Stone Countertop Sealing in Texas

Texas Stone Sealers seals natural stone countertops across Texas — granite, marble, quartzite, soapstone, limestone, travertine, and onyx. Texas Stone Sealers' food-contact-rated TSSPRO CLT sealants protect kitchen and bath countertops against oil, food acid, wine, water rings, and cosmetic staining for years on a single professional application.

Stone countertop varieties Texas Stone Sealers seals

  • Granite — igneous stone, generally low-porosity but still benefits from sealing
  • Marble — calcium carbonate, soft and acid-reactive; sealing essential
  • Quartzite — metamorphic, harder than granite, microscopic porosity
  • Soapstone — talc-based, non-porous but darkened with treatment
  • Limestone — soft, porous, vulnerable to citrus and wine
  • Travertine — calcium carbonate, pitted, requires care around food acids
  • Onyx — translucent calcite, premium but reactive

The water test

Most homeowners don't know if their countertop needs sealing. The test is simple: place a few drops of water on the surface and wait 10 minutes. If the water darkens the stone, leaves a visible mark, or disappears entirely, the countertop is absorbing — meaning it's also absorbing oil, wine, juice, and anything else that spills. Texas Stone Sealers performs absorption testing on-site at no charge.

The Texas Stone Sealers countertop process

Texas Stone Sealers cleans countertops with pH-neutral, food-safe cleaners, removes any existing failed sealant residue, ensures full drying, and applies a food-contact-rated TSSPRO CLT sealant. The sealant cross-links inside the stone matrix and provides 3–7 years of protection depending on stone type and use intensity.

Sealed countertops are still food-safe

Texas Stone Sealers uses food-contact-rated TSSPRO CLT formulations on all countertop applications. The sealant is fully cured and non-toxic before kitchen use resumes. About CLT →
