Discoloration or discoloring is one of the most common.
If you are using the same materials, mix and batch your concrete should have a consistent color. Changes in concrete color can occur just by using two different cements or if a chemical from a job site gets added to the mix, even different water sources can change the color of the concrete.
Solving discoloration problems:
- Discuss your tolerances with the supplier
- Water must be completely evaporated before concrete can be finished
- Make sure the entire surface is uniformly cured
- Use a consistent form release agent
Hardscapes Inc. uses these methods and many more to create perfect concrete structure every time.
