industrial coatings and polished concrete flooring systems

Polished Concrete Flooring

Polished concrete flooring is one of the hottest trends for homeowners and business owners alike. Thanks to recent advancements in equipment and technology, the process of polishing concrete is more efficient and economical than ever. Concrete surfaces, both old and new, can be polished to a high-luster finish. When compared to other types of flooring: marble, tile, linoleum, wood and coated concrete, polished concrete is more durable and better performing. Polished concrete never needs waxing and is therefore low maintenance as well.

Aesthetically pleasing, polished concrete flooring has a striking high-luster appearance. The exposure of aggregate in the substrate reveals beautiful textures and natural looking patterns. It can also be stained or colorized in some other way to achieve a one-of-a-kind look that resembles natural stone.

One of the keys to achieving a beautiful high-luster polished concrete floor is to obtain a less porous concrete substrate. This is the job of a product known as a concrete densifier or colloidal silica densifier. Concrete densifiers have been around for nearly 100 years and are specifically designed for this task.

Modern concrete densifiers contain microscopic colloidal silica particles suspended in a low-tension liquid. When the densifier is applied to concrete, it is immediately absorbed into the concrete’s pores. The colloidal silica reacts with the soft calcium in the concrete. This reaction creates a new hard material that is not water-soluble and expands to fills the pores in the concrete. The newly hardened concrete will take a better polish and is more durable providing better abrasion resistance.

Hermetix Densifier is Duraamen’s high performance concrete densifier product. It penetrates more deeply and reacts faster than other brands. Once applied, it starts working in 1-2 minutes. After the application there is nothing to broom off and nothing to dispose of. Hermetix is non-hazardous as well.

To obtain an ultra-high luster, it is recommended that a colloidal silica finishing conditioner is also applied to the finished floor. Hermetix Shield is Duraamen’s protective finishing conditioner that further hardens the polished concrete by adding additional colloidal silica while helping to protect the finished floor with specifically engineered polymers.

Hërmetix densifier | colloidal silica based densifier for polished concrete

Hërmetix is a colloidal silica based densifier for polished concrete systems that transforms ordinary concrete surfaces into exceptionally durable, attractive, colorful floors. Concrete surfaces benefit from the Hërmetix densifier, displaying an attractive floor finish with exceptional durability. It is recommended for concrete floors where beauty, durability and use of environmentally friendly materials are important. Concrete surfaces treated with Hërmetix densifier achieve stunning visual and functional rejuvenation transforming them into colorful and expressive wear surfaces.

typical application areas

  • Big box stores
  • Warehouses / Distribution centers
  • Shopping malls / Retail stores
  • Factory floors
  • Public buildings, schools
  • Government and Private office buildings
  • Residences - Lofts, studios, contemporary living spaces

Densifiers that are used in concrete flooring typically are solutions of silicates that react with the calcium hydroxide is produced during the cement hydration process. Sometimes called liquid hardeners, they impregnate the surface of a cured concrete slab with silica, the basic element of quartz. They essentially complete the hydration process by turning this material into calcium silicate hydrate (CSH), strengthening the concrete mix.

The colloidal silica in Hërmetix is suspended in an aqueous phase and stabilized electrostatically. It is a concentrated mono-dispersion with particle sizes ranging from approximately 5 to 100 nanometers in diameter. The very-very fine particle size distribution in Hërmetix allows for rapid surface penetration, and the irregular variations in the surface area make rapid bonding with calcium hydroxide [Ca(OH)2] in the concrete possible. It can be applied to freshly-poured concrete slabs as soon as it sets, while the concrete is still wet. It will also perform brilliantly with concrete slabs that are decades old.


  • Hërmetix has more reactive sites, so it goes to work quickly, within 1-2 minutes
  • No brooming or working the material required
  • It penetrates deeply and reacts more efficiently.
  • No overnight curing required
  • No caustic gel to scrub off; nothing to dispose off; the only residue may be a small amount of safe powder that can be vacuumed off during polishing phase
  • No whitening potential
  • Non-hazardous; zero VOC
  • Low pH (~8.7) — safe to handle
  • Does not trap free, migrating moisture in concrete slab
  • Increases floor reflectivity, helping to reduce facility lighting and energy needs
  • Fills the pore structure of the surface layer, making it denser and harder
  • Increases stain and abrasion resistance


  1. Use 1 part of Hermetic densifier to 4 parts of potable water
  2. Apply with pump sprayer to saturation, a maximum rate of 500ft²/ga. Keep applying to maintain saturation, approximately 15 minutes.
  3. Let the concrete surface dry, approximately one hour, and commence with polishing/burnishing process.
  4. Excess material dries to a non-crystalline powder that can be swept with a broom.

Hërmetix Shield | protective finishing conditioner

Hermetic shield is a finishing conditioner applied after polishing the concrete surface. It introduced additional Colloidal Silica to the slab, along with a thin, clear polymer layer that gives extra protection to the concrete surface. It brings out the colour in integrally pigmented, stained or dyed concrete.

Hermetic shield provides extra protection against accidental staining from spills. It is particularly useful against mild acids (e.g., environments where food is handled or served).


  1. Use 1 part Hermetic shield to 1 part potable water
  2. Apply with pump sprayer at a maximum rate of 2000 ft²/ga and work in with a micro-fiber mop
  3. After two coats, use high speed burnishing to increase the shine
