Orbital Sanding disc grit recommendation?

[dclark2171]

I doing a small board and batton job in our bath. The walls are smooth, but seem to have a slight "eggshell" texture. What grit of orbital sanding disc to smooth the wainscotting areas to be more like smooth drywall?

My best guess would be something between 80 and 180. If I had 120 I would start there and see how it looks.

a lot will depend on the paint. latex will fill the paper a lot faster than oil base as it tends to be a bit "gummy"
I agree , try 80 and see what that does

Oh wait this is painted. Yeah 80....

And remember you're going to raise a lot of dust, so be prepared for that mask up. Use a sander with good dust collection. Preferably connected to a vac. Festool is really good about that but there are others

I would add to use a bag in the vacuum. Better for the surrounding area and easier clean up.

great advice. I have a cordless Bosch orbital sander and from what I gather, the dust collection is better than most (non Festool) when connected to a shop vac. Since I will be using this to sand down nail patches and seems on the trim itself, I may get a smaller shop vac because mine is really big. Also good idea with using a bag in the vac. The current paint is latex. I'll only be sanding from behind the Board and batten area.

If you are going to board over it, why bother to sand it?

I'm not boarding over it (I use the term B&B loosly).

So typically when I connect a vacuum to a sander I adjust the output of the vacuum so that it just ***** the sander down. If the vacuum is on full it will pull the sander very strongly against what I'm sanding and then you're more likely to leave swirls. So hopefully you have an adjustable vacuum cleared out. Always sanding on full power.

Well...

Did you use "eggshell" loosely too?

A pic of the texture and a better explanation of what you're trying to achieve will probably get better answers.

 

[cvairwerks]

Extremely loosely...

I’d look into Diablo Sanding Screens. I bought a huge pack to HD over the holidays. Supposed to clog less on paint.

And with an assortment pack on hand, you can switch easily.

I've had a lot of good luck with their sandpapers. 3M also has something similar. Biggest tissue. Was it depending on your sand or you may want a specific pad for it. Just cuz it can clog up the pads. But on most Sanders I own it's pretty easy to just get a new pad and replace it and they are not crazy expensive
