  • PROFESSIONAL GRADE SILANE SILOXANE SEALER: The Armor SX5000 is a professional-grade solvent-based silane siloxane sealer designed for use on unsealed concrete, brick, paver, bluestone, flagstone, slate, natural stone, and masonry.
  • REDUCES WATER ABSROPTION BY UP TO 95%: The Armor SX5000 chemically reacts to form a water-repellent barrier below the surface that will reduce the absorption of water and other liquids by up to 95%.
  • WON’T CHANGE THE LOOK OR COLOR: Formulated with high-quality US-manufactured resins, the Armor SX5000 is designed to protect concrete, brick, pavers, stone, and masonry without changing the look, color, or feel. The substrate will look and feel exactly as it did before it was sealed!
  • LONG LASTING PROTECTION: The Armor SX5000 Silane-Siloxane concrete sealer chemically reacts to form a water-repellent barrier below the surface that can last for up to 7-10 years. By reducing the absorption of water through the surface, damage caused by water absorption is also reduced. Sealed surfaces are more resistant to cracking, spalling, ice damage, salt damage, organic surface growth, and staining.
  • READY TO USE: The Armor SX5000 is ready-to-use and can be applied to a properly cleaned and prepped unsealed surface with a solvent-resistant pump sprayer. One gallon covers up to 175-225 square feet per gallon. Foundation Armor cleaners and sprayers are available separately.
  • EASY TO MAINTAIN: The Armor SX5000 works entirely below the surface so there is no surface film or coating to maintain. When it is time to reseal, simply apply 1-2 coats of the Armor SX5000 to a clean, dry, and absorbent surface with a pump sprayer.
  • READY TO USE: Our ready-to-use concrete sealer can be applied to a properly cleaned and prepped unsealed surface with pump sprayer. One gallon covers up to 175-225 ft2/gallon. Foundation Armor cleaners and sprayers are available separately.

Armor SX5000 Solvent-Based Silane Siloxane Sealer for Concrete & Masonry

The Armor SX5000 is a penetrating solvent-based Silane-Siloxane sealer. It penetrates deep into the substrate where it chemically reacts to form a hydrophobic barrier within the pores that reduces surface water absorption by up to 95%. It will not change the look or color of the substrate, and it won't leave a visible surface film. It is a great sealer for unsealed concrete, pavers, brick, natural stone, and porous masonry. If you prefer a water-based version, consider the Armor SX5000 WB.

How To Apply

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. Two coats are suggested for even coverage and appearance. Less porous surfaces, such as bluestone, flagstone, and slate, may only require one coat.

Surface Preparation: The Armor SX5000 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 SX5000 to a test area to verify absorption, coverage, compatibility, and project suitability.

The Armor SX5000 is designed specifically for unsealed concrete and masonry surfaces. Do not apply this product over a surface recently sealed with a penetrating sealer, or previously sealed with a film-forming sealer or coating. The Armor SX5000 can be applied over surfaces treated with a Silicate sealer so long as it has been at least 7 days. It can also be re-applied to a surface previously treated with a Silane-Siloxane sealer so long as it has been a few years, and the surface is able to quickly and easily absorb water.

Application: An acetone-resistant commercial pump sprayer is recommended to achieve the best coverage and results. Be sure the psi is no greater than 20. Use a .3-.5 GPM adjustable cone tip. Sprayer Suggestion: Armor Industrial Sprayer, ASIN B0CDXT17PD. Apply the first coat of Armor SX5000, ensuring the entire surface is evenly saturated. Wait at least 10-15 minutes, then apply the second coat. Do not flood the surface or allow puddles to form, this will result in over application and the formation of dark spots on the surface. Less porous surfaces, such as bluestone, flagstone, and slate, may only require one coat.

Substrates sealed with Armor SX5000 may be coated with silicone emulsion paints and many oil based paints once the surface has had 72 hours to dry. Testing is always necessary and recommended to assure proper adhesion. Adhesion may be improved if the surface is pressure washed and allowed to dry prior to application. Armor SX5000 is not a paint primer. Adhesion of cementitious coatings, stucco, plaster, etc., may be adversely affected. These types of substrate treatments should be installed and allowed to fully cure before applying Armor SX5000. Always test to verify compatibility.

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 warm water and soap. Dispose of containers in accordance with local and federal regulations. Product Removal: Armor SX5000 penetrates deep into to the surface. Removal is not recommended.

Technical Data Sheet: Prior to applying, please refer to the Technical Data Sheet and Safety Data Sheet posted on the manufacturer's website. If you have questions before purchasing or applying, please don't hesitate to reach out to a Foundation Armor Representative.
