Water and oil repellent

Besides crystallization, there is another option to protect the floor from stains by using a water and oil repellent product. There are several products whose efficiency and durability vary according to the type of stone and the applied treatment.

These products improve resistance to stains but can not provide 100% protection against stains. These products are impregnated in the stone and have the advantage of a natural look without any protective layer on the surface of the stone.
In spite of the fact that they are less environmentally friendly, solvents are still the most effective. The floor must be completely dry before applying the product. This can take several days.

The advantage of the impregnated water and oil repellent protection is that it can be applied to almost any type of floor and finish (honed and crystallized).
