How well do the mats protect the floor?
Yes, they protect the floor well and do not leak. Of course, if you pour a large amount of liquid per 1 square meter, then there may be light humidity on the back of it. Due to the composition of two layers-polyamide, viscose, cotton - the mats absorb moisture well and protect the floor. As a result, with standard use, you do not leave traces and dirt, and your work does not cause any inconvenience to anyone.
