Maintenance
Due to its natural characteristics, all marble and granite suffer damage with the usage of and are able to change in their appearance resulting from the usage, contact with the environment, aggression by external agents and the general maintenance. In general, the granite rocks are more compact and hard that the marbles, and their resistance are recommended for intense use of local.
Both the marble and the granite are porous, some to a greater degree, others a lesser degree, depending on their composition and are suitable for internal flooring. However, we must be careful to waterproof the floor, for application in ground floor. It is advisable to use white cement in the most sensitive of light colors to avoid the appearance of changes in their natural color. In this case, avoid the most porous marbles (higher absorption of water) at risk of stain with the humidity, despite the sealing.
Some wear and changes in appearance are inevitable, but a proper maintenance helps to prolong the beauty of natural stone.
The suggestions above do not prevent that the material changes its appearance due to time and use, but it helps to minimize such effects.
