  • Silicate to harden diamond polish concrete plus water repeller sealer


Silicate to harden diamond polish concrete plus water repelling sealer.
Concrete densifier, hardner specifically formulated with penetrating lithium silicate that reacts and forms an extremely strong bond with pores / capillaries in concrete. This formulation has a special water repellent that incorporates additional water resistant and protective properties. Treated concrete is more dense, harder, more durable, extra abrasion resistant, more resistant to water, resists freeze-thaw cycles. Protects, extends the life of concrete with less maintenance.

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

LIQUID QUARTZ plus REPELLENT specially formulation with highly reactive and concentrated Lithium Silicate along with colloidal silica and a special water repelling agent can be applied on poured concrete that is still wet or on a concrete slab that is years old. Has all the performance and advantages of LIQUID QUARTZ plus enhanced water repellent properties. Spray it on concrete until the surface is saturated and stops soaking up the liquid. Can be applied on brand new concrete. Best time to apply is after final finishing is done. This product will hold the hydrates in allowing proper and complete hydration of the cement. No need to wait 28 days to protect concrete it is protected immediately. There is no need to work the applied product or cleaning or brooming up of the excess material. One hour of dry time is recommended. 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.

  • Special additive imparts water repellency, enhances surface traction, more crack resistant, resists freeze thaw damage.
  • 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.
  • High Lithium content will not contribute to alkali silicate reaction.
  • When treated properly concrete surface is breathable, mildew resistant and will not yellow, discolor, peel or flake.
  • VOC compliant, Non flammable, Non toxic, non hazardous, Low odor, environmentally 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's lithium concrete DENSIFIER-LIQUID QUARTZ with water repellent sealer

USSC's concrete Densifier is a formulation of penetrating lithium silicates that reacts with concrete to produce
insoluble calcium silicate hydrate within the concrete pores.

Addition of the special water repellents increases the treated surfaces performance to be more resistant 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
  • Added water repellent enhances the ability of the concrete to resist water damage and stains.
  • 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 : milky, water like viscosity 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
