When laying SPC floors, whether the tiles below ** need to be removed ** mainly depends on several factors, including the flatness of the ground, height requirements, and individual needs and budgets.

First of all, if the original tile floor is kept flat and not damaged, the cement floor formation performance after the tile removal is enough to meet the laying requirements of the SPC floor, then the SPC floor can be paved directly on the tile floor without removing the tile. This saves time and money, while avoiding the dust and noise pollution that may come with removing the tiles.

Secondly, if the tile floor is uneven, or the cement floor after the removal of the tile needs to be levelled, then in order to ensure the laying effect and stability of the SPC floor, it is recommended to remove the tile and carry out the necessary ground leveling work.

In addition, if the floor height is limited, or you want to lower the floor height to match other renovation requirements, you can also consider removing the tile. However, when removing tiles, care needs to be taken to protect the surrounding walls and furniture to avoid damage.

Finally, whether to remove the tile also needs to be decided according to the individual's needs and budget. If you want to save money and simplify the decoration process, and the original tile floor is in good condition, then you can lay SPC flooring directly on the tile floor. If the pursuit of better laying effect and stability, or the original tile floor condition is not good, then it is recommended to remove the tile and carry out the necessary floor treatment before laying SPC floor.

In short, when deciding whether to remove the tile, it is necessary to consider several factors such as the flatness of the ground, height requirements, personal needs and budget. It is recommended to consult a professional decoration team or floor installer for more specific recommendations and programs.
