Concrete densifiers are also known as chemical hardeners. When applied to a concrete floor, a densifier fills empty spaces in the material and oftentimes forms a chemical bond with the concrete, changing its properties and increasing surface density.
Benefits of Using Densifiers
Densifiers are used specifically to improve the concrete surface when polishing. As long as free lime is present, the complete saturation of a densifier will make substrate harder, which allows a more aesthetically pleasing finish grinding and polishing, and prolongs the durability of the polish. Other benefits include:
- Reduced dusting
- Higher, deeper gloss than untreated concrete
- Increased abrasion resistance and weathering
- Longer floor lifespan
- Locks in a topical color application
- Stain resistance
- Easier to clean
Types of Densifiers
Different types of densifiers create a chemical bond with concrete in a variety of ways. Runyon Surface Prep carries a wide selection of densifiers; below is a comparison of the three most popular.
Ameripolish – 3D Hybrid Silicate Densifier
- Developed to help keep concrete looking newer longer
- Improves performance of new, old or aged and existing concrete
- Can be used with integrally-colored cements
- Contains UV stabilizers to help protect color from fading
- Penetrates fast for a deep seal
- Hardens deep to improve durability even after grinding
Convergent – Pentra-Sil Densifier
- Developed to increase the integrity and life of concrete floors
- Patented nano lithium hardener technology reacts with the concrete to produce calcium silicate hydrate (CSH), creating a strong, virtually impenetrable and durable finish with only one-coat and no rinsing
- Resistant to bacteria
Prosoco – Consolideck LS
- Developed to improve the appearance and performance of architectural masonry
- Gives new life to historic buildings, monuments, existing buildings, new masonry and reinforced concrete structures
- Lithium silicate treatment reacts with the concrete to produce CSH
- Safer, faster and easier to apply than conventional sodium or potassium silicate hardeners
- Will not trigger or contribute to surface ASR (Alkali Silicate Reaction)
- Resists damage from water
