What happens here

When repainting or refinishing and applying multiple coats, it is very important to sand between each coat. The purpose of this intercoat sanding is not to level the surface or remove material, but rather to create a 'scratch' or a fine texture on the surface. This scratch provides an improved mechanical anchor for the subsequent layer of paint to lock into, which is crucial for preventing scratching off or peeling of the paint finish. For manual sanding, the expert recommends using a 180 or 220 grit sanding sponge to achieve a light scratch. If using a sander, a very fine grit sandpaper should be used to apply just a light scratch to the surface.

Goal: Ensure paint adhesion and durability between coats by properly sanding.

Tools and materials

  • Sander — Applying a very fine, light scratch to the paint surface. Use with very fine grit sandpaper
  • Sanding Sponge Unida — Creating a light scratch on the paint surface for improved adhesion of subsequent coats
  • Sandpaper — Used with a sander to create a very fine, light scratch on the paint surface

What they say

very important the reason we stand between coaches not to level and that's a big misunderstanding people think you know you're removing material but we're not removing material what we're doing is we're putting in a scratch for the next layer to lock into you need that scratch for it to lock into to prevent any type of scratching off of the paint or appealing of the paint so what would be a recommended grit that I would um sand in between coats I usually use a like a 180 or 220 grit sponge real light scratch if I'm using a sander I may go very fine and just a light scratch cool
