I have this coating on my front porch which is starting to disintegrate. I think the porch slab is probably still good, so I want to just replace the coating but I can't figure out what it is. I'm almost positive that it was added to the porch to add traction; especially when wet. Can someone help me identify this? I could also use some advice on how to replace it... I'm looking for a good solution to clean up how this looks, not necessarily a perfect solution.
This coating is very hard like the cement, and became damaged from salt, also similar to cement.
