One of our Walmart account has red dyed concrete. It was poorly sealed this past winter by someone else and had a milky white sealant. Problem for them is they have a lot of gum issues. I told them more frequency would help keep the gum from staining the concrete. This has been working well enough even though I had to remove the sealant. They pulled back on frequency for two months and the gum volume at their entrances is large and I am concerned that it is going to look rough even once cleaned. Other than frequency is there anythin I can do for this type of concrete. Sealing it isn't an option as gum is always having to be removed. I'll post a couple of pics soon. Anyone have the same challenge?
