Description
PENTRA-HARD Densifier is advanced lithium chemistry that hardens and dustproofs new and existing concrete. This easy-to-use water-based solution requires no rinsing and is VOC compliant in all areas of the world. When sprayed on new or existing concrete, it 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 for easier maintenance and longer life. It is also suitable for concrete polishing procedures and helps prolong the life of polished finishes.
For applications where greater shine and stain resistance is required (schools, restaurants, retail, grocery, commercial, etc.) the Durable Floor SystemTM (DFS) is recommended. For this system, PENTRA-HARD Guard is applied directly over the top of PENTRA-HARD Densifier. Ask your Dayton Superior representative for more details on this product/system

Storage
Keep from freezing. Shelf life is 36 months from date of manufacture, properly stored in original unopened containers.
Surface Preparation:
Surface Preparation: Precautions: Apply only when temperatures will be above 36o F (2o C) for at least 4 hours following application. In hot, windy conditions, apply in the early morning or at night. It may be necessary to spray water on hot concrete to cool the surface prior to application so PENTRA-HARD® DENSIFIER does not flash-dry on the surface. Clean surface to remove any dirt, laitance, curing compounds or coatings that may prevent PENTRA- HARD® DENSIFIER from penetrating the surface.
When the Citrus Cleaner J48 or similar product is used to strip/clean the floor prior to the PENTRA- HARD application be certain to thoroughly rinse all residue of the stripper from the floor. Do not use high pressure sprayers as they may over atomize the material. Do not allow PENTRA-HARD® DENSIFIER to come into contact with glass, fabric, metal, or painted surfaces. Immediately wipe contaminated surfaces with a damp cloth, then wipe dry with a second clean cloth.
Mixing:
Mildly agitate before each use. Do not thin or dilute.
Placement:
Using an high volume, low pressure sprayer, or a good pump up sprayer for smaller jobs, spray PENTRA-HARD Densifier evenly on the surface. Spread out pools with a soft bristle broom or a flat microfiber pad. If areas begin to dry before 20 minutes (edges, high spots), spray on more material. Surface is ready for use when dry, but the complete reaction may take up to two weeks to develop depending on site temperature and conditions. If concrete is dyed, acid stained, or integrally colored, it may be advisable to clean with scrubbing equipment once the application is complete to produce a more even finish. To enhance the color intensity, gloss and light reflectance, and to reduce efflorescence, mineral deposits and staining use Pentra-Hard Guard, Stain and Wear Protector in conjunction with Pentra-Hard Densifier as a post-applied topical treatment.
On newly placed concrete, PENTRA-HARD Densifier may be applied immediately after the finishing, or immediately after joints have been cut and cleaned, or anytime thereafter, at the project manager’s discretion. Dayton Superior approved membrane forming curing materials or bond breakers may be applied over the top of PENTRA- HARD Densifier once it is no longer wet on the surface. Contact Dayton Superior for recommendations.
In cool, humid, or enclosed conditions, PENTRA- HARD Densifier may stay wet for an extended period. After 1 hour of dwell time, rinse the surface and pick up excess material.
Maintenance
Clean up spills promptly. Regular aggressive scrubbing with neutral cleaners is recommended. DO NOT USE acidic cleaners to maintain the floor.
PENTRA-HARD® Densifier
Lithium Concrete Hardener, Dustproofer, Sealer
Clean Up
Use soap and water to clean tools and equipment. Although Pentra-Hard Densifier is non-toxic and environmentally safe, it is alkali—use up or dry out extra material and dispose of according to local regulations. Don’t pour into sewer systems or storm drains.
