Hanging Drywall Ep.106

[Music] welcome back to our spec house series in this episode you're going to watch a lot of drywall go up about 13 000 square feet of it in fact we've got darren sutton and his helper jack on the job and if you watch this video and the next one you're going to know a lot about their trade and you'll start to finally see the rooms of this house begin to take shape drywall is sort of thought of as more or less the halfway point in building a house and let me tell you we are happy to reach this milestone and have you along with us the first thing i want to mention and point out is that all of the measuring and fitting that's done when you're installing drywall is done to the eighth of an inch in fact when these guys are communicating measurements back and forth to each other they will only refer to inches and eighths of an inch for example twenty and four would mean twenty and a half inches eighteen and three would mean eighteen and three eighths inches hundred and twelve and six would be a hundred and twelve and three quarters of an inch etc bottom line since every single cut is going to have sheetrock mud troweled into it in one way or another an eighth of an inch is plenty close enough and way easier to keep track of [Music] if you watched our episode about insulation you'll remember that this stuff in the ceiling is not stapled or fastened in place in any way it's simply wedged in between the ceiling joists and friction is fighting with gravity well as you can see over time it begins to sag and if enough time went by it would end up having fallen right out of the ceiling onto the floor so darren and jack are pushing and lifting the insulation back into place pushing it up before they put the drywall where it goes it's a problem for those guys but i've got to say right here and right now that darren's attitude about complications like this was uniformly positive he always just put his head down and kicked out great work [Music] [Music] so [Music] the paper on the front and back of the sheetrock is important for several reasons and it's a different paper on the face than it is on the back on the back it's a lot thicker and so it's a lot stronger the front paper is very smooth very even and takes primer very readily now structurally the paper is acting sort of like rebar acts in a concrete slab it's providing tensile strength the drywall itself the rock itself the white stuff is providing the compressive strength that's why when you're cutting this you simply score the paper on the face and flex the sheet at the line snap just like a saw cutting a control joint in a garage floor now some sheetrock will come with a mold inhibitor in the paper some comes with a glue that activates with water whatever kind of sheetrock you're installing you've got to be sure to keep it dry because there's not much that's more frustrating than cutting and fitting and hanging soggy sheetrock [Music] so [Music] you see this nifty little cordless router that's that darren is using to make all these detailed cuts however hesitant i might be to switch over to a cordless skill saw i'm all in on this little beauty it's doing for darren what in most cases is unthinkable in handwork that is it's increasing speed and accuracy at the same time this is as clear a case of cordless beating corded as i've ever seen a cordless screw gun router and utility knife is a great 21st century combination [Music] [Music] [Applause] [Music] so i can remember when drywall screws first started showing up on the jobs they were an immediate game changer for several reasons first they held so much better than nails you know they would pull the sheet right back right up against the framing without the same tendency of fracturing the sheetrock with the hammer blows and second they set up a situation where the sheets could be tacked into place with nails by the experienced guys and then later all the screws could be put in by the newbies because the screw guns would set the depth of the countersink and so the screws would stop at exactly the right point and so even a beginner could do a good job with just a little practice the fact is that a screw is a better connection with far fewer problems later on than nails but those first few nails will always be important to get those sheets in place when time counts in some areas and on some jobs the building code requirements for different lengths of fasteners for different thicknesses of sheetrock are strictly enforced as well as the nailing pattern or the screwing pattern for those fasteners so be sure to check your local codes before you wade into your project in general around here the fasteners are an inch and a quarter long for the half inch drywall and an inch and a half long for the 5 8 with nails on seven or eight inch centers in a single nailing pattern and screws on 12 inch centers single [Music] nailed [Music] so [Music] do the first thing is to hang and nail off the ceilings and then butt the walls snugly up to it not super tight but you know in contact as you can see being able to work together with your partner and anticipate what's about to happen next is critically important because just like every other phase of construction hanging drywall is all about handling the material efficiently now it's really easy to make more work for the tapers by being sloppy when you're hanging the drywall because it takes extra time to mud in big gaps right but it also is easy to make more work for yourself by trying to make your cuts too tight because about as many times as not you've got to take it back down and cut it twice darren is one of very few drywallers around here who both hang the rock and tape it and frankly he's doing a beautiful job a good rule of thumb is that an eighth of an inch of slack in your cuts is just right and anything over a quarter is just plain too much [Music] so this is green board or water board and it's a good idea to put it in any part of your house that might be you know damp high humidity it is not waterproof don't make the mistake of thinking that this is waterproof but it is mold resistant the paper on this on this product is less prone to promote mold growth than on ordinary drywall but here's the bottom line water is a problem if you have water loose in your house you've got much bigger problems than any piece of drywall is going to save you from so don't think of this as being [Music] waterproof [Music] do [Music] do so i've already explained that in residential work 5 8 rock is standard on ceilings right well 5 8 type x drywall is also required on any one hour firewall which is always the wall between the house and the garage and sometimes includes the walls and ceilings under stairways usually a firewall must be nailed seven inches on center to studs that are 16 inches on center with all the edges penetrations and joints taped and mudded you might be interested to know that there is another fire rated drywall it's type c and it's more fire safe than type x there are a lot of ways that these fire rated products can be applied to achieve different levels of fire resistance in your structures and it's always a good idea to talk to an engineer or your local building official about what they think you ought to do if you have a question about fire safety an inner part of what you're building [Music] usually the idea is to always hang the biggest sheet possible thereby reducing the number of joints and butts that have to be taped but on the other hand you don't want to waste material which means using scraps when it makes sense this is always kind of a trade-off between saving the money by using what would have been a scrap or spending the money on a bigger piece of drywall to save the time it would take for the extra tape and texture and as a bonus if you do this it can make a flatter wall for the finished carpenter to fit to on the back end of this job now after hauling a lot of rock to the dump and seeing the finished job i'm of the opinion that darren got this trade-off exactly right [Music] do [Music] as you can see now this really is the very last chance you have to correct anything inside these walls before they're covered up with drywall so if you haven't done it already maybe bring your kitchen cabinet specialist through or maybe a home automation person heck maybe even your tile setter so they know what they're working with and can let you know what they're going to wish you had taken care of before the drywall went up [Music] [Music] [Music] the need for a smooth sanitary interior surface on the walls of our houses has been a reality to be dealt with by builders for a long long time in many parts of the world various plasters have been used since antiquity to make this happen the house that i live in today was built in 1924 and has lath and horse hair plaster on the original walls and ceilings it was an incredibly labor intense process by today's standards and it is absolutely miserable to deal with in any sort of a repair or remodeling project as it turns out drywall was invented in 1916 by the u.s gypsum company but it took decades to catch on as a quality building material it was thought of as being cheap or shoddy because after all how could a product that was 10 times faster be anywhere near as good right in fact it wasn't until after world war ii that it really began to dominate the construction industry and by about 1960 or so give or take drywall was king [Music] i hope that you've enjoyed watching darren and jack put this stuff up and in the upcoming episodes you'll get to see them do the next steps in the drywall process processes that are more art than science and they're known as tape and texture the next video in our series is going to show the part of the process that is referred to as tape and texture and it's radically different than hanging and completely dependent as far as how long it takes and how hard it is to make it look good on the job that the hangers did thankfully the hangers did a perfect job thank you for watching essential craftsman and keep up the good work [Music] you
