement and sand. So what we have
to do first is set up our profiles. We’ve got our measurement on the wall. A builder
supplied me with that measurement there, was 1650 back up the wall. Now I’m using today
just a bit of 9035 pine, and generally for brick laying we use 45 x 45 steel but these
are fine. Make sure they’re straight and if they’re straight then they’re right to use
because that’s what our brickwork’s going to run off. So what we need to is do as we stand that
up, we need to have a packer sit behind the profile, so that we can get our string lining
behind. And make sure that our line is visible further back here and then we’re just going
to clamp this to the wall. So I can see my line there, so now all I have to do is plum
down. Now, it is very important to make sure that the bubble is sitting dead center of
the two lines. So that’s bang in the middle so I’m happy with that. Okay now what we’re going to do is we’re going
to mark the gauge on this profile, which is not really that important because we’ve got
existing brickwork, but for the sake of the exercise I’ll show you what to do. So, set
the level, to get the level up the brickwork just simply mark underneath the level. Then
we’re going to take our gauge rod, which I’ve already marked off the existing brickwork.
Now what we’re going to do is we’re just going to hold that on that top level mark there
and then we’re going to transfer the rest of these. So it’s the height of the brickwork.
So we’ve got our profile set up. We’ll duck our line in behind the profile. And what we
have to do for starters is we have to set up a level line. So what I’m going to do is
I’m going to set this with five courses above, one, two, three, four, five. And then I’m
going to go over to our other wall here which is also completed. And I’ll need to count
down five from the top, so one, two, three, four, five. So the line needs to be nice and
taught. And if there is a sag in the line then your brickwork is not going to be level. I’ve got my line set up. So what I need to
do to check that this concrete’s level or close enough to level, is I’ll put my gauge
right here and I can see on my gauge rod that I need to get up probably 20, 25 mil, which
is not a big deal, I’ll be able to do that easily enough. So what I’m going to do is
I’m going to lay this first brick with a larger bed than I’d normally lay. I’m just going
to pop him down there. I’m just using my eye for now for sight, but then I’ll sit my gauge
right on top and that tells me that I’ve probably got half of it there, which I’m pretty happy
with. So I’m just going to get half to start with and then probably get the second half
in the next course. So what I need to do now is just grab my level
and I’ve just got to plum down to make sure that’s in the right spot. That’s essentially
where I want to have it, so what I’m going to do now is I’m just going to block this
one down. Just put a bit of mud on the back of the brick. Just creates and angle so that
the brick will sit forward and it will hold the line down for me. And you’ve got to be
very gentle when you do this, because you can actually knock the brick and then you’ll
lose where you’re at. Now I’m right to lay this first course. This
bed is a lot bigger than it would normally be, so I’m going to need a little bit of extra
mud on the bottom. So you take up this much mud for buttering a brick and then just flick
it back onto the trowel ’til it settles, and then it stays onto the trowel nicely. Just
a good strike and push down, like you’re buttering a piece of bread essentially. So push that
down, you want about that much on there. And what that’s going to do is enable us to get
the front and the back and it’ll have something to adhere to. So there you go, she’s ready
to go. So this comes up. We’ll take him away. And
then what we’ll need to do is just fill that in, continue on with our bond. So what we’re
going to be left with here will be a three quarter, so the little notch there. Now what
I want to do is make sure I’ve got my glasses on because chips can fly up and cause some
problems if it hits you in the eye. So nice and gentle as you’re hitting it. Cracks [inaudible
00:04:09] and there you go. Now because I’ve had to lift up the line on those last two
bricks I’ll just check from my level just on top, which it should be pretty good and
it is. Just checking through the front as well, that’s no worries. So now that we’ve laid our first course we
need to go back to where we were before, so that we our level line again. So we’re coming
back up to here. So we’ve got one, two, three, four, five again. We’ll go back to our other
end and do the same, so we’re sitting here. One, two, three, four, five, level line. So
now that I’m laying this next dummy brick, I can actually lay this so that it’s going
to be in bond when I set it in. So, what I want to do is make sure that that pair up
underneath is sitting in the middle of this brick, which it just about is right now. Now
I’m just using my eye to eye down the faces, and I will check that but I’ll do that first,
I’ll check, so we’re getting very close now. So this isn’t essential to do this in two
courses or in three courses, because we’ve got another five above the line, we’ve got
six above this. So if we grab two mil each course we’ll have it by the top. So you don’t
want to have a big messy bit at the bottom and then go from there. Okay, so it’s safe
to go down again now. And as you can see with the spreading here of the mortar I’m just
laying it down. I’m just picking up some excess stuff from the sides, so you get a nice little
triangle shape. Then you just go straight through the middle and just feather through
it. So you get that nice pattern and what that does is it creates that air pocket in
there, so that it’s nice and easy to lay a brick on it. That’s why it’s called a bed,
because that’s the comfort that the brick gets when it sits down on top. So there you go. So that’s got us out of the
ground. We’re now able to use our gauge at that end, which is right. We’re able to use
our already established brickwork at this end. So we’re right to finish off our wall.
Five courses to go and we’re done. More often than not we lay half on brickwork, so it’s
one brick sitting on two bricks. So all the way through it’ll be sitting half on. Okay
last brick going in now, just as important as the first one. There we go, all done.
