Marble & Stone
Sealing
Manhattan · New York City
Marble is porous — left unsealed, it drinks up oil, wine, coffee, and cleaners and etches at the first splash of lemon. We seal it so stains bead and roll off. For countertops we use StainZero — the clear, non-yellowing, safer anti-etch sealer that keeps your stone looking natural.
What we seal
The surface people forget about.
Until it's stained.
Countertop Anti-Etch Sealing (StainZero)
The sealing we recommend for every marble kitchen and bath counter. StainZero resists acid etching from lemon, vinegar, wine, and cleaners — and it stays clear, never yellows, and is safer than the competition, so your stone keeps its natural look.
Floor Sealing
Marble, travertine, and terrazzo floors sealed against spills, tracked-in grime, and daily wear — so the polished finish you invested in stays protected instead of absorbing stains.
Shower & Vanity Sealing
Bathroom marble takes the worst of it — hard water, soap, and humidity. We seal shower surrounds, vanities, and tub decks so they resist hard-water etching and soap-scum staining.
Impregnating & Penetrating Sealers
For stone that needs deep protection, we apply commercial-grade impregnating sealers that penetrate below the surface to block oil, water, and moisture from the inside out.
StainZero — the anti-etch seal
Seal against stains.
Seal against etching.
A standard sealer stops a stain. StainZero also stops the etch — the dull white ring that acid leaves on marble the moment lemon, vinegar, or wine touches it. That's what makes it anti-etch, not just stain-resistant.
Clearer — looks more natural.
No milky film, no waxy buildup. Your marble reads as the natural stone it is — veining, depth, and color all come through exactly as they should.
Non-yellowing — for years.
Lower-grade sealers oxidize and turn dingy on white and Carrara marble. StainZero resists yellowing, so the bright look we seal is the look that stays.
Safer than the competition.
No harsh fumes, no toxic curing process. Protection you can feel good about in a kitchen you cook in every day.
