When you are painting doors and cabinets, it is often better to sand before coats of latex paint. A properly finished project requires several stages of sanding and polishing. When you paint something more detailed with latex paints, such as ornate designs, sanding becomes obvious. It is possible to achieve a flat polish on a surface covering 90% of its area, but it will have to be perfected by starting from one or finishing on edge. The paint appears smoother when sanded latex is used. Often, you can have to repaint your furniture after you've sanded off the big scratches and nicks. For knowing how to sand latex paint, keep reading the following context.
You can sand latex primer once it has been applied and dried.
However, you should exercise caution when sanding to prevent damaging the underlying surface or removing the primer completely.
Start using a high-grit sandpaper such as P400 or higher to lightly abrade the area and switch to a finer grit like P800.
When finished, use a tack cloth or other lint-free cloth to wipe away any residual dust particles before applying additional coats of paint.
Use appropriate safety equipment when sanding, including gloves, safety glasses, and a face shield to protect your eyes and skin.
When Sanding Latex Paint
You can only sand cured latex, which can take several weeks to complete. When latex gets aged, it can be sanded like paint, but it will be smoother and less smooth. Several latex paint formulations can be applied in four hours, but some may need more time. The paint can be re-coated after the paint has dried for a long enough time to sand. Consider both the paint film's thickness and the hue as well. A coat of paint that has an airless sprayer is heavier and thus a longer drying time. Darker colors can take longer to dry than light colors, as well.
After you've completed the preceding coats, use fine sandpaper. The residue left from the sanding should be cleaned off. It's best to sand the flat finish with sandpaper before you apply the final coat. You should look for an even and easy flow to your project.
Some of the more popular latex paint sprayers on today's market are designed to help you get a better grip and stay safer while not getting any pasty residue between your fingers.

Option-1: Sanding Old Latex Paint
How can you sand over latex paint to achieve smooth finish? For doing this, firstly, take your wire brush and scrub the walls thoroughly to clean the loose paint.
Make a paint tray with an open bottom to catch drips and spatter.
Pull all of the cracked or peeling paint off the wall. To obtain a crisp finish, work with a sharp paint scraper. Use a grinder and sanding accessories to rid the route of rough parts.
Lay fine-grit sandpaper to wet sand latex paint over the walls to remove the paint. An oscillating sanding tool is best for shaping corners and edges. When the paint is all gone, apply the brush in a vertical stroke.

Option-2: Sanding Uncured Latex Paint
First, use a handheld orbital sander to sand down the pieces. Now, collect fine-grit sandpaper such as 180-220 grit for sand down the surface.

Generally refers to light, delicate sanding by hand using an orbital sander with a medium-grit paper.
You're not looking to wipe the paint completely off, and you are just sanding it until it's even and level. You are interested in improving the adhesion of the new paint coat.
Use a soft-bristle dusting brush to remove the dust.
Option-3: Sanding Fresh Latex Paint
For paint that hasn't hardened yet, use 120- or 150-grit sandpaper or a soft sanding sponge.
Finer-grit sandpaper is appropriate for non-sealed latex paint, which takes at least 30 days to harden, and paint scratches can occur with the next-higher grits.
Sand with a gentle touch. If the paint is colored, the sandpaper can pick up some of the colors. This is acceptable as long as the paint is not sanded off.
Before applying the next coat, use a moist, not-soaking wet cloth to clean away the sanding residue.
