TSSPRO SEALANT PRODUCTS FOR FLAGSTONE

FLAGSTONE: Flagstone is the general term used to refer to a number of sedimentary and metamorphic rocks. These types of stone are called flagstone because they tend to split easily into flat segments that can be used to pave walkways. When someone refers to a rock as “flagstone,” they are not referring to the stone’s proper name, only to its suitability for use as a paving tone. Flagstone is generally of medium porosity but varies and comes in a variety of colors. Flagstone will look better and last longer if 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, Flagstone has varying porosity; generally one saturation coat is sufficient but if absorbed quickly, then a second coat should be given. 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.

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

  • 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 although may slightly darken some stone, best for non-porous stone.
  • TSS150-StoneSealPro, water based, both surface film and penetrating sealer, can be applied to high moisture content substrates, repels water and many stains, slightly darkens, natural matte finish, leaves non-stick surface that easily cleans with wind or water.
  • TSS200-Porus Pro; solvent based, penetrating, repels water, high performance, strong beading, can darken/enhance, prevents salt-water erosion, self-cleaning; leaves, grass etc., tend blow/wash off, formulated for porous substrates.
  • 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.
