120 foam back starting on the ceilings so it is more like a 150 when i get to the walls then a fine sponge and lightbulb on the walls

The first 10 years I used the PC we used 100 grit exclusively. Never seemed to have any problems with it and we did a ton of houses. For whatever reason I graduated to 120 grit and that's what I used until I quit using sandpaper. The last couple years we used the sanding pads we really struggled with them for some reason. It was polishing the compound more than sanding. The first job or two we wrote it off as "it must have been the conditions" but after two years and all sorts of conditions that wasn't the case. Still never figured out what the problem was, but the Capt. helped me out introducing us to the sanding screens for the PC. These made sanding fun again! lol We are using the 180 grit screens, but may bump up to 220.

I was told by a mud rep that the mud had to much vinyl in, and they would change the ratio from winter to summer. The vinyl (PVA) keeps the mud from dehydrating to fast in hot temps. That made sense because i always had problems with glossy mud in the summer....go figure

i prefer joest or richard perforated sandpaper for finish sanding and Wet-Kut for pole sanding

I'm biased... But Festool sandpaper on a Festool sander is what I use.. Otherwise I'm using wet sanding paper for some fine finish.

Today instead of driving 30 miles out of my way to Lowe's to buy my quick change hook and loop for my gator sanders . I had a pack of 3m sandblaster 220 [red] ,,and a can of 3m super 77 spray adhesive in the truck. Took an worn out piece of hook and loop ,and spray glued a piece of 3m sandblaster to It , slapped It on my gator sander , and went to sanding. It worked great.
It only took a shot or two of glue. ,, saved a few dollars on sandpaper ,and
GAS.

Ive always used the porter cable discs 180 for the PC but yesterday tried the norton yellow ones with the hook&loop back. It sucked literally. Wouldnt come off the wall unless I turned it off while moving it or slid it off a bead. The suction was such that it popped the whole thing right off the machine like 10 times in an hour. The sanding however came out great no swirl marks or gouges like the PC pads. I saw some ones with little holes in them at all wall I might try those. Also I pole my corners with screen-kut 220 then block them

Right here we go, I find this amazing. Some well respected and highly experenced members of this colourful forum use 100g for sanding mud and sealer/undercoats??? So it weres down somewhat and you use it and it seems to work for you, I personally have seen otherwise but its got me curious as to what other members are using?? Im in the 220g camp for usg total and easyfinish and sealer/undercoats and between coats if you take it that far?? I dont know your other muds are like, obviously some are harder than others so need a courser paper, I use to use 150g for some nz made mud and thought that was rough enough on the boardpaper. To me 100g even if worn down will scratch mud, tear up sealers and make a mess, been there tryed and done that, not going back. So whats your fav sandpaper grit for the muds you are using then

80 grit screen for sanding off ridges between coats. 180 for final sanding

80 grit screen for sanding off ridges between coats. 180 for finish sanding. I never had issue sanding between coats as the 80 grit doesn’t produce a fine dust that will stop adhesion.
