Basics of filling spaces between tiles: techniques and instructions for the optimal composition.

Filling the spaces between tiles is an important part of tile installation to ensure its sustainability and beauty. Here are some basics, techniques, and guidelines for achieving the optimal combination:
1. **Choose the appropriate materials**:
- **Mortar (Hash)**: It is used for relatively large spaces. It can be cement mortar or non-shrinkable mortar.
- **Grout**: Suitable for narrow spaces and comes in multiple colors to match the tiles.
2. **Surface Preparation**: Ensure that the surfaces between tiles are clean, dry and free of dust or impurities.
3. **Preparing the material**:
- Follow the manufacturer's instructions carefully for mixing ratios (if you are using mortar or dry grout).
- Mix the material well until you obtain a homogeneous consistency.
4. **Application of the material**:
- Use a grout spoon or tiling spatula to distribute the material into the gaps between the tiles.
- Gently press the material to ensure that all spaces are filled well.
5. **Remove excess**:
- After filling the gaps, use a damp sponge to clean the excess from the surface without removing the material from the gaps.
6. **Drying**:
- Allow the material to dry completely according to the manufacturer's instructions before using the area. This may take from several hours to 24 hours or more.
7. **Final cleaning**:
- After the material dries completely, gently clean the surface to remove any traces of grout or mortar.
8. **Maintenance**:
- Make sure to check gaps regularly and refill any voids that may appear over time.
By following these steps, you can achieve a clean, durable tile installation that combines aesthetics with durability.
