  • Liquid Silicate densifier hardner concrete glossy durable harder water resistant


Liquid Silicate makes concrete more durable, harder, water resistant.
Concrete densifier, hardner formulated with penetrating lithium silicate that reacts and forms an extremely strong bond with pores / capillaries in concrete. Treated concrete is more dense, harder, more durable, extra water resistant, extending the concrete life with less maintenance. Treated concrete can be custom designed, colored and polished resulting in a glossy, aesthetically pleasing yet durable, dust free, mar free, tough decorative concrete.

Priced by the gallon. Packaged in 5 or 55 gallon containers.

USSC's LIQUID QUARTZ is specially formulated with highly reactive and concentrated Lithium Silicate along with colloidal silica to be applied on poured concrete that is still wet or can be used on concrete slab that is years old. This unique product has an abundance of reactive sites that go to work within a few minutes. Spray it on concrete until the surface is saturated and stops soaking up the liquid. There is no need to work the applied product or cleaning or brooming up of the excess material. Special additives in the formulation are designed to penetrates and efficiently react with the concrete. One hour of dry time is recommended before diamond polishing is done. Product is safe, has low pH, green, environmentally and user friendly, non hazardous, very low odor, very low VOC's and no hazardous material disposal needed. It is shipped as a concentrate. One gallon will make five gallons of usable product. Saves on shipping costs, storage space, net material costs. 

  • Nano particle size, special additives and high concentration of reactive sites makes LIQUID QUARTZ work faster.
  • Can be applied to broom finished, steel trowelled, power trowelled or burnished concrete surfaces.
  • Penetrates pores, capillaries and reacts with concrete to form strong calcium lithium silicates.
  • Good, dense bonding structure produces excellent initial strength and then ultimate hardness.
  • Produces a surface gloss which reduces dust production and reduces maintenance efforts and costs.
  • Improves gloss, performance, appearance and light reflectance of new or old concrete.
  • Reduces application time and costs of diamond polishing of concrete surfaces.
  • When treated properly concrete surface is breathable and will not yellow, discolor, peel or flake.
  • VOC compliant, Non-flammable, Non toxic, Non hazardous, Low odor, environment and user friendly.
  • Cures fast in 30 - 60 mins. Most projects can be open to traffic in an hour after treatment.
  • Formulated and MADE IN THE USA.

Technical Data Sheet USSC lithium concrete DENSIFIER-LIQUID QUARTZ

USSC's concrete densifier is a special formulation of penetrating lithium silicates that reacts with concrete to produce
insoluble calcium silicate hydrate within the concrete pores. Treated surfaces are more resist to water
damage and surface abrasion and also reduced dusting with less maintenance. USSC Densifier will not
contribute to surface ASR ( Alkali Silicate Reaction ).


• May be applied to broom finished, steel trowelled, power trowelled or burnished concrete finishes.
• Penetrates and reacts quickly to produce better initial and ultimate hardness.
• Produces a fast surface gloss which improves with traffic and maintenance.
• Improves performance, appearance and light reflectance of new or old concrete.
• Reduces application time and costs of diamond polishing operations.
• Will not contribute to surface crazing. High lithium content combats surface ASR.
• Lithium will not absorb water or contribute to floor sweating.
• Breathable and UV stable. Will not yellow, discolor, peel or flake.
• VOC Compliant. Non flammable. Non toxic. Low odor.
• Cures quickly. Most floors can be opened to traffic within one hour of treatment.

Physical Data

FORM : clear, water-like liquid.
pH : 11.0
WT/GAL : 9.2 lbs
VOC CONTENT : < 20 g/L
SHELF LIFE : 2 years in unopened, factory-sealed container.


Protect people, vehicles, property, plants and all surfaces from the product, splash and wind drift. Use polyethylene or other proven protective material. May be applied to freshly placed concrete after final
finishing and installation of the control joints. USSC Densifier is ideal for application to existing, cured
concrete of any age. Surfaces must be clean and structurally sound. Remove all foreign materials including
bond breakers, curing agents, surface grease and oil, and construction debris. Application may begin as
soon as prepared surfaces are dry and free of pooled water. Do not apply to surfaces that are frozen, dirty or
have standing water.
Surface & Air Temperatures : Temperatures for application should be 40-100°F (4-38°C).
Equipment : Apply with low-pressure sprayer, mop or a soft-bristled push broom.
Storage & Handling : Store in a cool, dry place. Always seal container after dispensing. Do not alter or mix with other chemicals.
Published shelf life assumes upright storage of factory-sealed containers in a dry place. Maintain
temperatures of 40-100°F (4-38°C). Keep from freezing. Do not double stack pallets. Dispose of in
accordance with local, state and federal regulations.


TEST using the equipment and procedures selected for general application. Follow the application
instructions below to pre-test each slab. Pretesting will confirm the suitability of the surface preparation
and application procedures proposed for general application. Pre-testing will also determine the average
coverage rates to be maintained over the entire project. Let surfaces dry thoroughly before inspection and
approval. Surfaces to be treated must be clean, dry and absorbent. Confirm surface absorbency with a light
water spray – surfaces designated for treatment should wet uniformly. Do not dilute or alter.

Typical Coverage Rates : Variations in concrete quality, porosity, job site conditions, temperature and relative humidity will affect coverage rates and drying times.

Typical coverage rates are as follows:-

Freshly Placed, Uncured, Steel Troweled Concrete

  • 600–800 square feet per US gallon
  • 56–93 square meters per US gallon
  • 15–25 square meters per liter

Cured, Steel Troweled Concrete

  • 500–700 square feet per US gallon
  • 46–83 square meters per US gallon
  • 12–22 square meters per liter

Cured, Ground/Honed Concrete

  • 400–500 square feet per US gallon
  • 37–74 square meters per US gallon
  • 10–20 square meters per liter
