Really there are three common types of 5/8 drywall, plain 5/8 drywall, Type X 1hr fire rated, and Type C which is a very heavily glass reinforced drywall that exceeds a 2hr fire rating intended for use for ceilings in commercial building, and recently they have come up with a 30minute fire rated light weight Type X drywall.
Green drywall is moisture resistant. Purple drywall is moisture *_and_* mold resistant. The Home Depot in my area no longer carries the green variety, as the purple variety meets both requirements, thus it simplifies their inventory.
I would remind you that any drywall that gets wet will dilapidate and grow mold. Moisture and mold resistant drywall is very overrated but it is required by code in many instances. Thanks for watching!
I just bought a house in McAllen, and the master bedroom wall had a hole knocked open by door knob and I noticed the drywall is paper thin. What's the paper thin drywall?
I am having a tough discussion to make since I am building my home on which material to use for walls and partitions. finally I have two option to chose from either to use gypsum boards or to use concrete hollow blocks, I am leaning towards gypsum boards but every body worns me about sound proof capability. I really need your scientific advise, by how much sound proof is better when using concrete hollow blocks rather than using gypsum boards?? Please advise
I'm not sure I understand your question. Concrete blocks as opposed to wood framing with drywall over it are two totally different scenarios. Concrete blocks would be more sound proof but provide a totally different interior appearance.
@@drywallinstruction1766 yes it certainly provide different appearance, but 2hat I want to know is how much is the difference in both ways in a scientific figure. For example I know gypsum board douple layer would provide sound isolation up to 30 DB but I dont know how much hollow concrete block whould provide??
Do you have a preference for any particular brand of drywall? I know a couple guys who insist on Gold Bond from National Gypsum. As a painter I find the paper on Georgia-Pacific's drywall has a finer grain than others I have used.
I personally haven't seen a great difference in brands. I use what is available at Home Depot because of the convenient location to where I live, it's a quick stop en route to my projects. Right now that happens to be USG. I have noticed that some brands can be more brittle and difficult to score and break but haven't noticed a big difference in the paper.
@@drywallinstruction1766 Local availability is important. I can get USG and Gold Bond delivered to my jobs and I have no preference between them. The only minor issue is the tapered edges are slightly different but if you don't switch brands halfway through a project it doesn't matter at all. My only experience with G-P's product is painting it. The primer did not raise the grain of the paper like other brands. I have no experience cutting, hanging or taping and finishing it.
So I did this job that was remodeled in the 80’s and they used nails in the ceiling ,so I went back and put screw in and skimmed the whole thing. When it dried it turned yellow what’s the deal ? Edit : was there moisture it look like it reactivated the compound because the taped parts were even darker yellow
Not sure exactly, sometimes chemical reactions happen. Rarely does it affect the integrity of the mud. I would seal it with a good product like Kilz2 and you shouldn't have a problem. I'm guessing it's not a moisture issue.
Anything you can find that is water or mildew resistant. Basements tend to be damp and can develop mold issues, for this reason I believe there is some paperless drywall so there's nothing organic for the mold to grow on. Mold needs 2 things, water (even vapor) and food. If finishing you're basement try to not use anything organic if you can, such as standard framing lumber. If using standard framing lumber, the bottom plate should be pressure treated and rated for ground contact. Just don't use it throughout the entire wall as most, if not all, building codes will prohibit this due to the chemicals that can be released during a fire. Hope this helps.
Nice video but Sheetrock is a brand name. There is no such thing as "Purple Sheetrock". You are referring to National Gypsum's XP. Think Band-Aid and Kleenex. Sheetrock is the brand name from USG.

Thanks for your time and efforts. I learn something new every time when I watch your videos. Liked and subscribed. Keep spreading the knowledge.
You're Welcome!
I'm learning a new trade, so I'm doing research on drywall and repair. Video was very helpful. Thank you.
That's awesome, drywall repair is a largely untapped market. If you're interested in learning more contact me @ info@drywallinstruction.com.
Guys, pls can someone tell me what is the difference between gypsum board and sheat rock? for me they look same and so does the procedure ? thanks
Same thing.
thanks

Probably a hokey repair.
Good information. Thanks

There's a plasterboard in Algeria with colours green white red and yellow I want to know what use for red and yellow plasterboard

What kind/type of drywall should be used in a basement?
1/2" drywall is typically used in basements.
Anything you can find that is water or mildew resistant. Basements tend to be damp and can develop mold issues, for this reason I believe there is some paperless drywall so there's nothing organic for the mold to grow on. Mold needs 2 things, water (even vapor) and food. If finishing you're basement try to not use anything organic if you can, such as standard framing lumber.

Thanks man
I had no idea that sheet rock and dry wall was the same thing... huh
Do you have tips on sheetrocking walls up to 54' in height?
would be perfect if we could actually see it
Nice video but Sheetrock is a brand name. There is no such thing as "Purple Sheetrock". You are referring to National Gypsum's XP.
Think Band-Aid and Kleenex. Sheetrock is the brand name from USG.
Thanks for the clarification. Brand name aside, for as long as I can remember people use drywall, sheetrock, wallboard, etc. to define the product.
Sorry, bad grammar. Meant to say "people have used the terms drywall, sheetrock, wallboard, etc. in reference to the product."
Why knit pick? You know what the hell he means
Don't be a dick... if you ask for sheetrock in the stores you will get drywall... bitch
Agreed, like "Sawzall" to describe any reciprocating saw, call it what *it is* not what's *easy*
