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.
You should do three sponging cycles in order to maintain the cleanliness and stunning of the tile. The purpose of the first sponging is to clean the excess grout over the tile second is to smoothed the joints and third is to clean any residue left on the tile. However you have to allow minutes of time between sponging cycles because this allow the grout to set properly. Also be reminded that use the clean side of the sponge when wiping and cleaning the tile after grouting. And lastly wipe down the tile the next day to help seal the grout and to clean the tile as well. Always make sure that you use the correct sealant labeled for natural stone tile in order to maintain the appearance of the natural stone tile. Many people complain about natural stone floor tiles absorbing dirt or start developing holes after few years.
Laying your natural stone tiles is a relatively simple process involving the use of tile adhesive to fix the tiles to the surface. Some types of particularly porous tile such as travertine require back-buttering with tile adhesive before theyre laid. This is also important if your tiles have any cracks in the underside since buttering will help to seal the crack and add strength and the process is considered good practise in any situation. Take care when laying natural stone tiles as they can be quite heavy. Take care to minimise unnecessary stretching to reduce the risk of back-strain. You can use a spirit level to help check your tile is level before moving onto the next one and a gentle tap from a small mallet can help to encourage any corners that are too high. Grouting your natural stone tiles after theyve been laid is again a fairly simple process. Do use a mask when mixing your tile grout as it can be a considerably dusty process. Always mix your grout powder with clean cold water and if youre laying your tiles in a bathroom or kitchen you wish to use a tile grout that features anti-bacterial agents to reduce the growth of mould and mildew.
