Mixing drywall mud is no easy task. The consistency of the mixture can change drastically based on how much water you add, and there are many different types of mixers to choose from. If you’re not careful, your drywall mud can be too thin or too thick- both will end up costing you time and money in the long run.
Use this article on how to mix hot mud for drywall to help identify what type of mixer to use for your project and how much water should be added. You’ll also learn about the importance of using a trowel instead of a putty knife when mixing!
What is Hot Mud?
Mud or joint compound is commonly known, is a mixture of a binder and a filler. The most common type of mud used in drywall finishing is lime-based plasters that have been dried out to the point where they have little resistance to water.
The binder is usually some form of gypsum, which comes in many forms, or cement. The filler component is sand which provides the bulk of the material, and most importantly, it must be wonderful sand. For plasterboard preparation, lime-based products are used because they are much stronger when dry than cement products.
Tools and Materials
- Joint Compound
- Water Pump or Bucket
- Long Spatula for Mixing. The scraper works well too.
- Shovel or Stiff Broom to speed up the drying process.
A Step by Step Guide on How to Mix Hot Mud for Drywall
Step One :
The first step is to have a mixing container with a spout. A good size for a 5-gallon bucket is about 20 inches long and 12 inches wide. This will give you plenty of room to work.
Pour the required amount of water into the bucket. For example, for a 5-gallon bucket, you will need about 3 gallons of water.
The joint compound adds enough to make a thick mud (about the consistency of toothpaste).
Step Two :
Fill the container with water just below the spout lip level. Note, if there are any large chunks of debris in the mud that you would mix, then be sure to use clean water, not sandblasting dust pile runoff. Trust me; it will still sandblast your lungs if you inhale it/ingest it even after it dries out (bleach).
Also, note how much water was added to this bucket because this will be your guide for future mixes. Too little water, and it won’t be easy to get an even blend. Too much water and life become miserable when you switch to drywall taping.
Step Three :
Using the long scraper or spatula, begin mixing in a speedy sliding manner until many lumps are removed (about 1 minute). You don’t need to go overboard, but pay close attention to how smooth the consistency is.
Don’t forget to scrape off the lip of your bucket now and then while mixing other batches. This step will help in how to mix hot mud for drywall.
Step Four :
After the initial mixing, it is time to add more mud. Pour in the same amount of mud as water that was added initially (in this case, 3 gallons). Mix until all lumps are gone and it has a smooth consistency.
Step Five :
Now that the central mix is complete, you need to add the water. Slowly add water until the desired consistency is reached. It should be thin enough to pour but thick enough to hold a shape.
The goal is to have lovely, workable mud that doesn’t slide off the trowel when applying it to the drywall.

Step Six :
If you will be using the mud within an hour or two, go ahead and shovel it out of the bucket and onto the drywall.
If you are not going to use it for a while, cover the top of the bucket with a lid or plastic wrap and put it in a safe place.
When you’re ready to use it again, remove the lid or plastic wrap and remix as described in steps 2-5. That’s it! You have now successfully mixed hot mud for drywall.
If you have trouble mixing the mud, try adding more water until it reaches the desired consistency. It should be thin enough to pour but thick enough to hold a shape. Also, make sure to remix any mud sitting for more than an hour or two. The longer it sits, the harder it becomes to mix.
- Do not use hot mud near flammable materials.
- Do not use a flame to heat the mud.
- Do not get the hot mud on your skin.
- If you get the mud on your skin, immediately flush it off with cold water.
- Do not ingest the hot mud.
- If you do ingest the hot mud, seek medical attention immediately.
Should You Mix Premixed Drywall Mud?
If you’re a professional drywaller, the answer is probably no. Premixed drywall mud is designed for the novice, and it can be challenging to get the hang of using it correctly. It’s also more expensive than mixing your own. So here are some reasons to mix mud in your bucket.
If you’ve ever tried mixing the dry ingredients that go into premixed drywall mud, you know it’s a long, messy process involving two people constantly stirring for nearly an hour with a giant spoon. But, how much easier it is to dunk your trowel straight into the five-gallon pail!
If you’re mixing all of your mud from scratch every day, nothing at all – except for one thing: premixed drywall mud isn’t designed for consistency. If you pour out a big batch of premix today and then come back tomorrow to get more, the chances are good that it won’t measure up. Although the ingredients are all there, they’ve been sitting in the pail for who knows how long, and they’ve had a chance to blend – not what you want when you’re plastering a wall.
