Slate Restoration FAQs

Stripping, cleaning and enhancing slate floors and patios.

Slate Cleaning, Sealing & Repair Services

Slate restoration in Chicago usually means undoing years of the wrong products. Layers of acrylic topical sealer yellow, peel and trap dirt, leaving the floor looking blotchy and powdery. As professional slate floor cleaners in Chicago, we strip those coatings, deep-clean the natural cleft texture and the grout lines, and rinse the floor completely. Slate tile cleaning in Chicago is followed by a color-enhancing or natural-look penetrating sealer, depending on the finish you want. Slate floor restoration in Chicago also includes re-grouting, re-setting loose pieces and slate tile repairs in Chicago for flaking or cracked tiles in kitchens, entryways, sunrooms and exterior stairs.

Common questions about slate restoration

Can you strip old coatings and reseal slate floors?

Yes. Stripping failed acrylic and wax coatings is the most common part of slate restoration in Chicago. We use stone-safe strippers, agitation and extraction to remove every layer, let the floor dry fully, then apply a penetrating sealer or color enhancer that will not peel like the old topical finish.

Why does my slate floor look dull or powdery?

A dull, chalky slate floor is usually a worn topical sealer, efflorescence pushing minerals to the surface, or natural spalling of the cleft layers. Professional slate floor cleaners in Chicago identify which one you have; in most cases stripping, cleaning and resealing restores a rich, even color.

Why does my slate floor look chalky or cloudy?

That cloudy layer is usually old topical sealer or wax breaking down. We strip it completely, deep clean the stone and grout, and apply a fresh penetrating or enhancing sealer so the natural color returns.

Can you stop slate from flaking?

Some slate naturally spalls in thin layers. We remove loose flakes, clean and consolidate the surface, and seal it to slow the process. Badly delaminated tiles can be replaced and blended with the rest of the floor.

Do you restore exterior slate patios and walkways?

Yes. Exterior slate is pressure washed, treated for algae and mineral deposits, re-pointed where grout has failed, and sealed with a breathable exterior sealer that tolerates Chicago freeze-thaw cycles.
