How to Restore a Nolla Hydraulic Floor

Restoring a Nolla mosaic floor requires careful treatment. The process involves deep cleaning to remove dirt and old waxes, repairing or replacing damaged parts, leveling with mortar, gently polishing, and applying a protective sealant or varnish.

Step 1

Thorough cleaning

Before doing anything, remove dust and dirt. Do not use bleach, ammonia or strong acidic products directly, as they would damage the material.

  • Use a specific cleaner (such as Sanigel) or a neutral soap with warm water.
  • Scrub with a soft brush or scouring pad to remove surface stains.
