Product Best For: Stamped flatwork with a natural charcoal accent. This ready-to-use hardener is designed for both interior and exterior surfaces and provides long-lasting color with UV resistance. It helps seal the surface while adding color in a single pass, making it suitable for decorative concrete projects.
Why selected: It combines ease of application with durability and color fidelity, reducing the need for multiple steps in stamped concrete installations.
Tip: Avoid over-application in very hot conditions to prevent color inconsistency.
BonWay True Color Hardener Brick Red
Product Best For: Bold red accents on flat concrete surfaces. The non-metallic blend is applied via shake-on or broadcast methods, commonly at about 60 lbs per 100 sq ft, with higher coverage for lighter or pastel shades.
Why selected: The brick red option provides a strong, classic decorative color that remains stable under UV exposure, ideal for driveways and patios with a warm palette.
Caution: If using lighter shades, plan for higher coverage to achieve uniform color.
BonWay True Color Hardener Jet Black

Why selected: Jet black delivers strong depth and a contemporary look that pairs well with light grout or exposed aggregate textures.
Limitation: Dark colors can be more prone to showing dust or minor imperfections; proper finishing helps minimize this effect.

Why selected: It minimizes waste and simplifies cleanup, helping maintain a tidy workspace when dealing with leftover latex paints.
Limitation: Not a color hardener for concrete; best used alongside paint waste management rather than surface colorization.
Sakrete Cement Color (Buff) 10 Ounce
Product Best For: A buff, neutral color option that pairs with various sealers and finishes. It adds alkali and UV resistance to maintain color integrity over time.
Why selected: Serves as a reliable base pale tone for neutrally styled spaces or when customizing with other color accents is desired.

Buying Guide
What color tone do you want?
Choose color hardness based on the final look you desire. Dark colors like Jet Black or Brick Red create dramatic contrasts, while Charcoal Grey and Buff offer subtler finishes.
What application method fits your project?
Most options use a dust-on or broadcast method. If you’re stamping flatwork, ensure the product supports stamping textures and long-term durability in your climate.
What surface and environment?
Consider UV exposure, exterior versus interior use, and the concrete mix. UV resistance matters for outdoor installations; interior projects may prioritize color fidelity and ease of maintenance.
Do you need cleanup or disposal support?
Products like GLAINTE Waste Away help manage paint waste, which is useful in workshops. Distinguish between true color hardeners and ancillary products for cleanup when planning your workflow.
Coverage and color depth considerations
Higher coverage rates may be required for lighter shades. Check recommended lbs per 100 sq ft and adjust to achieve uniform color depth across the surface.
Compatibility and future maintenance
Ensure the chosen color hardener is compatible with your sealer and final finish. Plan for long-term color stability and maintenance tasks like cleaning and resealing.
