Hot take: a guy at the lumber yard in Tacoma said I sand wrong and it messed me up
I was building a bookshelf out of red oak last month and burning through sandpaper way too fast, like a full sheet every 10 minutes. This older guy at the yard watched me for a second and said "you're pressing too hard, let the paper do the work." I thought he was being a jerk but I tried it, light pressure, let the sander float, and the same sheet lasted 40 minutes. My finish came out way smoother too, no swirl marks like before. Now I'm wondering what other stuff I'm forcing that I should just let happen, has anyone else had someone call out their technique like that?
Did the guy explain why pressing harder actually makes it worse, like does it just clog the paper faster or is there something about heat and friction ruining the grit? I've always been a "push harder to get it done quicker" type and now I'm second guessing every time I've ever sanded anything. Maybe it's just me but I feel like nobody ever actually teaches this stuff, you just copy whatever your dad did in the garage.
