Clearly, this is not acceptable for us, so any help would be appreciated, as we would very much like to get it going and give it another shot tomorrow.

We had our quality control guy come in and have a look at these scratches and he informed us they were not going to pass inspection, nor would primer or paint seal them, and was confident they would show through the paint on finished walls. Does the mud used make a difference? is the planex best used on all-purpose mud or does this even play a factor in the way it sands? I imagine the mud type shouldn't matter, though I understand Machine Mudd is far softer then an all purpose mud. USG Corporation is making that job easier with its Sheetrock brand tuff-hide primer-surfacer that simultaneously skim-coats and primes new drywall in a single spray application to create a Level 5 finish in minutes. All skim coat has been done with CGC Machine Mudd. A Level 5 finishthe highest quality finish for drywall walls and ceilingscan be tedious and time-consuming. This time around sadly we had to use only a 10 inch box for a base fill coat, then we did final skim coat by hand. Our sprayers can fit a wide range of tip sizes for easy application of mud, primers, and paint. We normally run 10 and 12 inch coating boxes for coating our tapes. For Q3 and Q4 drywall finish and skim coats, Graco texture sprayers deliver high performance and consistent, high-quality finishes. Nothing we seem to do works, and before we give up entirely on this machine I'd like to hear from someone who has it and uses it regularly, to see what we could be doing wrong that leaves us with these circular pattern scratches?. We have tried various settings on the machine, lowered speeds and suctions, tried them both at medium levels (3 for speed and 3 as well for suction). If you do it right it wont even need sanding (or maybe just a wipe).

At any rate, just skim it again, and press firmly using the edge of the blade. A firmer application or a more thorough mix mightve helped prevent bubbles. They go in a circular pattern just the same as the head on the sander. Could be that your mud wasnt mixed well and had settled a bit, leaving excess water on top. It also includes a skim coat, which is a thin layer of joint compound that. No matter what we use we constantly have scratches all through our work. Level 3 is a recommended drywall finish for walls that will receive medium or. We attempted using 240 grit and also 320. So we are trying to sand and turn over to painters. So, firstly, our drywall taping job is at finish sand stage. Recently, we have been allowed to borrow a planex drywall sander from a local rep to test and see how it works before continuing with a purchase, as this is not a cheap machine we do not want to sink money into something that doesn't do that job.
