I've had some with 25+ coats of paint, they just laugh at 80 grit.  heck, they laugh at 36 grit saphir too!!

It was an old door with at least 4 coats, probably full of lead and glossy latex being the last.  My experience has shown me the RAS removed the paint much faster than the Rotex.  I was a little skeptical when told that during a Gary Katz roadshow and the Festool rep sent me a demo and low and behold it was true.  I am not sure if it is because there are no holes in the RAS paper or what.  I was not thrilled about buying another sander but the RAS will save me time and money on exterior trim work, no more burning and greatly reduced scraping.  I would have liked to get the TS55 or the newer drills and not another sander.  It is also easier to handle than my 6 in. Rotex.  I still am getting the swivel dust collection figured out. It also helps to turn the rpms or whatever down as not to heat up the paint and clog the paper. Also the dust/debris collector attachment is not round on the sander, it isn't a big deal but it seems odd.

Festool does this on a few tools, it's to make the vac connection port more compact to help keep it out of the way.

Good Morning,
I have used Rotext sanders and the RAS on the same surfaces.  The RAS takes the paint off way faster than the Rotex.  Sometimes, it's so fast you have to watch it carefully.

I agree with those who say to use lower speeds when removing paint.  The sanding disks can get gummed up pretty fast at high speeds.

Thanks,
Matthew

Especially latex paint, or shellac, both of which will soften/melt into a gummy substance when heated up by the friction of sanding.  A clogged disk simply generates friction as its abrasive particles are not open to cut into the old finish.  I've removed a lot of old multi-layered paint and cracked plaster with my RO 125, and from that work have determined that lower speeds and coarser grits work best, e.g. 36 or 25 grit.  The RAS 125 is tempting me, too.

RAS + ETS = best combination?

Thank you for posting the comparison of the Rotex and the RAS. The RAS does not get nearly the same amount of attention and I was wondering how a paint removal head-to-head with the Rotex would turn out. I was wondering what you thought of the combination of the RAS and the ETS 125 (or ETS 150/3).  Setting aside the corner and detail sanders, the combination of the the RAS and the ETS would seem to enable any surface treatment without the weight and balance issues that can make the Rotex a handful, especially it seems, on vertical, overhead or small surfaces.

Hi, I have both the Rotex 150 and the RAS 115.  The Rotex is great for sanding and prepping bare wood or previously stripped wood.  And the switch between course and fine is great when sanding a project where all of a sudden you notice a gouge or something that needs a little extra something as you are moving on.  The RAS is perfect if your wanting to remove paint from a surface.  I tried to remove paint from the edge of some doors I am refinishing and the Rotex with 80 grit Brilliant on the course mode and got nowhere.  When I used the RAS and 80 grit Rubin, since I haven't ordered any Saphir and such, it took the paint off fast and still left the
Rubin fairly clean.  Go figure.

Garnet,

A couple of years ago I was wondering the same thing.  Here is a little experiment I tried to compare the RAS 115 versus the Rotex 150.  (note that the first photo is after 5 minutes with the rotex.  The rest were about the progress with the RAS.  Comparison Experiment RAS vs Rotex

There is no comparison between a Rotex and the RAS where paint removal is concerned!

The RAS works much more effectively at this.  However, the RAS is not as easy to control as the Rotex, and it throws around much more debris.  With practice, you'll get to the point where you can use the RAS to collect more debris by learning how to position the brushes and vacuum area.

Now, considering vertical and overhead work: both the RAS and the Rotex will be tiring to hold for any length of time.  Still, the RAS would be more effective.  Just make sure you have a good plan for all that debris that's going to come showering down onto your face!

Bottom line: if pure material removal is your goal, the RAS cannot be beaten -- not even close!

By the way, I also reviewed the Rotex sanders, where I get into some related details.  Check out these links:

Glad to see my reviews are still helpful.

Matthew,

Thank you so much for your reply. Beyond paint removal, I was hoping that the RAS could handle rough surface preparation down to a level where one of the ETS models (maybe the 150/3) could take over and complete the fine sanding. What do you think?

Based on the chart I posted, it seems that the two sanders (RAS+ETS) cover the full spectrum of sanding stages without a gap. Now, I realize that the Rotex might be faster (but less agile and heavier) than the ETS at some of the middle sanding stages and cleaner (but slower) than the RAS at some of the initial sanding stages, but the RAS+ETS combo has other advantages that would lead me to go that route as long as I can take a piece of wood from encrusted with old paint to a find finish.

With a bit of practice I think you could.
I use my ras up to 80 grit Rubin for exterior
preperation. It is fairly easy to put some dips and humps
in material with the ras.  You have 30 days to practice
and see if it works for you.

I would say, for sure, that the combination of the RAS and the ETS would do what you need.  Each one accomplishes something the other one does not do as well.  The RAS removes matrial more efficiently; the ETS handles more smoothly for finishing.

If you need more information, let me know!

I think a colleague used a Kutzall disc for a chair project with the RAS. Seemed to work great though dust was EVERYWHERE. But that would happen with any open ended grinder. Don't know which "grit" or how coarse his was, if there are several to choose from. I am pretty sure it was a Kutzall as he wanted me to order one too and share the freight.

I am really happy with the RAS115 and have barely used my Rotex 150 since getting one. I even bought one of the last RAS 115 in stock over here some time ago and kept it as a spare. Did sell it NIB a few weeks back and feel a pinch of regret. The RAS is one of the few machines I consider almost irreplacable for me and should it get stolen or lost in action I would surely miss it!
