How to lay bathroom dry paving
In recent years, the dry paving process in bathroom decoration has gradually become a hot topic due to its advantages such as convenient construction and good waterproof performance. This article will combine the hot content on the Internet in the past 10 days to introduce in detail the steps, precautions and FAQs of bathroom dry paving to help you easily complete the bathroom decoration.
1. What is bathroom dry paving?
Bathroom dry paving is a ceramic tile laying process. Different from the traditional wet paving method, the dry paving method uses dry hard cement mortar as the base layer and then lays the ceramic tiles. This method can effectively reduce the phenomenon of hollowing and improve construction efficiency, and is especially suitable for humid environments such as bathrooms.
2. Steps to Dry Bathroom Flooring
| steps | Operation content | Things to note |
|---|---|---|
| 1. Basic treatment | Clean the floor to ensure it is smooth and free of debris | Waterproofing treatment is required and a closed water test is required |
| 2. Mix mortar | Mix cement and sand in a ratio of 1:3, add water until dry and hard | The mortar should not be too wet. It is better to hold it into a ball and spread it when dropped to the ground. |
| 3. Laying mortar | Spread the mortar evenly on the ground to a thickness of about 3-5cm | Use a scraper to smooth the surface, leaving a certain slope for drainage. |
| 4. Laying tiles | Gently tap the tiles into the mortar and check for smoothness with a level | Leave a 2-3mm gap to facilitate later seams. |
| 5. Maintenance | Avoid stepping on them within 24 hours after the installation is completed | Seams can be processed after 3 days |
3. Comparison between dry paving and wet paving
| Comparative item | Dry laying method | wet laying method |
|---|---|---|
| Construction difficulty | lower | higher |
| Hollow rate | low | higher |
| construction speed | Fast | slow |
| Scope of application | Large size tiles | Small size tiles |
| Cost | slightly higher | lower |
4. Frequently Asked Questions
Q: Is the dry laying method suitable for all ceramic tiles?
A: The dry laying method is more suitable for larger-sized ceramic tiles (such as 600×600mm or above), and the wet laying method is recommended for small-sized ceramic tiles.
Q: What is the waterproof performance of dry laying method?
A: The dry paving method itself does not have waterproof function. The base layer must be waterproofed and a 48-hour water closure test must be done.
Q: Will there be hollow drums caused by the dry laying method?
A: As long as the construction is standardized, the hollowing rate of dry paving method is much lower than that of wet paving method. The key is to ensure that the mortar is moderately dry and hard and is fully compacted when laying.
5. Construction Tips
1. Soak the tiles for 2 hours before laying to reduce hollowing caused by water absorption.
2. Use a professional tile leveler to effectively ensure the flatness of the tiles.
3. A 1%-2% slope should be reserved on the bathroom floor to facilitate drainage.
4. It is recommended to choose ceramic tiles with an anti-slip coefficient of R10 or above to ensure safe use.
6. Material usage reference
| Material | Usage (per square meter) |
|---|---|
| cement | 12-15kg |
| medium sand | 0.03m³ |
| Tile glue | 3-5kg (optional) |
Through the above detailed introduction, I believe you have a comprehensive understanding of the bathroom dry paving process. In actual construction, it is recommended to choose the appropriate laying method according to the specific situation, and consult professional construction personnel when necessary. Only standardized construction techniques and high-quality materials can ensure the quality and service life of the bathroom.
