Testing The Burn Ability Of Walls

The lath board used in this video was very smooth and unlikely meant for walls but this would not affect the test it would just cause the plaster to fall off after a while if it was in real use and applying painted this wall would have done absolutely nothing to stop the fire

Post 10 was plastered when he made this video. It’s nothing to lath about.
All joking aside, fascinating content. Totally didn’t expect the end result.

All plaster/gypsum contains "crystalline water" and it's why it feels a bit damp when you touch it before painting. If you have in back of a heat source e. g wood stove it will slowly disappear and at last be only as powder in structure. It's also why it has a cooling effect at start at fire. It's rapid changes in pressure (flashover) that makes overheated sheetrock to crack open. Double layer (2x ½") together makes it about 4 times stronger. In a fire dividing wall with 4 layers and a non-combustible insulation between it gives 60 min fire-spread protection (and a lot of sound proofing)!
*Nice to see testing this time also, Post 10! You're doing a good educational service to the viewers!*

"If it wasn't for all the sunlight, woah look at the I'm blocking the sun" made me chuckle.

anyone else want to hang out with Post10 and go on a small journey with him. Like I would love to go on a hike with the guy listen to him talk about all the stuff. Plus you could watch first hand the MAN, THE MYTH, THE LEGEND unclog a culvert.

You're right that the plaster has better mold/moisture resistance, but damn, it sure is a pain to work with lol. I live in a house build int 1902, all the walls are plaster, and it's impossible to get into them without a major hassle- or even just hang things. And you can't patch them it quick and easy like you can sheetrock. Then again... maybe the only reason my house is still standing after nearly 120 years is *because* it's built with lath and plaster!

I'm terrified of house fires. My mother had one when she was a kid and she raised me to be so careful with kinda paranoid, actually!

[vladshome]

not sure how i got here but this video was actually strangely interesting and informative. i had no idea plaster was so much more fire resistant. i learned alot about walls today

Wood prices are crazy!!!, Another great video!, Hats off to you!

Plaster is like real silk. Stronger than steel but so fragile. I told my bf, the house we live in built in 1905 will still be standing long after his aunt’s house built in 2001.

I love these kinds of science experiments. They're fun to watch and educational.

I finally understand why all those cartoon Tom & Jerry walls look like that from the inside.

[chrisgeorge]

So thats why my living room wall was cracked and bulging out. They didn't apply the plaster correctly and when we took it down to put in sheetrock, the lath wood had no plaster inbetween it.

Grew up in a house in the 1850's with horsehair plaster walls. I remember how the rooms were much quieter because the walls were thick. Thanks for showing us this.

I really enjoy watching this guy do his thing. The culverts are the best for me. Keep up the good work.

[floshey]

I love these, I hope you continue this series of building science experiments.

Would love to see a comparison of plaster and lathe with different additives. Source some horse hair and really do it old school!

Well you have just answered a question I have had for years . I live in a house built in the early 1800’s . I asked my husband to help me put up a shelf . Now I come from a very practical and knowledgeable about home improvements, family . As my husband came from the polar opposite I tried to encourage him by asking for his help . I had already marked out where the screws needed to go and had drilled some pilot holes but the height and weight of the drill was too much . I did say they were pilot holes and left him to it as although I knew what to do he liked to feel he was in control.
I came back when called and found out he had put in raw plugs that were obviously too big but had hammered them in then cut off the protruding excess . He asked for the screws and announced they would be too big and we obviously needed bigger holes .
Now this is the bit that I still have nightmares about but daren’t ever mention . I agreed that the screws came with the shelf so they were right and maybe I hadn’t made it clear that he needed to make the pilot holes bigger to fit the raw plugs . At that point, now annoyed as he thought I was being smart mouthed, he took the drill with a now bigger drill head and proceeded to drill the holes bigger . I shouted “No! Stop, the plug is still in the hole” . He reassured me that it was fine as he blasted the plastic raw plug and the plaster, only removing the drill when a large piece fell off the wall . He slammed the drill down whilst cursing the poor quality of the plaster in this old house and stormed off never to return to the job.
I left it and the conversation then one day when he went to work I bought the things needed, did the repair and put the shelf up with the help of a friend .
Now I can tell him that the lats were probably not done properly in that area and maybe he might give diy another go although I don’t think my nerves could take it as he thinks I’m always doing it ‘my way’ but really it’s just how everyone else does it .

Post 10 has videos to satisfy any audience including culvert and drain cleaning, nature videos, animal videos, and lots more

[katherinekinnaird]

I grew up in a 1959 laugh and plaster home. Yes it would crack . As always I learned from your video. Thank you.

[bicybic]

I feel like i got a college degree watching this. Thanks!!!

[michelechapman]

I love your channel so much! I came here for the culvert videos and have learned so much about lots of things. I love that you enjoy doing things the more naturally way instead of using computers. You show so much beautiful nature and teach us along the way. You need tons of sponsors lol. Thanks so much for sharing. I get so excited when I get a notification ... When YouTube actually sends them. I was surprised at myself that I liked the hike video so much but truly loved ever aspect of it.
