Ceramic tiles
There are many types of ceramic tile for many different uses. Tiles that are
coloured all the way through are usually dry pressed and fired to sintering tem-
perature. All ceramic tiles can be
glazed.
Floor and wall tiles laid in
mortar
The mortar is made of a mixture of
cement and sand, in proportions of 1:4
or 1:5, and water, giving it the consis-
tency of damp earth. It is laid to a thick-
ness of 2.5-3 cm and evened out. A thin
cement and sand grout (1:1) is then
poured on and spread with a trowel. The
maximum size of the grains of sand is
2 mm. The tiles are knocked in with a
rubber hammer. The joints are then filled
with a cement and sand grout (1:1-3),
the maximum size of grain being 1 mm.
