Let me give you a clear and interesting answer to the question of whether SPC floor installation must be self-leveling!

SPC Floor + Self-leveling = Better installation results?
First of all, SPC floor due to its locking structure and hard stone plastic composite material, theoretically does not have to be self-leveling. Its requirements for the ground are relatively loose, especially compared with wood floors and tiles, simply "friendly" much more! However, self-leveling can really be the icing on the cake, so that your floor laying effect is better.

So, when do you need to self-level?
In short, if your ground has the following conditions, it is best to level off:

1. Uneven ground: If your ground is uneven, the SPC floor will make a sound because of the unstable foundation, and even affect the service life of the floor.
2. Cracks or potholes: there are large cracks or potholes on the ground, which may affect the locking structure of the floor if directly laid.
3. Too inclined: If the ground is significantly inclined (more than 2-3 mm height difference), it still has to self-leveling to maintain the level of the ground.


When can I not do self-leveling?
- The ground is already flat: If your ground is already flat and can be paved with a little polishing, it can be completely saved by self-leveling.
- Lay on existing floor: For example, you plan to lay SPC floor directly on tile or wood floor, as long as the existing floor is not too much defects, directly lay on it.

The benefits of self-leveling
Self-leveling is equivalent to providing a "perfect stage" for SPC floor to make its performance better:

1. Higher flatness: Self-leveling can ensure that the ground is smooth enough, so that the lock is more tightly splicing, and it is more stable to step on.
2. Reduce noise: The ground is flat, the floor will not produce abnormal noise due to uneven force, and it is more comfortable to walk on it.
3. Extend the service life: The floor is firmly installed and smooth, and the durability is naturally higher.




Sum up
SPC floor installation does not necessarily have to be self-leveling, but if your ground has a significant height difference or uneven surface, self-leveling can make your floor more beautiful and durable. If the ground is in good condition, you can skip this step altogether! But remember, the flatness of the ground is the key to the installation effect of the floor, can be stable, the performance of the SPC floor will be more perfect!

I hope this will make it easier for you to understand!
