Dts400 or ro90 for stripping window & frames?

[Acrobat]

Hi, I have a question regarding what tool would you recommend as best suited for sanding back paint from a heap of window frames and door frames and weatherboards. And what papers should I use? I have an old weatherboard house and the sun and weather killed the paintwork and it's cracked badly and some boards are in poor nick, I need to sand back to bare board in quite a few areas and reprime and repaint anew.

Is brilliant 2 the one to use for this task? 60  or 80 grit?  Is the delta400 up for it or am i better off to try a ro90?. I have a rotex 125 but feel its too big and a bit awkward for vertical work like this and possibly unweildy to use for long periods of time and of course being a round disc cannot get into corners, and am thinking maybe the dts400 won't have enough oomph to cut through many layers of paint quickly enough and wondering if the ro90 is more suited here.
Thanks

I'd be looking at the RO90.  With the more aggressive mode using the round pads it should make the work faster.  Festool envisioned the RO90 for just this use and you can by the accessory guards to protect against rubbing the glass.

Like Peter suggested, I think you would be best served by the RO 90. It's going to strip at a faster pace than the DTS. I would recommend Granat abrasives and I think the 60-80 grit range would do well.

You might want to read this PDF review of the RAS 115 for your specific purpose. It was posted on Festoolusa's site. Might change your mind about the tool to use for the windows.

RO 90, the raz is too aggressive you will burn right through the profiles.
I agree 60,80, 100 grit will work well.
I like to use Cristal if the paint is thick and layered, the thicker paper stands up well to multiple coats of flaking old paint. Otherwise granat is great too.

One more vote for the RO90, best suited for this job if you want fast removal. I'd try to do the bulk of the work with the 125 though. And only use the 90 for the spots where the 125 can't reach comfortably . Granat or Brilliant in 60 or 80 grit will do fine for removal, and smooth it all out with 120 grit. Agree with Tim that for even faster removal of paint you'll want Cristal. 

The RAS is better suited for the weatherboards and large areas, a bit less on door and window frames.

Ok, the ro90 looks like the consensus here, thanks for everyones advice. Big job ahead!

I too vote for the RO-90 abut I also use my LS-130 almost as much.

. Small note, Cristal has been discontinued and I believe it was never offered for the RO 90.  So, Granat it is.

Thanks. I have only used Granat with my RO 90. I am not crazy about the thinner (Cristal) paper....

I'm about to start the same project with my Rotex 90.  In my case, however, the oak frames are finished with a clear coat (varnish i suppose?  it's decades old), which is flaking, rubbed off, or weathered through in many spots.  Is Granat still the sandpaper I should use, or should I instead go for the Rubin 2, since there's not much to sand through until I get to the raw wood.

Stay with Granat. It works very well on bare wood and is far more versatile than Rubin.

I have a little Rubin II and a lot of Granat for my RO90, and have found the Granat to work as well, if not better in all occasions I've used it - sanding finishes and bare wood.

From my limited experience, I'd recommend you go with Granat if you are just starting to put together an abrasives assortment.

  Don't use Rubin on a Finish, it will get clogged. Granat or Brilliant 2 resist clogging or corning of the finish that you're trying to remove.
Save the Rubin for bare wood, or as others have posted, you can use the Granat all the way through the job.

Thanks for the tip.  Someone should tell the Festool dealer who instead recommended the Rubin for the project that Granat is the better way to go for this application!

+1.

The Rubin paper pre-dates the Granat by quite a few years. The Granat is newer technology and seems (to me at least) to be superior in nearly every way. Being relatively new to the green addiction, I went with all Granat for all of my sanders.

Rubin II is actually newer than Granat.

Granat is different, not superior. Better suited than Rubin for some tasks. But for bare wood I find Rubin better than Granat, it cuts faster and better and leaves a nicer colour to the wood so you can get a nicer end result after finishing. Rubin is the bare wood specialist, and less suited for other materials, though if you're in a pinch it can work. Granat on the other hand is a great all rounder that does well almost anywhere.
