To get tile to stick securely to a wall, the most common and effective method for most wall tiles is using a specific type of adhesive.
The Primary Adhesive for Wall Tiles: Thin-Set
According to tile installation practices, most wall tiles are best installed with a mortar-based glue known as thin-set adhesive. This material forms a strong, durable bond suitable for the vertical application of tiles.
What is Thin-Set Adhesive?
Thin-set is not just a simple glue; it's a specialized mortar. Its composition is key to its effectiveness:
- Cement: Provides the primary bonding agent.
- Fine Sand: Adds body and strength to the mixture.
- Water-Retaining Agent (e.g., Cellulose): Helps the mixture retain moisture, allowing proper hydration and curing of the cement for optimal strength.
Furthermore, thin-set designed for tile often includes additives that enhance its performance. A critical additive mentioned is a latex additive.
Why is Thin-Set Ideal for Walls?
The inclusion of a latex additive in thin-set is particularly beneficial for wall tile applications. This additive provides:
- Flexibility: It imparts some flexibility to the hardened adhesive. This flexibility is crucial in preventing the tiled surface from cracking, which can occur due to minor structural movements or temperature changes.
- Improved Adhesion: Latex enhances the bonding capabilities of the thin-set, ensuring the tiles remain firmly attached to the vertical surface over time.
Using the correct type of thin-set, specifically formulated for wall applications and potentially including beneficial additives like latex, is the standard practice for achieving a lasting and secure tile installation on walls.
