What should be paid attention to in the winter plastic floor construction?

1.Transportation and loading and unloading of plastic flooring: The temperature is low in winter and the material is hard, so do not operate it roughly.

2.The storage materials of plastic flooring must be stored indoors, kept vertically, and take safety precautions.

3.The influence of temperature on the construction of PVC plastic floor The temperature of the PVC plastic floor construction site is required to be above 15°C. When the temperature is below 10°C, the installation of an elastic floor is prohibited.

4.Environmental temperature and humidity requirements for elastic floor construction Air temperature: ≥18°C, relative humidity: 40-70%, surface temperature: ≥15°C, base moisture content: fine stone concrete (≤3.5%), cement mortar (≤s2%) heating floor (≤1.8%), flatness: 2M less than or equal to 2mm, base bonding tensile strength: ≤1.0Mpa.

5.The influence of temperature on the construction of auxiliary materials

Interface agent: The essence of the interface agent is emulsion. When the temperature is 5-8°C, the interface agent cannot form a film. After being applied on the base floor, it will become a layer of powder. It cannot play the role of penetration and bottom sealing, resulting in the inability of the self-leveling to be firmly connected to the base floor, and hollowing and cracking will occur later.

Self-leveling: Too low temperature will cause the self-leveling to dry for too long or even freeze, and it will not be able to complete hydration and timely drying. In the later stage, it will be dry, and the surface will have no strength, and quality problems such as surface grinding and cracking will occur. In a warming environment, pay attention to the relative humidity of the indoor air. Too dry will directly affect the rapid evaporation of the self-leveling cement water, and the hydration process cannot be completed, resulting in the loss of strength of the self-leveling. Special glue for flooring: The best construction temperature of the glue should be above 15°C (18°C or above is best). If the indoor temperature is below 10°C, the bonding strength of the glue will be greatly affected, resulting in the weak bonding between the floor and the ground, and problems such as debonding and warping will occur later. Strictly control the drying time of the glue during construction.
