SPC stone plastic floor with its waterproof, moisture-proof, wear-resistant and other characteristics, known as the floor of the "iron Man". A lump in the head? This sounds like a superhero suddenly grew a strange "tumor", but in fact, SPC floor under normal use conditions, is not easy to bulge. However, there are exceptions, and let's talk about under what circumstances the floor may encounter this "bulge crisis".

1. Installation problem: Expansion joint is the key!
  The installation of SPC floor needs to leave expansion joints, which are the "breathing mouth" of the floor. If there is not enough expansion space reserved during the laying process, when the floor encounters temperature changes, thermal expansion and contraction can not proceed smoothly, and the floor will be suffocated out of breath, and then bulge. Just like if you wear pants that are too tight, you will feel uncomfortable moving too much, and the floor is the same.

2. Long-term water: waterproof does not mean "bath"
  Although SPC floor waterproof performance is first-class, it does not mean that you can let it soak in water every day. If there is water under the floor for a long time not treated, there will be "water vapor" between the floor and the base, resulting in bulges. This is like you take a waterproof mobile phone to take a bath, although not afraid of water, but who every day in the water will also have problems!

3. Inferior materials: Be careful of the "low matching" floor
  When buying flooring, if you are greedy for a cheap time, you may buy some substandard products. Poor quality SPC floor, the substrate is unstable, in the temperature and humidity changes in the environment more easily bulging, deformation. Therefore, choosing the right manufacturer and the right product is the first step to ensure the long-term stability of the floor. Just like choosing friends, good quality "friends" can last a long time.

4. Uneven base: Lay a floor, not a blanket
  Although the SPC floor has its own "tough halo", it also needs to be supported by a flat base. If the ground is potholed when it is laid, the pressure on the floor is uneven, which may also lead to local drumming. To put it simply, laying the floor is like laying the sheets before going to bed, the flat foundation makes you comfortable, and the floor is the same.

5. Large temperature changes: the floor is also afraid of "changing mood"
  Although the SPC floor is heat-resistant and cold-resistant, if your house temperature is like a "roller coaster", hot and cold, long-term extreme temperature will accelerate the expansion and contraction of the material, which may cause the floor to bulge. Therefore, maintaining the indoor temperature is an important means to keep the floor "calm".

To summarize:
  SPC stone plastic floor itself is very resistant, bulging phenomenon is not common, but you should ensure that the expansion joint is reserved in place when laying, the ground is smooth, and try to avoid long-term water accumulation or dramatic fluctuations in temperature difference. After all, the floor also has a "temper", as long as you treat it well, it will remain bright for a long time, accompanying you and your family through every step. Also don't forget, when installing the floor, don't forget to ask a professional master to help you with these details, small preventive measures, can save the follow-up big trouble!
