‘刮掉’ (guā diào) is a separable verb meaning 'to scrape off' — literally, 'to scrape' (刮) and 'to remove completely' (掉). The character 刮 refers to the physical action of rubbing or scraping with an edge or tool, while 掉 indicates removal, loss, or detachment, emphasizing that the scraped material is gone entirely. Together, they describe forcibly removing a thin surface layer — such as paint, frost, dirt, or skin — using friction or pressure.

This verb is commonly used in everyday contexts like household cleaning, cooking (e.g., scraping scales off fish), skincare (removing dead skin), or maintenance tasks (e.g., scraping old wallpaper). It implies effort and intentionality; passive or accidental removal is not expressed by this term. While often transitive (requiring an object), it may appear without one when context makes the object clear (e.g., ‘再刮掉一点’ — ‘scrape off a bit more’).
