Installing The Proper Substrate
Once the surface is prepared, the next step is to secure the area you are tiling.  Nothing is more important
than your prep work.  There are many options for underlayments and it can get quite confusing if you aren't a
professional.  Each tile project has special circumstances to consider when choosing one.   
Strength and
solidity
are very important to ensure that your product will endure many years.  Waterproofing your tile
sub-floor is extremely necessary in applications such as shower floors and walls.  Getting a smooth
finishing
height
can be challenging in order to create a nice transition from floor to floor.  Always consult a professional
before installing your own sub-floor.  The main types of substrate are:  3/4" dry pack with wire lath and tar
paper, 1/2" cement or fiber board, 1/2" green treated sheet rock, 1/2" sheet rock, 1/2" Denshield, 3/8"
self-leveling cement1/4" cement or fiberboard, 1/4' Denshield, 1/8" Ditra, 1/16" anti-fracture membrane,
shower pans, and concrete slab.
In Floor Heat
Heated floors
are an
option to consider
before started your
floor tile project.  
Since heat rises
floors are the
coldest part of the
room.  With in-floor
heat it now
becomes the
warmest.   The

set of cables in
which a thin layer of
cement is poured
over them prior to
tile installation.
