Limestone

TSSPRO PRODUCTS FOR LIMESTONE

Limestone: Limestone is very porous and prone to efflorescence and discoloring black algae. Limestone comes in white and other shades and also with colored veins and mineral deposits. Limestone types include Lueders, Freska, Austin Chalk, etc. Limestone is extremely prone to discoloring with black algae/mold over time and can generate efflorescence. Limestone should be sealed to preserve its beauty and composition.

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: Limestone is porous and will absorb sealant; generally, two coats are recommended. Coverage will vary with the sealer selected and will vary from 150 sq ft / gallon to 200 sq ft / gallon. The second coat will generally get greater coverage.

All of the sealers listed below can be used depending on the sealer feature desired.

  • TSS250 – SteelcretePro, water based, both surface film and penetrating sealer, can be applied to high moisture content substrates, repels water and many stains, densifies/strengthens, prevents efflorescence, slightly darkens, natural matte finish, leaves non-stick surface that easily cleans with wind or water.
  • TSS600 – Stabilizer, water based, penetrating; repels water, strong beading, strengthens substrates, prevents efflorescence, slight darkening, slight to no enhancement, natural look
  • TSS700 – ClearSurface, solvent based, penetrating; repels water, prevents black algae (the most common), up to seven-year effectiveness, slight darkening, keeps concrete looking new
  • TSS550 – Stain Stop, 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 (green, black etc.), up to 2–3-year effectiveness
  • 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.

You may also want to consider:

  • TSS650 – Densifier, solvent based, penetrating, repels water, consolidates and densifies, prevents deterioration, prevents efflorescence, strong beading, slight darkening
  • TSSG100 – Anti Slip Grip, textured, polypropylene particles added to film forming sealants (TSS300) that reduce slippage especially when surfaces are wet.

For Cleaning

  • TSS010 – Cleaner, water based, concentrate, formulated for cleaning limestone, concrete, grout haze and efflorescence, removes most any stain or discoloration
  • TSS015 – Neutralizer; use after TSS010 to neutralize the surface prior to sealing
