Task: Sentiment Analysis
Input (English): I bought this product to fix some scratches on an exterior brick wall of my home. The instructions were easy enough and it worked as promised. However, after only a month, the finish looked like it was flaking. My paint is fairly new, so I've tried sealing off these spots several times with various kinds of products and sealers, but they just continue to get worse - not better.
Output (English): Bad review
