What is the SPC flooring

In the world of floating floors, laminate flooring (also known as laminated wood) has been a popular alternative when we are looking for resistant, economical, easy-to-install flooring.
But this alternative has a detail that not many overlooks, its water resistance, because, technically, it doesn’t have it. This requires special care when the laminate flooring comes into contact with any liquid and should be dried the affected area immediately.
For this reason, the market has offered other types of floating flooring which can offer better water resistance. Among them are plastic flooring, especially vinyl, which has been present as an ideal alternative to improve its resistance to accidental liquid spills.
One that stands out is the LVT (Luxury Vinyl Tile), which shares the advantages of the floating flooring, keeping up the ease installation.

Although this LVT flooring seems to be the ideal solution when moisture-resistant flooring is required, there are certain characteristics that are not necessarily the most sought after by the market. Among these characteristics, its susceptibility to telegraphing can be highlighted. This refers to the tendency to show the imperfections of the mortar (or surface on which it is installed), that is, any defect that the surface has will be evident, as can be seen in the following photo.

To avoid this behavior, the mortar level must be flattened before the flooring installation, in such a way that these defects are corrected. This leveling procedure increases the cost of labor and the final cost of the project.
Another type of unwanted telegraphing on the LVT surface is that produced by pressure of heavy furniture or pointed heels.
All this is due to the low thickness of the LVT floor and its 100% vinyl (PVC) composition, which is soft by nature.

The vinyl flooring industry was looking for a way to provide rigidity and structural stability to its flooring, which they got by mixing polyvinyl chloride (PVC) with a mineral called calcium carbonate (CaCO3), from this mixture the SPC floor was born (Stone Plastic Composite) a floor composed of plastic and minerals.
The SPC flooring, which is also known as “rigid core flooring”, has a central structure composed of 70% calcium carbonate and 30% vinyl, providing rigidity and structural stability far superior to traditional LVT, but without leaving a aside the realistic appearance and the practicality of a floating flooring.
Its advantages include improved dimensional stability, high wear resistance, thermal and acoustic insulation, rigidity and 100% water resistance.

This water resistance is shared with all vinyl floorings, since its polymers are excellent insulators.

This attribute cannot be understood as impermeability, since they are different concepts. Impermeability refers to the property that certain surfaces have to reject water without letting it pass through it. In the case of the SPC and the LVT floorings, we are referring to floating floorings, that is, boards that do not adhere to the surface on which they are installed, they only rest on it. There is no glue, and the joining between the boards is done through a mechanical system known as “click system”. All this allows any liquid to pass freely between the boards, depositing the water below them. This accumulation generates permanent contact with water and humidity, which produces a proliferation of mold, fungus and dirt that, in the medium term, deteriorate any material, including vinyl floorings.

All the vinyl floorings, although they are 100% water resistant, are not waterproof. This kind of flooring resist any accidental and occasional spill, but must be completely dried to prevent contact with liquids or moisture, and thus prevent it from prolonging the water exposure and end up deteriorating the material.
