Precautions For PVC Floor Construction In Winter


1. Transportation and loading and unloading of plastic floor

In winter, the temperature is low, and the material is hard. Don't use it brutally.

2. Storage of plastic floor

Materials must be stored indoors, kept upright, and take safety precautions.

3. The influence of temperature on the construction of PVC plastic floor

The temperature at the construction site of PVC plastic floor shall be above 15°C. When the temperature is lower than 10°C, the installation of elastic floor is prohibited.

4. Environmental temperature and humidity requirements for resilient floor construction

Air temperature: ≥18°C, air relative humidity: 40-70%, surface temperature: ≥15°C, base water content: fine stone concrete (≤3. 5%), cement mortar (≤ s2%), heating floor Ping (≤1.8%), flatness: 2M less than or equal to 2mm, base layer bonding tensile strength: ≤1.0Mpa.

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

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

Self-leveling: Too low temperature will cause the self-leveling drying time to be too long or even be frozen, unable to complete hydration and timely drying, and it will be dried in the later stage, and the surface will have no strength, and there will be quality problems such as surface sanding or cracking. In a warming environment, pay attention to the relative humidity of the indoor air. Too dry will directly affect the self-leveling cement's moisture volatilization too quickly, failing to complete the hydration process, and causing the self-leveling to lose strength.

Special glue for floor: The best construction temperature of glue should be above 15°C (18°C is the best). If the indoor temperature is below 10°C, the bonding strength of the glue will be greatly affected, which will cause the floor and the ground The bonding is not strong, and problems such as degumming and edge warping appear in the later stage. Strictly control the drying time of the glue during construction.
