Wet sanding it for polishing not drywall finishing.....JS

 

And when would you "polish" a wall?

 

Polish the base coat. Sponge, mop, or wet trowel. No lines or buggers, and no sanding before top coat.

 

Just glaze the whole ceiling..no sanding and level5 at the same time. Just roll and wipe, keep a wet edge. If you do have to sand, it will just be a lap where you pulled wet into dry, and at that point you can sand with wet sponge..imo

 

Brightstar, you are talking about plaster??

 

I'm talking about drywall seams. Hot mud/base coat. Dampen it, wipe it flat, then top it.

Hot mud will polish up/shine when hard. A.k.a. like glass.

 

I've 'wet sanded' a few times on smaller jobs, patches etc so as not to come back for a small sand.
On a full job I would say top over as per usual, but anywhere that requires a pass over (like but join to recess join), I would coat one or the other, let's say butt join, let it go bone dry, then coat recess. Maybe butt joins, internals and externals one day then recesses the other. Then tight skim coat type patching where necessary. A sand would b just a wet sponge on all edges and leave centres.
I wouldn't do it on a full house but if I had to, I'd do that.

 

When Polishing your pressing the base coat flat and smooth on the edges, good enough to top coat. Its different than most would do. But works well.

 

Sanding is for woodworkers ... :whistling2:

 

It was looking ok, but I wasnt confident in the finish so I sanded it, only have to clean the mess once, rather than look at one for 30 years
