Pittsburgh Stone Floor Restoration

A natural floor can be made of Marble, Granite, Travertine, Terrazzo, Onyx, or Limestone – just to name a few.  The stone floor restoration process varies by the type of stone and the final finish that is desired, whether polished or honed.

Simply cleaning and polishing the marble will not remove wear from traffic or etches, (which are “spill” marks caused by acidic liquids coming into contact with the floor).  To remove these, the stone must be restored by bringing it “down” to remove the damage, then back up in order for it to take a polish.  (It’s a similar idea as restoring damaged wood furniture, except instead of various grits of sandpaper, various grits of diamonds are used.)

Below are the three steps involved in our Pittsburgh Stone Floor Restoration service:

Step 1 for Stone Restoration: Protecting the areas

We take the set-up/protection step seriously, masking off walls and fixtures for protection.  Our goal is to keep your whole home looking good, not just the area we are working on.

Step 2 for Stone Restoration: Removal of Damage

Restoration is the process is to remove moderate scratches and etches to bring the marble back to a nice shine. It uses water with diamond-bonded metal and resins discs of various grit levels (up to 8) and polishing compounds to remove damage, then bring it back up to a beautiful finish.

We use a wet-process to restore the floor, not a dry-sanding which would create plumes of dust.  However,  the process gets close to the edges,  and it may be necessary for you to have your painter touch-up the baseboards.

Full Restoration & Polishing:   This is a construction-level process is to remove the lippage (uneven-ness of the tiles) and scratches and to bring the floor back to a nice shine.  The restoration process uses water with diamond-bonded metal and resins discs of various grit levels (up to 8) and polishing compounds to basically grind the floor flat, then bring it back up to a beautiful finish.  Full restoration is usually a once-in-a-lifetime process for residential marble floors;  once you have it done, it will make future light-restoration process easier.

Light Restoration & Polishing:   This process is to remove light scratches and etching (dull spots from spills) and to bring the floor back to a nice shine.   The process uses water with diamond-bonded resins and fiber discs of various grit levels (up to 5) and polishing compounds to achieve a beautiful finish to the surface.  We give attention to all edges as well.

Note about light restoration:  It does not remove the lippage, which is the uneven-ness between the tiles — only full restoration can, which is a construction-level project that involves grinding the floor to make it flat.  Because of lippage, some window-paneing may occur, (a difference in surface along the corners and edges of tiles), but usually this is mostly blended out during the polishing process.

Step 3 for Stone Restoration: Obtaining Desired Finish

The final step is to use resin diamond-bonded discs and polishing compounds to bring the floor to the desired finish. That can be a high-polished, reflective finish. Or it can be a honed, matte finish. Afterwards, the floor is sealed with an acid-resistant sealer. No topical coating is ever applied, as natural stone should never have a topical coating. Waxes interfere with the stone’s natural beauty and ruins grout.
