SPEC HARD is a proprietary, colorless chemical solution that increases the wear surface strength of concrete floors subjected to pedestrian and vehicle traffic. SPEC HARD penetrates concrete surfaces to seal, densify and harden. SPEC HARD floors last longer, cost less to maintain, are safe to use, and are guaranteed to resist dusting for years after application. It is V.O.C. compliant, odorless, environmentally safe and simple to apply. SPEC HARD penetrates the concrete surface and undergoes a chemical reaction that turns the concrete substrate into a hardened, densified mass. Surfaces treated with SPEC HARD are not only more abrasion resistant, but are more resistant to chemicals and water than untreated concrete. The deeply penetrating chemical action leaves no film and will not alter the natural non-slip texture of the concrete floor.

Features and Benefits:

• Reduces porosity and increases hardness of the concrete surface.
• V.O.C. compliant
• Resists penetration of oil and many chemicals
• Minimizes tire marks and makes them easier to remove
• Equipment can be cleaned with water
• Can be applied to fresh, new, or existing concrete
• Low sheen enhances the appearance of concrete surface
• Compatible with SpecChem Spec Tilt bond breakers for tiltup projects

Specifications:

• Recommended for ACI 302. Class 1 through 4 concrete floors, and class 9 super flat floor
• USDA accepted
• Typical Properties
  • Active Ingredients: 100%
  • Type: Proprietary blend
  • Flash Point: None
  • Odor: None
  • Color: Clear
  • Dry Time: 2-4 hours
  • VOC: 0.0

Application:

Sealer/Densifier Application:

Coverage:

• Hard Troweled Finish 200-350 ft²/gal
• Broom or Float Finish 150-250 ft²/gal
• Rough Slab Finish 150-200 ft²/gal
• Old Concrete 150-250 ft²/gal

The exact coverage depends upon the porosity and roughness of the slab. If the concrete is extremely porous or rough, more than one coat may be necessary. Application temperature above 40o & rising is recommended.

Application to Existing Concrete:

Surface preparation: Surface must be clean and sound. Remove all dirt, grease, curing compounds or other foreign matter with SpecChem Citrus Cleaner. Completely rinse any residue away and allow to dry. Surface must be completely dry to allow for penetration of SPEC HARD.
