Armor WB15 Low Gloss Water Based Acrylic Concrete Sealer

100% of 100

The Armor WB15 is a low gloss water based acrylic cure and seal that meets or exceeds ASTM 1315 and ASTM C 309 standards. When properly applied, the Armor WB15 will help concrete to properly cure by reducing premature moisture loss. It will also help to reduce deterioration caused by surface abrasion, foot traffic, and spills.

While the Armor WB15 is approved as a cure and seal, it can also be applied to existing concrete and paver surfaces to achieve a long lasting, UV resistant, breathable low gloss finish.

The Armor WB15 can be applied with a 3/8-1/2” nap roller, or an HVLP sprayer. For a consistent low gloss finish, apply two coats spaced 6-8 hours apart. Do not exceed 24 hours apart between coats.

Time Of Day

The Armor WB15 should only be applied in the early evening (around 5 PM or later) when air and surface temperatures are declining, and when the sun is no longer positioned over the surface.

Surface Preparation

The Armor WB15 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.

The Armor WB15 is designed specifically for use on unsealed concrete and concrete paver surfaces, as well as concrete and concrete pavers previously sealed with a water based acrylic. Do not apply this product over a surface previously sealed with a solvent based acrylic, or any other type of film-forming sealer.  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 WB15 to a test area to verify absorption, coverage, compatibility, and project suitability.

Note About Sealing Pavers:

Please note, the Armor WB15 is not a bonding agent. Do not apply the Armor WB15 over loose sand between paver joints because it will not harden or seal the loose sand. The Armor WB15 can be applied over the pavers directly, or the pavers and polymeric sand (if the polymeric sand is newly installed, wait 7 days before sealing), but it can’t and should not be applied over loose sand.

Adding Non-Slip: For best results, apply the Armor non-slip additive with an appropriate hand-held broadcast spreader. 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.


For complete application instructions and safety data, please refer to the Documents tab.

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.
