Restoring Dry Spackling Compound: A Step-by-Step Guide

Quck answer

Restoring dry spackling compound is a simple process. First, gather your materials: a putty knife, sandpaper, and a damp cloth. Start by using the putty knife to scrape away any loose or damaged compound. Next, use the sandpaper to smooth out the surface. Be sure to feather the edges to blend the repaired area with the rest of the wall. Finally, wipe away any dust with a damp cloth. Allow the compound to dry completely before applying paint or wallpaper. With these steps, you can easily restore dry spackling compound and achieve a seamless finish.


Spackling compound, commonly used for filling holes, can become hard and unusable if left exposed to air for too long. However, there is a way to revive it using water. In this guide, we will walk you through the process of restoring dry spackling compound to its original form.

Step 1: Breaking the Compound

Start by removing the lid from the container of spackling paste. Use the sharp end of a screwdriver to stab and poke at the compound until it breaks into small marble-sized chunks or even smaller pieces.

Step 2: Adding Water

Pour 1/4 cup of warm water into the container with the broken spackling compound. Mix and continue stabbing at the compound until the chunks begin to smooth out and become smaller in size.

Step 3: Mixing and Cutting

Using a putty knife, insert it into the spackling compound and start slicing at the chunks, cutting them down into even smaller pieces. Keep stirring, slicing, and mixing until all the chunks are gone. If needed, add more water gradually (1 tbsp. at a time) until the mixture becomes chunk-free.

Step 4: Achieving the Desired Consistency

Insert a stick into the container and continue stirring. Add more water gradually (1 tbsp. at a time) until the mixture reaches the consistency of very thick batter. It should be pliable and able to stick on a putty knife, but not overly runny.
