I have a large in ground pool. Construction is painted concrete. About three years ago I had the pool painted. Some months after the pool was painted bubbles started to appear in the paint. I called the painting contractor back and he patched it up. However again the paint bubbled. It continues to get worse year by year.
I now want to repaint it, but am worried it will bubble again. Any ideas on what may have caused the bubbles. The paint was was chlorinated rubber.
