Answer: With the best warranty money can buy and ease of use KERDI !
Why It Is Used:
You install tile
backer (also known as backer board) under tile in wet areas because tile
needs a good, solid base or substrate.
But not just any type of material will work as a
substrate.
Cementitious vs.
Organic:
What about wood or
green board as a base? These materials do not work because you need a
cementitious base--one that has the qualities of cement and masonry, cousins of
tile.
Wood, regular
drywall, and even
green board have organic elements which will degrade in high-moisture
environments.
Troweled On Base vs.
Sheets:
Cementitious tile
base is nothing new. Tile installers for thousands of years have created
a thick base of mortar upon which to lay the tile.
Installing a backer
board is a substitute for troweling on countless thick layers of mortar as a
base. In essence, you are getting your troweled on base--except that all
the work as been done for you in a factory and is delivered to you in a nice,
compact, and hard form: backer board.
Types of Tile Backer
Board
1. HardieBacker
- Manufacturer: James Hardie Industries
- Composition: Unlike pure cement board, the
fiber is almost invisibly integrated into the board, making for cleaner
cuts. HardieBacker comes in both 3' x 5' and 4' x 8' sizes.
But unless you are installing as a team, you will find the large
size too heavy to handle on your own. HardieBacker is 90% Portland
cement and sand, along with patented MoldBlock technology.
- Details: If you expect to apply fiber
cement board in areas of high water volume (tiling a bathtub, for
example), you will want to install a barrier of 4 mm plastic behind the
backer board.
- Review: For DIY tile installers, HardieBacker
reigns supreme. Available at Home Depot, HardieBacker's 1" x
1" grid make measuring easy and cutting a snap (literally).
2. DenShield
- Manufacturer: Georgia-Pacific
- Composition: This glass mat is up to 5%
continuous filament glass fiber along with gypsum--the main ingredient in
drywall.
- Details: DensShield is denser than even
HardiBacker. Glass mat is waterproof, eliminating the need for a plastic
barrier. The DensShield product also claims to be mold
resistant.
- Review: If you are comfortable working with
drywall, this product is for you. DensShield scores and snaps with a
standard utility knife.
3. Wonderboard
- Manufacturer: Custom Building Products
- Composition: Wonderboard is
a very fibrous material, its cement core heavily interlaced with long
fibers designed to help hold the board together.
- Details: Available in 36" x 60" sizes
(either 7/16" or 1/4" thick), Wonderboard can be cut with a
utility knife.
- Review: I find Wonderboard difficult to work
with, as it tends to crumble easily and needs to be treated gingerly.
Screws do not grab very well, tending to pull straight through.
On the good side, Wonderboard is cheaper than HardieBacker, so will
be more cost-effective with large installations.
- It can be quickly cut right
where it is installed with a basic utility knife without crumbling or
disintegrating
- Simply attach with backer board
screws or roofing nails
- GoBoard™ is waterproof
- Seal only the board joints and
fastener locations with urethane sealant for a waterproof tile assembly as
per GoBoard™ installation instructions
- For tile installations –
showers, wall, ceilings and floors
- On concrete floors GoBoard™
will act as a thermal insulation under tile.
- Can improve the efficiency of
radiant heat by up to 40%
- Acts as an uncoupling membrane,
reducing the risk of transfer cracks in tiles.

6.wedi Panels
wedi
Building Panels are so much more than a simple tile backer board and offer
endless installation opportunities. Available in a wide variety of thicknesses
and sizes, they are compatible with virtually any substructure. wedi Building
Panels are lightweight, internally waterproof and dimensionally stable, making
them fast, clean and simple to work with. The blue waterproof core is CFC-free,
made from waterproof extruded polystyrene foam, reinforced with fiberglass mesh
on both sides and coated with synthetic polymer resin mortar which fully embeds
the mesh layer resulting in the panel’s strength and the ability to develop
highest adhesion strength to virtually any type of thinset mortar. The embedded
mesh eliminates the risk of delamination of installation layers.
The
wedi Building Panel combines the benefits of the latest manufacturing
technology and material quality with sound and traditional benefits our trades
enjoy. wedi Building Panels are waterproof, lightweight, easy and clean to cut
and still incredibly strong and bond friendly for use with any type of thinset
mortar application. The wedi Building Panel can be tiled with all types of
ceramic, glass or stone tile whether they are mosaic or large format tiles.
Especially large and thin tile benefits of the durability of the wedi Building
Panel and the even surface it provides.

7.KERDI
BOARD
Schluter®-KERDI-BOARD
is a multifunctional tile substrate and building panel, which can also be used
for creating bonded waterproofing assemblies with tile coverings. It consists
of an extruded polystyrene foam panel, with a special reinforcement material on
both sides and fleece webbing for effective anchoring in thin-set mortar.
With the available
panel thicknesses of 3/16", 3/8", 1/2", 5/8", 3/4",
1", 1-1/2", and 2" (5, 9, 12.5, 15, 19, 25, 38, and 50 mm),
KERDI-BOARD allows the installer to prepare and create a broad range of
substrates and building elements for the installation of ceramic and natural
stone tile that are flat, level, plumb, square, and dimensionally stable. With
suitable preparation of the abutting seams and joint areas, the panel may be
used for bonded waterproofing assemblies.
The boards are simply cut to size with a utility knife. The
gridlines, which are printed on the surface, are helpful for neat and quick
cuts and installation. Tiles can be installed directly over KERDI-BOARD using
the thin-set method.

While having used the majority of the products
on this list, and respecting the educated opinions form the authors of each
snipet which are noted. Kerdi coming out on
top is a no brainer for me as a contractor, the warranty is great, user friendly for sure, all around
Great
product. For the Home Owner or diy’er not so much there is a certain
level of installation
understanding and appropriate steps that must
be followed for a claim to be issued.
