So your looking around your favorite Home Improvement store, hoping find something to patch up that hole in your wall where the bedroom door handle went thru the drywall. What you want is something that will not shrink much, so you don't have to put 5 coats on, while waiting a day for each to dry, shrink, and crack Some muds are made better for setting the tape to the wall, and can shrink to much for the two coats you have to put over it. USG has a green bucket, and many all-purpose muds are like this. USG makes many different products. Here are what you will usually find at your local Home Improvement store.
The Green Lid shrinks quite a bit. But its slippery, great for adhearing paper tape to seams and corners. A little difficult to sand. Not great for coatings after tape.
The Topping Compound with the light blue lid shrinks a little less not quite a slippery, Good for the two coats after the tape has dried. Medium sanding effort. Allow overnight at least to dry between coats longer if humid or cold.
This is my personal favorite. Sheetrock Plus 3 light weight all purpose compound. First of all it's lighter in weight than the other muds.That means its easier to carry and lighter to use. It reminds me of cake frosting. It can be used for in-bedding tape in seams and corners, as well as great for your first and finish coats. Plus3 shrinks very little. Which makes it great for touching up nail holes and nicks. Less shrinking means fuller (straighter) coats on corner bead. It is also amazing for texture. It sticks to the roller better so more goes on the ceiling than on the floor. It drys a very nice white, cleans up easily, and as mentioned earlier, shrinks less so looks almost the same the next day. It does still take at least overnight to dry.
Easy Sand 45 powder that comes in a bag is a little different product. The advantages are its sets up quickly. Which means it can be re-coated quickly. How quickly? Well the labeling gives you a pretty good idea. Easy Sand 45 Set up in approximately 45 min. So you can get taped, first coated, and finish coated in one day! Wow. That's a game changer. If you have a lot to do and it will take you longer than 45 min. to use your first batch, you may want to use Easy Sand 90, or 120. If its a really small repair you could use Easy Sand 20. But be careful this can set up rock hard by the time you get done mixing. It is pretty easy to sand and barely shrinks at all. Which means its great for larger holes and filling in large gaps before taping and coating. Mixing is pretty easy. put 1/4 or 1/2 the bag in a clean bucket and add clean cold water a little at a time and mix until you get a smooth tooth paste like consistency. And use. Be sure to clean up everything as soon as done. If you get lumps in your mix, you can add a handful or two of dried powder and remix. This usually gets most of them out. Also, if you would like it to set up a little faster, you can add warm or hot water.
Hope you find this helpful.
