When it comes to installing tile on cement board, it is important to consider which side of the board should face out. The two sides of the cement board have different textures – one is smooth and the other is rough. The decision of which side to face out depends on the type of adhesive you will be using for the installation.
If you plan to use thin-set mortar adhesive, it is recommended to face the rough side of the cement board out. The rough texture of the board provides better adhesion for the mortar. The rough surface allows the mortar to grip onto the board, creating a strong bond between the tile and the cement board. This is particularly important for larger and heavier tiles that require a secure installation. Using the rough side out also helps to minimize the risk of the tiles slipping or shifting during the installation process.
On the other hand, if you will be using latex mastic adhesive, it is recommended to face the smooth side of the cement board out. Latex mastic is a type of tile adhesive that is premixed and ready to use. It has a smoother consistency compared to thin-set mortar. The smooth side of the cement board provides a better surface for the mastic to adhere to. The smooth surface allows for even distribution of the adhesive, ensuring a proper bond between the tile and the cement board.
It is important to note that following the manufacturer’s instructions for the specific adhesive you are using is crucial. Different adhesives may have their own recommendations for the orientation of the cement board. Always refer to the adhesive manufacturer’s instructions for the best results.
In my personal experience, I have used both thin-set mortar and latex mastic for tile installations on cement board. I found that following the recommendations for which side to face out based on the adhesive type helped to ensure a successful and long-lasting installation. The rough side provided a better grip for the thin-set mortar, while the smooth side allowed for a smoother application of the latex mastic.
To summarize, when installing tile on cement board, face the rough side out if using thin-set mortar adhesive and the smooth side out if using latex mastic adhesive. Following the adhesive manufacturer’s instructions is crucial for a proper and durable installation.
