Euclid UltraSil Li+ Concrete Densifier, Sealer & Dustproofer – 5 Gallon Pail

Improve the durability and performance of concrete floors with ULTRASIL Li+.

ULTRASIL Li+ is a water-based lithium silicate concrete densifier, sealer, and dustproofer designed for interior concrete floors. The treatment penetrates the concrete surface and chemically reacts within the pores to produce a hard and dense calcium silicate hydrate (CSH) structure.

Unlike traditional surface coatings, the treatment becomes an integral part of the concrete. This means it does not peel or flake, remains unaffected by moisture, and provides long-lasting protection.

ULTRASIL Li+ is especially well suited for polished concrete and high-traffic commercial or industrial floors, helping create surfaces that are denser, more durable, easier to clean, and more resistant to water and mild chemical damage.

• Densifies, seals, and dustproofs concrete in one application
• Water-based formulation with low VOC
• Penetrates the concrete surface rather than forming a conventional film
• Creates a hard, dense concrete surface
• Helps improve concrete durability
• Provides permanent treatment that will not peel or flake
• Helps make concrete floors easier to clean and maintain
• Improves resistance to water and mild chemicals
• Suitable for diamond-polished concrete
• Can contribute to LEED points
• Suitable for commercial, industrial, institutional, and healthcare environment
