Gotcha…It’s definitely good at removing tannin stains. I just didn’t get what he was saying about citric and furring. I just don’t see how it would help with that.
Anything over 80 grit will begin to close the pores back up on the wood, which means less stain penetration. Interior wood the finer sandpaper is no big deal, exterior it is recommended to not go over 80. This is for decks. I couldn’t imagine sanding a fence. Maybe hit extremely furred areas with an Osborn brush if you think it is bad.
It doesn’t take much to knock the furring off. You can sometimes even remove it with a brush. I never even mess with the furring as part of a regular cleaning. If I’m staining I’ll include sanding as a separate line item. It’s up to them if they want to pay it. I don’t spend much time sanding either. It seems like it’s usually only the spindles that fur up bad. A quick hit with an orbital and I call it good. You can usually knock most of the fur off where the sander won’t get by hand with a couple quick swipes using 50 grit.
I agree with @SurfaceTherapy about not sanding fences. Heck, they almost come from the factory with furring or at least with that rough cut look. I’ve never used sandpaper on a fence and likely never will unless I accidentally cause some damage or something.
Just bought this dewalt 20v battery orbital sander and both 60 and 100 grit packs of 50. I have the 120v as I rarely use it for the sign business but quickly using cordless is what’s up. Thanks for the clarification everyone! DEWALT 20V MAX Orbital Sander, Tool Only (DCW210B) https://www.amazon.com/dp/B07JQM7C28/ref=cm_sw_r_cp_api_i_fDxtEb2EBPWV0
If you would let me know how what ah battery your using in that sander and how long it lasts. I have quite a few Dewalt battery operated tools but have never used the sander. I have a weed eater that lasts about 30 minutes using a 5 ah battery. I imagine a sander would last longer. I could see it coming in handy at times. Although, most decks usually have an outlet nearby. I still like the convenience of battery tools though and they sure have come a long ways.
