The painted floor of our unfinished basement had a large damaged area that I chiseled out and then filled with a Quikrete patching product. However, it came out like very coarse sandpaper in surface texture, while the rest of our basement is smooth and easy on the soles of our feet.
What did I do wrong? Is paint the only difference between rough and smooth, or should I have used a particular material? What can we do now?
