Natural Stone / September 4, 2018 / FifineAsselin
Out of all the natural stone materials Sandstone is the most absorbent; Travertine Limestone and Slate all have a medium absorbency while Granite is pretty much waterproof. It is also known that any polished materials will also absorb less water. The next factor to consider it the quality of the materials which is measured in grade. Grade can refer to the size shape and thickness of the tiles along with the condition of its surface. The most common grading systems use three levels of quality. Grade 1 is the highest quality. Everything is uniform and there are virtually no flaws. Grade 2 refers to any materials that have minor defects such as chips scratches or an irregular surface. Grade 3 materials have noticeable major flaws in size shape surface or chipping which makes them only appropriate as accent pieces or used in rustic decorative pieces. The next thing to think about is the coefficient of friction.
Whenever you have a plan of placing a grout in your natural stone tile you should allow 1-2 days from when you applied the adhesive before beginning to grout. Always make sure that you clean the grout joints thoroughly and have taped off the areas which are not included in grouting in order to avoid grout from spilling over the tile. Mix the grout according to manufacturers specifications. It should have a fine consistency in order to have a fine and lump-free finished product. After you have done pouring all the natural stone tile joints with grout clean the surface of the tile with damp cloth after 10 minutes but be sure not to wipe out the grout from any of the tile joints.
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.
