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: 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.

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

• TSS250–NEW-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.
• 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.
• TSS600-Stabilizer, water based, penetrating; repels water, strong beading, strengthens substrates, prevents efflorescence, slight darkening, slight to no enhancement, natural look 
• TSS650-Densifier, solvent based, penetrating, repels water, consolidates and densifies, prevents deterioration, prevents efflorescence, strong beading, slight darkening
• TSS700-ClearSurface, solvent based, penetrating; repels water, prevents black algae (the most common), up to seven-year effectiveness, slight darkening, keeps concrete looking new
• TSS950-Stain Safe, water based, penetrating; good stain resistance, repels water and oil, many nature stains (leaves etc.) caused by oils, repels red wine stains and similar stains when cleaned soon after spill, strong beading, slight darkening
• You may also want to consider:
• 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
• TSSG100-Anti Slip Grip, textured, polypropylene particles added to film forming sealants (TSS300 & 400) 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
