I am assuming that you have started a DIY project only to discover whether sandpaper is to use as the initial coat or which one to use in between layers of paint? Are you familiar with the meanings behind the various sandpaper numbers? If not, keep reading to know what is 300 grit sandpaper.

What are the uses of 300 grit sandpaper?

Sandpaper with a grit range of 320 to 400 is used to lightly sand hard surfaces like metal and other hard surfaces as well as to prepare surfaces for finishing coatings. I hope this tells you what is 300 grit sandpaper used for.

What Is the grit of sandpaper?

Lower gauge numbers denote larger, coarser grits, and the opposite. Sandpaper grit is sized by a gauge number. In contrast to #1,000-grit paper, which is incredibly fine with small abrasive particles, #24 or #40 grit sandpaper is highly tough and harsh.

What are the types of sandpapers? 

1) Sandpaper between 40 and 80 grits

When using a belt sander to sand the edge of a stuck door, coarse grit sandpaper is a suitable option for harsh sanding and rapidly removing material.

2) Sandpaper between 100 and 150 grit

The majority of projects, from sanding unfinished wood to removing old varnish, can be started using medium-grit sandpaper.

3) Sandpaper of 180 to 220 grit:

For gently sanding between coats of paint and for eliminating scratches made by coarser grits on raw wood, finer grain sandpaper is fantastic.

How does grit in sandpaper work?

Sandpaper with a coarser, or lower-number grit, eliminates wood and other materials more quickly and efficiently than sandpaper with a finer grit. It performs this by cutting the surface-level fibres of the material. When you wish to remove a lot of material, produce a rounded edge, remove old paint, or eliminate imperfections, strong scratching is required. However, the rough sandpaper also produces deep cuts.

This is all about the 300 grit sandpaper and its uses.
