Many time we receive calls about hard water spots. I thought it might be good to show you just what hard water damage on stone or ceramic tile looks like.
This example is a porcelain tile that looks like a Emperador marble. This tile is affected by hard water. In the before photo on the left notice the white build up of minerals by the floor drain. This is exactly what hard what will do. It forms a stone like material of minerals that is very hard to remove. On natural stone it can be a bit worse. The minerals deposits can leach the calcium out of the stone causing it to break down and crack. Some times the surface of the stone looks like it burst.
Repairing mineral deposits is time consuming but can be done. The process is similar to what a dentist does when he cleans your teeth. On natural stone many times after removing the deposits the surface of the stone will need repair as well.
Iv been asked if we can test for hard water and this time we can’t. We do get regular calls about hard water problems in a shower. However most of the time it is not the problem.
