2. Laying the Floor Tiles
Reminder - you need to watch the instructional videos to get a full understanding of the process, please don't
rely on these written instructions alone. Don't feel like you need to watch them all at once - just watch the
section that you're about to do before you do it, so that it's fresh in your mind.
2A - LAY FRONT CENTER TILE OF FIRST LAYER
Lay the front-center tile, making sure it's level with
your stand so that the other tiles can be laid flush and
level with it.
2B - CONTINUE LAYING FIRST LAYER
Lay the remaining tiles for the first layer, working from
the front to the back. The first layer of tiles are marked
with chalk to help you identify them. As these tiles are
for the sub-floor heat bank they will likely have some
chipped corners and edges. These are being covered,
so this does not pose any issue - and helps us to keep
the cost of the oven kit down by using tile bricks that
would otherwise have to be cut into other shapes.
2C - LAY FRONT CENTER TILE OF SECOND LAYER
Lay the front-center tile, making sure it's level with
your stand so that the other tiles can be laid flush and
level with it. You will likely need to wet down the first
layer of tiles to do this; a light spray with a hose or a
wet sponge.
2D - CONTINUE LAYING SECOND LAYER
Continue the process and bed each tile down into the
Hybrid Bedding Mortar mixture, ensuring that each
is level and the edges are flush with each other (as
close as you can). Make sure the tile marked 'C' is
placed in the center, as this is where your trammel
tool will pivot from. Keep the joints between the tiles
as tight as possible, remembering that gaps of up to
2mm are normal and once they're all laid, you can fill
in the joints with the same mortar mix if you want (it's
