Concrete Densifiers help seal masonry, concrete, and other Portland cement based materials into a mass that is solid, rather than porous. Its penetrating quality provides deep sealing that is effective for the life of the concrete. This creates a floor surface that will be easy to clean and maintain. Concrete densifier’s chemical densifying action hardens and strengthens within the concrete mass, protecting against deterioration. This densifying action produces a floor that is resistant to traffic. Rather than eroding, the floor surface actually self polishes.
What is a Densifier and Why is it Important?
With the development of polished concrete there have been a number of new products introduced to assist contractors with the polishing process. The most significant development in concrete polishing has been the introduction of concrete densifiers. There are a large number of concrete densifiers available on the market today.
There are three different types of densifiers on the market with regard to the chemical composition; Sodium silicate, lithium silicate, and potassium silicate are the different compounds available. The densifier is applied to the floor to create a denser surface structure and increase the longevity of the polish on the floor. The primary way in which they do this is by increasing the abrasion resistance of the floor making the surface less susceptible to scratching, scuffing, and dusting. Dusting is the process of the concrete surface deteriorating and creating fine dust particles on the surface as it wears. This is the most common and most
detrimental issue with polished concrete in that it wears the polished surface away and exposes the unpolished surface below. The primary purpose for applying a densifier to a polished concrete surface is to prevent this from occurring.
