SPC floor, known as "stable as Taishan", but sometimes, it will also come to a little temper, quietly inflated, people confused. Don't worry, let's talk about the reasons behind the "stable big brother" that occasionally make it "unstable".

1. "Thermal expansion and contraction" : The floor is also afraid of hot and cold toss
  Although SPC floors are generally able to withstand temperature changes, they also have to "take a breath" in extreme weather or when the temperature of the underfloor heating system suddenly surges. If the temperature difference in the room is too large, the floor may swell, just like we feel bloated when we wear too many clothes. Therefore, do not create a "sauna" environment for the floor, keep the temperature moderate, it can always sit.

2. "No way out" : no gap left, the floor is too depressing
  When the floor is installed, leave some room for it to "flex its muscles". If there are not enough expansion joints reserved around the floor, there is no place to stretch when the floor is heated, and it will "hold" it to arch upward, like a strong support. The floor also needs some freedom, don't make it too "depressing".

3. "Drinking too much water" : Wet floors are to blame
  Although the SPC floor is waterproof, if the ground below is wet, the floor absorbs water like a thirsty drink of water, and eventually expands out of shape. Therefore, the ground should be dried before installation, and the floor should not be "soaked" in water.

4. "Bumpy life" : The ground is uneven, the floor is tossed
  SPC flooring prefers flat ground and does not want to be "bumped". If the foundation ground is not smooth, the floor is not under uniform pressure, and the local area will be tossed and expanded. If you want the floor to be smooth and smooth, the ground must be smooth and flat, and don't add "bumpy" to it.

5. "Floor dark horse" : Inferior products are also a problem
  Finally, product quality should not be neglected. Some poor quality SPC floor materials are not good, when the temperature or humidity changes, the expansion problem is particularly obvious. Therefore, choose a reliable brand of floor, in order to make the floor at home stable.

Bonus tip:
  What if it expands? If the expansion is not serious, you can try to reduce the room temperature, or partially remove the floor to repair the expansion joint. If the swelling is too obvious, call a professional to help solve it.

To summarize:
  The expansion problem of SPC floor is usually related to temperature, humidity, installation problems and product quality. As long as you pay attention to these factors, your floor will be stable as a rock, accompany you to live steadily, and no longer "expand"!
