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.
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.
Always take care to wear hand and eye protection as well as suitable clothing and remove and power sockets or electrical equipment that is likely to get wet in the process. When marking a cut line on a natural stone tile you may prefer to use a crayon as opposed to a pencil which is likely to not make a significant mark on the tile. Take care to go extra slow when reaching the end of your cut as if you go too fast and force the tile through it is likely to break rendering it difficult to use. If you are cutting a particularly large tile try to get someone to help you steady the tile as you cut since the weight of either piece of tile can start to pull the whole piece apart - encouraging a snap - as you advance through the tile.
