Why Wet Sand? The purpose of wet sanding is to get an even surface finish after dry sanding. Dry sanding shapes the surface, while wet sanding removes the large scratches left by dry sanding.
Yes, wet sanding primer before painting is generally recommended. Here are the benefits of wet sanding primer:
Sanding after applying primer will help you keep the surface as smooth and flat as possible, eliminating any leftover bumps, dents, brush marks, etc. And that sometimes happens if you didn't' check it well before priming. Consequently, it'll help you to achieve a bright final coat and that's not dull.
``Wet on wet'' is a technique rather than a type of paint. It is often used on the final primer or colour coats to achieve a high build smooth finish and minimise polishing or sanding. One coat of paint is sprayed, then the panel is immediately sprayed again while the first coat is still wet.
What Happens If You Skip Sanding? If you don't sand your car before painting, you'll end up with a flawed surface. At a distance, the car might look nice enough for photos. But the uneven, rough top coat will tell a different story up close.
Once you've completed your last coat of primer, you should go ahead and sand before applying your first coat of base color. However, there is no reason at all to sand between coats of primer. It will only add more work to your plate with no visible benefits.
Excellent final appearance as a wet-on-wet that is as good as a sanded primer meaning no compromise in quality. Strong application characteristics – good flow, very smooth film and good sag resistance even on large areas. Can be left up to 5 days before sanding for topcoat application.
Painting over primer that hasn't fully dried can lead to problems like poor adhesion, uneven coverage, and a compromised paint job. Ensuring the primer is completely dry helps achieve a durable and attractive finish.
If you are looking for a better overall finish the smoother the better which can at times require sanding the wood with a primer on it with up to a 600 grit sand paper.
You will want to use 2-3 coats of primer to ensure there is a good bond between the new paint and the wall, and also to cover up any previous colors, especially if they are red, orange, or a strange outdated color. In short, you will typically need 2 coats of primer for most painting projects.
Can you use Zinsser without sanding? The beauty of many Zinsser primers, especially the Bulls Eye 1-2-3, is their excellent adhesion, eliminating the need for sanding even on glossy surfaces.
Most latex primers dry to the touch in 30 minutes to one hour. But for best results, don't paint until the primer completely dries—which can take up to 3 hours, depending on temperature and humidity.
Sand Primer
Finish off by lightly sanding your primed wall with a fine-grit sandpaper, this will help smooth your surface for painting.
Wet sanding requires specific waterproof sandpaper and is almost always done by hand. Because wet sanding is a finishing process, you'll likely use high-grit sandpaper, from 1000 grit to 3000 grit and above. Compare this to dry sanding, which typically begins with 600- or 800-grit sandpaper.
The wet on wet technique involves applying wet paint onto wet paper. It allows colours to blend and bleed into each other on the wet surface, creating soft and diffused edges. The wet-on-wet technique is excellent for creating smooth gradients, soft backgrounds, and atmospheric effects.
Knowing this little trick will make your watercolors so much more vibrant and saturated with the color! Watercolors need water to work and the same goes with your watercolor pans!
If it is 15% moisture content or below, it is ok to paint. If it is above 15%, it is not ok to paint and you should wait until the moisture content meets the 15% or less threshold prior to proceeding with your project. That is the science.
DRY & RECOAT
Dries to touch in 20-30 minutes and is fully dry in 1 hour. When dry, surface can be immediately recoated, top coated, or wet sanded. For best results, allow to Primer to dry for 1 hour before dry sanding.

Not every type of paint is a good candidate for wet sanding, and you should almost never wet sand factory clear coat paint. Most of the time when we're talking about wet sanding, it's in the context of sanding fresh, custom paint — not the factory paint on a daily driver.
Yes! I think I'd rather paint 10 coats than do one round of sanding. These primers can be found at any hardware store. Look for something that states that it will allow you to paint over glossy surfaces without de-glossing or sanding.
Darker colors will make it hard for a new paint color to be properly displayed. Although each surface and base color will be different, it's a safe bet that two coats of primer will achieve any priming goals you have.
