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.
Using the edge of a trowel generously fill in the gaps between your tiles (created by using spacers) and smooth it over the surface at a 45 degree angle to the floor. A grout profiling tool can help after youve applied the grout to smooth the fill off and remove any unwanted excess. Caring for your natural stone tiles it an important to remember and before you finish your tiling job you need to seal the tiles to prevent the stone from becoming stained. This seal needs to be applied after tiles have been cleaned and any residual dust adhesive or grout has been removed with a residual remover. After applying and removing the residual remover a seal can then be added to help prevent materials and liquids from entering the pores of the stone and leaving potential marks. This seal needs to be regularly maintained in order to keep the tiles in good condition and can even be added to through the use of enhancing products to bring out the natural grain and contrasts of the stone.
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.
