180 to 220 Grit Sandpaper: Finer grit sandpaper is great for removing the scratches left by coarser grits on unfinished wood and for lightly sanding between coats of paint. 320 to 400 Grit Sandpaper: Very fine grit sandpaper is used for light sanding between coats of finish and to sand metal and other hard surfaces.
240 Grit With its very fine texture, 240 grit sandpaper is ideal for sanding finishes between coats. It's gentle enough to smooth down dried layers without damaging them, giving a polished look while maintaining the integrity of each layer. It's also effective for finishing touches on bare wood.
You have two options for sanding: you can start with the courser grit sandpaper (between 600-800 grit), or you can go straight to the fine-grit sandpaper (between 1,200-2,000 grit). Tip: For optimum results, you will want to start with a courser grit, and finish with the fine grit.
Use fine grit sandpaper, between 150 and 180 grit, to achieve the desired results.
Extra fine grit sandpaper (320+): Keep this on-hand for sanding between coats of paint or finish.
Generally, 180-220 grit is a good choice for sanding between coats. These extra fine grits do a great job on most interior walls. Grits of 240 and higher are best suited for projects where polishing is involved.
WHAT IS THE IDEAL GRIT TO SAND CABINETS BEFORE PAINTING? To remove old paint or finishes, you want to begin with a coarse grit, around 80 to 120. You'll go from coarse grits to finer ones, scrapping off the old layer and smoothening the surface before painting. Finish with a finer grit, anywhere from 220 to 320.
Knock down any ridges or significantly imperfect areas through sanding, which should help you apply the next coat of mud smoothly. If your first coat of mud is pretty smooth after it dries, a quick sanding is all you'll need. Don't forget to wipe away any dust after each sanding process.
After the primer dries, lightly sand away bumps and ridges using very fine grit sandpaper folded into quarters. When the grit of one section of sandpaper becomes covered with dust, switch to an unused section and continue. Wipe the wall clean with a damp towel or sponge and allow it to dry before painting.
For heavy sanding and stripping, you need coarse sandpaper grit measuring 40- to 60-grit; for smoothing surfaces and removing small imperfections, choose medium sandpaper from 80- to 120-grit sandpaper. To finish surfaces smoothly, use a super fine sandpaper with 400- to 600-grit.
Conclusion. Sanding between coats of paint is a valuable step in the painting process that can greatly enhance the quality and longevity of your paint job. It helps to create a smoother and more professional-looking finish by eliminating imperfections and ensuring better paint adhesion.
Wipe With a Clean White Cloth
Use a clean cloth to wipe the rest of the dust from the surface of your wood after using specialized equipment. This helps you pick up any extra dust particles to ensure the wood is clean and ready for stain or paint. Use a white cloth so you can see how much dust you pick up.
The main reason people sand between coats of paint is to achieve a perfect, silky smooth layer of paint. For most drywall interior painting projects, sanding is not necessary.
180 - 220 Grit: Fine. 180 – 220 grit is primarily used for the sanding finish or to sand in-between coats. It is also great for distressing! There are instances where you can use 180 to 220-grit to rough up a piece in preparation for paint, but you do not typically use these grits until after your first coat.
Base Coat
In this case, sanding between every single coat of the base coat layer, or even once it's done is unnecessary. As we mentioned earlier, any use of sanding along the base coat should only be done in the case of there being any damage, debris, or imperfections in the paint.
Moving on to when you should sand between coats in interior painting projects, let's explore some exceptions and special considerations. Key Takeaway: Sanding between coats of semi-gloss paint is essential for proper adhesion and a smooth finish.

Can you paint over primer without sanding the car? Technically, yes, you can do that. Some circumstances don't require sanding the existing paint and primer before repainting.

Too much sanding will cause damage to the paper face on the drywall.
Drying Time and Sanding
Once all coats are applied, give the cabinets ample time to cure before reattaching hardware or using them regularly. Light sanding (with a high grit sandpaper) between coats can also be done if necessary, to remove any imperfections and create a super smooth finish.
Liquid sandpaper, a.k.a. deglosser, is a chemical that can be used to rough up existing paint on walls and other surfaces by removing the gloss, making it possible to paint over what's left on the wall after use. This is good for hard to reach places or an object that you may feel would be awkward to sand.
For "hard to stain" woods, finish sanding with 120 grit will usually accommodate the problem. For finish sanding on most furniture hardwoods (e.g., cherry and mahogany) use 180 grit or 220 grit. The use of grits up to 600 is certainly allowed but is not standard practice.
