Sanding sealer should be applied after the wood has been sanded down to a bare finish, but before the topcoat (such as paint). Sanding sealer is not recommended on stained surfaces because the sanding process will scuff away the stain.
The main difference between an undercoat, sealer, and primer is that primers are applied to new surfaces, while sealers are applied before a primer or as a substitute for a primer.
There are specific sealers that you don't have to sand and you could just paint over. You need to sand down a 2K primer sealer, which is like a primer filler sealer, before paint.

A sealer is a special type of primer designed to be used with, or in place of, a primer. A sealer prevents the topcoat from soaking into the substrate, and to a degree, can create a water-resistant layer between the substrate and topcoat.
Acrylic caulk can be easily be painted, making it ideal for interior trim such as skirting boards. A silicone caulk is the best option for sealing areas prone to moisture.
During the curing process of an acrylic sealant, there is always some drying shrinkage due to the release of water. Therefore, in order to obtain the best end result, the product must be completely cured before painting. Otherwise, the paint coating may crack on the surface of the acrylic.
Sanding sealer gives an added layer of protection to the wood and creates a nice smooth finish. It can be used on stained or unstained wood. Staining or leaving the wood natural is your first step in finishing. The second step of the 3-step process is a sanding sealer to create a stronger, longer-lasting finish.
Sanding sealer can be used over many surfaces:
Raw wood: Use as the first coat when clear coating raw wood. Painted Wood: Use as the first coat when clear coating painted surfaces. Stained wood: Use as the first coat when clear coating a stained surface.
Adding sand and additives to sealer means better results for your asphalt surface. So, when choosing an asphalt contractor, make sure that this preparation is part of their process. Without this critical step, the asphalt sealer will be very slippery.
Use a brush or floor finish applicator and apply in the direction of the grain. Apply the sealer on two or three board widths at a time, being sure to keep a wet edge. Avoid over-applying or over-brushing. Let dry for 45 minutes before sanding with #120 to #150 grit or finer sandpaper.
Primers like Kilz, Fuse, and Zinnser are good for bonding very strongly. Primers can be costly, but if they are of good quality there will be no need for sanding.

Non-paintable caulk is made of clear silicone. If you apply paint directly over untreated silicone caulk, peeling will inevitably occur. Fortunately, you can paint non-paintable silicone caulk as long as you treat it with a special base primer.
