Which sanding machine is best for drywall corner sanding?

[bzotya]

I already have the Planex for the main areas to sand now I'm wondering which sanding machine would be the best for the inside corners to sand?
Thanks for your response.

How clean are your inside corners?

Also, how close into the corners do you sand with the Planex? (pretty close Id assume, within 20mm?)

Some may suggest the LS130 with a 90o profile, followed by a very light hand sand to remove the traits of a linear sander. Other's are going to suggest RTS400, DTS400 as options. Any of these will achieve a result - it really depends how you want to work.

I wouldn't consider the RO90 with delta for this specific purpose.

Definitely the DTS400. Great with corners thanks to the shape, and great with drywall thanks to the good dust collection. Just remember to turn the suction down.

if you pull the protective cover off the front of the Planex you can get pretty close to inside corners.

Thank you for your opinions.
I was thinking DTS400 would be a good choice but in the same time I'm worried the pad stroke might going to ruin the opposite side of the corner. Maybe the LS130 would be a better choice since that running linear motion.

One trick is to have something like a long metal edge in your other hand (maybe fabricate something with a handle or use one of the long cutting in blades painters use) ... that way you can protect the edge you're not sanding if you choose to use something like the DTS.

I was in professional  painting for 25 year and I never owned a tool like that, but obviously a great idea.
Thank you for that.

I'm in the middle of doing just that. I'm using the DTS 400 and it works quite well.

I really enjoy the DTS400 in corners for drywall sanding. The beveled edge on the pad keeps the adjacent side of the corner from getting gouged. The DTS and ETS125 (for open road) are my go to sanders for small scale drywall patch sanding. 220 or 240 Granat works really well on skims. The dust extraction is very good with both.

The extractable HSK are great in the "muscles not motors" category for patch and skim sanding as well.

I own and have used one of those but because mine is 24" long, it becomes rather unwieldly at times. Now I use a 10" taping knife instead.

I use a cut down juice carton to protect the wall when sanding or doing any other kind of work against it.

There are plenty of sloppy professionals too!  [scared]

 

[tbellemare]

With the beveled edge of the pad on the DTS, it doesn't mar the adjacent surface.

I use the edge of my 10" taping knife when sanding adjacent edges.  It's usually right there any way.  Works for painting also.

 

[Brent Taylor]

I use a RO 90 with the extended delta pad and a 400. It gives me good results.

The juice over here is in 750-ml bottles???

Or a piece of paper on a block for hand sanding the corners?

  So true....A 'hands on' approach at times still works well.... ;D

Those extractable hand sanders are helpful in a bunch of situations. On drywall sanding, regardless of tool choice, the ability to capture the dust before it goes airborne is key.

Scott,

Any recommendations for painting shop walls (new drywall).  Thinking I'll use Valspar® Interior Drywall
Primer-Sealer followed by Valspar Ultra 2000 Interior Satin.

Thx.
