Kerdi-board is a type of tile backer board that is used in showers and wet areas. It is made of an extruded polystyrene foam core that is covered on both sides with a reinforced fiberglass mat. Kerdi-board is waterproof, mold resistant, and easy to work with. However, it is also very expensive. Some homeowners have had problems with Kerdi-board, finding that it is not as durable as they had hoped. Cracks and chips can occur, and the fiberglass matting can delaminate from the foam core.
We are sorry to hear that you are having problems with your Kerdi-Board. Please contact our customer service department so we can help resolve the issue. Thank you for using our products.

Can KERDI-BOARD be installed directly on studs?
The KERDI-BOARD can be applied directly to gypsum or masonry walls and wood stud framing, as well as over existing finished wall surfaces. It is ideal for creating bathtub and shower surrounds. The 1/2″ thick (125 mm) KERDI-BOARD panels are easy to handle and can be cut to size with a utility knife.
The Schlüter-KERDI is built to last for many years. With proper maintenance, it can last for upwards of fifty years. The materials used in the product are key to its longevity.
Should I use KERDI-BOARD
Kerdi is a great material for installing shower walls because it is lightweight and easy to cut and install. It is also pricier than regular sheetrock, but so much easier to deal with.
We are facing a raw material shortage for our Kerdi-Board production as a result of COVID. We are currently unable to source the materials required for this production. We apologize for any inconvenience this may cause.
How often do you screw KERDI-BOARD?
To install KERDI-BOARD on your framing, start by pressing a washer into the board every 12 inches up the stud location. Then, drill a single screw through the washer/KERDI-BOARD and into the stud. Repeat this process until the entire board is installed on the framing.
Modified thin-set mortar is not recommended to set ceramic and stone tile, including large format tiles, over the KERDI membrane. Modified thin-set mortars must dry for the polymers to coalesce and form a hard film in order to gain strength. If the mortar is not given enough time to dry, it will not reach its full potential and may not provide a strong bond between the tile and the membrane.
What can I use instead of a KERDI-BOARD?
If you’re looking for a cheaper alternative to Schluter Kerdi, check out Profoil. It’s applied the same as Kerdi, but with both in and out corners available.
If you’re working with the Wedi materials, it’s best to be careful with your cuts and to avoid making any mistakes. With the Schluter system, however, you can use the Kerdi band, mortar, offcuts and Kerdi fix to make corrections if needed. This makes it a bit more forgiving, and can help you avoid any problems down the line.
Is Schluter system better than cement board
If you’re looking for a reliable tile substrate that won’t warp or expand when exposed to moisture, Schluter Ditra is a great option. While it is more expensive than cement board, it is more durable and resistant to water damage.
For most installations of KERDI-BOARD, tile can be installed right away. Exceptions include curved wall areas and non-bearing partition wall systems. In these applications, the tiles can be installed once the bonding materials have cured sufficiently to stabilize the KERDI-BOARD assembly.
What is the best backer board for a shower?
Cement board is a good, reliable backer board that works well on both floors and walls. It is important to keep in mind that most tile setters err on the side of caution and brush a waterproofing membrane on top of cement board when it is in wet areas like showers or tub surrounds. This helps to protect the cement board and prolong its lifespan.
Installing KERDI over your drywall panels is a great way to protect them from water and vapor damage. This will help keep your walls looking great and extend their life.
Why can’t you use modified thinset with KERDI
If you’re using Kerdi, it’s best to stick with unmodified thinset mortars. They don’t need to dry out to gain strength, so you won’t run into any issues with the membrane inhibiting drying.
Section “Waterproofing” on the use of KERDI-BOARD in bonded waterproofing assemblies. Minimum board thickness = 1/2″ (125 mm) for studs spaced at 16″ (406 cm) oc; 3/4″ (19 mm) for studs spaced at 24″ (610 cm) oc.
Can you walk on KERDI-BOARD?
The Schlüter®- KERDI-BOARD should not be used in floor assemblies that will experience high amounts of foot traffic as the floor coverings may have a hollow sound when they are walked upon with hard shoes or tapped with a hard object. If you are looking for a product to use in a high foot traffic area, we recommend looking into one of our other products that is better suited for that environment.
Schluter SET, ALL-SET, FAST-SET or an unmodified thin-set mortar must be used to construct all KERDI seams to ensure watertight performance of the system.
How do you secure a KERDI-BOARD
Kirti fix is a thin set mortar that is used to seal the kerdi-board to the shower pan. This will ensure that the board is properly sealed and will not leak.
If you are installing KERDI, there is no need to tape the joints between drywall panels. However, if you are required to do so by fire code, make sure to apply a latex primer over the taped joints before installing KERDI. This will ensure that the KERDI adheres properly and creates a watertight seal.
Is Kerdi board load bearing
KERDI-BOARD is the perfect substrate for tile applications because it is easily customizable, waterproof, and load-bearing. This makes it ideal for use in wet areas like bathrooms and kitchens, as well as for applications where there is a lot of weight or traffic, like entryways and balconies.
There is no back or front to the KERDI membrane, which means that you can install it either way. One side of the membrane has gridlines, which can be helpful when cutting the membrane to size. Keep in mind that you can install the membrane grid side out for convenience in tile setting.
Warp Up
Kerdi-board is a waterproof panel made of gypsum and reinforced with fiberglass that is used to create a tile surface. It is used in showers, bathtubs, and other wet areas. The most common problem with Kerdi-board is that the panels are not always level, which can cause problems with the tiles. Other problems include the panels not being properly sealed, which can lead to leaks, and the panels cracking.
Kerdi-board problems can be a pain to deal with, but with a little patience and the right tools, they can be fixed. With a little bit of knowledge, anyone can fix a kerdi-board problem.
