Choosing the Right Sandpaper Grit For heavy sanding and stripping, you need coarse sandpaper grit measuring 40- to 60-grit; for smoothing surfaces and removing small imperfections, choose medium sandpaper from 80- to 120-grit sandpaper. To finish surfaces smoothly, use a super fine sandpaper with 400- to 600-grit.
240 Grit With its very fine texture, 240 grit sandpaper is ideal for sanding finishes between coats. It's gentle enough to smooth down dried layers without damaging them, giving a polished look while maintaining the integrity of each layer. It's also effective for finishing touches on bare wood.
The coarsest grade, designated as extra-coarse, includes 24-, 30- and 36-grit paper. The finest grade (i.e. ultra-fine) includes 800- and 1,000-grit paper.
Medium grit sandpaper can create a smooth finish without leaving any scratches. Fine sandpaper is used for creating a smooth, polished finish. It is often used to sand wood before applying a finish, or to polish metal. Fine grit sandpaper can also be used to remove minor scratches from a surface.
Yet for all of his projects he uses just three different types of sandpaper: 120 grit as a medium do-everything sandpaper, 80 grit when he really wants to do some shaping or needs to remove a lot of material, and 220 grit for fine sanding between coats of polyurethane so each coat can bond to the next.

Gold aluminum oxide stearate abrasives are a very popular product for woodworking and sanding wood. The stearate coating over the aluminum oxide grains prevents loading, which speeds up the sanding process as you won't constantly be changing clogged sandpaper.
Always start with the coarsest grit you're planning to use. It will help you remove the bulk of the roughness, and you can touch up any mistakes with finer grits afterward. After the first coarse sanding, gradually work through finer and finer grits for a flawless finish.

A “P” in front of the grit size indicates that the product is graded in accordance with the European FEPA standard. You should always look for products with a P in front of the grit size as being measured by this standard ensures for an accurate number and a smooth sanding.
The grit of sandpapers is a rating of the size of abrasive materials on the sandpaper. The higher grit number is equivalent to a finer abrasive, which creates smoother surface finishes. Lower grit numbers represent coarser abrasives that scrape off materials much quicker.
180 to 220 Grit Sandpaper: Finer grit sandpaper is great for removing the scratches left by coarser grits on unfinished wood and for lightly sanding between coats of paint. 320 to 400 Grit Sandpaper: Very fine grit sandpaper is used for light sanding between coats of finish and to sand metal and other hard surfaces.
Ultra-fine sandpaper is the finest. When the grit is between 800 and 1,000, it falls into this category. It's used for polishing surfaces that need a smooth finish or may be susceptible to damage with anything coarser.
Very Fine Grit Sandpaper (400-800 Grit): If you require an exceptionally smooth surface on your XPS foam project, very fine grit sandpaper is the answer. This grade is excellent for final touches, polishing, and preparing the foam for intricate detailing or painting.
Common sizes are, from coarse to fine: 40, 46, 54, 60, 70, 80, 90, 100, 120, 180, 220, 320, F, and FF. A 46 or 54 grade cloth is used on roughly filed work, while 220 to 320 grit cloth will give a good polish. By the successive use of progressively finer mesh emery paper, near-mirror finishes can be obtained.
If you want your paint to have a smooth finish, the technique you use is very important. Keep your brush at a 90-degree angle while applying the paint and feather as you go. Between coats, sand the wall lightly using a very high grit sand sponge of at least 220 grit.
Before the new coat of paint is applied, 400-grit paper makes prepping smooth and easy. If there are any rough areas spotted along the surface or edges of a given panel, 400-grit could be used to smooth the metal out in a way that lower grits might be incapable of.
Medium (80-120 grit): Perfect for smoothing surfaces and removing small imperfections. Fine (150-180 grit): Used for the final sanding before painting. Very Fine (220-240 grit): Ideal for sanding between coats of paint or primer. Extra Fine (280-320 grit): Best for achieving a smooth finish on the final coat.
Chalk paint is very popular for painting furniture and adheres to almost any surface without sanding. Another option would be a “furniture paint” (which I used on this cedar chest) sold at many home improvement stores. These “furniture paints” are good quality, thick paint that hardens into a durable coating.
What exactly is the Golden rule of sanding? The golden rule of sanding is to follow a progressive grit sequence. This means starting with coarser grit sandpaper and gradually transitioning to finer grits.
Selecting the Right Grit Sandpaper
For heavy sanding and stripping, you need coarse sandpaper measuring 40 to 60 grit; for smoothing surfaces and removing small imperfections, choose 80 to 120 grit sandpaper. For finishing surfaces smoothly, use extra fine sandpaper with 360 to 400 grit.
What grit sandpaper should I use for wood? A. For heavy sanding or stripping, go with coarse 60-grit sandpaper. If you just want to smooth the surface and remove minor imperfections, medium 120-grit sandpaper or higher is your best choice.
