Can SPC Stone Crystal Flooring be installed without glue or nails?

Yes, SPC (Stone Plastic Composite) stone crystal flooring can be installed without glue or nails. It typically uses a click-lock installation system, which allows the planks to interlock securely without the need for adhesive or nails. This makes the installation process quicker and cleaner. The planks are designed with a tongue-and-groove system that clicks into place, and the flooring stays in position through its weight and the tight interlocking mechanism.

However, in some cases, a floating floor installation might be used, where the planks are laid on top of a cushioned underlayment, which adds comfort and sound absorption while ensuring the flooring stays in place.

It's important to follow the manufacturer's installation instructions to ensure the best results.
