Conservation and maintenance

Properly prepared granite does not require frequent conservation. It is important, however, to be aware of a few reasons which can negatively influence the aesthetics of granite products. The appearance of granite surfaces may be spoilt by stains.

The are caused by:

  • granite chemical compounds being activated under the influence of persistent moisture
  • pollution of the base and mortars (metal filings, organic substances, etc.)
  • improper mortar and grout
  • construction technological errors (uncovered reinforcing bars, etc.)
  • contamination caused by the wrong exploitation and cleaning (improper cleaners)
  • calcium efflorescence in leaking places
