This should not be counted as a negative side to natural stone tiles as there are ways to maintain them and we must bear in mind that any natural products requires maintenance. Once natural stone tiles are laid there are three steps that must be done to maintain the tiles which includes filling washing and sealing. This process must be repeated every two to five years depending on the quality of natural stone. The first step after laying the tiles is to fill them. All the holes must be filled with filler of the same color. Any gap between the tiles must be grouted. You need to allow one to two days for the filler and grout to be dried.
The absorption rate is how porous a material is. The more absorbent a material is the more likely it is to stain as well as how much cracking damage it suffers during freezing conditions. There are four different levels of absorption when it comes to natural tiles. Non-vitreous is the highest absorption and should not be used in any environment that can become damp. Semi-vitreous are less absorbent but will require more maintenance the more liquid is exposed to them. Vitreous is the standard level of absorption and is considered most appropriate to be placed in areas with low to mid indoor or outdoor traffic. Impervious is the most resistant when it comes to the absorptions of liquids and are the easiest to maintain and clean.
There are different types of sealer such as invisible sealer color enhancer sealer deep sealer etc. Depending on your purpose you would choose the proper sealer. For example invisible sealer does not change the character or color of your tiles while still protecting it but color enhancer sealer will make your tiles darker and will bring the color out. Deep sealer is used for more porous natural stone such as limestone and sandstone. This process must be repeated every couple of years depending on the type and quality of you Stone. For example for travertine and limestone this should be done every two to three years and for granite and marble it could be done every four to five years.
