| Problem and Solution: |
|
Dissolved iron and calcium in the water have stained this polished marble shower.
Although marble is relatively dense and waterproof, dissolved minerals can easily penetrate the microscopic fissures between the marble crystals. Because these stains penetrate the surface of the stone, the stone must be resurfaced.
Resurfacing involves grinding off the calcium deposits and stained marble.
Grinding leaves a rough surface that requires skillful, machine polishing with up to 8 successively finer grit diamond wheels, and polishing pads.
Appropriate professionally applied sealers, renewed at each annual cleaning, and use of a squeegee after each shower can delay new damage.
