Seal tiles made of natural stone and close pores

Natural stone has porous surfaces that are particularly sensitive to damp and wet soiling. To give them a similar insensitivity as ceramic surfaces, tiles can be sealed. The continuous protective layer covers the stone, but at the same time it loses its characteristic.

Consideration between appearance, effect, care and protection

The attractiveness and appeal of natural stone lies in its authenticity and characteristics. Its special sensitivities, however, sometimes lead to severe and unpleasant pollution. If maintenance is to be reduced, a complete finish of the surface, which resembles a finish, is a practical protective measure.

As an additional price for a transparent seal also a change of the haptic and optics must be paid. Sealed natural stone tiles and tiles is to be regarded as having a kind of lacquer coating on them.

Compromise impregnation

An impregnation does not close the pores, but fills them only partially. This results in a reduction in the sensitivity to moisture and moisture, without turning them off completely. Sealed natural stone corresponds to ceramic tiles.

Advantages and disadvantages of sealing

The pros and cons of a seal are also a bit in the eye and the opinion of the beholder. Some natural stone friends consider it inconsistent to dress a natural product with "foil". Other stone lovers do not want to give up the look and still get easy-care and insensitive wall and floor coverings.
