What types of walls are there in old homes?
How do you remove lath & plaster walls?
In this video, remodeling expert Brad Bachand explains everything you need to know about the wall finishes of old houses. If you have an older home that has plaster walls, there will be multiple things to watch out for.
Matching the width of the plaster is extremely challenging when patching. Because the width is not exactly the same in every area, it can take a larger amount of drywall finishing to match.
Textures over previous layers of texture can make matching nearly impossible.
Removing lath & plaster walls involves significantly more labor than removing drywall board wall covering.

I feel like you're talking about my house exactly, and it's a nightmare. Great video.
Thank you!!!
Yeah it’s not fun to renovate in houses like that. But at least you know and it doesn’t come as a surprise!
*With a wood lath application, plaster is adhered by a “mechanical bond”. Meaning the plaster keys between spaced pieces of wood, with no expectation of the plaster sticking to the wood itself.
*With a wire lath application, plaster is also adhered by “mechanical bond”. Obviously rather than the plaster keying between wood slats, it keys in between openings in a sheet of metal.
*With a rock lath (gypsum) application, plaster adheres by a “chemical bond”. This would be where the plaster doesn’t key into anything, but rather stays adhered strictly by melding with a solid piece of gypsum board.
Love it, thanks Sean!
I appreciate the comment
The chemical bond part always makes me wonder. I think when applying over solid base like rock lath or brick, plaster will still form a mechanical bond, just on a much smaller scale vs keying into the lath. I assume, capillary action drives water along with plaster material into the microscopic pores of the substrate, where it sets , keeping the plaster layer firmly attached to the base. So it ls the same thing as plaster over lath, just on microscopic level.
"talk to your painter" as though we aren't all watching this because we are broke and doing our own home repair.
Fair
Might not be as common as you imagine
😂😂😂
Well I'm broke enough that I've installed my own insulation, windows, and drywall, so certainly not hiring a painter lol.
Just have your servants do it.
This guy looks like a general contractor not a builder. A general contractor hires the actual craftsmen to do the actual work.
Thank you for this video. My walls are 1.25'' thick and was aware about the plaster and lath method except for this most recent development, which I encountered the wire and plaster application with some kind of cardboard (not cardboard box style like Amazon, some inferior version of particleboard) instead of drywall behind it.
Oh wow, yes that is uncommon but I have run into that. Only maybe 1 or 2 times but it exists for sure.
Thanks for watching
Thanks for the breakdown
My pleasure, thanks for watching!
In Brazil we still using lath and plaster.. a lot..
Makes sense. It’s a sturdy material
Drywall sucks. It’s really a shitty product. Plaster is serious , durable and doesn’t mold.
You’re not wrong there
Most "modern" materials are garbage compared to the old ways. The new houses will not last 100 years, they will be full of mold and rot within 20-50 years.
I just inherited a home w/the 1st type of plaster. Behind the walls it looks like wood slats w/concrete behind & most are pretty thick. I have holes, lots of cracks & was thinking it better to get rid of them and replace with drywall. Should I replace w/drywall or find someone who can replaster the wood? Is that a thing? If I put up drywall do I also take out the horizontal wood slats or put the drywall on them? My fear with the lath is the wiring behind it. I don't feel comfortable redoing the wall w/o having electrical checked. So should I just let the electrician access behind the lath on what he needs then after put drywall on top of it? My dad would know all of this, unfortunately he left me the house w/o all his knowledge. I'd rather have the knowledge.
An easy solution is to cut holes in the plaster to access and repair/replace the electrical. Then once that’s all done you can hang new drywall right over the existing plaster/lathe! You just have to use longer screws to be sure it penetrates all the way into the wood lathe
Thanks for the really informative video! Could you link to the video about restoring the old windows? Currently renovating a house built in 1945 and we would like to preserve the original windows if we can.
Hi! I’m not sure that video got published, I’m looking for it
@@HomeLoveConstruction okay thanks!!
I wanted to say “plaster is never sprayed on with a hose” but it may be today. I have old houses and it was never originally sprayed in with a hose but may be today if plaster is still used. Just like with paint, I would imagine that most work is getting the paint (or plaster) from the can to the wall!
True enough! Originally plaster was definitely hand applied
I am thinking of doing lath and plaster on my old barn. Sooooo step one would be either tar paper , slats and plaster or 2. wire plaster and slates. I think I will do the wire the barn is old hence the wood shrink so that I have a 1-2" opening on the boards. Now the Plaster the TYPE and when damp will not absorb the wet once dry?
I would do paper backed lathe so you get a continuous water barrier and the stucco doesn’t go through the spaces between the planks
@@HomeLoveConstruction When you say paper backed using what material . From what I was reading on the tar papers and such doesn't wear for long?
the building in canada i lived in and helped renovate it was made in 1888 and there was horse hair mixed in with the plaster
Omfg that’s amazing 😂
👏👏👏
👍🏼👍🏼
Asbestos and how to spot it?
Testing is the only reliable way. It can be in many materials but it’s easy to get an environmental company to test for it
Literally?
Literally
lit with literalls
Lol
