I have flaking sealer and faded areas on some old stamped concrete. How can I fix it?
Ask a Pro
Q. - I have a Large area of Stamped Concrete, Grey in color around my pool. It is about 10 years old. I have sealed it every other year. It is starting to pit / flake in certain areas and the color is very faded. What product should I use to paint or stain it to give it a fresh look. Thank you
If it's the sealer that is flaking off, then what appears to be faded concrete color may simply be an unsealed surface that would come back to life once the sealer was re-applied. If the concrete's color comes back when the concrete is wet or damp, then you should strip off the remaining sealer and then reseal it.
If you do find that the concrete needs to be stained, then an acid stain will work fine so long as all the sealer is off and the stain can get into the pores of the concrete.
If the flaking is the concrete itself is spalding off, then the surface of the concrete is losing it's structural surface integrity, which can be caused by many different reasons. Once this has began it will only continue and will eventually need to be removed and replaced with new concrete. In the meantime though, you can camouflage it with acid stains. Also, sealing the entire area may help to slow down the spalding and extend the life of the concrete.
I hope this helps
