Hot mud basics - Drywall Instruction

[@weekendwarrior3420]

Hot mud is beautiful. Anyone who worked with a mortar before will not be afraid of hot mud. The main advantages are - it shrinks very little and hardens quickly, allowing to finish with regular mud on top the same day. And you really can't avoid it where you need a thick layer. But don't spread it thin - it may dry before hardening and then it won't hold. It's a chemical reaction where water combines and becomes whole with the powder. If it evaporates before that, this won't happen. I'd avoid putting a fan on hot mud for this reason.

Why in the world do you have two butt joints lined up?

[@ndmx1000]

Why did you not stagger the drywall?

[@drywallinstruction1766]

That's actually a great question. You're the first to comment on that. In the process of putting together a recording room I just threw some rock up to be a backdrop never intending to tape it. You're right, you always stagger seams.

[@Matty-Mat79]

Butt boards are available

[@Rick-the-Swift]

It's all about the application. general rule of thumb is to stagger the joints but by no means the golden rule. Sometimes not staggering the joints gets the job done more efficiently with less actual joints. if the framing and the hang are solid, it usually won't matter in the end, and the extra strength that would come from staggering would be nominal and likely not necessary.

[@aaronmackay6123]

I couldn't stop looking at that. I'm just here to brush up because I got a time restriction on my job this time.

[@daveyboymusic6277]

@@Rick-the-Swift The problem with not staggering the boards is that you have 4 intersecting points instead of 2, which means it could crack more easily. By staggering the boards, you are interlocking and creating a stronger foundation. I've been taping drywall for 36 years, and I've never seen anyone, including multiple pro companies, not stagger the boarding.

This is just a tip from someone who's done this for 30 years if your not really good already and if your watching this your probably not STAY AWAY FROM HOT MUD!

Or simply make small batches until you get comfortable. You may toss a couple but tool get it...

First time doing this, I used 45 minute. Simply make small batches until you get comfortable. You may toss a couple but you'll get it... just think of it as a learning process. Remember, life's a joke we all die in the end. Your project may seem daunting but it can simply be scrapped and started over. Another reason for another case of beer. 🍻 Lastly, dude you're so eloquent in your production and delivery, I got the Silence of the Lamb vibe. Emmy award for production and breakdown. 😊 Thanks

did u quit making videos?i think ur videos have helped me the most,I'm a painter/turned into drywall guy,I usually can pick up any trade pretty fast and get good at it I'm very meticulous,anyway I love ur videos and I think u should make more!U should make some on how to texture different styles of texture...have a great night!

[@drywallinstruction1766]

It's great to hear that the videos helped. I have chosen to put the texture videos on a subscription side. For a small fee you can learn most any texture @ Drywallinstruction.com.

I'm painter..i use use 5 min at my hospital for all my repairs...if you know how to finish and pull you final coat tight...it usually comes out really smooth not Much sanding required if at all...sanding at a hospital is a mess...gotta have a vacuum setup or hang plastic to block off area, turn off smoke dectors...etc...i learned early on working there that I must learn how to finish without having to sand...I also have a ram air blower that I set towards the patches.they dry/cure same day..and I can usually at least get them primed same day...

[@dougpeters1625]

Possibly the best video I have seen on this subject. You answered every single one of my questions. Thanks!

[@drywallinstruction1766]

Thanks for the feedback!

[@Beyond_Sight_Media]

Can you hot mud over the top of paint? We have a ton of skip trowel texture that we want to smooth out so we can have normal texture like orange peel. I see you are in the NW. Do you have contact info?

[@drywallinstruction1766]

You can hot mud over paint but it's much more efficient to use topping and let it dry if you're floating a large area.

[@markchadwick77]

I like your videos. Here's a suggestion. When you mention another video, include the link to that video in the description. Otherwise, it can be hard for me to search for it. Furthermore (since I'm a KZbin creator), I know that your videos will rank much higher if someone views a subsequent video. If you have time, go back to videos you have already created, and add the links.

[@drywallinstruction1766]

Thanks Mark for the feedback, I'll get to work on this!

[@Matty-Mat79]

They use butt boards now so you can put joints anywhere now a days

What instructions?

[@agontop1]

Didn’t know hot mud is that versatile in the job. Loved listening to the knowledge you were sharing. Thank you

[@drywallinstruction1766]

You're welcome! Good luck to you!

[@silekiernanphotography]

When buying "hot mud" do I look for joint compound? Is "hot mud" slang for joint compound?

[@drywallinstruction1766]

Hot mud is a powder that when mixed with water sets up quickly. It's sold in a bag.

[@silekiernanphotography]

@@drywallinstruction1766 Thank you! There is nothing in the hardware stores by that name (hot mud) and I can only assume that it is joint compound. Hopefully that will work.

[@drywallinstruction1766]

@@silekiernanphotography Sometimes you can find 5 minute hot mud at Lowes or Home Depot. Otherwise you'll find it at a drywall supply.

[@silekiernanphotography]

@@drywallinstruction1766 I'll keep looking, I tried both Lowes and Home Depot and nothing called "hot mud." I will try next time I am back there. Thank you.

[@seandaliege]

What do you think about using spray foam in the place of hot mud for filling larger gaps?

