Sticking tile on a wall primarily involves using a mortar-based glue called thin-set adhesive.
Understanding Thin-Set Adhesive
Thin-set adhesive is the most common method for adhering tiles to walls. It's a specialized mortar typically composed of:
- Cement
- Fine sand
- A water-retaining agent, such as cellulose
- Latex additive (often included for flexibility)
This composition provides a strong, durable bond while accommodating slight movements in the wall and tile, which helps prevent cracking.
Step-by-Step Tile Installation
While a detailed guide is beyond the scope of this concise answer, the core process generally involves:
- Surface Preparation: Ensure the wall is clean, dry, and level.
- Mixing Thin-Set: Prepare the thin-set according to the manufacturer’s instructions.
- Applying Thin-Set: Use a notched trowel to apply an even layer of thin-set adhesive to the wall.
- Placing Tiles: Press tiles firmly into the thin-set, using spacers for consistent gaps.
- Allowing to Cure: Let the thin-set dry completely before applying grout.
- Grouting: Apply grout between the tiles and clean off any excess.
Why Thin-Set is Preferred
| Advantage | Description |
|---|---|
| Strong Bond | Creates a durable and lasting bond between the tile and wall surface. |
| Flexibility | The added latex helps prevent cracking from minor wall movement. |
| Moisture Resistance | Thin-set is more resistant to moisture than other adhesives, making it suitable for bathrooms and kitchens. |
Important Considerations
- Always refer to the manufacturer's instructions for both the thin-set and the tile being used.
- Use the correct notched trowel size as this helps to ensure the proper depth of adhesive.
- Work in small areas to prevent the thin-set from drying out before the tiles are set.
