Set Hot Mud and Drywall Repair
Pros and Cons of Hot Mud for Drywall Taping and Mudding
By Mark J. Donovan
If you are planning to do some
drywall work you may want to consider using quick set hot mud as an
alternative to using joint compound. Professional drywall contractors use it
all the time on large drywall projects. Quick set hot mud is particularly
ideal for making minor drywall repairs if you are looking to make a quick
Although drywall contractors use quick set hot mud regularly on large
drywall projects, I would not recommend it for the weekend DIY warrior who
has a large drywall project.
As the name implies, quick set hot
mud sets up quickly. It also is more difficult to sand than standard joint
compound. Thus you really need to know what you are doing if you have a major
But again, it is ideal for home owners looking to do smaller drywall repairs.
For those DIY homeowners who insist on using quick set hot mud, I would suggest
that at a minimum they use the longer drying time muds, such as muds with set
times of at least 90 minutes. Quick set hot mud comes in powder form and is sold
in bags. It can be purchased with drying times that range from 5 minutes to 210
Additional Advantages of Quick Set
One additional benefit of quick set hot mud is that it has less shrinkage. So
when copious amounts of it may be used to do a drywall patch repair there is
less of a concern of cracking when the mud dries. Thus there is less risk of a
crack re-showing itself after the drywall repair is made.
Another key advantage of quick set hot mud is that it includes glue in its
make-up. As a result, it is ideal for binding filler materials into drywall
holes and cracks.
Disadvantages of Quick Set Hot Mud
As well as the fact that quick set hot mud sets up very quickly, it is difficult
to sand. As a result, even professional drywall contractors take steps to avoid
having to sand it. Often they use quick set hot mud for only initially taping
the drywall. With subsequent top layers of mud applied over the tape, they use
standard joint compound. This way they can easily sand the joint compound to
achieve smooth wall finishes.
How to Mix Quick Set Hot Mud for a Drywall Repair
To mix up a batch of quick set hot mud, start by pouring a little water into a
drywall mud pan.
Next slowly pour into the pan small amounts of the quick set hot mud powder to
the manufacturers recommendations. As you do so, mix the powder and water with a
small taping knife.

Once youíve mixed the powder and
water to a smooth consistency it is ready for immediate use. If you need to
modify the consistency of the mixed quick set hot mud, add the necessary water
or powder. However, any adjustment of the consistency should be done prior to
applying any of the mud. Do not keep watering down the mixture as it starts to
harden up while you are applying it to the wall(s).
It is important to note that as soon as the powder comes in contact with the
water it activates the quick set hot mud, and thus the curing clock begins. As a
result, you will want to mix up only enough mud that you think you can apply in
the prescribed drying time of the mud you purchased. Also, you want to wait to
mix up the mud until you are absolutely ready to begin applying it. For an
example, if you purchase a bag of quick set hot mud that has a drying time of 30
minutes, the clock starts ticking on its drying time as soon as you pour it into
water. So if you take 5 minutes to mix up the mud, you only have around 20 to 25
minutes to apply it.
Once youíve applied the quick set hot mud make sure to wash your drywall taping
knife and pan, as well as any other tools that came in contact with the mud,
immediately. If you donít, you will have a much harder time getting it off of
them later on.
