Everything About Mud

 

There are many different brands of joint compound but there are really only 3 types.

1.  All purpose: Used for taping and texture. Can be used for coating, but shrinks more and sands harder.

2.  Topping: Used for 1st and 2nd coats.  It Shrinks less and sands much easier than all purpose.

3.  Quick set or accelerated (Hot Mud): This comes in bags. It's powder that you mix with water.  Ranges in drying time from 5 minutes to 210 minutes. Be carefull, once it starts setting up, there's no stopping it,  and it is very hard to sand.

Mud comes in pales, bags, buckets and boxes.

 

HOW TO MIX REGULAR MUD

 

Open up your box of mud, then open the inside plastic bag. Pull the plastic around the outside of the box.

 

 

 

Hold the box over your empty bucket corner side down. Slowly shake the box until the mud starts coming out. Hold the outside plastic bag so when the mud falls into the bucket you are still holding the empty bag. It takes a little practice..You can do it..

 

 

The mud is too thick right now to do anything. Pour in a cup or two of water depending on how thin you want it.. There are 2 ways to mix the mud. You can use the stomper (Mud masher) or you can use an electric drill with a mud paddle. Mix it up until it is smooth and lump free.

 

 

 

If you're using a new bucket of mud (Not a box), you might want to remove a scoop or 2 of mud so there will be room for your water, then mix. Put the extra mud on the lid. After you use up some mud, you can throw the stuff from the lid back in the mix.

 

 

HOW TO SAVE YOUR MUD ( TOP IT OFF )

 

By topping off your mud you are creating a water seal to keep everything fresh. Once your mud is topped off you can leave it overnight or leave it for 2 weeks.  First use your hand and wipe down the side of the bucket. Now pour in a couple inches of water and scrub down the sides. I always leave my stomper right in the bucket and I scrub down the handle.

 

  

 

That's It !!

 

Now we have a nice bucket of mud, topped off and ready to use again. It's not going to dry out and we didn't even have to wash the stomper. When you're ready to use it again just dump off the excess water and you're good to go..

 

 

 

HOW TO MIX HOT MUD

 

Pour a little water in your drywall pan 1st. Now slowly pour in a small amount of hot mud powder. Keep stirring up the mud using a  6 inch drywall knife. This takes a little practice. If it gets too thick ad a little water, too thin ad a little powder. When you get it nice and smooth you are ready to do some coating. In this example, I'm using "20 minute" mud which means it starts setting up in 15-20 minutes. If you use 5 min or 20 min, don't waste too much time mixing it up. You can buy all different speeds (drying time) of hot mud, any where from 5 to 210 minute.

 

 

 

HOW TO MIX A WHOLE BUCKET OF QUICKSET OR ACCELERATED JOINT COMPOUND (HOT MUD) 

 

 Hot mud is a powder that when combined with water has a chemical reaction that causes a very fast dry time.

What I'm showing here is how to mix a 5 gallon bucket full

 

What you will need

 Hot mud : You can buy many various drying times from 5 minutes to 210 minutes.

I Only use Sheet rock Brand Hot Mud.

I do not recommend trying to mix a whole bucket of 5 or 20 minute mud.

You will need about a bag and a half for a full bucket of mud.

You will need a drill and a paddle

A empty bucket and a bucket full of water

 

 

Step 1: Pour water into bucket

 

Use the paddle as your reference. If you fill the bucket just to the top of the paddle, that will yield a full bucket of mud

 

 

Step 2: Add powder

 

I'm using 210 minute mud, that gives me plenty of time to work but I also know for sure it will be dry the next day.

Start by tearing the corner the corner off of the bag, pour some powder in.

You don't want to dump it all in at once or you will end up with lumpy mud.

 

 

 

Step 3: Mix

 

Straddle the bucket with your feet, slowly start to mix. A variable speed drill helps. You don't want to just hit the trigger full force or you will have water and mud flying everywhere. Mix it up a little, add more powder, mix it, add more powder.

Once you have dumped the whole 1st bag in you will see it's still pretty soupy.

Open a new bag and slowly add more powder until you get the right consistency

 

 

Be careful hot mud is tricky

 

By using 210 or even 90 minute mud you can probably get by with using a bucket full, mix up another bucket and you should be fine.

The problem is that this is all a chemical deal.

 Say you mix up a bucket of 45 minute mud. You start coating something, you go pretty fast, now you need another bucket full so you ad more water, powder and mix up more.

That 1st batch is already starting to set up so any remnants of the 1st batch, in the bucket, on your paddle and on your tools causes the new batch to set up as well. I would recommend after every bucket full you wash everything. Tools, buckets, paddle, start out fresh with a new clean bucket and clean water.

 

Wash your tools right away

This stuff sets up like cement. If you don't get everything clean as soon as you're done you never will. If you let hot mud set up on your paddle you might as well throw it away
