I was cleaning the concrete floor from paint stains with paint remover. The concrete coating went off too!?

I overpainted the floor with the spraypaint on the patio. Then I used the paint remover. While scrubbing with a sponge I took away the colored concrete from the patio as well. Now I don't know how to fix it again!





It is a concrete coating that feels like gum, probably used as a sealant. I live in an apartment and I would like to fix this on my own.

Go to your local home improvement store, Lowe;s, Home Depot, etc. Explain to someone in the paint department what you did and ask their advice.
