Lythic™ 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, Lythic™ Densifier’s unique formulation of uniform,
concentrated, Nano sized particles, suspended in an ultra low surface tension
liquid, penetrates deeply into concrete surfaces bonding with the cement
components of the slab. Lythic™ Densifier makes an extremely hard, dense floor
surface that has increased wear resistance to foot and fork lift traffic. It is
water based and environmentally friendly and is VOC compliant in all states.

How
It Works
- Colloidal silica works by reacting with lime in concrete. During hydration, approximately 20 % of a concrete mixture's Portland cement is converted to lime, which has no structural value in concrete.
- However, colloidal silica pozzolanically reacts with lime to form CSH strengthening crystals.
- Concrete also contains naturally occurring silica. Because silica bonds best to itself (a property not found in any silicate densifier) colloidal silica is able to build up more density and strength in a concrete surface.
- It can be applied to new, hard-trowelled floors, or to existing slabs.
Direction
Lythic™ Densifier
has two primary methods of application. The first method is designed for
application while the slab is still green just after final trowel. The second
is designed for use with existing or cured concrete.
New
Concrete (Green)
Lythic™ Densifier
may be applied to newly installed concrete after final trowel while slab is
still Green. Slab must be clean and free of all materials such as curing
compounds, bond breakers, form release oils or construction dust and debris,
etc. Use a low pressure sprayer to achieve a consistent, even application and
to ensure consistent coverage of the surface. Reapply as necessary to keep
surface wet for 20 minutes. Let surface dry. No cleaning, flooding,
neutralizing or rinsing is necessary. If curing agent is to be applied, it can
now be applied over dried application of Lythic™ Densifier.
Existing,
Cured Concrete
Lythic™ Densifier
can be applied to concrete of any age. Surface must be clean and structurally
sound. Surface also must be clear of membrane forming curing compounds,
sealers, oils, dust and other surface contaminates. For best results use a
black scrubbing pad with Lythic™ Cleaner. If more aggressive surface
preparation is needed to remove surface contaminants, 60-100 grit sanding
screens can be used. A thorough cleaning is needed after additional scrubbing
Diamond
grinding/polishing to an 800 grit finish with Lythic™ Densifier, will provide
the most durable and stain resistant floor surface.
Use a low pressure
sprayer to apply Lythic™ Densifier to form an even sheen across surface to
ensure complete saturation of surface. Apply enough Lythic™ Densifier to keep
the surface wet for 15 to 20 minutes. Let surface dry 1 hour before heavy
traffic.

