Concrete Shield™ Densifier

Concrete Shield™ Densifier is a ready to use, silicate blend of Potassium and Lithium solution used to polish, harden, and seal green or aged concrete. The silicate solution penetrates concrete to react and produce a dust-free surface with improved resistance.

Polished Concrete Floor Melbourne


Concrete Shield™ Densifier is suitable for interior and exterior use, with common applications in warehouses, restaurants, retail shops, and car parks. Concrete Shield™ Densifier gives good abrasion resistance, penetration, and excellent clean-ability. It reacts with calcium hydroxide in concrete to produce improved resistance and provide a dust-free finish. Suitable for Warehouses, Restaurants, Retail stores, Car parks and residential.

Construction, Concrete



Apply in one undiluted uniform coat at an application rate of between 5-8 m2 /L (depending on the porosity of the substrate). To achieve maximum penetration, scrub material into the surface with a stiff bristle broom or an industrial floor-scrubbing machine for a minimum of 30 minutes until product begins to gel or becomes slippery. Wet material lightly with water spray and rework it into the surface for an additional 10 to 20 minutes. Following this, rinse the floor and remove any excess material with a squeegee and wet vacuum. Do not allow the material to pond. On porous rough-textured or broom finished surfaces, a second application may be required and should be applied 2-4 hours following the first coat. Floors can be returned to service 4-6 hours following removal of excess material.

DENSIFIER IN GRIND / POLISH SYSTEM Applied by spray or squeegee to the surface between grinding stages. Optimum results are achieved with two applications: one in the early stages of the grind, the second in the late stage of the grinding process. NOTE: Do not apply at the polishing stage.

SEALER Apply by spray method evenly at the prescribed rate. For best results, floors should be treated 7-14 days after placement. Concrete less than 3 days old may contain excess moisture that will inhibit full penetration of Concrete Shield™ Densifier.



Not suitable for use on natural stone Do not apply over areas previously treated with concrete curing compounds or membrane-forming sealers unless these have been completely removed.

Concrete Shield™ Densifier cannot be expected to make bad disintegrating concrete good. This product will not effectively work on lightweight, extremely porous, or worn concrete.
