Uses: The Armor WL550 is designed specifically for unsealed surfaces with a variation in colors that need a very slight color enhancement such as brick, integrally colored pavers, flagstone, bluestone, integrally colored stamped concrete, and other types of natural stone. This product should not be used on broom finished concrete, uncolored concrete, uncolored pavers, or any substrate that doesn’t have a variation in color. If you need a consistent or dramatic wet look finish and are looking to seal concrete or concrete pavers, the Armor AR350 or Armor AR500 are better alternatives.
Coverage: Porous Surfaces: Up to 175 FT2/gallon in one coat. Smooth Surfaces (once properly prepped): Up to 200-225 FT2/gallon in one coat. Coverage will vary depending on porosity, surface condition, application method, and the amount of material applied by the applicator. The above coverage rates are estimates and will vary. In most cases, a single coat is needed. For porous substrates, or if you notice an inconsistent wet look, a second coat can be applied. Samples are available on Amazon for testing.
Surface Preparation: The Armor WL550 should be applied to a completely clean and dry surface. If the surface was cleaned with water or pressure washed prior to application, allow the surface to dry for at least 24 hours before sealing. While the surface may appear dry and feel dry to touch, water below the surface trapped in the pores can cause the same issues. While pressure washing the surface is typically sufficient, spot treatment may be necessary for deep or older stains. If the surface is smooth troweled, or does not easily accept water, acid etching may be required prior to applying sealer. It is always suggested to apply the Armor WL550 to a test area to verify absorption, coverage, compatibility, and project suitability.
The Armor WL550 is designed specifically for unsealed concrete and masonry surfaces. Do not apply this product over a surface recently sealed with a water repellent sealer, or previously sealed with a film-forming sealer or coating.
Application: An acetone-resistant commercial pump sprayer is recommended to achieve best coverage and results. Be sure the psi is no greater than 20. Use a .3-.5 GPM adjustable cone tip.
Apply the first coat of Armor WL550, ensuring the entire surface is evenly saturated. Broom out puddles until surface is penetrated. In most cases, a single coat is needed. For porous substrates, or if you notice an inconsistent wet look, a second coat can be applied. The second coat can be applied while the first coat is still wet, or after surface appears dry.
Substrates sealed with Armor WL550 may be coated with a solvent based acrylic sealer once the surface has had 72 hours to dry.
Time of Day: The temperature of the air and surface must be 55-85 degrees F during application. If freezing conditions exist prior to application, it is highly recommended that the substrate be allowed to fully thaw. Should this recommendation not be followed, the product may not yield adequate protective properties.
Once applied, the surface should be kept dry for at least 24 hours.
Non-Slip Additives: The Armor WL550 is a penetrating sealer and works entirely below the surface. Non-Slip additives CAN'T be added to this product because there isn't a surface film for the non-slip additive to be suspended into. Penetrating sealers will not change the surface traction of the concrete, brick, natural stone or pavers - the surface will feel exactly as it felt before being sealed. Clean-Up: Use xylene or acetone. Dispose of containers in accordance with local and federal regulations. Product Removal: Armor WL550 penetrates deep into to the surface. Removal is not recommended.
