Purchasing stone tiles there are many different points to consider.
When purchasing stone tiles there are many different points to consider. The first would be the size of the tile. Stone tiles come in a large multitude of sizes and this is one of the first things you should consider, what are the ideal sizes for your area and do you require just one size of stone tile or several in order to create a pattern. Also consider the depth of the stone tiles you are looking to purchase. The depths of stone tiles commonly vary between 10mm and 20mm and normally the larger the size, the thicker the depth.
When considering the type of material to use, as well as thinking about the kind of look you are aiming to achieve it is important to consider the practicalities in regards to the environment the stone tiles are being used in. Do you require a hard wearing tile, a tile which can withstand frost and do you require a tile which can be cut easily enough for awkward laying areas.
Another important aspect to consider is the finish of the material. There are two common finishes for stone tiles, polished and natural. A polished effect gives the tile a high-gloss reflective finish and this is common in marble and granite stone tiles. A natural finish gives the tile a matt, non-glossy finish, this is common in limestone tiles and also makes the tiles less slippery under foot compared to polished material. Most stone tiles have a honed finish which is a term used to describe how the face of stone is ground down to the same level, where as some stone tiles (often slates and sandstone) can have a riven finish which is where the surface is left with its natural riven texture. The edges of natural stone tiles can be sharp or softened, again this varies with the material.
When dealing with a natural stone vendor, it is important to ensure that the stone tiles you purchase all come from the same quarried batch, if they are all to be laid in the same area. It also a good idea to check the companies back ground and history in order to avoid dealing with a business which may not supply with you with consistently high quality material.
