Which Side Of Cement Board Does Tile Go On Walls Or Not

Cement board is a popular backer board for tile installations, both on walls and floors. It is made from a mixture of cement, sand, and fiberglass, and is available in a variety of thicknesses and sizes. Cement board is a strong and durable material that is resistant to moisture and rot, making it an ideal choice for use in wet areas such as bathrooms and kitchens.

When installing tile on cement board, it is important to know which side of the board the tile should be applied to. The smooth side of the cement board is the side that the tile will be installed on. The rough side of the cement board is the side that will be attached to the wall.

There are a few reasons why the tile should be installed on the smooth side of the cement board. First, the smooth side of the cement board provides a better bond for the tile. The rough side of the cement board has a more porous surface, which can make it more difficult for the tile to adhere properly.

Second, the smooth side of the cement board is more likely to be flat and even. The rough side of the cement board can have bumps and ridges, which can make it difficult to install the tile evenly. If the tile is not installed evenly, it can create a bumpy or uneven surface that is not aesthetically pleasing.

Finally, the smooth side of the cement board is more resistant to moisture. The rough side of the cement board can absorb moisture, which can lead to the tile becoming loose or falling off. The smooth side of the cement board is less likely to absorb moisture, which makes it a better choice for use in wet areas.

When installing tile on cement board, it is important to follow the manufacturer's instructions. The manufacturer will provide specific instructions on which side of the cement board the tile should be installed on, as well as the type of adhesive that should be used.
