Why Is my concrete splotchy?
AND Can anything be done about it
Have you ever saw (or even have) uneven; light here and dark there or splotchy concrete?
Laying concrete isn’t an exact science, and there are a variety of factors that can contribute to concrete discoloration from the very beginning. These factors include:
- Variability in concrete mixtures
- The use of too much or not enough water
- The use of calcium chloride
- Improper concrete laying techniques
- Outside temperatures
- Exposure to water and salt
- Uneven application or wear of curing agent
In the case of uneven application or uneven wear of the curing agent, It will correct over time. The curing agent will wear off of your concrete. It Is recommended that you properly seal your concrete after this evens out (usually a few months after concrete Is poured)
Am I Stuck With this Splotchy Concrete Forever?
No! You can still fix this situation, but you will have to put some work and time into the process.
Your first step will be flushing and scrubbing the area. This involves soaking the concrete in hot water and then scrubbing it with a hard brush. The goal here is to even out some of the variability in the concrete’s moisture and mineral build-up. You may have to do this several times, but as soon as the concrete dries without discoloration, you will want to make sure to seal it again to preserve the work you’ve done.
Alternatively, you could consider using a concrete stain top coat to even out the blotchiness. Of course, this would involve having to first strip the seal/curing agent.
