IT’S ALL ABOUT BE­ING ABRA­SIVE!

Better Homes and Gardens (Australia) - - Tool Talk -

You will of­ten see a grit num­ber quoted when re­fer­ring to sand­pa­per. This re­flects the size of the par­ti­cles on the abra­sive. The lower the num­ber, the coarser it is. You gen­er­ally start a job with a low num­ber, then move to higher grades to get a smooth fin­ish. You use 40 to 80 grit pa­per for re­mov­ing old fin­ishes and smoothing rough tim­ber. The most com­monly used is the 120-180 grit range, which cre­ates a smooth fin­ish on most ma­te­ri­als. Fine fin­ish­ing work should be done with 240 grit and above. This will re­move any mi­nor scratches left by lower-grade pa­pers.
