I just bought a 100 year old house and stripped off about 5 layers of wallpaper. The walls are plaster and lathe, and not in terrible condition so I am going to attempt to skim coat - there seem to be a ton of differing opinions about how to do this. I am leaning towards rolling on a slightly thinned all purpose joint compound and smoothing with a "magic trowel", as it seems like relatively simple method for a beginner like myself, but was wondering if anybody has experience with this method?

Also, is it necessary to prime the walls before skim coating? Or is there any sort of bonding product I should use, or can I just put the joint compound directly on the plaster?

Thanks!

The most important factor is making sure all the glue residue is removed. I have found that it usually requires 2 or 3 hot water wipes to totally remove.
If you have dips that need leveled out, I recommend using 45 or 90 min dura bond since it dries quicker.Then skim over with regular drywall compound and sand smooth when dry.
Priming is a good thing, but I have found that it is not always necessary.
You can thin a little and apply with trowel in a workable area. the compound will begin to set up so you have to work quick. If it begins to set up, you can spray a little water on with a spray bottle.
Hope this was helpful

I have an old house built in 1925 that has bumpy plaster walls(like bad patch jobs not textured). I don't have a huge income and would like to resurface the living room walls on my own. I have done some research and found that a lot of people use a skim coat of JC to do this. My walls have glossy paint over the plaster.
My questions are...
Should I degloss the paint so the JC adheres better?
Do I use Durabond instead of deglossing the paint?
Do I use JC or another product all together?
Use screen over JC than put more JC over the screen?

There are so many different ways I have read about that I'm not sure what method to use. The walls are in decent condition. Just seems to be a bunch of -nail- holes that were filled bad.
Does anyone have suggestions that won't cost alot, make a huge mess or clean up, and simple enough for someone who has only done a hand full of home DIY projects.

Will take all suggestions into consideration
Thank you in advance

I want to be the best steward possible for this stoic but graceful four-square so she can stand for another 120 years.

I would love to see a reply to BV011273's post as it describes my situation with one caveat. Of all the blogs, DIY tutorials and forum posts I've read about skimming with JC over plaster, none of them address the most basic of questions.

In an old breather home, *should* you skim with JC at all? How does the composition of Joint Compound itself affect overall breathability of the walls?

Also, What does the added moisture in the initial wet application do to the old wall under it while it dries.

When should you absolutely NOT use JC to skim an old wall?

TIA!
