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.
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.
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.
Let us get into the details about the three points to be considered during the purchase: Solidity: This is pretty an easy thing to measure and people can judge the solidity of the product by breaking it. If it is hard to break the buyer can be satisfied that he has the right natural stone in his hand. Also he can try to drop a hammer from a good height for testing whether it breaks. In some showrooms there will be a separate space for conducting this type of tests on the stones. The dealers provide this sort of space just because of the fact that they are highly confident about the quality of the product that they deal with. If it is of the best quality there will not even be a mark of the hammer.
