    I bought a house thatโ€™s 100 years old.
    Will this be a temporary fix doing this to fix the plaster walls?
    Or with the winter months with the cold air from outside
    which is below zero will this be an ongoing repair issue?

  2. Joe Frugoli says:

    Tear it off and replaster it . Call a real plasterer. I have to eat too.
    Contrary to popular belief it not a dead trade.

  3. tkjazzer says:

    Can someone link a really good video on ripping out plaster, making traditional lime plaster, installing wooden lathes, and how to plaster?

  4. Tommy, Tommy, Tommy, why spend so much time trying to preserve failed plaster. For a sound repair: remove all unsound plaster, repair lath and/or supplement with expanded metal lath, then bond edges and re-plaster with gypsum plaster in a 3-coat application: scratch, brown, and finish coats. Using gypsum as an accelerant the whole patch can be done to a perfect finish in one day.

  5. Lisa says:

    Interesting. But I wonder about plasterboard with plaster over it? I have a nasty crack

  6. I Would of Just Ripped that wall down and installed a new plaster wall..

  7. Albert Rent says:

  8. Darren Deane says:

    I dont get it? Why not break it out to the wood laths and replaster over. Even this old house people have become pot head idiots

  9. Joe A says:

    what is the adhesive, Tom?

  10. nyc nyc says:

    This is ridiculous.Just clean out all the mess up plaster.Then use strucolight to fill up the holes.Their is more to the story.Google the rest.Try to Google plastering YouTube in the UK.US guys are clueless.
    I live in old house in Brooklyn and do it the old fashioned way.Also joint compound will come off in time.

  11. The 'Big Wally" method or "How to turn a 2-hour job into a 2-day job"ย 

    Good method for a homeowner, but for the professional plasterer, waiting 24 hours for the adhesive to dry kills productivity. Again, waiting overnight till joint compound dries! Thats two days & two trips for the pro. Also, not fond of joint compound as a repair material. 6" knife"? Much better to use a 10" knife.

  12. Kai Waters says:

    so an entire section of plaster in my house has fallen off should i just remove it all and replace it with drywall the wood has started to rot also

  13. Thanks Tom and TOH…great video!

    Question: is it ok to use drywall compound on old plaster/lath walls? I have a 200 year old home and want to ensure I do the job right. Thanks very much!

  17. This old house should bring in Kirk Geordano from the Bay Area for plaster and exterior stucco the guys a magician and already had made thousands of plaster/stucco videos

  18. SERIOUSLY; you guys are nuts, this does not work / I have tried this and the only thing I have is a freaking mess which I must now fix with mud, lots of mud in with hopes of fixing this mess / do not believe these guys…

  20. ohh wow. We just bought a home that has lath/plaster walls with several cracks in the walls. This is helpful. ty

  21. Oscar Muffin says:

    Would have been easier to tear it off and re-plaster.

  22. Mustakrakish says:

  28. bluesky says:

    hours and thousands of dollars later… Anyone taking notes on this?

  29. bill1957111 says:

    Why didn't he tape the cracks?

  30. Kajan Nathan says:

    Why not skimcoat it

  31. Josh Snyder says:

    What kind of joint compound would you use- just regular drywall mud? I've been told that stuff wont bond well without conditioning the whole plaster surface first. Also, would you need to tape the cracks prior to finishing? Anybody have professional experience with these techniques? FYI, I wouldn't use Liquid Nails construction adhesive as a replacement glue; it dries exceptionally hard and you really want a flexible adhesive that will allow the system to move seasonally. So a good substitute would be one that dries flexible, adheres to plaster, and is thin enough to squeeze through cracks and holes. Again, any pro recommendations?
