On average, spackle takes 1 to 2 hours to dry and 24 hours to fully cure. When applying spackle, especially to interior basement walls, consider the type of spackle you’re using, the size of the repair, and environmental factors that can slow drying time. Different types of spackle include standard, epoxy, acrylic, vinyl, and quick-dry, each best-suited for different repair types and having varying drying times. Ways to reduce spackle drying time include using a dehumidifier, air conditioner, fan, or blow dryer to improve air circulation and remove moisture from the area. Learn about different types of spackle, the drying time associated with each, and how to reduce drying time.
