I have an issue with crumbling concrete steps that I hope someone here can help me with.
House was built in 1948, the step are original as far as I know. Former owners painted the porch, and then at some point they were covered with outdoor carpet; I assume to conceal the deterioration.
Last summer I pulled off the carpet, and scrapped off all the paint that I could. I got rid of all the lose cement, and then put in some screws and wire so the concrete patch would have something to grab onto.
I went to Lowes and bought Quikcrete Vinyl cement patch, and either their Hardener or Fortifier (I cant remember which one I used. I might be able to find the bottle in the garage though). I followed their directions, and did the best I could to reform the corner of a step that was missing, and fill some other small areas.
It turned out great, I was very happy with it. We let it set for a couple weeks and then painted the entire porch. Midway through the winter we noticed the paint starting to bubble and peal. Soon the cement was coming off in small layers, and then started to come off in bigger chunks.
Does anyone have any idea why this happened? Or what I did wrong?
THANKS
