Water absorption of stone

Question

Is stone with low water absorption a sign of good quality?

Chris · Answer

Not necessarily, there are many types of stone, some hard and some soft,eg sandstone, limestone soft compared to granite, slate etc which are hard.
Soft stone can be treated to resist water absorption but allowing the stone to breath.
Water resisting products such as Thompsons water seal are readily available.

Tony · Answer

No it’s an indication of how dense or how soft the stone is.

Richard · Answer

The quality of any particular stone doesn't depend on the level of water absorbtion, you'll find black granite has a low water and oil absorbtion level compared to a light coloured granite like ivory fantasy that has a higher level of water and oil absorbtion, the quality of a stone depends on the quarry it was mined from and  the people and company who quarry the stone for distribution and their quality control, all stone is pourus and lighter colours tend to be more pourus and need more maintenance and sealing than say a black granite which is considerably less pourus and more condensed, so high quality stone should be sourced from a reputable supplier

Ricki · Answer

It's not dependent on quality. All stones have different densities so it's down to your requirements regarding drainage and discoloration after time and absorbsion.

Chris · Answer

Just means its hard and dense . Unlike sand stone which is soft . Nothing to do with the quantity

John · Answer

NO JUST THE DENSITY OF THE STONE USUALLY HARD ATONE OR GRANITE.
