120 is 120% of 100.
100*12/120 = 10%100*12/120 = 10%100*12/120 = 10%100*12/120 = 10%
120% of 100 = 120
100+120=220.
The percentage reduction = (120 - 90) x 100 / 120 = 30 x 100/120 = 25%
For sanding pallet wood, it is recommended to start with a medium grit sandpaper, such as 80 or 100 grit, to remove rough surfaces and imperfections. You can then progress to a finer grit, like 120 or 150, for a smoother finish.
The recommended sandpaper grit for deck refinishing is typically between 60 and 80 grit for initial sanding to remove old finish and smooth the surface, followed by 100 to 120 grit for a finer finish before staining or sealing.
For removing stain from wood, start with a medium grit sandpaper, such as 80 or 100 grit, to effectively strip away the old finish. You can then progress to a finer grit, like 120 or 150, for a smoother finish before refinishing the wood.
For effectively removing stain from a surface, start with a medium grit sandpaper, such as 80-120 grit, to strip away the top layers of the stain. Then, switch to a finer grit sandpaper, like 150-220 grit, to smooth out the surface and remove any remaining residue.
For refinishing wood floors, it is recommended to start with a coarse grit sandpaper, such as 36 or 40 grit, to remove old finish and level the surface. Gradually move to finer grits, such as 60, 80, and 100, for a smoother finish. Finish with a very fine grit, like 120 or 150, for a polished look.
The recommended grit of sandpaper for smoothing out rough surfaces is typically between 80 and 120 grit.
