Concrete densifier is often promoted as one of the top advancements in concrete technology today. However, the nature of the product can be confusing to those without a deep knowledge of the concrete industry. What is densifier? How does it work? How might it affect the life of your flooring?
Here is a brief FAQ regarding these questions and more.
What Is Concrete Densifier?
Concrete densifier is a chemical product applied to the surface of a concrete floor to provide more density to the concrete. Once applied, the densifier fills in the pores near the surface of the concrete, providing a denser product and a harder surface. Building owners utilize concrete densifiers to produce a finish that is more resistant to wear and staining.
What Is Concrete Densifier Made Of?
Although chemical components may differ slightly across brands, most concrete densifiers are similarly composed. Typically, densifiers are water-based and made up of chemicals that react with the concrete to fill its pores. Most often, these chemicals include sodium, potassium, or lithium silicates.

How Does It Work?
As concrete cures, it produces calcium carbonate as a byproduct – also known as free lime or concrete dust. After concrete densifier is applied, its chemicals react with this concrete dust to form a calcium silicate hydrate gel. The gel fills the pores near the surface of the concrete, eventually crystallizing and tightening the pores to provide more density and hardness to the concrete.
When Is It Applied?
Concrete densifier can be applied to multiple types of newly placed concrete floors, including high traffic areas like loading docks and warehouses, as well as large, flat areas for commercial spaces that will eventually receive polish. In fact, polished floors should always receive a densifier treatment during the refinement process to increase resistance to staining, abrasion, and dusting. The stage in the refinement process at which the densifier is applied can vary based on the nature of the concrete used and may occur after the initial metal grinding or as a final step.

Why Should You Use Densifier?
Densifier does not replace sealers or epoxy coatings, both of which provide a truly sealed surface that repels stains. In addition, epoxy provides an additional layer of protection, which absorbs some of the wear and tear normally experienced by the concrete. However, for natural or polished concrete floors, densifiers provide oil and chemical resistance, minimal dusting, and increased durability against abrasion and other forms of wear.

Concrete is a porous material, and despite its strength and durability, this means it’s vulnerable to certain weather conditions. Winter weather – especially snow – can wear down concrete surfaces by seeping into the material. Much like roads and sidewalks, concrete patio floors and driveways can experience destructive freeze/thaw cycles during the winter. As a homeowner, it’s important to understand why the winter poses such a big threat to concrete surfaces and how you can act to protect your concrete during the coldest months of the year.
One of the perks of installing polished concrete floors in your home, garage, or patio is its low maintenance. Concrete is strong and durable, and part of the charm is in its imperfections. Without a bit of regular floor maintenance and care, however, you risk exposing your concrete floors to the elements. Concrete is porous and can absorb stains that may blemish your space.
