What is HOT MUD?
To an experienced Drywaller, hot mud is magic. What hot mud really is, is it is a fast setting joint compound that comes in numbered working times. For example you can buy a hot mud in five minute, 20 minute, 45 and 90 minute. These times are the working time before it starts setting up meaning once you start mixing it with a 20 minute hot mud you have 20 minutes until it starts to thicken up and become unusable.
We call it hot mud because it begins to set up and harden through a chemical exothermic reaction which creates a little bit of heat in the process.
Experienced drywall repair guys call it magic because it can greatly speed up your workflow when doing things like drywall repairs. If you learn how to spread the mud quickly and efficiently, you can complete multiple drywall repairs in one or two hours. With normal air drying joint compound the same process could take days.
I will cover this specific type of drywall mud, much more in one of the lessons in the classroom.
