Firstly I am not a drywaller, and getting smooth drywall joints can be a challenge for some DIYers. I have put together some information to try to help you on your way to smother drywall joints .
Drywall joints can be some of the trickier parts of the drywall process. Although it’s not much different than the procedures for tackling the other parts of your wall, smooth drywall joints can be more challenging. When sanding, priming and painting, the last thing you want to do is be faced with irritating signs of where the joints begin and end.
Here are a few tips on making those drywall joints smoother :
You can always change the amount and size of the joint compound on your new drywall. After the initial coating of drywall joint compound has dried, you can increase the size of the trowel you use as you continue the process. Cover the area using a 6-inch trowel, let dry and then proceed with a 10-inch trowel, allowing that to dry as well.
Still, not satisfied with the outcome? Take it up a notch and continue to increase the size of the trowel up to 12-inch to make for a smoother and more seamless drywall joint. Just make certain to let it dry before increasing the size of the trowel and applying more drywall joint compound.
Some professionals can create the smoothest drywall joints simply because they have probably been doing this since they were teenagers. Many have learned at their father’s or uncle’s side and are proficient in creating smooth and seamless drywall joints. For the rest of us, as do-it-yourselfers, there’s sandpaper. Not just any sandpaper, though, but drywall sandpaper.
Sanding to create smooth Drywall joints
The more you sand down those drywall joints, the smoother they are and the easier they are to prime and paint. The end result will be a brand new room. When coming to the edges of your drywall joint compound, use a lighter touch so that you get a seamless finish without disturbing the paper edges too much.
Mesh tape when first starting out may be the best answer for finishing the joints of your drywall. For the most part, it comes as self-adhesive and can go right on the joint itself.
Make sure you have enough joint compound to cover the seam and then when dry, get ready to sand away. Usually, using the compound three times in a crisscross method does the trick. Feather out the edges and you should be all set to go.
One of the best tips, however, is to get plenty of time in watching videos on how to smooth out drywall joints. There’s nothing like watching someone do it over and over again to allow you to get a good feel for how you can “get smooth drywall joints yourself.”
Once you’ve taken on putting up drywall, the tips and tricks will come to you with ease. You’ll get to see which stroke works for you, how many, and exactly how to feather the ends of the seams just right. The fact that you’ve taken this on by doing it yourself means you already have enough confidence to make it work.
What Type of Sandpaper Do You Use on Drywall?
If you are preparing to do a drywall project, then you need to know what materials and supplies you will need. You may think it’s a simple matter of having some joint compound, a little sandpaper and off you go. This is not the case, however. When you are in the middle of doing a drywall project, you don’t want to be in the position where you are ready to sand down your joints and rough patches and all of a sudden find you have the wrong type of sandpaper.
What’s so special about sandpaper? Well, the type of sandpaper you use could make or break your drywall project. Why is that? Well, for starters, your finished project, which will be the painted walls, will only be as good as the sanding you do to get them perfect. Without the right materials throughout the project, you risk having lumps and bumps. What is the point of having new walls if they are going to resemble old walls? Your drywall is only as good as your sandpaper.
Give Your Walls a Once-Over sanding
You can use a pole sander with 120-grit sandpaper. In this way you will have a better reach and provide more coverage to the walls. Giving it a once-over will set the foundation of the sanding yet to come.
Apply even pressure as you go along the wall, gently guiding it over the joint seams until you have a smoother appearance on the surface of the drywall.
You can use the pole as a guide to making your walls smooth by twisting the handle. The ball joint on the sander will maneuver so that it reaches those tough nooks and crannies.
Hand Sanding for smooth drywall joints
When you hand sand, plan to use a hand sander with 150-grit sandpaper. However, if you are using just the sandpaper, then fold it for ease of use. When it comes to the fine details and the tough-to-reach spots like corners, you might want to use hand sanding techniques for better effect. Use circular motions and a medium weight pressure to get those scratches and minor nuances smoothed out.
Some do-it-yourselfers prefer to use a wet sanding technique using a wet sponge. If you do this, make certain to keep rinsing the sponge and keep it clean.
Shapes and Sizes of sandpaper
You can buy sandpaper in different grades such as garnet paper, aluminum-oxide or silicon-carbide (which is typically used for the wet/dry situations).
Depending on what you want to achieve, there are different grits to sandpaper – grits meaning the amount of abrasive quality it contains. Typically, for a nice, soft, smooth finish, grits that are either 120 or 150 are probably best for your drywall project. You might want to start with 120 and give it a final once-over with 150.
Once you choose the right sandpaper for your particular project, the rest can be smooth sanding all the way. Here are a few reference articles to help you out .

How to Finish Drywall: 18 Steps to Smooth Joints
There are few home improvement tasks greeted with more dread than finishing drywall. If you’re like most people, you hope that you’ve already done your last finishing job. Unfortunately, if you enjoy working on your home, you are bound to be confronted by this task again. So it’s worth your while to check out the tips and techniques we discuss here.
The selection of tools we show here are not the only ones that work. Some people prefer wider drywall knives. Regardless of your preference, be sure that all the knife blades are very flexible. Holding the handle and the blade, you should be able to easily flex the blade between your thumbs.
Your selection of compound is just as important as your selection of tools. Compound is available in two types. One is called a setting compound and cures by a chemical reaction. The other is a drying compound that hardens through evaporation. The latter is available in a powder or ready-mixed version, but for most people the ready-mixed product is far more convenient. This is what we used.
