Flor Sil

Hardener / Densifier For Concrete & Terrazzo

For use In the Grinding, Polishing and Repolishing Process. (Metal / Resin-bonded Abrasives) of Concrete and Terrazzo Surfaces.

Best for ULTRAFLOR® Polishing, or Repolishing and Restoring Worn or Damaged Surfaces.


FLOR-SIL is a concrete and terrazzo densifier formulated with the latest hybrid lithium chemical technology. Used in the Diamatic Management Services (DMS) ULTRAFLOR®System. FLOR-SIL penetrates deep into concrete surfaces, providing longer life and higher reflectivity to the polished concrete surface. FLOR-SIL is an environmentally friendly treatment crucial to the installation of the ULTRAFLOR® System. Together, FLOR-SIL and ULTRAFLOR® produce a concrete/terrazzo surface with improved abrasion resistance and reduced surface dusting. With proper installation, FLOR-SIL™ will not leave clouding effects that can be difficult to remove. Flor-Sil is an easy to apply product that requires only one treatment with no need for brooming or rinsing—a common procedure in sodium and potassium based densifier products. FLOR-SIL will not contribute to alkali-silica reactivity (ASR). FLOR-SIL inhibits alkali salts (efflorescence) and sweating in concrete/masonry surfaces.

FLOR-SIL and the ULTRAFLOR® System extends the life of the concrete far in excess of the traditional polishing process, while enhancing the appearance of the surface. Ultimately, this results in superior durability, exceptional shine retention, and lower life-cycle costs in comparison to all floor coating/covering systems.


400 to 500 sq. ft. per gallon (12-15m2 per liter). Note: Coverage or treatment yield will vary with concrete quality, porosity, finish, and environment.
