Problems with Marble in Shower – Two Questions

Question 1.

We put an Italian green veined off-white marble in our steam shower. The pieces on the wall are 6” x 6” and the pieces on the floor are 1” x 1”. The marble is off-white in color and has green veins running through it.

Some wall marble tiles and some floor marble tiles appear to be corroding or disintegrating with normal use. Holes and crevices are appearing in the marble. In addition, when the shower marble is washed the marble seems to be crumbling away when it is sponged downed lightly. This is happening predominantly in the areas where there were green veins in the marble.

1. Could the steam from the steam shower be causing the marble to disintegrate? Possibly the effect of the hot steam on the cold marble?

2. Could the marble be defective?

3. Or is this normal and we should expect some crevices, cracks, and fall out to develop in natural marble that has veins with normal use?

4. Is there a way to prevent this?

Question 2.

Can you use a latex based sealant on marble that was previously sealed with a petroleum based sealant?

Thank you very much for your help and advice.

Marble requires initial sealing and periodic maintenance, usually a wax product. I have found that Roval’s Milano Marble Polish is effective in smoothing out the gloss and protecting the marble. It requires less buffing than most similar products and doesn’t cost an arm and a leg.
