DENSIFIERS

The Difference in Densifiers

Densifiers add silica to the surface of concrete to increase surface hardness for abrasion resistance and better polishing, and to make it less permeable to liquids. Lythic Densifier with Reactive Colloidal Silica is 99.5% pure silica, suspended by charge repulsion in an ultra-low surface tension liquid by a proprietary, “green” manufacturing process. Nano-sized silica particles – approx 5 nm – penetrate pores deeply. They react highly effectively with the lime in concrete, and bond to silica already in the slab. Reactive Colloidal Silica even bonds to decorative cementitious overlays that are low-lime and do not react with silicate densifiers.

Lythic Densifier is fast, safe, and environmentally friendly. It cuts steps on the job, bringing down cost. It improves the response of concrete and cementitious overlays to operations like diamond-polishing or burnishing. Lythic Densifier is part of a system of advanced Reactive Colloidal Silica chemistry that establishes and maintains exposed concrete using on-going silica enhancement that becomes part of the floor structure.

Lythic Densifier vs. Silicate Densifiers

Safer for Concrete: Unlike silicates, there are no excess mineral salts in Lythic Densifier to discolor the concrete. Unlike lithium silicate, it cannot result in “whiting” even if over-applied.
More effective: Reactive Colloidal Silica has more reactive sites on the molecule than silicates, and therefore forms chemical bonds more readily. It fills the pore structure more consistently, and can even “rescue” soft or damaged concrete.
Safer for Workers and Jobsite: It is 100X-1000X times less caustic than silicates, making it safer for workers to handle and safer to use near other finished surfaces.
Speeds up project: Unlike sodium- or potassium-silicate, there is no overnight curing required.
Safer for Environment: It is more environmentally friendly. Unlike sodium- or potassium-silicate, there is no caustic residue to scrub off and dispose of as a hazardous material.
Works Well on Overlays, too: Unlike silicates, Lythic Densifier will densify cementitious overlays that do not contain sufficient lime for silicate reaction. Reactive Colloidal Silica bonds directly to silica in the overlay cement and in its silica-sand aggregate. It makes overlays stronger and more polishable.

New Finish Options with Lythic Densifier

Lythic Densifier’s unique properties make possible a new, high-appearance, low-cost flooring process, the HardWear Floor. Using two different particle-sizes of Reactive Colloidal Silica, it creates a near-polished looking floor with all the performance advantages of polished concrete, but without the expense and time of diamond-polishing.

XL Densifier

XL Densifier prevents dusting and increases durability in concrete floors. Engineered with a specifically sized silica particle, it is designed to strengthen soft porous concrete slabs. Floors treated with Lythic XL Densifier are durable and resistant to dusting and wear.

It is effective in restoring worn and damaged concrete, rehabilitating them and making it possible to effectively polish them.The larger silica molecule in Lythic XL Densifier is ideal for restoring the surface of old concrete slabs that have softened and lost surface strength. XL Densifier makes it possible to generate the HardWear Floor process for durable and reflective concrete floors.
