TSSPRO SEALANT PRODUCTS FOR SLATE

Slate: Slate is a metamorphic rock. It is derived from shale or mudstone that has experienced intense heat or pressure. Slate is made up of parallel foliated plates. Most slates are gray in color and range in a continuum of shades from light to dark gray although it also occurs in shades of green, red, black, purple, and brown.  Slate is known to flake and is considered to be medium to high porosity. Sealing can extend the life of slate while retaining its natural beauty.

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, general stain resistance, general protection.

All of the sealers listed below can be used.  Because slate is porous, and tends to flake many sealant features/sealers can apply, from general protection to color enhancement (it is often considered to look better with a wet look) to densifying and making it stronger resisting flaking.

• TSS100WB-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, high solids, strong beading, will slightly darken/enhance, prevents salt-water erosion, self-cleaning; leaves, grass etc., tend blow/wash off
• 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.
• TSS500-Enhancer, water based, penetrating; repels water, strong beading, prevents efflorescence, enhancing wet look, matte finish – slight to medium darkening
• TSS600-Stabilizer, water based, penetrating; repels water, strong beading, strengthens, prevents efflorescence, slight darkening
• TSS650-Densifier, solvent based, penetrating, repels water, strong consolidation and densification, resists 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
• TSS750-Algae Cure, water based, surface film; repels water, prevents most forms/colors of algae, up to 2-3 year effectiveness
• 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:

• TSS400-Wetlook Gloss, Solvent based, film forming, high performance, high solids, darkens – enhances, gloss finish, wet look, repels water, oil, wine, many stain types  
• TSSG100-Anti Slip Grip, textured, polypropylene particles added to film forming sealants (TSS300 & 400) that reduce slippage especially when surfaces are wet.
