How to lay SPC flooring
1. As long as you make sure that the floor is flat, you can connect the "spc flooring" through a snap connection. No glue or nails are needed, and there is no need to worry about destroying the original polished quartz tiles. The coefficient of expansion is very low.
2. "spc flooring" can be connected almost seamlessly due to its extremely low coefficient of expansion, and is not afraid of water overturning and flowing to the lower floor.
3. Use silicone to close the seam with the wall, so there is no need to worry about the expansion joints being too large and unsightly.
