Sandstone

TSSPRO SEALANT PRODUCTS FOR SANDSTONE

SANDSTONE: is a clastic sedimentary rock composed mainly of sand-sized mineral particles or rock fragments. Most sandstone is composed of quartz or feldspar (both silicates) because they are the most resistant minerals to weathering processes. Sandstone may be any color due to impurities within the minerals, but the most common colors are tan, brown, yellow, red, grey, pink, white, and black. Sandstone is considered very porous and should be sealed.

Considerations for choosing a sealer: The following are all factors for selecting a sealer.  The sealer descriptions below will mention which attributes they have to help in your selection; color enhancing/color change, adding a wet look, minimizing cooking area stains, salt-water erosion resistance, efflorescence resistance, preventing oil (cooking/motor) stains, preventing discoloring mold/algae, preventing deterioration/flaking, adding slip resistance, VOC compliance for requiring states (water base sealers are VOC compliant), moisture content of the substrate, general stain resistance and general protection.

Coverage, Number of Coats:   As mentioned, Sandstone is porous; Two saturation coats of a penetrating sealer should be applied, usually one application if a film forming sealer is used.  Coverage will vary with the sealer selected but will be about 200 sq ft / gallon.  If a second coat is used il generally will get greater coverage.  Testing first is always recommended.

All of the sealers listed below can be used.  Because sandstone is very porous and softer than many stone types and has unique coloring, many sealant features and sealers can apply, from general protection to color enhancement to densifying and making it stronger.

  • TSS100-Salt Water-Proof; solvent based, penetrating, repels water, prevents salt water erosion, strong beading, may slightly darken
  • TSS110-Natural Stone Seal, water based, penetrating; repels water, prevents efflorescence, strong beading, natural look, may slightly darken, good general protection.
  • TSS150-New-StoneSeal Pro, water based, both surface film and penetrating sealer, can be applied to high moisture content substrates, repels water, resists many stains, protects and weatherproofs, ideal for high traffic flow areas.
  • TSS200-Porus Pro; solvent based, penetrating, repels water, high performance, strong beading, will slightly darken/enhance, prevents salt-water erosion, self-cleaning; leaves, grass etc., tend blow/wash off, formulated for porous substrates.
  • TSS600-Stabilizng Sealer, water base, penetrating, high performance, strong beading, strengthens substrates, may slightly darken/enhance, prevents salt-water erosion, best for porous stone.
  • TSS300-Wetlook Low Sheen, solvent based, surface film with penetrating silicone; repels water, oil, wine, many stain types, darkens, enhances colors, wet look, low sheen.  Can add slip grip to reduce slippage
  • TSS360-Wetlook Gloss to Low Sheen, water based, surface film with penetrating silicone; repels water, oil, wine, most stains, medium darkening, enhances colors, low to medium wet look, gloss to low sheen depending on the number of coats.
  • TSS500-Enhancer, water based, matte finish,  penetrating; repels water, strong beading, prevents efflorescence, enhancing wet look – slight to moderate darkening.
  • TSS650-Densifier, solvent based, penetrating, repels water, strong consolidation and densification, resists efflorescence, strong beading, slight darkening

You may also want to consider:

  • TSS400-Wetlook Gloss, Solvent based, film forming, high performance, high solids, darkens – enhances, gloss, wet look, repels water, oil, wine, etc.,
  • TSS550-Stain Safe, solvent based, penetrating, repels water, oil, powerful, premium stain resistance for long periods including red wine, strong beading, slight darkening
  • TSS750-Algae Cure, water based, surface film; repels water, prevents most forms/colors of algae, up to 2-3 year effectiveness
  • TSSG100-Anti Slip Grip, textured, polypropylene particles added to film forming sealants (TSS300 & 400) that reduce slippage especially when surfaces are wet.