Process
For Lythic HardWear Floor
The Lythic HardWear
Floor is a cost-effective alternative to diamond polishing. The Lythic HardWear
Floor is based on a double treatment of Lythic Reactive Colloidal Silica
densifiers. It can be applied to new, hard-trowelled floors, or to existing
slabs with light grinding. The first treatment, with standard Lythic Densifier,
bonds silica particles of about 5-nanometre size to the concrete. This base
layer forms a bonding surface (or landing pad) for a special version of the
densifier, Lythic XL, with silica particles of about 45-nanometre size. These
larger particles quickly build up density in the surface and may actually fill
in finer scratch patterns. When this newly-made, high-silica surface is
burnished, it produces a near-polished gloss. It eliminates two or three
diamond-polishing passes, saving on the costs of both labour and diamond
tooling. After stain protection, a 100-grit grind can resemble an 800-grit
polish. It has all the performance properties of a polished concrete floor, and
similar low maintenance requirements.
Products
Lythic
Densifer
Lythic™ Densifier’s
unique formulation of uniform, concentrated, Nano sized particles, suspended in
an ultra low surface tension liquid, penetrates deeply into concrete surfaces
bounding with the cement components of the slab. Lythic™ Densifier makes an
extremely hard, dense floor surface that has increased wear resistance to foot
and forklift traffic. It is water based and environment friendly.
XL
Densifer
Lythic™ Densifier
is a colloidal silica based concrete hardener and densifier that 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 fills the
surface capillaries of concrete with silica creating a permanent bond that
makes floor surfaces harder, less prone to dusting & the absorption of most
liquids.
Protector
Lythic™ Protector
is a penetrating concrete sealer formulated to enhance and protect Concrete Polishing floors. It is a
unique product that includes colloidal silica for surface hardness and lithium
for water repellency. It is a water-based, environment friendly product that
enhances coloured concrete floors, and increases durability, as well as slip
resistance.
Cleaner
Lythic™ cleaner is
a non-corrosive cleaner, formulated to remove surface dirt and soil from
concrete floor surfaces. It fortifies concrete surfaces with amorphous silica
as it cleans to increase durability and maintain surface polish.
Maintenance
Routine sweeping,
mopping and periodic mechanical scrubbing with a neutral pH, non-rinsing
cleaner or water is needed. We recommend using Lythic Cleaner for all cleaning
regimes. Avoid any acidic cleaners. Acidic cleaners may etch the surface over
time and cause a dulling of the finish. No aggressive scrubbing brushes such as
straogrit, nylogrit or other aggressive scrubbing brush should be used. Avoid
detergents containing hydroxides or sulfates.
Lythic Densifier Vs Conventional Silicate Densifiers
- Lythic Densifier eliminates the risk of whiting as it contains less than one half of 1 % metallic salts unlike other Silicate densifiers, which may have up to 25% metallic salts, and presents a risk of whiting of surface.
- The self-bonding ability is the driving force in our Lythic Protector & Lythic Cleaner products.
- Each delivers more silica, bonded into the floor, improving the surface with every application and ensuring that each application bonds tightly.
- Reactive Colloidal Silica densifier is far safer to handle than silicates. It has a pH similar to baking soda. Conventional sodium silicate densifiers are far more caustic and produce lye (sodium hydroxide) as a by-product.
- Lythic Products are water based and environment friendly.
- Safer for Workers and Jobsite: It is thousand times less caustic than silicates.
- Speeds up project: No, scrubbing in, no overnight curing, no scrub off.
- Safer for Environment: No caustic residue to scrub off and dispose of as a hazardous material. Shipped as on centrate to reduce transportation impacts.
- Works well on overlays too: Bonds directly to silica in the overlay cement, making it stronger and more polishable.
- Cost-Effective: Cuts steps, reduces labour, high coverage rate,
- Shipped as concentrate to save shipping costs.

Frequently Asked Questions about Concrete Densifiers
What
is Concrete?
Concrete is a
mixture of portland cement, aggregate (sand and rock), water and additional
ingredients called admixtures. A chemical reaction called hydration causes the
cement and water to harden and bind the aggregates.
How
do Densifiers Work?
Densifiers, also
known as “hardeners,” contain special silica-based chemicals. When applied to a
concrete surface, the silica reacts with lime and produces additional CSH. The
new CSH crystals permanently bond, filling the microscopic concrete pores to
decrease porosity, reduce “dusting,” and create a denser and harder concrete
surface.
Is
there a Difference in Densifiers?
Yes! Until
recently, all densifiers used alkali-metal compounds called “silicates” – such
as sodium silicate, potassium silicate, or lithium silicate. Silicates are old
technology. They work, but have many drawbacks that must be dealt with by the
contractor and building owner. A new type of densifier chemistry, colloidal
silica, overcomes these drawbacks. How is concrete formed? Hydration produces
calcium-silicate- hydrate (CSH). CSH crystals are the glue that holds concrete
together. A by-product of this reaction is calcium hydroxide (lime). Lime is
water-soluble and the weakest part of concrete. Hydration continues throughout
the life of a slab producing lime that causes “dusting” on the concrete.
What
is Densifying?
As excess water in
a mix evaporates, it leaves a network of tiny voids called pores. Densification fills these pores with additional
cementitious crystals. This hardens the surface, makes it more resistant to staining,
and reduces dusting of the concrete surface. It is an important step in
creating decorative polished concrete finishes and is increasingly being used
on ordinary concrete floors to make hard wear surfaces that are
more durable and easier to maintain.
How
is Lythic Densifier Different?
Regardless of the
type of densifier, only the silica reacts with lime to create CSH. The question
is, how to get silica into the concrete, and Lythic™ Densifier is the most effi
cient means. That’s because the sodium or potassium in other densifi ers form
compounds that actually impede silica’s reaction with lime. Lythic™ Densifier,
on the other hand, contains colloidal silica – nearly pure silica in a water solution – so it
reacts quickly, cleanly, and completely. And colloidal silica particles are
nano-sized to penetrate all but the smallest pores in concrete for maximum densification
& Dust Proofing.
What
are other benefits of Lythic™ Densifier?
Lythic™ is
available as a concentrate to reduce shipping and storage costs. It contains
zero VOCs, can be used in occupied buildings, and is compatible with concrete
dyes.
