Alternatives to Saphir paper for the RO90 and LS130?

[alltracman78]

I've been sanding my house prior to repainting. The old paint is latex, and the Saphir paper seems to work better than the Granant (doesn't clog as much).
However Festool only makes Saphir in 5, 6, and 9 inch rounds. Nothing for the RO90 or the LS130.
Is there a better alternative than the Granant paper specifically for paint? I've tried Serious Grit (seems to clog more than Granant) and the mesh paper doesn't seem to be available in the lower grits or do as well with latex paint.

Any other suggestions? Specifically for sanding latex paint. Klingspore? Cubitron? Anything else?

*Saphir, spell check got the better of me*

Not answering the question directly but possibly useful…:
I was recently stripping some finish and had a similar problem with clogging a Granat disc.  Having recently tidied my shop I remembered I had a stick of almost-unused abrasive cleaner purchased years ago — and it was miraculous, removing all the clog.  Later I tried it on a different disc clogged with something else and it was nowhere near as good, so YMMV.
Don’t remember where I got mine, but it’s like this one:https://www.woodcraft.com/products/woodriver-abrasive-belt-cleaner-1-1-2-x-1-1-2-x-8
It takes a few mins to really scrub a disc so perhaps not worth a pro’s time, but I’m just a tinkerer.

I use Klingspor quite a bit. 40, 60, 80 for stripping or blending, depending on the material involved.
It works well for me, but I have to admit that I started getting it because it is easy. We have a local rep, who comes in every few weeks. All I have to do is tell him what I want, it shows up like magic.
I have stayed with it because it works.
I get the discs for my RAS115 from him too.

Having to constantly clean defeats the purpose for me.

The Klingspor works well on paint?

I may just suck it up and use the granat. Most of it is with a 5 inch disc, so I can use the Saphir for that. Only the RO 90 and a bit of the LS130 don't have it. Which is a relatively small part of the job.

Other than the Pad size being so small on a RO90 to begin with, clogging on that size of a disc will frustrate you easily.
It almost seems like you've got Oil Based paint hiding under the Latex, but regardless, 40 or 60 grit Granat , along with the Crepe Rubber Cleaner Sticks is all I can suggest as well as the above Posters.
I think Crystal, however it was spelled, clogged a bit less than Granat in some applications but it's gone, so no going to it as a 2nd choice Abrasive.  [sad] [sad]

Another fan of the Powertec cleaning stick. I cut the large one in half and keep a half stick in the Systainer with the RO 90 & the RO 125. It should also work well on the LS 130.

I have one of those, and tried it. It doesn't seem to clean the paint off well, from the Granat anyways.
I've been trying to move the sander quickly to minimize heat. Seems to help.

I noticed the post comparing the Rubin to the Granat, and how Festool designed the particles to "break".
I grabbed a box of Rubin for the LS130. Curious if it will "cut" the paint better because of the sharpness.
Not too worried about heat buildup with the LS, so maybe less clogging than with the circular discs.

Most likely, the house is old.

Be aware that Rubin is not made to handle finishes. It’s for bare wood, doesn’t have sterates or coatings to prevent finish clogging like Granat or other Finish Removal Abrasives.
