Most modern clear coats are urethanes and will require you to sand it if you place any paints (including primers) over it since you will need a mechanical bond.
Wait for 24 hours for the sealant to fully dry before applying paint. The product can be painted over with water-based and synthetic paints. Note: Before application, test the sealant's compatibility with the paint you are going to use.
There are a few ways to do this, but we choose to use an oil-based primer to prepare our varnished wood for new paint. The oil-based primer will stick to varnished or sealed wood. And then you can paint over it with latex paint.
The first coat of finish, whether a purpose-made sealer or just a thinned coat of the final finish, generally leaves a rough surface with raised grain embedded in the finish. At this stage you aren't flattening the surface, just smoothing it, so there is no need to use a sanding block.
Not sanding between coats of paint or varnish can result in a rough or uneven surface texture, visible imperfections like brush marks or drips, and reduced adhesion between layers. Sanding between coats smooths the surface, improves finish adhesion, and enhances the overall quality of the final coat.
Sanding is often a crucial step for ensuring that your surface is ready to be painted. If you don't have a properly sanded surface, paint may not adhere to certain items properly. You can oversand, undersand and often people underestimate its importance. But, you don't have to be a pro to sand a surface.

It is not recommended to use one product in place of another, as they serve different purposes. For example, while paint sealer can be used to seal a surface, it is not recommended to use it as a primer or undercoat.
Sanding sealer should be applied after the wood has been sanded down to a bare finish, but before the topcoat (such as paint).
While sanding sealer isn't always necessary, it can be particularly beneficial for: Porous woods: As we've mentioned, sanding sealer's main job is to effectively fill in wood pores. This makes sanding sealers a must-have for open-grained woods like oak, mahogany, and ash, where the pores are more visible.

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.

If movement should occur in a joint sealant with a caulking, which has been painted, the caulking will move, and the paint will crack.

Bonding primer: Specially formulated primers can create a strong bond between paint and varnish, even without sanding. However, these primers can be expensive and may not be as durable as a sanded and primed surface.
If you paint directly over old paint or finish without sanding, the new coat of paint may not adhere properly or react with the existing layers, leading to a poor finish.
