The joint compound, also known as drywall mud, is a gypsum-based paste used to finish drywall joints and corners in new drywall installations. It is also useful for repairing cracks and holes in existing drywall. Drywall mud comes in various types and brands, such as hot mud, durabond, and other materials.
To determine the best mud for an application, consider the type of joint compound used. Setting-type joint compounds, such as ProForm® Quick-Set Lite™ Setting Compound, are recommended for all exterior joint treatment and skim coat applications. Ready mix products are not approved for exterior use.
Exterior grade paintable caulk can be used to hide seams and prevent moisture/expansion problems. Any drywall mud (joint compound) will work for most drywall jobs, but some muds are better than others for specific phases of finishing. Some popular options include DAP’s DryDex 32 oz. Premium Lightweight Low Dust Joint Compound, DRICORE’s 1 qt. PatchPro Premixed Patching Compound, and Plaster of Paris.
When choosing a drywall mud, consider its versatility. All-purpose, lightweight, tapering, topping, ready-mixed, and dry compounds are suitable for exterior construction projects. To prevent mud spatter on exterior walls and windows, cover the soil with landscape fabric, gravel, organic mulches, or low-growing plants.
In summary, the choice of drywall mud depends on the specific needs and requirements of the project. A versatile drywall mud is essential for any project, as it ensures durability and longevity.

How do you waterproof drywall mud?
Waterproofing drywall is a common method used by most paint manufacturers to prevent mold and mildew growth. To waterproof drywall, clean any dust off the surface using a wet dry vac or microfiber cloth, avoid using water or cleaning supplies, and apply the primer in a thin, even layer using a paint roller brush. For corners and along baseboards, use a smaller paint brush. This quick and easy process ensures a secure and long-lasting waterproofing solution.
What is the best mud for final coat?
Topping compound is the best mud for final coats of drywall joints, providing a strong bond and smooth application. It is typically sold in dry powder, which can be mixed with water, making it less convenient than premixed compound. Topping compound can also be purchased in pre-mixed boxes or buckets. It is not recommended for embedding joint tape, the first coat on most drywall joints. When applied properly, it reduces sanding time compared to lightweight compounds like all-purpose mud.
Taping compound is ideal for embedding joint tape and covering plaster cracks, but it dries harder and is more difficult to sand than all-purpose and topping compounds. It is also the best mud option for laminating drywall panels in multi-layer partitions and ceilings, as it offers superior bonding and crack-resistance. Overall, taping compound is the best choice for drywall joint finishing.
Is there an exterior drywall mud?
It is recommended that Sheetrock® Brand Setting-Type Joint Compounds (Durabond® and Easy Sand™) be used for the treatment of joints in exterior gypsum ceiling boards.

Can you use joint compound outside?
For painted surfaces, use paper-faced, mold- and moisture-resistant gypsum board like XP Fire-Shield Gypsum Board. Glass-mat faced gypsum panels like Gold Bond® eXP® Sheathing or Gold Bond® eXP® Interior Extreme® Gypsum Board require an additional skim-coat of joint compound for a smooth, paintable surface. Setting-type joint compounds like ProForm® Quick-Set Lite™ Setting Compound are recommended for all exterior joint treatment and skim coat applications.
Ready mix products are not approved for exterior use. Direct-applied Exterior Finish Systems (DEFS) can be applied to soffit substrates like XP® gypsum boards, eXP® gypsum panels, or PermaBASE® cement boards. Consult the DEFS manufacturer for approved substrates and application methods. For fire-rated floor- or roof-ceiling assemblies, verify that the soffit material is listed in the rated UL design.

What is the difference between joint compound and drywall mud?
Joint compound, also known as drywall compound, is a white powder made from gypsum dust and water, used to create a paste-like texture on drywall. It is applied to create a seamless base for paint on walls and ceilings, effectively eliminating blemishes like fasteners, damage, or drywall tape. It is used to finish gypsum panel joints filled with paper or fiber joint tape, corner bead, trim, fasteners, and skim coat. It is also used for patching holes, bumps, tears, and minor damage to existing walls.
In North America, troweling joint mud on gypsum panels is a standard construction technique before painting. Joint compound type and formula selection form part of a drywall system, which can be finished from level 0 to level 5.
📹 DON’T USE DRYWALL BUCKET MUD!! Use this instead…(Quick Setting Joint Compound / “Hot Mud”)

Yep, agree with what you are saying. But as a handyman/DIY person without the training or expertise of a professional plasterer I just can’t get the plaster on fast enough to be able to use hot mud and end up either with a mess of a job or wasted plaster that goes off before I can get it up, or both. As a DIY person I choose pre-mix every time.
I have used pre-mixed compound for years. It does take a bit to dry, but I have never had a problem with it. I have used “hot mud” on rare occasions when I need to do several coats in a single day. However, most of my spackling is done via pre-mix. I believe that pre-mixed compound is the way to go about 80% of the time.
Half dozen one way 6 the other…. I get a good 5yrs+ out of joint compound in a bucket (albeit very small bucket) for patch jobs. I’m not putting up new walls with this after all, but patching cracks, holes, and other misc stuff. I can also get between 1 to 5yrs out of Hot Mud stored in a bag (depends on the humidity where I live – when in Houston 1yr and that stuff is toast – in California I can get 5yrs out of it.) As for the getting mold in the bucket, skim the top and toss it out. The stuff below is good, the only thing you really need to worry about is if it gets to dry. Don’t add water to the bucket but get some joint compound out, and add a tiny bit of water to it to make it workable again.
God damn, I have been around some old timers that tape and mud. They mix it so thin I’m not even sure how they keep it on the wall, they use mop and run around the corners second guy goes with the tape. After they put 3 coats they use do a 4 coat very very thin. I never ever had to sand after these guys. Now 45 or 90 is excellent for fill rookies shouldn’t mess with it. I take 45 and mix it with red cap bucket It. I find red cap bucket much, much better then anything else in the market. Now I start liking plaster better. $50 per sheet labor and material room done in one day.
Hi there, great vid… Could you help me? I want to tape and joint a ceiling inside a container home… The ceiling flexes by almost an inch along a 30 foot span when I’m walking on the roof for maintenance… Is there a special flexible mud I can use along with tape in the joins that will avoid cracking down the line. Thanks
This drying of the bucket is good as it makes you complete the job right now instead of messing around with a little here, a little more next weekend…maybe. And if you do an ugly job the fixer you hire will make more money taking it off (takes a wile to wet and scrape off) then finding the drywall you broke but left and tried to hide. Now if you hired an equally incompetent sheerokero first from craigslist who gives ‘free’ estimates, it will cost you even more. Buy cheap, buy thrice! Dont let me stop you though, its your money. XD
The problem is that hot mud is pretty much made for professionals someone with the skills to work with mud fast.. the typical home owner isn’t that fast nor want the mix mud every time to patch a small hole.. also in the commercial construction field 90% of the mud is premix because time is money… a permix mud is cheaper so when buying 200-300 buckets at a time.. great article tho
