Yes, you need to use thinset mortar under backerboard in order to ensure the substrate is securely and properly adhered. Thinset mortar is a type of pre-mixed Portland cement-based material that is used to adhere cement or ceramic tile to the substrate base.
This mortar is designed to provide superior strength, superior bond, and superior water-resistance to any tile installation. By using thinset mortar under backerboard, it will help to secure it and create an even plane to install the tile.
The best thing to remember when applying thinset mortar underneath your backerboard is to always use a smooth, consistent layer. This will help to ensure that the tiles are even and level and that they adhere correctly to the substrate.
In addition, it is important to note that if water leaks occur between the backerboard and the substrate, then the thinset mortar will act as a waterproof barrier. This will protect the tile and the substrate from damage due to water or moisture.
Overall, thinset mortar is an essential part of a successful tile or backerboard installation. By using thinset mortar underneath your backerboard, you will ensure that the substrate is securely and properly adhered, leading to a long-lasting and beautiful installation.

Can you lay cement board without Thinset?
No, it is not recommended to lay cement board without Thinset. Thinset acts as an adhesive and helps to secure the cement board in place. Cement board needs a strong, durable bond in order to properly and effectively protect surfaces such as walls, floors and countertops.
Without Thinset, the cement board may not be able to achieve the necessary level of durability and could cause the cement board to shift or become damaged over time. Additionally, because cement board is heavier than other backer boards, it is important for the Thinset to be used properly in order to make sure that the cement board is adequately supported.
Therefore, it is recommended to use Thinset when laying cement board.
Is it necessary to use Thinset under Hardibacker?
Yes, it is necessary to use thinset under Hardibacker. Hardibacker is a cement-based, high-density fiberboard panel that is used as a substrate for tiles and other flooring materials. Because it is rigid and non-porous, it provides a strong, stable base for tile installations, but because it does not contain any inherent adhesive qualities, it needs to be securely bonded to the floor with an appropriate thinset mortar.
This mortar is especially important for applications where the substrate may be exposed to moisture—like showers and bathroom floors—as it helps to create a waterproof seal and protect against water damage.
Thinset mortar is generally mixed with water and applied in a thin layer to the back of the Hardibacker and onto the substrate, where it will thoroughly cure and securely adhere the Hardibacker in place.
On a dry substrate, thinset mortar should be used to ensure a long-lasting, waterproof and durable bond between Hardibacker and the substrate.
Can you just screw down backer board?
No, you cannot simply screw down a backer board. You must use a thin-set mortar and other fastening techniques to ensure the backer board is properly secured to the subfloor/substrate. Additionally, you must use the appropriate screws or fasteners for the type of backer board being installed.
The exact installation requirements vary depending on the type of backer board being used. For example, some backer board products such as cement board require the use of corrosion-resistant screws, while other backer board products may require the use of mortar, saucers, or clips.
Additionally, you should always check with the manufacturer for product-specific installation instructions for the backer board you plan to use.
What do you put behind Hardie board?
When installing Hardie board, a water-resistant barrier should be installed behind it to help protect your home from moisture. This could include felt paper, an asphalt-saturated material, or a self-adhering waterproof membrane.
It’s important that the barrier be properly sealed along all the seams, windows, doors, and corners with caulk or flashing to help prevent water from seeping through. Any penetrations, such as outlets or pipes, should also be flashed with a galvanized metal or plastic material to stop water infiltration.
As the water-resistant barrier is placed, a recommended step is to use a rolling pin to press the barrier firmly against the wall to ensure a good seal. Additionally, a vapor barrier should also be placed between the studs and the water-resistant surface to further stop moisture from entering the wall.
It’s also advised to fasten the Hardie board to the wall studs at 12-inch intervals with corrosion-resistant screws to keep the board securely in place.
What kind of thinset goes under Hardie board?
When installing Hardie board, it is vital to use a quality thinset to ensure a lasting bond. The specific type of thinset you should use depends upon the type of subfloor you are using. For concrete subfloors, a premixed latex-based thinset works best, while for wooden subfloors, a waterproof polymer-modified thinset is best.
Combination thinsets also exist that work for both concrete and wood subfloors. Regardless of the thinset you choose, make sure it meets the American Society for Testing and Materials’ standards for use with Hardie board.
