Why Natural Stone Needs Professional Protection

Stone surfaces such as marble, limestone, travertine, granite, slate, and flagstone are naturally porous. Without proper sealing and protection, they can suffer from:

  • Staining from spills, oils & moisture
  • Acid etching from food, drinks & cleaners
  • Water absorption & darkening
  • Surface wear in high-traffic areas
  • Permanent damage requiring restoration

Professional sealing and protective treatments create a barrier that helps prevent damage before it occurs.

Our Stone Sealing & Protection Services

Below are the most common natural stone surfaces we service. Each type responds differently to restoration techniques, which is why expertise matters.

1. Penetrating Stone Sealing

We apply premium, stone-specific penetrating sealers that absorb into the stone to:

  • Reduce staining and moisture absorption
  • Maintain the natural look of the stone
  • Improve cleanability and longevity

Ideal for floors, showers, countertops, walls, and exterior stone.

2. MORE® AntiEtch® Protection

MORE® AntiEtch® is an advanced, invisible surface protection designed specifically for calcite-based stones such as marble, limestone, and travertine.

Benefits include:

  • Protects against acid etching from food, beverages, and cleaners
  • Reduces scratching and surface wear
  • Preserves the natural appearance (no coating or shine change)
  • Ideal for kitchen countertops, vanities, tables & high-use surfaces

This treatment dramatically reduces the need for frequent restoration.

  • Easy-to-clean, low-maintenance surface
  • Suitable for granite, marble, quartzite, and other natural stones

StoneGuard® helps keep countertops looking newer for longer.

Our Sealing & Protection Process

  • Surface Evaluation – We identify stone type, porosity, finish, and usage patterns.
  • Professional Cleaning – Stone is deep cleaned to ensure proper bonding of protective treatments.
  • Application of Protection – We apply the appropriate sealer or protection system based on your needs.
  • Curing & Final Inspection – Treatments are allowed to cure properly for maximum effectiveness.

Did You Know?

  • Sealing does not make stone stain-proof—it makes it stain-resistant, buying you valuable cleanup time.
  • Acid etching cannot be stopped by standard sealers, which is why AntiEtch® protection is essential for marble and limestone.
  • Many countertop replacements happen due to preventable damage that professional protection can avoid.
  • Properly protected stone requires less frequent restoration, saving money long-term.
