Super Diamond Clear is a state-of-the-art concrete curing compound and cure & seal specially designed with a high solids formulation to provide the most efficient moisture retention for proper cement hydration and strength gain, as well as protection from liquids, weathering, and abrasion. Super Diamond Clear is particularly well suited for exterior architectural concrete where membrane yellowing is undesirable. It is formulated with a unique exempt solvent blend that gives this product all the performance benefits of traditional solvent-based curing and sealing products while ensuring compliance with VOC laws in regulated areas. Super Diamond Clear 350 can be tinted with Euclid Universal Color Packs, which are available in 33 standard colors.

Primary Applications

  • Driveways & exterior pavements
  •  Walls and columns
  •  Exposed aggregate
  •  Dry shake floors
  •  Curing and sealing decorative concrete


Super Diamond Clear is a clear liquid in the container. After application and drying, it will greatly darken concrete, and will have a high-gloss finish. A small test area is strongly recommended to confirm appearance prior to beginning full application.

Surface Preparation

For existing concrete, the surface must be clean of any and all surface contaminants, and free of standing water. If applying 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 and the old sealer. When applying to freshly poured concrete as a cure & seal, the surface bleed water must be allowed to evaporate prior to applying, and the surface must be hard enough as to not be marred during product application.


Requires no pre-blending prior to use. If using Euclid Universal Color Packs
or Euco Grip with this sealer, please refer to those products’ technical data sheets for mixing instructions.


Apply at the recommended coverage rate using an industrial, solvent-resistant pump-up sprayer with a high-solids nozzle and a short-nap, solvent-resistant 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 backroll over sprayer lap marks for best appearance. 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. Redistribute any puddles or runs before it dries. Protect freshly coated surfaces from rain or heavy fog for a minimum of 12 hours after application. Backrolling must immediately follow spraying, as this product dries quickly.

Application of Super Diamond Clear too heavily, in too many successive coats, or in multiple coats from re-sealing too frequently can cause 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 in hot weather/direct sunlight or onto a hot surface can cause bubbling.


Tools and equipment may be cleaned with Euco Solvent, xylene, or acetone (always follow package directions and warning labels) immediately following use. Clean drips and overspray with one of the above solvents while still wet. Run cleaning solvent 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.
