4. Practical tips to prevent floor bulges
Based on the discussion of popular notes on Xiaohongshu, we have summarized the following preventive measures:
1.Humidity control:Keep the indoor humidity between 40% and 60%, use a dehumidifier in the rainy season, and the floor heating temperature in winter should not exceed 28°C.
2.Installation specifications:8-12mm expansion joints should be reserved around the perimeter, and transition strips should be added every 5 meters on the composite floor.
3.Basic processing:The cement leveling layer needs to be cured for more than 28 days, and a moisture-proof film (thickness ≥0.2mm) should be made before laying.
4.Routine maintenance:Avoid soaking in large amounts of water, wring out the mop when cleaning, and add protective pads under heavy objects.
5. Professional maintenance cost reference
According to recent decoration platform quotation data:
| Maintenance items | Unit price range | Warranty period |

| Basic treatment | 30-80 yuan/㎡ | 6 months |
6. Effective tips tested by netizens
1.Ice cube cooling method:A hot search on Weibo shows that applying ice cubes in a sealed bag to the raised area for 2 hours can cause the solid wood floor to shrink.
2.Book flattening method:Zhihu's highly praised answer recommends using heavy books to press evenly for 48 hours, which is effective for laminate floors.
3.Hair dryer adjustment:According to the actual measurement by the UP master at Station B, low-temperature hot air combined with heavy objects can improve the slight deformation of the SPC floor.
In summary, the problem of raised floors requires different measures to be taken depending on the specific situation. You can try to solve minor problems by yourself.
