SealThane Paver Sealer

SealThane is a heavy-duty, joint stabilizing, high gloss, deep color enhancing two component urethane sealer for brick pavers, stamped and decorative concrete surfaces and is used as a top coat for epoxy flooring. SealThane provides ultimate protection against foot traffic and vehicular traffic alike while inhibiting mold and algae growth. SealThane is a unique formula that binds the joint sand between brick pavers inhibiting weed growth, ant mines, and joint sand loss. SealThane also protects decorative vinyl flakes on epoxy floors with its non-yellowing properties and is used for outdoor epoxy coatings to inhibit color fading. SealThane may be applied to damp surfaces which allows for same day cleaning and sealing.   

  • For use on Concrete Surfaces including Brick Pavers, Driveways, Garage Floors, Walkways, Patios, Slate, Saltillo Tile and Clay Roof Tile.  Also may be used as a non-yellowing, clear sealer to protect decorative vinyl flakes on concrete floors.


  • Dirt, grease, grime and any foreign material must be removed before application of new coating.  Treat surface for mildew.  Oil and grease should be scrubbed with a solution of OxiClean and water or alternate degreaser.  Contact a Store representative for detailed surface preparation specifications.


  • Combine Part A & Part B and mix thoroughly with gentle agitation for 2-3 minutes.  Do not whip air into the material.  SEALTHANE  has a 2-3 hour pot life once Part A & Part B are combined, therefore, do not mix more than you can apply in that time frame.  Apply with brush, roller, airless sprayer or garden sprayer.  When spraying, use a tip designed for gloss coatings.  Apply when surface and air temperatures are above 50 Deg. F.  Do not apply if the threat of rain exists or if moisture or dew may condense on the surface prior to SEALTHANE curing.  Cover and protect all vegetation and surrounding areas not being sealed.  Do not over apply, soak the substrate or allow product to puddle.  Two thin coats are recommended for best performance.  A second coat may be applied when the first coat is dry to the touch.  Do not apply additional coats 36 hours after the first coat was applied.
  • Gloss is determined by the mix ratio you select.  Less water will yield a higher gloss.  Note, SEALTHANE must be reduced with water – DO NOT APPLY UNDILUTED.  Select a mix ratio for the desired result.


  • Mix Part A, Part B and water
  • For Maximum Performance:  
  • 4 Parts A 
  • 1 Part B
  • 2 Parts Water
  • Maximum Reduction Ratio:
  • 4 Parts A
  • 1 Part B
  • 5 Parts Water
  • Two coats are recommended – flood coat and a a top coat (Additional coats may be required to achieve the desired finish)
  • Flood coat dilution is 3 parts water to 1 part concentrated sealer 
  • Top coat dilution is 2 parts water to 1 part concentrated sealer

For freshly poured concrete: Apply after concrete sets for at least 24 hours. Make sure no water puddles are present. Concrete may be slightly wet before applying.

For fully cured concrete: Remove all dirt, wax, dust, mildew, and loose or scaling material with a scraper, wire brush, or stiff bristle brush. Grease, wax, and oil should be removed by scrubbing with CLEAR PINK STUFF or a heavy duty detergent in warm water. Rinse thoroughly with clean water. Allow to dry. If using a pressure washer, do not use on a pressure setting above 1750 psi to avoid damaging the concrete. Remember, concrete acts like a sponge – pressure washing and general cleaning may trap residual moisture in the concrete. To check for trapped moisture, tape a 12”x12” piece of 3 mil plastic or aluminum foil tightly on all four edges to the surface. Remove it after 24 hours. If the floor side of the plastic or foil is damp, allow additional drying and repeat the test.

EFFLORESCENCE: A white, powdery, crystal-like deposit visible on the masonry surface, should be removed. CLEAN UP EFFLORESCENCE REMOVER or muriatic acid, used according to manufacturer’s directions, are effective efflorescence removal agents. All masonry surfaces are subject to occurrences of efflorescence. Properly prepared concrete should look and feel like medium grit sandpaper. If concrete remains smooth, repeat etching procedure. Test concrete porosity by sprinkling a few drops of water on to the surface in several areas. If the water is readily absorbed, you are ready to paint. If it beads or lays on the surface, additional cleaning and etching is needed. Rinse thoroughly with clean water and allow to dry for 24 hours.

NOTE: Rinse etching solutions thoroughly. Etching solutions allowed to dry on masonry surfaces prevent proper curing of ECO SHIELD DRY LOOK PENETRATING CONCRETE SEALER and may result in the ECO SHIELD DRY LOOK PENETRATING CONCRETE SEALER appearing milky when dry. Patch all holes and cracks with a masonry crack filler or a suitable cement-based patching compound. Be sure to smooth the patch evenly. Allow the patched area to dry thoroughly.


Apply only when air and surface temperature is above 50° F and humidity below 70%. Do not apply if raining or if it will rain within 48 hours of application. ECO SHIELD DRY LOOK PENETRATING CONCRETE SEALER appears milky in the pail but dries clear. Apply by brush, roller, spray, or squeegee. Spread evenly – do not allow puddles or a heavy surface film to
occur. Apply one coat using thin even strokes. Extremely porous surfaces may require a second coat. Allow 6 hours drying time between coats. Additional coats will cause surface to be
slippery when wet. On light-colored surfaces, some darkening may take place; test in an inconspicuous area to be sure darkening does not occur. May be applied to surfaces previously coated with a similar treatment. For best results, test a small area for proper adhesion prior to coating entire surface.

Due to variations in porosity, when applied over flagstone, slate, terrazzo, dense smooth or light colored concrete, thin with clean, moderately warm water 10%—20% to minimize sheen.

In addition, light colored concrete may darken unevenly due to variations in porosity. Test on a small area to see final effect.
