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:

A solvent resistant commercial pump sprayer is recommend 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.

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.

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.

The Armor WL550 is designed for use on unsealed surface, including:

• Poured and broom finished concrete
• Exposed aggregate concrete
• Concrete pavers
• Brick pavers
• Red clay brick
• Flagstone
• Natural stone

The Armor WL550 can be used on a variety of applications, including:

• Driveways, walkways, and pool decks
• Brick and natural stone enhancements on homes and buildings
• Curbing around gardens and walkways
• Retaining walls
• More!

The Armor WL550 is designed to work entirely below the surface and will not leave a visible surface film. It will slightly darken the surface in order to provide a matte wet look. For a more dramatic color enhancement, or to achieve a low gloss or high gloss finish, consider instead the Armor AR350 for a low gloss wet look, or the Armor AR500 for a high gloss wet look.

Color enhancement will vary depending on several factors including surface porosity. We suggest applying a sample of the Armor WL550 first to verify you are able to achieve the desired look.

When properly applied, the Armor WL550 can provide up to 3-5 years of life on an exterior surface before the need to recoat.

While the Armor WL550 is designed to out-last and out-perform similar products on the market, there are several factors that can impact actual product life, including the severity of surface abrasion and level of foot traffic, the porosity of the concrete or pavers, and other factors. Some surfaces need to be sealed every year, while others can go a few years without sealing.

Water Bead: Surface water beading will not occur on all surfaces. While some surfaces may experience an instantaneous bead, others won’t experience a surface water bead at all. Surface water beading is not a sealer benefit. Surface water bead is caused from resin build-up in the surface pores. Once the resin build-up goes away, so will the bead. The Armor WL550 is designed to work entirely below the surface so its benefits are made visible through performance. You will find sealed surfaces dry faster, are easier to clean, and experience less damage caused by freeze-thaw cycles and de-icing salts.
