**Title:** Creating a Subfloor Step-by-Step
**Summary:**
* Introduction to making a subfloor for laying ceramic tiles
* **Step 1: Explanation & Preparation**
+ Purpose of a subfloor: aligning the rough floor for a smooth finish
+ Tools and materials needed
* **Step 2: Mixing the Subfloor Dough**
+ Ratio: 3 parts sand to 1 part cement
+ Mixing process with water to achieve the right consistency
* **Step 3: Applying the Dough to the Floor**
+ Leveling the floor
+ Applying a thin layer (2 cm) of the dough to the entire floor
* **Step 4: Smoothing and Drying**
+ Using a brush and trowel to smooth out the dough
+ Allowing the subfloor to dry completely
* **Step 5: Final Check and Preparation for Tiling**
+ Filling any holes or gaps
+ Straightening the subfloor with a wooden trowel
* **Conclusion:**
+ The subfloor is now ready for ceramic tile installation (to be covered in a future video)

Here are the key facts extracted from the text, numbered and in short sentences:
**Preparation and Materials**
1. The video tutorial is about creating a subfloor step by step.
2. The subfloor is used to align the rough floor of a house.
3. The subfloor is necessary for laying ceramic or porcelain tiles.
4. Materials used include sand, cement, water, a level hose, a hoe, a shovel, a wheelbarrow, and a brush.
**Subfloor Creation Process**
5. The process starts with leveling the floor using a level hose.
6. A mixture of 3 parts sand to 1 part cement is used to create the subfloor dough.
7. Water is added to the mixture in a well, and it's stirred until a uniform gray tone is achieved.
8. The dough is loaded into a wheelbarrow and applied to the floor in a thin layer (about 2 cm).
9. Tools are rinsed with water before working with the dough.
**Application and Smoothing**
10. A brush is used to apply the dough to the floor.
11. A ceramic tile is used as a reference to ensure the subfloor is level.
12. The subfloor is filled and smoothed using a ruler and a wooden trowel.
13. The subfloor is dampened and smoothed with circular movements using a trowel.
**Completion and Next Steps**
14. The subfloor needs to dry completely before proceeding.
15. Once dry, the subfloor is ready to receive ceramic tiles.
16. A future video will cover the installation of ceramic tiles step by step.
