DIY Plaster Repair Part 2

[Wubamac]

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.

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

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

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.

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.

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

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

[RickFlairWoo]

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

[TheBMXisReady]

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

[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

[benpainter]

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

[JayBreeze]

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

[ronemtae]

You should spray the bare wood with water

[ouimetco]

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

[jameswillis]

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

[cainjake]

Get a bigger trowel save yourself so much effort

[FrankSanchez]

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

[helloweeny]

That’s definitely not how you do this.

[stevecam]

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