The Best Concrete Floor Densifiers for Professional Surface Restoration

Concrete surfaces, especially flooring tend to withstand immense pressure from high levels of foot traffic, wear and tear, impactful machinery, and chemical spills. Although it is ideal for heavy-duty environments, this material does not last forever so concrete floors may lose surface strength and density. However, its longevity is solely dependent on how it is cleaned and maintained in the long run. Through the use of concrete densifiers is the absolute best solution to prevent premature degradation of concrete floors.

This article discusses which products are considered the best concrete floor densifiers/ hardeners for professional surface restoration.

Why do Concrete Densifiers Flourish in the Concrete Flooring Industry?

Concrete densifiers are also referred to as “concrete hardeners” and are composed of materials that preserve and strengthen concrete floors following a thorough process of curing and sealing. ​Concrete densifiers specify as an advanced chemical hardener that is applied on top of concrete floor surfaces. This action in turn fills the concrete pores to yield a harder, stronger density throughout the applied surface area, ultimately improving the integrity of the concrete floor.

Concrete densifiers/ hardeners are typically utilized during the process of concrete floor polishing to assist with surface refinement. Whether the concrete floor is polished or not, densifiers can dramatically accelerate its lifespan, strength, and overall performance. These concrete floor hardeners act as a shield of armor to protect the concrete, by increasing surface durability and creating an effective surface resistance to damages from continual wear-and-tear.

Hardeners can also prevent freshly poured concrete from curling. Curling refers to the distortion of a slab into a curved shape after its edges bend in an upward and downward manner. Therefore, concrete densifiers/ hardeners can work on either existing concrete floors or newly applied slabs.

What is considered the BEST Concrete Densifiers/ Hardeners for Professional Surface Restoration?

More often than not, the flooring industry uses the terms ‘hardener‘ and ‘densifier’ interchangeably. Hardener emphasizes strengthening properties while densifier focuses on minimizing the surface porosity. In other words, concrete densifiers/ hardeners emphasize making concrete slabs harder and more resistant against abrasive components. This process will raise the mass per volume of the concrete slab to completely fill in the cracks and make the surface smoother.

In the field of concrete surface restoration, there are only a few principal types of concrete floor densifiers/ hardeners that offer legitimate unparalleled strength, maximum durability, and superior performance:

#1. The Most Cost-Effective, Eco-Friendly, and Deeply Penetrating Concrete Floor Densifying & Hardening Agent in the Market!

Xtreme Hard Concrete Densifier yields an extremely hard and dense concrete floor surface that has increased wear resistance to foot and forklift traffic. Xtreme Hard Concrete Densifier is a green, clean, and safe material. Its low PH formula (approx 8.7) is safer for you to handle and emits no volatile organic compounds (VOCs) and eliminates hazardous material disposal, so it’s better for the job site and friendlier to the planet. This product is water-based and environmentally friendly and is VOC compliant in all states.

How does it work?

Xtreme Hard Concrete Densifier is a blend of inorganic polymer materials that penetrates slab concrete to increase surface density and hardness. Utilizing a proprietary and “green” manufacturing process, Xtreme Hard Densifier has a unique formulation of concentrated uniformity and nano-sized particles that are suspended in an ultra-low surface tension liquid to penetrate deep into a concrete surface and bonding with the cement components of the slab.

Because it is a highly reactive colloidal silica-based densifying agent, the Colloidal Silica molecule has more reactive sites, so it goes to work quickly (1-2 mins). Spray it on the concrete until the surface is saturated, then agitate with a soft bristle broom. Wait until dry (45-60 mins). New and improved Nanotechnology formula penetrates deeper into the concrete.

What are the Advantages of Xtreme Hard Densifier?

There is a multitude of benefits when using Xtreme Hard Densifier on your concrete floors, like how it reduces operating costs by increasing the ease of constant cleaning and maintenance. However, there are a few fundamental advantages that this product delivers:


Concrete floors that are treated with Xtreme Hard Densifier require little to no maintenance for a very long time. Unlike the traditional line of concrete floor densifiers, its application is resistant to dust and abrasion. Being low maintenance is highly beneficial for commercial uses where high foot traffic is inevitable.


Xtreme Hard does not consist of chemicals that can be hazardous to the health. There are also no issues with fumes during application, considering that this chemical is liquid-based. Occupants and businesses can go back to normal as soon as the concrete floor dries up.


Besides also being the lowest cost concrete densifier in the market, Xtreme Hard Concrete Densifier is also versatile in its availability for the different choices of size:

  • Xtreme Hard Densifier – 32 Ounces
  • Xtreme Hard Densifier – 1 Gallon
  • Xtreme Hard Densifier – 5 Gallons
  • Xtreme Hard Densifier – 55 Gallons

#2. Improving Concrete Surface Hardness, Polishability, and Stain Resistance!

SCOFIELD® Formula One ™ Lithium Densifier MP gives you a more cost-effective way to provide longer life to the colored architectural ground and polished concrete floors in schools, hospitals, government buildings, retail stores, shopping centers, and restaurants. It contains the optimal solids content required to deliver the best penetration and reactivity: a higher-solids-content formulation that is designed to be diluted 1:1 with potable water.

This concentrated formula means you get TWICE the usable densifier in every container. For softer or more porous concrete SCOFIELD® Formula One ™ Lithium Densifier MP can be used full strength. SCOFIELD® Formula One ™ Lithium Densifier MP is typically used for all concrete floor applications that are assigned an architectural value. It reacts well with the concrete surface, reducing porosity and dusting, improving abrasion resistance and overall long-term durability. This product contains no VOCs.

#3. Low Solids, Hybrid Silicate Concrete Floor Densifier and Hardener!

Ameripolish 3D HSL (3 densifiers in one product) Hybrid Silicate Densifier is formulated with 3 different size molecule silicates to penetrate even the most difficult, tight floor cap. 3D HSL strengthens and densifies from within the concrete by providing strength at multiple levels of the slab and is ideal for use for exposed and polished concrete, as well as integrally colored cement.

Ameripolish 3D HSL improves surface performance and resists the harmful effects of traffic wear and weathering by improving the abrasion resistance for new or aged concrete. 3D HSL can be used on new or old concrete, polished or exposed concrete, and even concrete with integral concrete coloring. Formulated with UV stabilizers, this formula enhances polished concrete finish, visibility and it also helps prevent color fading over time.


Surface restoration experts utilize concrete floor hardeners/densifiers to fill and strengthen the pores of concrete slabs, making them harder and resistant to dust and abrasion. It generates a chemical reaction that indicates that the concrete gets sealed permanently. Newly poured concrete slabs should harden for about 28 days before implementing any type of liquid concrete densifier agent on top. Now it is time for you to eliminate the susceptibility of concrete floors to damages caused by abrasive elements, heavy impact, and scraping and accelerate the lifespan of traditional concrete floors!
