You’re in the right place if you’re looking for the most popular concrete densifiers.
In this guide, we’ll demystify the different types of densifiers and explain when and how to use them. We’ll also compare densifiers to sealers and provide you with some helpful tips for optimizing your concrete surfaces.
Concrete Densifiers vs. Sealers
You use concrete densifiers to harden and strengthen the concrete by filling in the pores and reacting with the calcium hydroxide in the concrete. This process creates a denser and more durable surface resistant to abrasion, dusting, and other forms of wear and tear.
On the other hand, you use sealers to protect the concrete from external elements such as water, oil, and chemicals. They form a protective layer on top of the concrete surface, preventing moisture penetration and staining.
When to Apply Concrete Densifier
Typically, densifiers are applied after the concrete has been cured for at least 28 days. This allows the concrete to mature fully and ensures the densifier can penetrate deeply into the surface.
Densifiers are also commonly used to harden and strengthen new concrete surfaces and rejuvenate old and worn-out surfaces. If you notice that your concrete shows signs of wear and tear, such as dusting, spalling, or cracking, it may be time to apply a densifier.
3 of the Most Popular Densifiers and Their Brands
Different types of densifiers create a chemical bond with concrete in a variety of ways. Runyon Surface Prep carries a wide selection of densifiers, including some of the most popular options on the market. Here’s a comparison of three of our top-selling products:
- Ameripolish 3D Hybrid Silicate Densifier: This densifier helps keep concrete looking newer longer and improve the performance of both new and old concrete surfaces.
It can even be used with integrally-colored cements and contains UV stabilizers to protect color from fading. The Ameripolish 3D Hybrid Silicate Densifier penetrates fast for a deep seal and hardens deep to improve durability even after grinding. - Convergent Pentra-Sil Densifier: This densifier increases the integrity and life of concrete floors. Its patented nano lithium hardener technology reacts with the concrete to produce calcium silicate hydrate (CSH). It creates a strong, virtually impenetrable, durable finish with only one coat and no rinsing.
The Convergent Pentra-Sil Densifier is also resistant to bacteria. - Prosoco Consolideck LS: This densifier improves the appearance and performance of architectural masonry. It gives new life to historic buildings, monuments, existing buildings, new masonry, and reinforced concrete structures.
The lithium silicate treatment reacts with the concrete to produce CSH and is safer, faster, and easier to apply than conventional sodium or potassium silicate hardeners. The Prosoco Consolideck LS will not trigger or contribute to surface ASR (Alkali Silicate Reaction) and resists damage from water.
When choosing a densifier, it’s essential to consider the specific needs of your concrete surface and its environment. Consult with the experts at Runyon Surface Prep or read the manufacturer’s instructions to determine the best type of densifier for your project.
Concrete Densifier Tips
In addition to using the best densifier for your project, there are other ways to optimize your concrete surfaces.
Here are some tips:
- Clean and prepare the surface before applying the densifier. This will ensure that the densifier can penetrate deeply into the surface and create a strong bond.
- Use a sprayer or roller to apply the densifier evenly. Make sure to follow the manufacturer’s instructions for application and drying time.
- Consider adding color or decorative elements to your concrete surface. This can be done by adding pigments or stains to the densifier or by using decorative concrete techniques such as stamping or polishing.
By following these tips and using the best concrete densifiers for your project, you can create a durable and beautiful concrete surface that will last for years to come.
