Reply to comment by spinswizzle in Advice for first time drywall patch by astropiano1998
Certainly not inline with what the pros I’ve spoken to say. whats Your reason? It isn’t needed to get a flat finish. Is there another reason?
spinswizzle t1_izcg99e wrote
Where are these pros operating? What part of the world. Couple reasons why you sand. There is always going to be slight imperfections in the mud…these will break off as your adding your next coat
spinswizzle t1_izcgqyz wrote
Hit send by accident. The bits of dried mud will then cause difficulty in skimming the coat. Your also going to contaminate your pail. The next reason is really an extension of the first. Any kind of fast setting compound is naturally going to be tougher than your top coat…again A quick buff sand to take any bits of grit off is going to go miles in providing a super slick top coat. I’m 51…and I own a construction company. It’s literally what I do for a living. Every drywaller I know sands in between coats. If you don’t…you do not make money at it. Amateur.

Alright. You convinced me. Appreciate the knowledge dump. As an example of a source of my expressed opinion,, the Vancouver Carpenter on YouTube talks about not needing to sand. But again, you convinced me.

I haven’t checked him ouT. But a carpenter isn’t a drywaller. HavIng said all I have said….I suppose it’s possible to not sand a very small patch and recoat it. Not a great idea but possible if under duress. I do whole houses or hundreds of feet of cutouts at a time. The sanding between coats isn’t meant to be a grind down…just a buff. To make things easier. Bear in mind I’m only doing 1-2 coats after tape coat.

Old tradesmen Fucking hate change or doing things differently then they were taught.

Do you know how many people out there are trying to differentiate themselves by deviating their approach ever so slightly, usually adopting older parallel abandoned but slightly less effective methods? This is called ego and marketing and humans are sick with that stuff. There’s a reason things are done a certain way, and it’s a good reason. But this reason only holds if your source of knowledge isn’t a complete block head and is focused on doing things the right way for the sake of doing it the right way, rather than other reasons. Then there is also incompetence.

Lol keep telling yourself this. It is stopping us from saving the earth.
SnowyNW t1_izdg418 wrote
Are you kidding me? That’s the exact point that I’m trying to make is that all this needless deviation from historically proven traditions is causing terrible calamities such as the extinction of the entire biosphere! Plastic instead of glass and wood? Giving up millennia old forestry practices and causing historic and unnecessary wildfires? The earth is dead because we want to do things new and different instead of tried and true. You beat me to the punchline but somehow have the opposite point of view, I’m completely baffled to be honest. Traditional farming, building and social practices could have stopped a lot of this.
On the other hand humans are the most effective natural iterative design network the universe has ever seen.

You’re not saying anything coherent anyways

It’s to prevent debris and floaters when you skim. It’s not about being stuck in old ways it’s about production and high end workmanship that dOesnt need a ton of filling afterwards. Scraping a joint might work on small patches. Try that on a whole townhouse complex and watch yourself get kicked off site. Plus….I’m only 51. That’s not old. I’m still learning all the time And I’m the first one to do something new…if it makes sense.

I find, at least personally, a lot of carpenters over estimate their work and underestimate how bad it can look. I'm biased, but carpenters are the bane of my existence
Sunflowerslaughter t1_izd5nuc wrote
I do it professionally, doing work for the union in cleveland for a multi-million dollar company. You don't "finish sand" on bed coats, you do what we call a brush down. The goal is any lap marks or edges will be buffed out, which means it's easier to box over. Then at the end you finish sand, using lights and hand sponges to make sure it's smooth. Some guys don't sand and just cut edges with a knife but personally i think their work looks worse than just brushing it down.

I think the problem is that we are in a diy forum. What one homeowner or tenant may find acceptable won’t fly by industry standards. My company does a variety of different types of jobs. I used to do a bunch of restoration work but now I concentrate on larger jobs like rough carpentry for a new tower complex or installing appliances for same towers. When I do restoration work it’s larger jobs like dealing with the drywall issues in a hotel after mold remediation. None of the scrape down with a 6” knife would fly on any new tower project or townhouse develoment
Sunflowerslaughter t1_izfa8qc wrote
Yea, i tell people to brush down in diy work because it can be a pain to sand down a lap mark you coated over, and i expect lower quality work from diy home owners. Scraping down with a 6 definitely works okay for diy though.
spinswizzle t1_izfb9ug wrote
Yeah. What kind of houses are people living in. Here in Vancouver that wouldn’t fly at all. Our housing market is probably the hottest in North America right now. Cheapest most rundown house in Vancouver proper is over 2 million. People are always looking to flip their house and make a quick 100k. Everything has to be spot on all the time. And the homeowners know this so workmanship has to be top notch

Here in ohio when the housing market got wild we saw a lot of very poorly done quick buy and flips which looked awful, but still sold. One such house had globs of paint that they never bothered to sand down. It was a shit show. Some of the best finishers I've worked with come from doing houses, but also all the worst finishers I've worked with come from doing homes too haha.

It’s mostly wealthy asians and Indocanadians that run the market here. Very particular. Sometimes they’ll change the wall color as soon as your finished the whole job and ask you to re do the whole thing They always expect the world
