- Topping Compound: This type of compound is used for the final coat of finishing. It has a smoother consistency than an all-purpose compound, making it easier to achieve a flawless finish.
- Setting Compound: This compound sets through a chemical reaction, rather than drying through evaporation like other types. It is ideal for quick repairs or projects that require a fast turnaround.
