Gypsum based underlayment or more properly gypsum based substrate present many advantages, but also
a few challenges to the tile installer. CaSO4 calcium sulfate is the component of gypsum based underlayment
and when in contact with water could lead to the formation of ettringite (hydrate calcium aluminium
sulfate), which could cause an increase in volume. Gypsum based underlayment needs to be waterproofed
if any exposure to water or moisture throughout the life of the installation is possible. Please follow

PRODESO HEAT SYSTEM is the ideal solution to install ceramic and
natural stone tiles on gypsum based underlayment.
PRODESO HEAT MEMBRANE uncoupling membrane is laid directly
over the entire surface intended for tile installation, the heating cable
is then installed in the areas where heat is desired using the channels
formed between the rounded square reliefs. It’s NOT necessary to
use self-leveling cement based to cover/ protect the wire before
starting tile installation. This results in saving material/weight/time/
cost. Tile installation can start immediately after installing the heated
cable.