[@drywallinstruction1766]

My experience with spray foam is that it's a mess, hard to control, and often creates more work. I've never heard of it used for this application.

[@seandaliege]

@@drywallinstruction1766 Thanks for the reply! I got the idea from another popular KZbinr. And since I posted this comment I used the foam on the ceiling gaps and hot mud on the wall's side corners. The mud is easier to work with but the foam doesn't sag and fall out on the ceiling while drying as much so I tried it out there. It cuts super clean IF you use the right serrated blade. I'll let you know how it tapes and finishes if you'd like? PS this is my first time doing drywall and your videos are a huge help.

[@drywallinstruction1766]

@@seandaliege Great to hear it!

[@petergriffin1546]

Before priming and repairing pin holes and trowel marks in new plaster that has dried for 30 days... can you use hot mud? or is there a better alternative?

[@donnorton8052]

Try usg sheet rock easy sand 20 min it does sand pretty easy

[@krehbein]

Is usg easy sand 20 considered hot mud, and do you consider it harder to sand despite its name?

[@drywallinstruction1766]

It is hot mud. My personal opinion is that it was never intended to be sanded. Once dried and cured it is a very hard product. Hot mud is the best thing ever for doing repairs, you can tape, coat , and use a wet rag to blend into existing texture and then texture immediately. People also use it to do a first or 2nd coat just to speed up the process. Good luck to you!

[@krehbein]

Interesting comment about it not intended to be sanded. I have noticed when I use it for projects around the house it takes quite a bit of work sanding it if I'm not careful feathering edges and avoiding mounds. I'll have to try the lightweight mud on my next project. Also, can you use the wet rag technique only when your going to texture? Everything in this area is smooth only. What kind of rag do you use so you don't leave lines? Thanks and appreciate your videos.

[@drywallinstruction1766]

You can get it very smooth with a painter's rag.

[@DUDE72341]

Found out the hard way you cannot sand hot mud 220 grit will not knock it down..pain in the butt

Hey great video. Next video should be how to make an arc wall. The one in the background. How do you drywall like that? Need to do some research.

[@larsturner310]

Thanks for the helpful information.

[@drywallinstruction1766]

[@rickeykeeton4770]

When you use hot mud, or regular mud, do you blend each coat from first to last? I seem to really have a problem when using hot mud with the webbed tape. Another thing, I noticed in my 90 minute mud, directions say nit to blend with any other type mud. I have used hot mud for first and second coat then finished with regular several times with no problem I am aware of.

[@EngineerMikeF]

Web tape is ok for tailored edge jobs but bunk for butt joints. I switched back to paper for that reason. And all my first coat is hot mud, especially filling gaps where hot mud is ideal. A 40yr pro called it liquid wallboard. Because it hardens vs drying, gap filling won't shrink or drift over time as ambient moisture fluctuates where drying mud can creep over time. I pre full every butt, taper & corner gap w/1 pad of hot mud regardless and set paper in hot mud. For exterior I only use hot mud throughout for moisture resistance.

[@rickeykeeton4770]

@@EngineerMikeF You use hot mud for exterior?

[@EngineerMikeF]

@@rickeykeeton4770 ​@rickeykeeton4770 Not for full exterior exposure, but under cover. I used it on my roofed over, outdoor kitchen on green board. Today I'd use the moisture, mold & mildew resistant board plus hot mud in that application

[@rdmadding9952]

Thanks for sharing your time and knowledge - very helpful! I thought you mentioned something about taping with hot mud...did I hear you correctly? Is this something you practice and recommend? My upcoming project has somewhat of a time constraint on it so an overnight option with mixed taping mud would be my second choice. But if that's the only way, then so be it. Your videos are becoming my go to source as I learn more about working with drywall. Thanks, again!

[@drywallinstruction1766]

You're very welcome, I'm glad you're enjoying the videos! You absolutely can tape with hot mud but you need to remember the time required to mix your mud and be sure not to plan on sanding your hot mud. The benefit of premixed mud is that it's ready to go and easier to sand. On repairs and very small projects I always tape and coat with hot mud but I always wipe with a wet rag instead of sand. Remember that when using pre-mixed mud that you can coat immediately after you put your tape on, it doesn't have to dry. Check out what's going on @ Drywallinstruction.com!

[@rdmadding9952]

Got it, thanks. This is a repair (cracked tape on a smooth ceiling) with a new coat of paint over the entire ceiling afterwards. I might try the hot mud method; the work is being done is in a fancy dining room so simple/minimal clean-up with wet rag smoothing is attractive. Thanks for the reminder on top coating immediately after taping with pre-mixed (then sand when cured - I still need to watch your sanding videos). Definite time saver over my previous thinking. BTW - You mentioned in one of your other videos that working with drywall can be fun and enjoyable - I'm beginning to agree thanks to you! I'll keep my eyes open on the website. I appreciate your timely reply!

Is there a difference between 45 hotmud vs taping mud? as in, which one is best/most ideal if one isnt worried about time?

[@blazeofficial1591]

It depends what your doing, if your taping then taping mud would be your best bet.

[@kennethwilliams2738]

Also depends on what kind of tape your using. For paper tape, use AP, if your using mesh tape, that has to be bedded in with setting compound aka hot mud.
