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.

How long to wait to sand latex paint?
You should need to wait for latex paint sanding depending on several factors, such as temperature and humidity. But, dark colors take longer to dry because of their greater concentration of slow-drying pigments. Painting takes place over two days, whether you like it or not.
Rushing the process of sanding would cause your painting to fail. When painting, you should allow the paint to dry for at least twelve to twenty-four hours, but it may vary depending on the paint.

Latex Paint Sandpaper – Know the Secrets!
How can you sand latex paint by using grit sandpaper? Latex paint needs sanding with 180-grit to 220-grit sandpaper. Unfinished wood can benefit from the finest grit, which will remove scratches made by coarser grains, and painting does not require it to be completely smooth to be done with something in between coats. When the paper becomes blocked, use a coarser grit. 220-grit sandpaper works well for roughing up the finish. This is suitable for do-it-it-yourself endeavors.
