An unofficial chapter of the popular Dull Men's Club.
1. Relevant commentary on your own dull life. Posts should be about your own dull, lived experience. This is our most important rule. Direct questions, random thoughts, comment baiting, advice seeking, many uses of "discuss" rarely comply with this rule.
2. Original, Fresh, Meaningful Content.
3. Avoid repetitive topics.
4. This is not a search engine
Use a search engine, a tradesperson, Reddit, friends, a specialist Facebook group, apps, Wikipedia, an AI chat, a reverse image search etc. to answer simple questions or identify objects. Also see rule 1, “comment baiting”.
There are a number of content specific communities with subject matter experts who can help you.
Some other communities to consider before posting:
5. Keep it dull. If it puts us to sleep, it’s on the right track. Examples of likely not dull: jokes, gross stuff (including toes), politics, religion, royalty, illness or injury, killing things for fun, or promotional content. Feel free to post these elsewhere.
6. No hate speech, sexism, or bullying No sexism, hate speech, degrading or excessively foul language, or other harmful language. No othering or dehumanizing of anyone or negativity towards any gender identity.
7. Proofread before posting. Use good grammar and punctuation. Avoid useless phrases. Some examples: - starting a post with "So" - starting a post with pointless phrases, like "I hope this is allowed" or “this is my first post” Only share good quality, cropped images. Do not share screenshots of images; share the original image.

That whoever is going to be me
Look how they massacred my boy!
I can do all sorts of DIY things around the house.
Drywall/plaster, I am terrible at. Much respect for those skilled in the trade. Their work on a ladder above their head beats what I can do at eye level over 2 days.
(The other thing I don’t touch is plumbing. Jeez, that water really wants to be outside of the pipes. Unlike drywall, the impact of bad plumbing is much more than an eyesore.)
It is actually just as hard as it looks. Not only the act of plastering itself, but knowing which products to choose and how to use them correctly. It seems simple on the surface, but it's an art in itself.
Yep. Have a lot of respect for people who know the right materials.

I see what you did there
As another DIYer for mudding and taping, what I've learned is that less is more. Better to do 5 wafer-thin passes with virtually no sanding than 2 passes and sand like a sumbitch because it's full of bubbles.
This is a good tip, thanks. I have been approaching it with a "I'll build up a ton, then sand it back to what I need" which is probably one of the many ways I mess it up :)
That's how I started out, too. Not only does it take forever to dry, it'll crack and slump. And then, of course, there's the interminable sanding.
You can also play with the later coats, going with a thinner consistency so it fills the little holes better and you're scraping most of it off. Watch a few youtube channels of pros, it's time well spent to save time later.
Same. Drywallers and plumbers are Gods in my book.
Well I'm plumber by training so this finally confirms the belief I've had about myself all along!
Plumbing is way, way easier than drywall (in fact I would go so far as to call the supply side of it "easy," including soldering copper pipes); it's just that the penalty for failure is so much higher.
I partly agree and partly don't.
Plumbing as a field is way broader than installing drywall, and there's a ton to learn. No single plumbing task is really harder than hanging drywall (except maybe welding), but doing all the drywall in an entire building is a hell of a lot easier than doing all the plumbing for it.
I'm only talking about DIY plumbing a single-family house, and I only said the supply side was easier. The drain side is more complicated to understand, with the slopes and venting and whatnot.
Probably sitting in a corner somewhere.
Keeping someone warm, because they are always 90 degrees.
I think that’s the right angle to look at it.
I got a corner trowel and didn't care for it. It's hard enough to do one side evenly, and even harder to do two at once. Plus I just ended up with lines at the tool edges.
I'm just an unpaid DIYer, though, so I can more afford to be patient about drying times.
(BTW, since we're talking about drywall: I found "Vancouver Carpenter" on YouTube to be super helpful in teaching good technique.)
Not all imperfections are created equal. I don't worry about ridges because those sand away with few passes. It's the parts with too little mud that I need to re-fill that I try to avoid.
that, as they say, is a skill issue
unless your wall is wavy as shit, it should be pretty easy to find the right angle as a little bit of practice
also you have the feather the edges in after still, just like you would with a single edge tool. it's not gonna get rid of that unless you're really good

See, that's the part I was expecting the corner tool to make easier. If I've got to feather the edge with a normal knife anyway, I might as well just use the normal one for the whole thing.
but then you have a sharp internal corner
if that works for you, then yeah no point using this
There's also the fact that the tool is 90 degrees but corners rarely are.
that's what changing the angle compensates for

Also, use this stuff for corners, its a game changer IMO
Thanks for the tip - I might give it a try. They seem to be selling a similar product in the local harware store. I use steel corner beads on outside corners but with inside corners I've just prefilled and then taped with paper tape just like all other joints.
Yeah its a nice product and the difference is the metal inside corners keep nice and straight if you dont overload with mud. Just dont buy from Lowes! Fuck box stores and their flock camera corporate operations
This stuff right here. Game changer is not exaggerating at all.
Fuck Lowes
sure, idc where you get it from, it was just easy to find and share a lowes link.
Srry for cussing. Its personal with Lowes. Just add a disclaimer.
How well is it gonna work if the corner isn't a precise 90 degree angle? I didn't even realize how imprecise corners were until I got a corner desk and it didn't sit flush in any corner of my house.
I'm a big fan of the corner trowel, but you'll still need to bust out the putty knife at the ceiling where the three inside corners meet. It takes some practice and finesse, but you can get it nice without needing to wait for any of them to dry. Having a knife that's deliberately a tiny bit dished so the corners don't dig in helps (and is super handy in other places too)
I recently had the pleasure of realising how tricky corners were myself and was unsure if this would be a gimmick or game changer. If I ever get held at gunpoint and need to do this again I will grab one of these.
