Installing tile on gypsum board requires specific adhesive types to ensure proper adhesion and protect the substrate.
You can install tile on gypsum board by using appropriate adhesives like ready-to-use paste adhesive or a high-performance polymer-modified adhesive specifically designed for tiling onto gypsum board, applied with a notched trowel.
Choosing the Right Adhesive
Selecting the correct adhesive is crucial when tiling directly onto gypsum board (drywall). Gypsum board is sensitive to moisture, so the adhesive choice helps mitigate this risk and provides a secure bond.
Based on recommended practices for tiling on this substrate:
- Paste Adhesive: Paste adhesive should be used, because of its ready-to-use property. This type is often convenient for smaller projects or areas with low moisture exposure.
- High-Performance Polymer Adhesive: A high performance adhesive with polymer composition, which is designed for tiling onto gypsum board, is highly recommended. These adhesives offer enhanced bond strength and flexibility.
Application Method
Proper application ensures the adhesive performs correctly and minimizes potential issues.
When using the recommended high-performance polymer adhesive:
- Prepare the Gypsum Board: Ensure the surface is clean, dry, and free from dust or debris. Any damage should be repaired.
- Apply Adhesive: The adhesive should be applied using a notched trowel. This is essential in order to control the amount of adhesive and also to prevent the water seeping into substrate layer. The notches create ridges that collapse when the tile is set, providing even coverage and reducing air pockets.
- Set the Tiles: Press the tiles firmly into the adhesive with a slight twisting motion to ensure good contact.
- Grout: Once the adhesive has cured according to the manufacturer's instructions, grout the tile joints.
Using a notched trowel with a high-performance adhesive helps manage the moisture content applied to the gypsum board and ensures a strong, uniform bond for the tiles.
