DiamondFinish Clear

ALWAYS WEAR PROTECTIVE GLOVES AND SAFETY GLASSES when using DiamondFinish Clear. Please heed all warning and caution notices on containers and cans.


DiamondFinish Clear is a single-component, ready-to-use, high-solid content, moisture-curing urethane with exceptional adhesion properties. DiamondFinish Clear is specifically formulated to encapsulate and seal porous surfaces like metal, wood, or even concrete. Concrete is an alkali material readily susceptible to moisture and chemicals because it is very porous. These agents readily penetrate its surface resulting in premature erosion and failure.

DiamondFinish Clear is an inexpensive and simple solution for protecting and sealing concrete permanently. Unlike other high-performance concrete coatings, DiamondFinish Clear is a single-component product with no mixing ratios involved. Simply stir and use. There is no special equipment needed. On top of that, DiamondFinish Clear is UV stable so it will not yellow when it is applied to surfaces that can be exposed to sunlight.

When first applied, DiamondFinish Clear’s thin viscosity wets and penetrates the surface and, as it combines with atmospheric moisture, the curing process of resins begins. This unique curing mechanism allows DiamondFinish Clear to expand and interlock within the pores of the concrete enabling it to become part of the surface. This extremely tough yet flexible coating then seals the surface, blocks all pores and prevents all access to moisture. DiamondFinish Clear is also highly resistant to mechanical abrasion and impact.

Once concrete is sealed with DiamondFinish Clear, its finished surface will become extremely tough, durable and chemically resistant allowing for easy clean up with little or no maintenance.

To achieve expert results, please take the time to carefully read and understand the following directions before you begin your project. These directions are meant to be general guidelines only and do not cover every application or environmental situation. If you have remaining questions or concerns, please call us for technical assistance.

ALWAYS WEAR PROTECTIVE GLOVES AND SAFETY GLASSES. Always work in a well-ventilated area and wear protective gloves to avoid skin contact & temporary staining.

Apply DiamondFinish Clear to clean seasoned concrete floors in indoor garages or industrial areas. Do not apply to new concrete for at least 60 days until it is fully cured. Recommended floor temp application range is 55-82°F degrees. DiamondFinish Clear is a moisture-cured urethane. For best end results, use only in moderate to dry atmospheric conditions. AVOID applying DiamondFinish Clear in extreme humid conditions. Any unwanted DiamondFinish Clear must be cleaned up before it dries as it cannot be removed by any solvent once cured. The key to any long term coating performance is good prep work.


Sweep or use a shop vac to remove any loose debris and contamination. Scrape off any stuck on debris with a scraper or shovel. Wash the surface with KBS Klean, a water-based cleaner / degreaser. Use a dilution rate most effective for the degree of contamination. Use a bristle brush or electric floor scrubber to help remove any dirt, grease or oil stains from the pores of the concrete. Repeat if necessary. Oil and grease stains are gone when water no longer beads up on the surface. Rinse thoroughly and let dry. If desired, fill any cracks or pits as directed with NuMetal Epoxy Putty or similar filler.


Apply an acid wash (muriatic acid) or refinish the concrete (concrete grinding) to remove a thin layer of the surface for the highest level of adhesion and bonding. Rinse well and let dry completely. Use a fan or dehumidifier to help facilitate drying. To test for residual moisture in the concrete, securely seal a 2-3 foot area of concrete with plastic wrap and tape. Leave overnight. If no condensation forms on the plastic wrap, the concrete is dry and ready for sealing with DiamondFinish Clear.


Do Not Shake DiamondFinish Clear Can. Stir contents thoroughly for at least 3-5 minutes. Apply two light-medium coats of DiamondFinish Clear by roller to dry concrete. Always apply the second coat within 8 hours of the first. Under normal atmospheric conditions, let cure for 7 days before resuming full traffic.

NOTE: Please read and follow full DiamondFinish Clear application instructions for all precautions and warnings. For future maintenance, if coating becomes damaged, simply clean, scuff, and recoat the spot with DiamondFinish Clear.


KBS #1 Thinner is ideal for clean up. IMPORTANT: DiamondFinish Clear must be cleaned up before it dries. It cannot be removed by any solvent once cured. Remember to always wear protective gloves to avoid skin contact and temporary staining. If skin contact accidentally occurs, immediately remove with KBS #1 Thinner followed by soap and water.
