Hairline Crack Repair & Refined Surface Overlay
Crack Fill & Grout Coat™
Structural Ultra-thin Topping & Penetrating Protection.
For the finest details, Crack Fill & Grout Coat™ provides the critical finish coat. When applied as a Crack Fill, this ultra-fine mortar is engineered specifically to penetrate and fill hairline cracks, preventing water intrusion and protecting the substrate from further environmental damage. When applied as a Grout Coat, it can provide an ultra-thin, high-strength overlay at less than 3/64” (1mm) that acts as a durable visual enhancement. The result is a continuous, uniform surface across the entire project that mirrors the look of a new pour while offering superior protection. Crack Fill & Grout Coat™ also accept liquid and powder pigments.
While structural repairs handle the heavy lifting, the integrity of a project often lives or dies in the details. Crack Fill & Grout Coat™ is engineered as the ultra-fine evolution of our Surface Armor™ technology; designed specifically for high-definition restoration where standard mortars cannot penetrate.
By utilizing a refined micro-aggregate, this formulation bridges the gap between deep structural repair and aesthetic perfection, providing a monolithic seal that protects the substrate from the top down.

Components of the Crack Fill & Grout Coat™ System
The Crack Fill & Grout Coat™ System requires the application of Ecobeton®- USA Vetrofluid® which allows it to sustain heavy use, including vehicular traffic. (www.ecobeton-usa.com)
The Role of Ecobeton® Vetrofluid®
For optimum performance, a final application of Ecobeton® Vetrofluid® serves as a permanent internal catalyst that:
Fortifies the Matrix
Triggers a crystalline reaction that seals the surface against water, salts, and oils.
Enables Heavy Use
Provides the wear resistance necessary for high-volume vehicular traffic.
Future-Proofs the Repair
Blocks chloride ion penetration and carbonation, preserving both the repair and the underlying substrate.
Ductile Performance for Rigid Demands
Crack Fill & Grout Coat™ - For Precision Concrete Finishing
Fills and hides micro cracks
Capillary Penetration Engineered with a specialized rheology to wick into hairline cracks, displacing air and moisture to create a permanent, water-tight seal.
Seamless ´Like New´Aesthetic Continuity
It eliminates the patchwork look of infrastructure repairs by providing a uniform, new-pour seamless finish across the entire project.
Significantly increases lifecycle
Beyond aesthetics, the ultra-dense matrix acts as a primary defense against chloride ion penetration and carbonation, significantly extending the life of the underlying concrete.
Accepts liquid and powder pigments
It is highly versatile for design. Liquid or powder pigments can be added into the mix to achieve custom colors that go beyond standard "cement gray".
Fast and easy to apply
Like Surface Armor™, Crack Fill & Grout Coat™ is engineered for a quick "mix-and-go" workflow. Its flowable consistency allows for rapid coverage with minimal specialized equipment.
Interior and exterior use, including drive surfaces
It is tough enough to handle the weight of vehicles on driveways, yet refined enough for interior floors.
Extremely abrasion resistant
Once cured, it creates a dense surface that resists scuffing, scraping, and heavy foot or vehicle traffic better than any standard concrete overlay.
