Marble requires much more preventative maintenance than granite or Quartz. It is softer and remarkably more porous by nature, making it more susceptible to scratching, chipping and especially staining. Acidic substances (lemon juice, vinegar, wine, etc.) damage marble by etching into the surface. Marble needs to be sealed frequently – every six months is a reasonable expectation – and even when it is properly sealed it remains easily damaged. It is important to be aware of the maintenance related to marble, and to consider the typical daily uses of the areas you are considering installing it in.
