As a key component of the educational space, the quality of the facade construction directly impacts the utilisation of experience and aesthetics. PVC flooring has emerged as the optimal choice for the facade of the staircase classroom due to its wear-resistant, non-slip, easy-to-clean properties, etc. However, it is essential to strictly adhere to the requirements and standards of the facade before construction to ensure that the flooring is installed correctly. Before the floor is constructed, it is crucial to strictly control the requirements and standards of the facade to ensure the stability and aesthetics of the floor after paving.In this article, we will introduce the PVC flooring pavement stepped classroom facade, the requirements of the ground, facade standards and ground treatment methods.

Ground Requirements：

Firstly, the ground requirements flatness: the ground must be perfectly flat, with no obvious unevenness. Uneven elevation will lead to floor paving after the drum, warping and other problems, affecting the beauty and service life.Dryness: the ground must be completely dry, with no wetness. Damp ground will lead to glue failure, floor bonding is not strong, and even cause mould.Cleanliness: The floor should be thoroughly cleaned and free of impurities such as oil, dust and sand.A clean floor helps the glue to bond the floor better and avoids problems such as bubbles and peeling of the floor.

Hardness and stability: the ground should have a certain degree of hardness and stability, able to withstand the weight of the floor and the wear and tear of daily use.For soft or easily deformable ground, reinforcement is necessary.

Facade Standards：

Secondly, there are façade standards to consider.Verticality: the elevation of the ladder classroom should maintain good verticality to ensure that the floor can be neatly laid without tilting or twisting.Angle consistency: the angle between the ladder facade should be consistent, so that the floor can be a smooth transition, to avoid gaps in the joints or uneven phenomenon.Safety: The floor of the façade should have good non-slip performance to ensure that teachers and students can walk safely when going up and down the stairs, and the edges of the floor should be finished smoothly to avoid scratches.Aesthetics: the colour and texture of the floor should be coordinated with the overall decoration style of the staircase classroom to create a comfortable and aesthetically pleasing learning environment.

Ground Treatment Methods：

Thirdly, the ground processing methodIf the floor of the façade is uneven, the following treatment is required:Sanding treatment: For slight unevenness, a sanding machine or sandpaper can be used to sand, so that the ground meets the level requirements.Levelling treatment: For more serious unevenness, cement mortar or self-levelling material can be used for levelling treatment.The specific steps are as follows:

Ensure the ground is clean and free of dust, oil and other impurities.

Select the appropriate cement mortar or self-levelling material according to the ground conditions, adhering to the instructions for mixing.

Apply the levelling layer by using a scraper or roller to apply the blended material evenly on the ground to ensure a consistent thickness.

Wait for the levelling layer to fully cure according to the material instructions.

Sanding: After the curing process, utilise a sanding machine or sandpaper to sand the levelling layer, ensuring it achieves the desired level of flatness and smoothness.Reinforcement treatment: In the case of soft or easily deformed ground, reinforcement treatment is necessary to enhance the hardness and stability of the ground. You can use wood, steel and other materials for reinforcement to ensure the ground can withstand the weight of the floor and the wear and tear of daily use.

In summary, when installing PVC flooring in a step classroom façade, it is crucial to adhere to the ground's requirements, façade standards and ground treatment methods. Ensuring the ground is flat, dry, clean and stable, the elevation is vertical, the angle is consistent, safe and aesthetically pleasing, and the ground treatment is carried out in accordance with the correct method is paramount to ensuring the quality of the flooring and its long-term durability. During construction, it is essential to adhere strictly to the outlined requirements to ensure each step meets the necessary standard, thereby creating a high-quality, comfortable step classroom environment.
