Product Description

1, PRODUCT DESCRIPTION
The lithium silicate formulation of Harden 510 creates greater density by reacting with the calcium hydroxide in the concrete to form stable, insoluble tri--calcium silica structures. This superior densification process ensures maximum resistance to dusting, abrasion, bacteria, and chemical attack.
Harden 510 Is sprayed evenly over the area to be treated--there is no need to flush the surface or remove and dispose of any excess material after installation. Treated Surfaces not only maintain their sheen against traffic and wear, but over time increases from a satin to glossy finish with regular maintenance. The most durable product of its kind, Harden 510 Gives long--term protection in a single application, dramatically reducing maintenance costs and facility downtime.

USE
Harden 510 Is designed for interior or exterior use on new or existing concrete, Including tilt--‐up construction slabs. Its many industrial and commercial applications include warehouses, manufacturing facilities, food processing plants, parking garages, distribution centers, retail stores, hospitals, sports & Entertainment venues, convention centers, office complexes, cafeterias, showrooms, transportation terminals, schools, and correctional facilities.

ADVANTAGES
Lithium Technology-allows deeper penetration and a more complete chemical reaction for maximum sealing/hardening/densification
Maximum Resistance To dusting & abrasion
No Flushing-material is simply sprayed evenly over the surface with no flushing or removal of excess material
Durable-one-time installation provides long-lasting protection
Fast-Drying-dries in 10 minutes, open to traffic in 30 minutes
Light-Reflective-provides immediate sheen that improves over time with normal wear and maintenance
Lower Potential for Efflorescence than sodium-based treatments
Stable In All Environmental Conditions-eliminates expansion/contraction caused by ASR in sodium silicates
Low-Maintenance Surface-minimal downtime and maintenance costs
Environmentally Safe-low VOCs(<50g/L), odorless
