Why are some stones so expensive?

+

Stone prices vary largely, and this is mostly to do with the location and size of the stone quarries. Remote or smaller quarries mean that they are harder to get to and harder to quarry which leads to a scarcity of product and surge in pricing. Other factors could be the mineral content in the stone and the cost of logistics in bringing the product to you.

Why is granite the most used stone type in kitchens?

+

Kitchen and bar counters are commonly exposed to liquids like water, milk, juices, wine or other alcohol, acidic substances like citrus vegetables, some fruits, acetic acid as well as sharp utensils, all of which can damage any countertop. However, Granite is one of the strongest and most dense stones in nature with high tolerance to heat and tension due to which it is resistant to etching, staining and absorption making it one of the top choices for use in kitchens and bars.

Tile

What are porcelain tiles?

+

Porcelain tiles are made up of 50% feldspar and are fired at a much higher temperatures than regular ceramic tiles. This makes porcelain tile harder and denser than other tile products. Because of its highly durable make-up, porcelain tile is more resistant to scratches and can withstand temperature extremes. Also, because porcelain is non-porous, it is very stain resistant, has very low water absorption ratings (Less than 0.5%) and can be used for interior and exterior applications as well as heavy-use and commercial areas.

What are through body tiles?

+

Unglazed porcelain tiles are a solid color all the way through the tile body and do not have a top glaze. These tiles are generally referred to as through body or full body tiles. They are typically denser and more durable than glazed tiles and also have good slip resistance. However, they do need to be sealed to avoid staining. These tiles are especially good for high traffic areas due to their ability to withstand wear and tear.

What grout size should I use for my porcelain tile?

+

Grout joints are an aesthetic preference. The general trend has been to use thin grout joints that are 1/8” to 3/16” with a 1/4” joint being the optimal size for a layout with multiple tile sizes. An important factor to remember when deciding grout joint size is that the bigger joints attract more dirt and tend to crack versus thin joints.

What is nominal size in tile?

+

Tile is usually referred to by its nominal size, not its actual size. During the firing process, ceramic tile will shrink, on average, by about 10% in size. For example, a 12” by 12” floor tile will actually measure 11-7/8 inches square. Currently, the most popular ceramic floor tile are the larger sized tiles such as 13” by 13”, 16” by 16”, 18” by 18” and 36” by 36” sizes.

What is rectified tile?

+

Rectified tiles have all the edges mechanically finished to achieve a more precise facial dimension. Rectified tiles can have smaller grout joints thus needing lesser amounts of grout and can be more aesthetically pleasing.
