Liquid Densifier for Concrete #2130

Product Description

ARMOR SEAL contains an odorless solution of specialized chemicals that penetrate concrete to seal, densify, and harden it. It is water-based, environmentally safe and VOC compliant. This solution of chemicals penetrates into the concrete where it reacts with free calcium to form insoluble calcium silica hydrate, which makes concrete more water, stain and abrasion resistant. This process makes for easier maintenance and longer life of the surface.

Directions for Use

Coverage Rate: Estimating Guide-First Coat: 200 sq. ft/gal. Second Coat: 300 – 400 sq. ft/gal (if necessary). Texture and absorption of surface will determine final coverage rates. Porous concrete surfaces may require additional material.

Drying Time:  Approximately 2-4 hrs at 70°F. Allow treated area to dry before opening to traffic. Dry time is temperature, humidity, and wind dependent.

Note:  The use of a mechanical scrubber will increase the effectiveness of the application. The treated surface will develop a “polished” appearance over time.

For colored concrete, a test application is recommended.

Surface Preparation: All surfaces to be treated must be clean, sound and absorptive. Remove all membrane forming curing compounds, sealers, oil, grease, dirt and other contaminants. Remove any concrete laitance and patch or fix all cracks and damaged areas. New concrete should be properly cured a minimum of 7 days in accord with ACI 302 by one of the following methods:  water, plastic sheeting, reinforced paper or membrane-forming cure. If a membrane-forming cure is used it will require removal prior to the application of the Armor Seal. It is recommended to use a Pro Chem Citrus Cleaner for the removal of those curing compounds or curing & sealing membranes.

Mixing:  Mix thoroughly prior to each use.

Placement: Apply ARMOR SEAL to point of rejection (by spray, roller, brush or pouring), then scrub the product using a soft bristle broom or mechanical scrubber.  Work in this manner until the product begins to thicken, usually in 15-30 minutes, depending on the surface and ambient temperatures, then rewet with water and work for another 5-10 minutes.

Do not allow ARMOR SEAL to dry, apply additional product if needed to keep wet while working.  Thoroughly rinse and then squeegee or brush off excess material until dry.  On porous or rough surfaces, a second application may be required.  If a second coat is required, immediately apply it in a similar manner as the first coat.  Do not allow the treated surfaces to dry between applications.

CLEAN UP: Immediate and thorough flushing with clean water while material is still wet.  Dried material may require sanding or grinding for removal.

MAINTENANCE: Mop or use mechanical scrubbing with detergents or water.  Mopping or scrubbing the floor will prolong the life of the floor, as well as increase the “polished” look.  Wipe up chemical spills as soon as possible.

FOR PROFESSIONAL USE ONLY. Ponded or puddled material must be removed by squeegee or brush, otherwise white residue will appear on the surface.  If white residue starts to appear on the surface during drying, immediately remove with hot water and scrubbing.  Floors are slippery during application.  Porous, low quality concrete substrates or floors with a rough surface may not develop a “polished” appearance over time.  Apply only when temperatures are above 40°F (4°C).  Avoid contact with glass, aluminum and polished metal surfaces.  Protect from contact.  If contact occurs, wash immediately with water to prevent etching.  For colored concrete a test installation is recommended.
