Natural Stone Sealers for Marble, Slate, Travertine, Limestone, Granite, Basalt, Flagstone and All Other Stone's
Protect your stone from stains, moisture, salt, etching, oils, and everyday wear with professional-grade penetrating sealers designed specifically for natural stone.
Why Natural Stone Needs a Specialized Sealer
Natural stone is porous and vulnerable — even the hardest granite's and quartzite's absorb staining liquids like oils, or dull from acid sitting on the surface causing etches over time.
Stone like marble, travertine, and limestone can etch or stain within minutes if unsealed.
Our natural stone sealers are formulated to:
- Repel oil, grease, wine, coffee & organic stains
- Prevent winter salt damage
- Reduce water absorption and moisture issues
- Stop discoloration and “wet-looking” spots
- Preserve stone’s natural color (or enhance it — your choice)
- Last longer than hardware-store sealers
These formulas are stone-safe, non-acidic, non film forming, breathable, and long lasting.
Not Sure Which Sealer You Need?
Choosing the right sealer depends on:
- The type of surface (stone, tile, concrete, paver)
- The finish you want (enhancing or natural)
- Whether it’s indoors or outdoors
- Exposure to salt, oils, moisture, or freeze–thaw cycles
- Whether you’re sealing old or new surfaces
If you want help choosing the right product, we can guide you.

Frequently asked questions
Does natural stone really need to be sealed?
Yes — stone is porous and absorbs liquids, oils, minerals & contaminants without protection. Sealing and maintaining your stone can extend the life span of natural stone by decades to centuries.
How often do I need to reseal?
Most natural stone requires resealing every 7-10 years depending on use when using the high quality sealers provided by StoneSealer. Some even come with an available sealer performance warranty of up to 25 years.
Will the sealer change the color of my stone?
Only enhancing sealers deepen color. Natural-look sealers like Stain-Proof Premium or AquaBlocka do not alter appearance.
Can I use these on polished marble?
Yes — penetrating sealers are safe for polished surfaces. If in doubt, have a professional installer inspect the stone for having a high gloss coating rather than a natural polish, as this could have a negative interaction with a further coat of nano sealer.
Do you offer contractor or distributor discounts?
Yes — we provide bulk pricing, pallet pricing & wholesale programs for professionals.
