P240 is going to be handy for when you’re painting. After you’ve given to your project an undercoat and then you’re given out a topcoat give it a rub down with some P240 and that’s going to give you a super smooth finish. This sits below coarse sandpaper and includes 24 and 36 grit sandpaper. It is used for jobs that have a lot of paint or varnish to remove. It's often used on rough timber that needs to be smoothed out and the first sanding when sanding floorboards. What does the P mean in sandpaper grits? P120 Sandpaper– Any wood that was too soft for P80 will start the latter at P120. We generally use this grit when first smoothing pine, redwood, & cedar. Lastly, enamel paints and polyurethane don’t require the wood to be sanded beyond P120. The only exception would be a clear satin finish, in which case you may want to eliminate any scratches left on the wood with P150 or P180.

This is used to initiate wood polishing. FEPA standards classify these types of sandpaper grit as P400, P500, or P600 while CAMI classifies them as 360 or 320, and diameter sizes range between 25.8 to 36.0 micrometers. Super Fine P220 Sandpaper– For novice woodworkers, it’s time that we tell you that you have to sand with multiple grits. And P220 is generally the go-to 2nd & 3rd level abrasive for prepping wood for oil finishes. But in the case that you’re applying a wood stain, your destination does stop here. Finishing Sandpaper Grits

Micro Grits

So for a regular wood project, I would only finish it off with P120 sandpaper. Just ensuring that there are no sharp edges on there at all. However, if I was going to paint a surface after I finished it off with a 120 paper then painted it I would then rub it down with P240 sandpaper. Once this panel has had an undercoat and then you rub it down with a bit of P240 that’s going to give it a super smooth finish ready for a topcoat. Final Thoughts P120 that’s also going to help to do similar to what the P80 grit does, but it is going to give you a smoother finish. I probably wouldn’t recommend this for stripping paint. But if you’re going to be rubbing down between coats where you just want to smooth down some paint before painting it again P120 is good. Also good for your rough woodworking. P80 Sandpaper– This is the starting grit for most hardwoods and is a staple for every wood worker. P80 grit is the best option for removing saw blade burns and deeper surface scratches. In the case that you’re working with a hardwood like Poplar, you can probably jump the line to P120. Medium Sanding Grades P400 Sandpaper– Only oil finishes like tung oil & teak oil require the surface to be finished to this level. And it’s also not a requirement for all wood working projects that use those types of finishes. Lastly, you can rely on P400 to smooth the top coats of polyurethane. The micro grit types of sandpaper grit are classified as follows and are primarily used for small, precise sanding, like taking off coats of finish or smoothing small areas of buildup.
