Spackle Drying Time Comparison Table

There are two main types of spackle: traditional spackle and lightweight spackle. Traditional spackle is made from gypsum powder, while lightweight spackle is made from a combination of various materials such as vinyl and acrylic resins. Both types of spackle have their own advantages and disadvantages, and the time they take to dry can vary depending on several factors.

Traditional spackle is typically the more affordable option, and it dries harder than lightweight spackle, making it a good choice for larger holes and deeper cracks. However, it can take longer to dry, sometimes up to 24 hours or more. On the other hand, lightweight spackle dries faster, often within a few hours, and it’s easier to sand than traditional spackle. However, it’s not as durable as traditional spackle, so it may not be the best choice for very large or deep holes.

When it comes to ingredients, traditional spackle is made from gypsum powder, which is a naturally occurring mineral that’s often used in construction and home improvement projects. Lightweight spackle, on the other hand, is made from a combination of materials such as vinyl and acrylic resins, which are lightweight and easy to work with. Some lightweight spackles may also contain fillers such as calcium carbonate or talc to add bulk and reduce weight.

To make a comparison table of the drying times for traditional and lightweight spackles, we can look at the following factors:

  • Size and depth of the area being spackled
  • Humidity and temperature in the environment
  • Type of spackle being used

Step by Step Instruction on How to Make How Long Does Spackle Take to Dry


  • 1 cup joint compound (also called drywall mud)
  • 1/4 cup water
  • 1/4 cup fine sanding dust or talcum powder (optional)
  • 1 tbsp. white glue (optional)
  • Small mixing bowl
  • Mixing tool (e.g. a spatula or putty knife)
  • Airtight container for storage


  1. Pour the joint compound into a small mixing bowl.
  2. Add the water, a little bit at a time, while stirring continuously. You may need more or less water depending on the consistency you want.
  3. If desired, add a 1/4 cup of fine sanding dust or talcum powder to help strengthen the mixture and provide a smoother finish. This step is optional.
  4. Optionally, add 1 tablespoon of white glue to the mixture, which can help the spackle adhere to surfaces better. Stir well to ensure that the glue is evenly distributed.
  5. Continue stirring the mixture until it reaches a smooth, creamy consistency. The spackle should be thick enough to fill in holes and cracks but not too thick that it’s difficult to spread.
  6. Test the spackle’s consistency by applying a small amount to a surface using a putty knife or a spatula. Adjust the water or powder content accordingly.
  7. Once you’re happy with the consistency, transfer the spackle to an airtight container for storage. Keep the container in a cool, dry place until you’re ready to use it.

It’s worth noting that spackle can be tricky to make at home, and it’s important to follow the steps closely to ensure that the mixture is consistent and the spackle dries properly. If you’re unsure about making your own spackle, it’s generally easier and safer to purchase pre-made spackle from a hardware or home improvement store.
