The Armor AR350 can be applied with a 3/8-1/2” nap roller, or a solvent resistant commercial pump sprayer. For a consistent wet look and low gloss finish, apply two coats spaced 24 hours apart.

Time Of Day

The Armor AR350 should only be applied in the early evening when air and surface temperatures are declining, and when the sun is no longer positioned over the surface. To avoid bubbling and hazing, do not apply in the morning or middle of the day.

Surface Preparation

The Armor AR350 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 pressure washing the surface is typically sufficient, spot treatment may be necessary for deep or older stains.

The Armor AR350 is designed specifically for use on unsealed concrete and concrete paver surfaces, as well as concrete and concrete pavers previously sealed with a solvent based acrylic. If the concrete is smooth or trowel finished, and doesn’t quickly and easily absorb water, other surface preparation may be required to open up the surface pores, such as acid etching or grinding.

The Armor AR350 should not be used to seal clay brick, red Chicago pavers, flagstone, slate, or natural stone. If you are looking to seal clay brick, red Chicago pavers, flagstone, slate, or natural stone, consider instead of the Armor WL550 or the Armor SX5000 WB.

Note About Sealing Pavers:

Please note, while the Armor AR350 can be applied over paver joints, it is not designed as a bonding agent and will not harden or bond the loose sand in the paver joints. If applying with a roller, loose sand in the joints may cling to the roller and be redistributed across the pavers. For best results, apply first coat with a sprayer if you are applying to pavers with loose sand in the paver joints.

When applying to porous pavers, gloss level may be reduced, and more material may be required to achieve desired finish.

Mixing Opaque Color Packs: Do not exceed more than 6 ounces of color per gallon of sealer. Stir color well before adding to sealer, then once added to sealer, stir again, ensuring color is evenly mixed. Once cured, will cover like a paint—you will be left with an opaque colored finish.

Mixing Semi-Transparent Color Packs: Do not exceed more than 1 ounce of color per gallon of sealer. Stir color well before adding to sealer, then once added to sealer, stir again, ensuring color is evenly mixed. Once cured, will offer a semi-transparent tinted finish.

Adding Non-Slip: For added surface traction, the Armor Non-Slip additive can be added. The ultra-fine, fine, and coarse Armor Non-Slip additives works best in the Armor AR350.  Applying the Ultra-Fine: Slowly drill mix 3-6.5 ounces of non-slip additive per gallon of sealer, until completely blended, then apply. For Fine and Coarse: When applying the second coat, add the non-slip additive to the coating using a broadcast spreader, and back roll to encapsulate the non-slip additive.

Clean-Up

Use Xylene or acetone. Dispose of containers in accordance with local and federal regulations.

Product Removal

Dried, cured sealer may be removed with a the Armor CR100, or by using a diamond grinding method, sandblasting method or similar mechanical action.

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. Two coats are suggested for even coverage and appearance.

The Armor AR350 is a great choice for a variety of interior and exterior concrete applications, including:

• Pool decks and patios
• Driveways, walkways, and stairs
• Garage and basement floors
• Carports and pole barn floors
• Much more!

The AR350 can be applied to a variety of interior and exterior concrete surfaces, including:

• Stamped concrete
• Poured and broom finished concrete
• Exposed aggregate concrete
• Concrete pavers

The Armor AR350 is designed specifically to be used on unsealed concrete and concrete pavers. It can also be applied to concrete and concrete paver surfaces previously sealed with a solvent based acrylic. The Armor AR350 should not be used to seal clay brick, red Chicago pavers, flagstone, slate, or natural stone. If you are looking to seal clay brick, red Chicago pavers, flagstone, slate, or natural stone, consider instead of the Armor WL550 or the Armor SX5000 WB.

The Armor AR350 can’t be applied over any other film forming sealer, other than a solvent-based acrylic sealer. It can’t be applied over a water based acrylic, an acrylic latex, a paint, epoxy, or urethane.

The Armor AR350 ships in clear and offers a low gloss finish. It will darken surface, giving it a similar appearance to being wet. Armor Opaque Acrylic Color Packs can be added for a tinted opaque low gloss finish, and Armor Semi-Transparent Acrylic Color Packs can be added for a tinted semi-transparent low gloss finish.

The actual level of gloss and enhancement received will depend on the type and age of the surface, age, porosity, condition, applicator, application method, and amount of material applied. For an accurate representation of what your surface will look like once sealed, we suggest applying the product to a test area first.

When properly applied, the Armor AR350 can provide up to 1-3 years of life on an exterior surface before the need to recoat, and up to 2-7 years of life on an interior surface.

While the Armor AR350 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 the amount of resin build-up on the surface. Some surfaces need to be sealed every year, while others can go a few years without sealing.
