Fast-setting joint compound is the best choice for quick repairs due to its unique formulation that allows it to dry rapidly. This type of compound is specifically designed to harden quickly, typically within a few hours, making it ideal for situations where immediate work or re-coating is required. Its quick drying time allows for faster project completion, which is particularly useful in repair scenarios where time is of the essence, such as in residential or commercial remodeling.

While other types of joint compounds have their advantages—such as all-purpose joint compound being versatile for various applications or lightweight joint compound being easier to handle—none can match the speed of fast-setting compounds when it comes to drying and curing. This characteristic makes fast-setting joint compound the preferred choice for quick touch-ups or repairs. Vinyl joint compounds have good adhesion and flexibility but do not offer the same rapid drying times necessary for urgent repair work.
