Ultra Seal Penetrating Natural Stone Sealer

Ultra Seal Invisible Stone Sealer – a specific type of natural stone and concrete sealer, designed to help keep water and dirt away from the surface. Made specifically for natural stone, concrete, brick, block, and other aggregate surfaces, Ultra Seal Invisible Stone Sealer will retain its effectiveness even in difficult weather conditions such as heavy rains or extreme heat. Unlike traditional concrete sealers that only allow water to bead on top for up to a couple months after application, Ultra Seal Invisible Stone Sealer is formulated with durable chemical compounds that make water completely roll-off like wax does on your vehicle’s paint. It can withstand alkalis (basic materials) and acids (high leaching substances), meaning you never have to worry about damage inflicted by salt and water infiltration damaging your concrete surfaces.


Ultra Seal Penetrating Natural Stone Sealer



  • Reduces water absorption into the substrate, thus reducing spalling due to freeze thaw and efflorescence, thereby increasing the life of the substrate.
  • Colorless and non-yellowing protection preserves the natural appearance of the substrate.
  • Penetrating & breathable
  • Water based and Environmentally Friendly
  • May be applied to damp surfaces
  • May be painted over
  • Inhibits mold and algae growth
  • Inhibits salt water infiltration

RECOMMENDED USES: For properly prepared, unsealed natural stone, concrete walls, foundations, pre-cast concrete, block, brick and most aggregate surfaces.

SURFACE PREPARATION: Substrate must be pressure washed and cleaned  prior to application of Penetrating Concrete Sealer and Damp Proofer. Surface should be cleaned and treated for organic growth and oil with CLEAR PINK STUFF prior to application. Efflorescence should be treated with CLEAN UP Efflorescence Remover.

APPLICATION INFORMATION: Apply with brush, roller, or pump sprayer. When spraying, use a fan or cone tip designed for water based coatings. Apply when surface and air temperatures are above 60° Fahrenheit and rising. Do not apply if the threat of rain exists within 12 hours.

  • Do not over apply or allow product to puddle.
  • Wet on Wet application – apply product until it begins to repel itself.
  • Wipe off excess.
  • Do not apply to a surface that was previously sealed with a film-forming or topical sealer
  • May be applied to damp surface, however, do not apply when standing water is present
  • May be used as a Moisture Vapor Barrier prior to applying an epoxy coating

Coverage: Coverage will depend on porosity of the substrate. Coverage averages up to 250 square feet per gallon depending on the porosity.

Enhancing Impregnating Natural Stone Sealer is a color enhancing, slow drying, deep penetrating, solvent based acrylic sealer for interior or exterior use. Ultra Seal Enhancing Impregnating Natural Stone Sealer's slow drying nature allows it to penetrate deep before setting. Will enhance the natural colors of most surfaces. Very effective at sealing and protecting dense and smooth surfaces such as quarry tile, ceramic tile, slate, unfinished marble, terrazzo, travertine, smooth cement, and all other cementitious materials. Recommended for use on unglazed surfaces when NO gloss or a SATIN finish with color enhancement is desired.

• Travertine
• Brazilian & Spanish Tile
• Unglazed Tile
• Marble
• Stone, Brick, & Clay Pavers
• Exposed Aggregates
• Quarry Tile

For very porous surfaces: 1st coat: 150-200 sq. ft./gallon.
2nd coat 300-400 sq. ft./gallon.

For average density surfaces: 1st coat: 250-300+ sq.ft./gallon.
2nd coat 400+ sq. ft./gallon.
For very dense surfaces: 1.5x avg. density coverage Generally, the sealer will go twice as far on the 2nd coat as it did on the 1st coat.

Allow 24 hours between coats.


Always be sure surface is clean, dry, and free from any dirt, grease, oil, wax, or other contaminant. Read the entire label before using. Use only as directed. Always test on a small piece of material or a small inconspicuous area to determine suitability. Ensure the area is well ventilated. Ideal surface temperature should be between 60°F and 80°F. Product works best when it is the first substance applied to the surface, insuring proper penetration.


Ultra Seal Enhancing Impregnating Natural Stone Sealer may be applied with spray applicator, brush, roller, or lint free rag. Spread evenly and uniformly- cover entire area, leaving no puddles. Avoid puddles by wiping up excess. Allow 24 hours between coats to ensure it has dried completely.