Additionally, you should always use a dry primer/bonding agent before applying the thinset, to ensure proper adhesion of the thinset and Hardie board.
Can tile be laid without spacers?
Yes, it is possible to lay tile without using spacers. This is often done when laying small tiles, as spacers may not be necessary to keep the tiles aligned. When laying the tiles, you should use a level to make sure that the surface is flat and that the tiles are placed evenly.
Instead of using spacers, you should leave a slight gap between the tiles, typically 1/16-1/8 of an inch, that can then be filled in with grout. Without spacers, you may need to use a slightly smaller amount of adhesive so that it does not ooze out and cause a bump between the tiles.
Additionally, it is recommended that you use adhesive or mortar that is specifically designed for use with ceramic or porcelain tiles.
Can you stick tiles down with no nails?
Yes, you can stick tiles down with no nails. These glues are normally water-resistant and can withstand extreme temperatures. You may also find some glues that provide a bonding solution to uneven surfaces.
Again, these should be able to attach the tiles firmly and resist heat, moisture and other environmental factors. Additionally, you may use a specialty foam adhesive to secure tiles to surfaces. This option is often used when applying various types of mosaic tiles.
Once the glue or foam adhesive is applied, the tiles should remain firmly in place.
What do you stick backer board down with?
When it comes to sticking backer board down, cement board adhesive or mortar can be used. Both of these materials not only help secure the board in place, but also allow for water and air resistance.
It is important to carefully follow the instructions for whichever type of glue or mortar you choose to use.
When using adhesive, spread it evenly with a notched trowel and press the backer board firmly against the surface. Hold it in place for a few moments until the adhesive sets up. If mortar is chosen, mix it to its desired consistency according to the instructions.
Spread some of the mortar on the subfloor and press the backer board into it. Make sure to align the tongue and groove of the boards and keep them together. Use a level to keep the board from warping.
When finished, allow the cement to dry for 24 hours before continuing.
It is also important to keep in mind that backer boards are constructed using cement and sand, so they are heavier than other wall surfaces. As a result, it is important to make sure the backer board is securely attached to the floor or wall.
By following the instructions above and using an appropriate cement board adhesive or mortar, the backer board will be firmly held in place and ready for tiling.
Is a vapor barrier necessary behind cement board?
Yes, a vapor barrier is necessary behind cement board. Cement board is a form of drywall that is used for tile installations and other wet area projects. It is a great material for areas that need protection from moisture, however, in order to maximize moisture protection, a vapor barrier should always be installed behind it.
The vapor barrier should be a minimum of 6 mil thick and should be installed with zero-perm membranes to provide waterproofing protection. Additionally, all seams should be sealed or taped with a polyethylene tape.
When properly installed, the vapor barrier will add an extra layer of protection against moisture and water vapor, ensuring that cement board is able to perform its primary function of moisture protection.
Is backer board sufficient with only seams waterproof?
No, backer board is not sufficient with only seams waterproof. Seams are important, and should be sealed properly to ensure that the water stays on one side of the board, but it is not enough to keep the board watertight.
In addition to using waterproofing sealant along the seams, backer boards should also be treated with a waterproofing membrane applied to the entire board, whether it is installed on the wall or the floor.
This will block the passage of water, and should be done around sinks, tubs, or other water fixtures. Once the membrane has been applied, the seams should be sealed again. This will provide an effective and proven barrier that will keep moisture out and protect the integrity of the backer board.
What happens if cement board is not waterproof?
If cement board is not waterproof, the cement board can become damaged over time due to moisture and water intrusion. This can cause the board to crack and crumble, which can lead to structural damage to the surrounding walls and flooring.
Additionally, if it is not adequately waterproof, water and moisture can make its way into the interior of the structure, causing mold and mildew. This can lead to a host of health problems for the occupants of the building, and can also create additional damage to the surrounding structure.
To ensure that cement board is properly waterproofed and able to withstand moisture and water intrusion, it is important to use a waterproof coating such as a sealant or waterproof mortar. Additionally, it is important to ensure that all adjacent surfaces such as walls, floors and ceilings are properly sealed to prevent water and moisture from seeping into the interior of the structure.
