DIY Plaster Repair Part 2

[@Wubamac6776]

I was a plasterer and finish carpenter for over 25 years. The way lath works is the structo light or base coat has to go inbetween the lath and catch on the backside in order for the plaster to be attached to the ceiling. If there is old plaster inbetween the joints, like there is in this video, and you do not remove the old plaster inbetween the lath before putting a base coat up, all you are doing is putting a coat over the lath and it is not adhering through the lath and curing on the other side to create a solid piece. The next time you do a patch like this, make sure you take a spackle knife or a 5 in 1 and knock all of the old plaster through the lath, so that all of the lath is open, then start your scratch coat. You’ll never have to patch it again, if you do it this way.

Yup. My first job-mixing lime in a mortar box with a hoe

[@markme4]

I did not know that and it makes perfect sense, thank you

[@connormcindoe6993]

I'm glad someone commented with the correct way of doing it, hurt my eyes watching this

[@kona702]

I noticed this right away as well. Definitely has to go through the lath to hook on the backside. It might hold. It might not. But more than likely it will eventually separate years down the road.

[@rebicul]

Do you recommend removing the insulation and any plaster that’s above the lathe before starting to apply plaster weld and basecoat?

[@andygarcia3585]

You could also hang drywall, mesh tape the joints, easy sand the patch with at least 2 coats, then sand down the patch.

[@reymundofigueroa3866]

Looks way better

[@rrpinsanfrancisco8598]

I’ve owned a couple of homes with plaster and not sure if I agree with his patch method. I’ve stapled screen mesh to the lath to prevent further cracking. At least it looks like he wet the lath.

[@yolisurich4025]

Structolite works good on first coat . Then you can use drywall mud.

[@huejanus5505]

I’ve done hundreds of repairs like that in old houses. Use 1/4” or 3/8” drywall to patch or fill the bulk of the hole first. Makes for a more solid repair.

[@michaelsanchez5023]

We use 3/8 or sometimes 1/2 blue board

[@sonnyguadagni8738]

Screw to the lathe ?

[@lestalkmorebasss]

@@sonnyguadagni8738yes, screwed into ceiling joists wherever possible and also lathes at edges

[@sef2273]

Behr paint says it has primer and paint in it. Do I need a primer also?

[@12341234Joao]

No final or mesh tape?

[@lestalkmorebasss]

No bonding agent?

[@JayBreeze890]

Am I missing something? Aren’t you supposed to secure in a steel mesh? Not sure how secure ceiling plaster on wood is.

[@davidkramer333]

You have to push it in hard enough to key it in. That is how all plaster ceilings are held up

[@marke4576]

Little tip. Use spoung to wet the wood before applying plaster.

[@Guardducks]

A bigger trowel would save you some time , but with that being said using a bigger trowel takes getting used to, but you do and it makes a world of difference.

[@DanSoloPlastering]

Nice try but sadly won't last. You should have raked out between the lath like the picture on that tub of patching plaster

[@benpainter5384]

You have to wait minimum 2 months before you Primering. With this process

[@TheBMXisReady]

just plater it properly the english way that would crack with any movement because the lats are flimsy

[@RickFlairWoo5]

I’d just use 20 min fast setting compound works great 👍🏻

[@ouimetco]

Do not wet the lathe. It needs to suck the plaster into it for a tight bond.

[@connormcindoe6993]

Wrong, dry wood will suck out all the moisture of the plaster and can cause it to crack. He should have removed the old plaster from between the lathe and made a new mechanical key for the plaster to hold.

[@ronemtae3468]

You should spray the bare wood with water

[@ollie9506]

That looks well grim

[@tomashekerua3090]

Is he serious? That will Crack %100

[@helloweeny5541]

That’s definitely not how you do this.

[@lincolngolladay]

I’ve done a lot of remodels in 100 year old houses. This is an okay way of doing it. We would always use 5 minute mud, lay it on, then sand it over in 20 minutes.

[@jameswillis8349]

I mean I'm no expert but I would of cut some ceiling to size and just patch the outside maybe 🤔 🤷

[@barryallenporter8127]

You’re not gonna find drywall the same thickness as plaster. When patching plaster you chip until you find an area where the keys are all intact

[@jameswillis8349]

@@barryallenporter8127 maybe so. but I do have bad eyes that didn't look like plaster to me I could be wrong I normally am wrong Haha

[@FrankSanchez505]

Everybody look where the light is and where he shows us. It looks really shitty where he did it. It's not easy hire the pros

[@jfart127]

Most people will just cut a nice big square hole and put a new piece of drywall’

[@stephenalford3026]

Old Florida has sand in the finish

[@KiXa1]

That's not how you plaster ..

[@emkay7486]

Most people can not do this - and that is a big opening for just mud.

[@TheCraftsmanBlog]

But it’s not just mud. It’s patching plaster. It was designed for gaps this size.

[@stevecam2109]

And you got paid for this?? Like oatmeal he said stick to making breakfast

[@e.v.frederick3598]

Very cool.

[@grahamwarford5452]

Make the hole even cut a board to fit. Scrim it and plaster it..this was a poor attempt .

[@johnjohn-ne8fw]

Maybe it's me but that doesn't look smooth 😕

[@andrewferrari6411]

Come on mane, I’m a painter and I patch all the time, bub you didn’t even sand it🤦🏼

[@cainjake7940]

Get a bigger trowel save yourself so much effort

[@ziggiesaquaticexotics8270]

Use 20 min could have done it all in a hour but also clean out those keys man before you try n plaster it cause it looked like all your keys was filled with the old muck still no bueno senor mas esquala

[@maikheinrich1468]

Klasse

[@renostubbs8504]

Nice

[@luisgastelum7550]

I could not have done a better repair myself limited materials and canceled orders maintenance life

[@s1krr696]

No lath wtf definitely don’t do this

[@supercleanone8038]

Zero percent keying, hundred percent fail

[@stoopidbastid6420]

Or just mount some sheetrock, tape and mud and be done 2 days ago or at least used lath. Leave it to a Moronnial to make a simple repair into a major project. Do you know anyone smart?

[@lincolngolladay]

It’s hard to make the drywall height match and look right. Generally we use 5 minute mud to get it done fast.

[@bigshow94066]

Right.put some drywall and 5 min mudd.couple coates and your done

[@benpainter5384]

I can see bubbles in your project

[@alibertylover]

I just use bondo

[@edwardelric8354]

It’s coming down soon

[@chrisvail7844]

Definitely make a square hole first then 3/8 drywall then mud and tape

[@mrbuster7255]

Rough rough 🐕 🐕 🛷

[@TomTomTomTom538]

Wow that looks terrible I'd be so embarrassed to post such crap work online

[@TheCraftsmanBlog]

Wow, my mom said it was really good. But hey thanks for your feedback! That really helps!

[@vasiliychinikaylo8553]

Brah you can clearly see where you did the patch.

[@bigshow94066]

What a waste of time.put a piece of drywall then mud it sand it and your done.then you dont waste 2 days.people shouldnt be putting videos up if they dont know the best way to do things

[@rhyswelburn5111]

No
