What is the Best Grit to Use?
When you are beginning to sand your joint compound begin using sandpaper of 120-grit. It is tempting to use a more coarse grit to finish the job fast, but anything below 100 grit is going leave some visible scratches in the joint compound.
After sanding your seams, you may opt to do a second sanding with drywall sanding papers of 150 grit.
Anything less than 100-grit is likely to take far too long to complete your first sanding. It is assumed that you are working by hand using an electric sander, a handle and drywall pole sanders.
If you’re using a drywall sander with a powerful motor it is recommended to start with a 150-grit drywall screening screen. These tools sand walls very quickly. They usually come with an attachment for vacuuming or a dust collection system that collects the dust away as you sand.
It’s essential to make use of sanding screens for better results instead of sandpaper to ensure that dust will not get trapped the wall and the head of the sander.
When you use a drywall sponge start with a grit of around 120 and gradually increase the grit. A variety of sanding sponges come with various grits on the surface. It is possible to make use of a drywall Sanding sponge to dry sand and getting into corners as well as wet sanding.

If you want to sand wet it is necessary to have an drywall sponge as well as water.
A drywall sponge is an over-sized sponge that is usually made with various grades of grits for each surface. They’re not expensive and you can find a fine sanding sponge here or in any hardware retailer. To sand drywall compound you need a medium or fine grit.
Utilizing plenty of water apply pressure to the central seams in small, circular movements, often wiping your damp sponge and changing the water.
The best thing about dry sanding is you create less mess. Dry sanding can kick up lots of dust from drywall. It’s also more suited to beginners and doesn’t require expensive equipment. It’s suitable for smaller areas and clean-up is easy.
But, wet sanding does not provide a perfect smooth surface because the sand sponge will invariably leave small ridges when you sand. Sanding with wet materials requires more time, particularly in the case of calculating the amount of time it takes for your joints in drywall to dry.
A pole sander for drywall is a nice tool to have when you’re working manually on the larger area of your project. It is usually equipped with an adjustable head mounted to a pole that is long so you can get up high on ceilings and walls. You can use the same 120 grit of sandpaper for your pole sander to begin.
Tips for Sanding
For the most perfect result, regardless of the kind of sandpaper you’re using make sure to work at a slow pace. Begin with medium-grit sandpaper, or a 120-grit/medium-grit sponge. Start with the middle of the seams, smoothing any rough areas or bumps.
Then move to the edges of the seams, smoothing the compound of drywall towards the middle of the sheets of drywall.
Select the appropriate drywall the mud. All-purpose drywall and hot mud are much more durable than topping compound, or an aluminized drywall mud such as Dap 10100 Wallboard Joint Compound.
There is an easy-sand variant of several kinds of compound. As your final coat, you can use the drywall mud in place of the all-purpose. It’s faster, easier to remove dirt and make more smooth surfaces.
Make sure your seams are properly muddied. Beware of creating “high” seams using excessive compound. This will extend the length of time needed for your wall to be smoothed to an even surface.

Make sure to make sure to feather the edges. Hard and high edges can result in you over-sanding and cause that paper fuzz’ or aren’t capable of sanding with a sharp edge which will be visible as you apply paint.
Avoid sanding cracks, gouges, or gouges. It’s tempting to use fine sandpaper, but in end, it’s more convenient to put a layer of joint compound on the deep scratches. When you attempt to sand them particularly around areas of joint compound could result in scuffing the drywall.
Fill seams that are low. Before beginning sanding, be sure to ensure that seams are filled properly and do not cause depressions – use an uncut straight edge parallel to the center of the seam, then illuminate the seam. If there is a light shining through the center the seam, then you must bulk the seam using an adhesive.
Low seams may cause you to scratch the drywall paper when sanding, or remove excessive joint compound.
