Best Practices for Decorative Concrete Flatwork

Finishing Decorative Concrete

Protect the concrete surface from rapid evaporation of bleed water. Use Confilm® evaporation reducer from BASF as needed.

Texture all surfaces adequately and uniformly for slip resistance.

Finish all surfaces consistently and at similar times after placement.

Finish the edges first and do all handwork in the same direction.

Do not sprinkle water or add water to the surface during finishing operations. This will lighten the surface color.

Over-troweling or burnishing the concrete surface will cause discoloration and darkening of the surface color.

Curing Decorative Concrete

For best results, all decorative concrete should be cured. Do not use plastic sheeting or water method to cure decorative concrete.

Use BASF’s Kure 1315 water-based curing compound or a compatible curing compound.

Until it is completely cured, the color of concrete is normally less uniform and appears darker than the final color.

Do not allow items to stand on the concrete during and immediately following the curing process.

Ordering Decorative Concrete

  • Use the same quality concrete mix design and water/cement ratio and maintain a consistent slump throughout the project. The use of admixtures from BASF can improve concrete workability while maintaining lower water/cement ratios.

  • To maintain color consistency, order decorative concrete in minimum 3 yd3 (2 m3) increments.

  • Calcium chloride accelerators will discolor the concrete surface. Use non-chloride accelerators from BASF to achieve fast concrete set time.

Placing Decorative Concrete

  • Place concrete on a well-drained sub-grade that has adequate and uniform load-bearing characteristics and is thoroughly compacted and dampened.

  • Adding water on-site to achieve a higher slump will lighten the color.

  • Place concrete close to its final position to avoid potential segregation.

  • Do not place concrete over freestanding water or muddy, frozen or soft spots.

  • Concrete placed in the shade may display variations in color. This is normal and will subside in time.
