Title: Planex not being effective with texture
Post by: bclark on June 18, 2018, 07:16 PM
We are in the midst of remodeling some of our house and I thought it would be a good time to fix some of the terrible texture on the walls and ceilings and go with a more smooth, flat surface.

I have a rotex 90 and put some 80 grit granat on it to see how well it would chew through the 2 or 3 layers of latex into the knockdown on the walls.  It worked reasonably well with the first pass taking off all the paint on the high areas and flattening everything decently with a few subsequent passes (I do plan to skim coat so I'm not trying get it perfect).  I felt like the planex would be a good investment with the amount of area that I wanted to do this to.

I ordered a planex and some 80 grit granat and when I first tried it out it wasn't making much of an impact so I decided to get some 36 grit saphir.  That came in the other day and I'm still extremely underwhelmed by the performance.  It's so ineffective that I can sand an area at least 5x as fast with the rotex and even a hand sander with 60 grit seems to be faster.

There doesn't appear to be anything wrong with the planex itself.  I'm just applying light pressure and have it turned up to max speed.  Is there something I'm completely missing with this?  Should I just talk to festool?  I'm a little bummed because I would expect it to keep up with the rotex at the very least.

While I have zero experience with the the Planex, the Rotex regardless of size, is an animal. Short of the RAS or a belt sander, do not expect anything the keep up with the material removal of a Rotex.

While it may seem counter intuitive, try turning your speed down on the Planex.

Try using 24 granite, works very well with painted Texture. Then hit it with 220 grit and skim where needed.
