Can DiamondFinish Clear Be Used to Seal Concrete?
Yes. DiamondFinish Clear is a single-component, ready-to-use, high-solid content, moisture-curing urethane specifically formulated to seal porous surfaces like metals, wood, and concrete. Concrete is an alkali material readily susceptible to moisture and chemicals because it is very porous. DiamondFinish Clear penetrates and seals these pores permanently, protecting concrete from moisture damage and chemical attack.
DiamondFinish Clear is an inexpensive and simple solution for protecting and sealing concrete indefinitely. Unlike other high-performance concrete coatings, DiamondFinish Clear is a single-component product with no mixing ratios involved. Simply stir the can and apply — no special equipment, no hardener, no mess.
⭐ Pro Tip — Single-Component, Ready to Use Unlike two-part epoxy or polyurethane systems that require precise mixing ratios and hardeners, DiamondFinish Clear is a single-component formula. Simply stir the contents thoroughly for 3-5 minutes and apply. No mixing calculations, no wasted material, no failed batches. |
How DiamondFinish Clear Seals Concrete
When first applied, DiamondFinish Clear's thin viscosity wets and penetrates deep into the concrete surface. As it combines with atmospheric moisture, the curing process of the moisture-cured urethane resins begins. This unique curing mechanism allows DiamondFinish Clear to expand and interlock within the pores of the concrete, becoming an integral part of the surface itself.
Once cured, the resulting coating is extremely tough yet flexible. It seals the surface completely, blocks all pores, and prevents all moisture access from below. DiamondFinish Clear is highly resistant to mechanical abrasion, impact, and chemical attack — including fuel, solvents, battery acid, and brake fluid.
What Makes DiamondFinish Clear Different Once sealed with DiamondFinish Clear, concrete becomes extremely tough, durable, and chemically resistant — requiring minimal maintenance. The sealed surface is easy to clean and resists staining, making it ideal for garage floors, warehouse areas, and other high-traffic concrete surfaces. |
Frequently Asked Questions
Do I need to prepare concrete before applying DiamondFinish Clear?
Yes. Clean the concrete thoroughly with KBS Klean to remove dirt, grease, and oil. Then perform an acid wash or concrete grinding to remove a thin layer of the surface for the highest level of adhesion. Rinse well and allow the concrete to dry completely. Test for moisture by sealing a 2-3 foot area with plastic wrap overnight — if no condensation forms, the concrete is ready for sealing.
How long does DiamondFinish Clear take to cure on concrete?
Under normal atmospheric conditions, allow 7 days for DiamondFinish Clear to fully cure before resuming foot traffic or heavy use. You can apply a second coat within 8 hours of the first coat.
Can DiamondFinish Clear be applied in humid conditions?
DiamondFinish Clear is a moisture-cured urethane, so it actually needs atmospheric moisture to cure properly. However, avoid applying it in extreme humidity. For best results, apply in moderate to dry atmospheric conditions with a temperature range of 55-82°F.
