Super Diamond VOX: Concrete Seal


Super Diamond Clear VOX is a VOC compliant, water-based acrylic curing and sealing compound. This product provides a quality cure to freshly placed interior or exterior concrete while assuring total resistance to yellowing from ultraviolet exposure. Super Diamond Clear VOX helps control hydration of cement by preventing rapid loss of moisture through the surface of newly placed concrete. Super Diamond Clear VOX can also be used on existing concrete, giving surfaces a glossy appearance and a protective seal.

Milky white liquid in the container. After application and drying, it will slightly darken concrete, and will have a medium to high-gloss finish. A small test area is strongly recommended to confirm appearance prior to beginning full application.

Primary Applications

  • Curing and sealing concrete where a non-yellowing, glossy finish is desired

Application: ft2 /gal (m2 /L)

-Curing a Sealing Fresh Concrete:

First Coat:  200-300 ft/gal (4.9-7.4)
Second Coat (Optional): 300-400 ft/gal  (7.4-9.8)

-Sealing or Re-Sealing Existing/Cured Concrete

First Coat: 300-400 ft/gal (7.4-9.8)
Second Coat: 400-500 ft/gal (9.8-12.3)

NOTE: Coverage rates are approximate. Actual coverage depends on temperature, texture, and substrate porosity. Avoid excessive build-up of sealer, as this may cause discoloration and/or poor product performance.

Directions for Use

Surface Preparation:

For existing concrete, the surface must be clean of any and all surface contaminants, and free of standing water. If applying Super Diamond Clear VOX to previously sealed concrete, call Euclid Chemical to check compatibility. If the chemical makeup of the previous sealer is unknown, a small test section is strongly recommended to check compatibility between Super Diamond Clear VOX and the old sealer. When applying Super Diamond Clear VOX to freshly poured concrete as a cure & seal, the surface bleed water must be allowed to evaporate prior to application and the surface must be hard enough as to not be marred during product application.


Requires no pre-blending prior to use. Euclid Chemical water-based cure & seals, are not compatible with Euclid Universal Color Packs or Euco Grip. If use of color or slip-resistant additive is desired, consider using a Euclid Chemical solvent-based cure & seal instead.


Apply at the recommended coverage rate using an industrial pump-up sprayer with a high-solids nozzle and a short-nap roller. Apply sealer uniformly to the concrete using sprayer, then lightly backroll the sealer to ensure even coverage. Maintain a “wet edge” while spraying, and back roll over sprayer lap marks for best appearance. Super Diamond Clear VOX may be applied by roller alone, but extra care must be taken to ensure that the sealer is applied uniformly, and at the proper coverage rate. Re-distribute any puddles or runs before it dries. Protect freshly coated surfaces from rain or heavy fog for a minimum of 24 hours after application. Application of Super Diamond Clear VOX too heavily, in too many successive coats, or in multiple coats from re-sealing too frequently can cause failure to dry completely, bubbling, whitening, peeling, flaking, and ultimately, failure of the product. To prevent over-application, it is good practice to measure the area to be sealed and then measure the corresponding volume of product required based on the coverage rate. In addition, applying Super Diamond Clear VOX in hot weather/direct sunlight or onto a hot surface can cause bubbling.


Tools and equipment may be cleaned with warm, soapy water immediately following use. Clean drips and overspray with warm, soapy water while still wet. Run warm, soapy water through spray equipment to remove residual materials and prevent clogging of nozzle in future use. If not cleaned immediately, the sealer may leave an unwanted residue on painted surfaces, glass, or wood.


Hardened/dried Super Diamond Clear VOX may be removed with a strong solvent such as xylene/xylol or MEK (always follow package directions and warning labels). Euco Clean and Strip is a citrus-based stripper that may also be used to remove this product. Alternatively, the product can be removed by sandblasting or other mechanical means.

Consult the product Safety Data Sheet  and Technical Data Sheet before use.
