It seems that the post "nails chemistry" does not relate to maintenance report feedback for public flat house. The post is not about any facility, inconvenience, block number or street, or request for fixing something in a public flat house. It is possible that the user is simply expressing their interest in chemistry or nails, or perhaps they are using the term "nails" metaphorically. Without more context, it is difficult to provide a more specific explanation.
