The SLABHARD® Grind & Seal SB System is a decorative concrete grind and seal flooring system engineered to enhance, protect and extend the life of existing concrete surfaces in commercial, institutional and light-industrial environments. The system combines mechanical concrete preparation, crack and joint repair, penetrating primer technology and a UV-stable protective finish to create an attractive, durable surface while preserving the natural character of the concrete. Unlike resinous flooring systems that build a new surface over concrete, the Grind & Seal SB System enhances the existing substrate through controlled aggregate exposure and clear protective sealers, providing improved abrasion resistance, simplified maintenance, long-term UV stability and optional enhanced chemical resistance.
Recommended Uses
The SLABHARD® Grind & Seal SB System is suited for existing concrete surfaces requiring a decorative architectural finish with durable protection. Typical environments include:
- Commercial buildings
- Educational facilities
- Healthcare facilities
- Manufacturing facilities
- Retail spaces
- Warehouses
- Laboratories
- Automotive showrooms
- Automotive service areas
- Aircraft hangars
- Institutional facilities
Exclusions: This system enhances existing concrete rather than creating a new resinous flooring surface. Final appearance depends on the condition, density and composition of the existing concrete substrate, and aggregate exposure levels cannot be guaranteed until mechanical grinding begins. Consult individual product Technical Data Sheets and confirm substrate and environmental suitability before installation.
Advantages
- Decorative Concrete Finish → Natural Architectural Appearance:
Controlled mechanical grinding exposes the existing concrete and aggregate to create a decorative architectural finish while preserving the natural character of the substrate. - Multiple Aggregate Exposure Options → Configurable Finished Appearance:
Salt & pepper, medium aggregate and full aggregate exposure options provide flexibility in the finished appearance based on project design requirements and existing substrate conditions. - UV-Stable Finish → Long-Term Appearance Retention:
UV-stable, non-yellowing protection helps preserve the finished appearance of the concrete over time. - Improved Abrasion Resistance → High-Traffic Performance:
The protective finish provides improved abrasion resistance for commercial, institutional and light-industrial environments. - Interior and Exterior Capability → Application Flexibility:
The system is suitable for both interior and exterior applications when installed according to published specifications. - Optional Enhanced Chemical Resistance → Performance Flexibility:
SLABSEAL® 100 may be specified as the finish coat where enhanced abrasion, stain and chemical resistance are required.

Frequently Asked Questions
What Is the SLABHARD® Grind & Seal SB System?
The SLABHARD® Grind & Seal SB System is a decorative concrete grind and seal flooring system that enhances existing concrete through mechanical grinding followed by application of protective clear sealers.
What Environments Is This System Designed For?
The system is suited for commercial buildings, educational and healthcare facilities, manufacturing facilities, retail spaces, warehouses, laboratories, automotive showrooms and service areas, aircraft hangars and institutional facilities.
Is the SLABHARD® Grind & Seal SB System a Coating?
No. It is a decorative concrete grind and seal system that enhances existing concrete through mechanical grinding followed by application of protective clear sealers.
Does This System Cover Imperfections in the Concrete?
No. Existing concrete characteristics including aggregate, color variation and many natural imperfections remain visible and become part of the finished architectural appearance.
What Determines the Finished Appearance?
The level of grinding, aggregate exposure selected and condition of the existing concrete substrate collectively determine the final appearance.
Can the System Be Used Outdoors?
Yes. The system is suitable for both interior and exterior applications when installed according to published specifications.
Which Topcoat Should Be Selected?
SLABSEAL® 250 is the standard decorative finish providing UV stability and unlimited recoat capability. SLABSEAL® 100 should be specified where greater abrasion, stain and chemical resistance are desired.
Can Every Project Achieve Full Aggregate Exposure?
Not necessarily. Aggregate exposure depends on the existing concrete placement, finishing practices and grinding depth. Final appearance cannot be guaranteed until grinding begins.
