    Hi! We bought our first house last year. It’s 1929 with mostly plaster walls. We have had folks suggest we just drywall because it’s easier than dealing with plaster despite nothing being wrong with it! Excited to learn how to care for our home! ❤️ thanks for this video!!

    We just bought a house in North Wilmington, DE (Belfonte) and the house is OLD!!! Built in 1915 and most of the house is wooden math and plaster walls. I showed my girl this video so she could understand why a lot of the walls are wavy and have imperfections. This was an amazing explanation!!! Thank You!!

    Thanks! This was the best explanation yet I've seen of how plaster. lath and studs are utilized to build these walls. I own a early 1890s brownstone and always fear mounting pictures and paintings. Now I know to look for the studs. You may have a few tricks for doing that. Any advice would be welcome. Thanks again.

    Great intro to lathe and plaster. Could you talk a bit about how these were insulated? I have wall with lathe and plaster beside a chimney, and it's crumbling. I was thinking I'd put 1" foam panels on the interior and then drywall, but don't want to trap moisture between the plaster and the outer wall.

    • @amandaboyce4140
      @amandaboyce4140 Год назад

      To my understanding, most lath and plaster does not have interior insulation. Lath and plaster walls are thicker and have a higher insulation and noise cancelling rating than drywall does.

    Hey I'm glad I ran into this video again, lath and plaster is a beast of it's own , typically with lath and plaster comes the pain of knob and tubing... that being said I'm scoping out my so's house and have seen plenty of no no's when it comes to the electrical very scary... and a lot of it has been damaged to the point where it should all be mitigated, do you know if it was typical for that time period to run straight shots from the basement to the attics as I would like to re use the same passages as much as possible I already have some repair to do on the plaster I would like to limit how much I have to do thank you!

    That makes A LOT of sense! I have to totally replace some lath in my 1907 house. There's a hole where there must've been some kind of register. I have to do a small section then plaster it. I was wondering how the plaster would stick to the lath and what the heck a key meant. Thanks!

      Wally didn’t answer, but 2 years later, I will in case anyone cares. The “key” is the bulge of plaster that comes between the strips of lathe to lock or “key” the plaster to the lathe.

Have a feeling my house might not have very "standard" and "even" stud spacing.

    Hi Rory @BigWalleze, I need to install an 8 pound fire extinguisher on the wall, and I can't find the studs. (1) Would 8 pounds be too heavy for lath? 4 screws - horizontally 1 inch between 2, vertically 5" between the pairs. (2) Is there a way to drill pilot holes and then screw through the lath without damaging the bond between the plaster and the lath? (3) any way to minimize the risk that 2 of the screws - or all 4 - will go into the gaps between the lath?

It had no kitchen cabinets, but I think the new ones I had installed were done the same as on drywall because they are pulling away from the walls. I'm too scared to put anything in them now. Do you have a video that shows how to hang regular heavy kitchen cabinets on a 1940s plaster Paris walls? Thanks

    This is a really helpful visual, thank you! Now I know why stuff falls behind the wall when I drive a nail in to hang something! My house has a lot of faux wood paneling, which I now wonder if it was used to cover up any blemishes in the plaster! I absolutely can't stand the paneling and the plastered walls are always cold to the touch (even in the summer)!! It's a lose-lose!

    • @MrWolfSnack
      @MrWolfSnack 3 года назад +6

      You have to find the stud when you want to hang something on the wall, you can't just hammer it in wherever. The wood paneling was not used to cover up anything, it was a popular renovation style in the late 60s through the early 1980s as that was the new thing. Just like wall to wall carpet did in the 1950's. Cold walls in the summer are not a problem at all, you want your house to be cool. Also plaster is a masonry material so it is not an insulator of heat, it always reflects heat off. Also in most early construction homes of lathe and plaster, its very common they have no insulation at all (it had not been invented yet) and if there is any, it's likely going to be old newspapers glued into the back of the exterior wall which was all people knew at the time on how to insulate their home from drafts.

    Problem: My plaster wall is flaking and blistering below my windows. I've repaired the area before by removing material into the base coat. Then I used structolite with surface coatings of joint compound. It looked great, but the problem came back. I assume that it is moisture related. Any ideas on where to find the source of the problem (what is the most common cause) so that a final repair can be made. Thanks.

    • @BigWalleze
      @BigWalleze  10 лет назад +4

      Hi johnott1864,
      It sounds like you are indeed having a problem with moisture. There are a lot of spots around a window where moisture can leak in. I would investigate around the frame and under the trim. Condensation from the window itself could be an issue, too, especially if you live in a climate where condensation can freeze overnight and melt in the morning. Keep looking, and remember that water runs downhill - the source could be higher up than where you first see damage.
      Structolite is a gypsum plaster, which makes it extremely susceptible to water damage. Think of rain on sidewalk chalk. This is one reason Big Wally's Patching Plaster is lime based - it works more effectively in these situations. When you make the final repair, remove all the blistering parts and spray the remaining plaster with Big Wally's Conditioner, which will partially seal and consolidate the brittle original plaster and prepare the surface for your new patch coat.
      Hope this helps. Good luck with your project!

    Brendan L thinks your wet plaster would feel good inside. Cut black trans out of lathe and restore their broken plaster holes.

    Tore down and wasted a 12×14 ceiling because a pizza sized section had fallen due to water damage. Dust left me sick as a dog for weeks. Wish applying plastercand lathe wasn't such a lost art and i could have found someone to repair it instead.

    I really hate this old plaster ,we are currently demoing some apartments it's alot of trash 🗑, insulation ,lath and plaster and some places it has double layer drywall but for sure one layer drywall and this mess ,I was really curious about how they did it back then ,real 2x4 ,4x4, 2x8 on ceilings and 2x10 on floors ,unlike today's 1.5"×3.5" cheap wood 🪵

    On my last comment I meant to say 'plaster' walls, not 'player'.

    If I get a old house I would just remove all the laths and plaster and then place dry wall over the studs
