3 Easy ways to SEAL TORN DRYWALL PAPER!

welcome back to vancouver carpenter you guys so have you ever tried coating this stuff and found that it all blisters up as soon as you try and paint it or re-coat it again yeah it's a real headache and today we're going to try out three different methods for repairing this stuff just so you have more tools in your toolbox because i have made a video about my favorite way to do this which is using shellac primer we will do that but we're also going to use two other things that might surprise you the first thing we need to do is prep all of these and these are brutal these are exactly the kind that even if you like scrape them off and prep them and like just try and mud them these are all gonna blister let's take a look at them all right so yeah we got this nice big one right here we can see there's like loose paper there everywhere it all has to get glued back down this one's pretty nasty too this one it's all got like the de-laminated paper this is the only one i bet you if you just mudded over this one after scraping those loose spots it would be fine but most of them are just those awful ones where the paper has just separated in multiple layers glorious not too bad not too bad horrible horrible so my intended products is yeah we're gonna do shellac to see how that works because we know it works then we're gonna do um 3m super 77 spray adhesive this stuff works really well in a pinch it also dries real fast and no moisture seems to get through it so it's a really good option and the last one usually i avoid anything water-based but i have found that just straight wood glue will actually do the job the first thing we need to do is get these all prepped and it can be a bit of a task you kind of want to get under it with a knife and just kind of go until it decides to stop and it's pretty tricky to make sure you've actually found that some people like to carve around it with a knife to get a nice solid edge and that works but i don't like it because you score the drywall the paper and i don't want to score the paper yeah that needs to come off some more like this is going to be a blister for sure right here if i don't get this layer off it's hard to know where to stop and it always winds up bigger than you expected which is why using a knife can help but i think we're just about good there these edges all seem pretty sound you just gotta tap on it and if it sounds hollow then you have to do more work if it sounds secure then it's good so this is still no good i can just see it [Music] it's a bit of a technique kind of got to get under it and then work your way back i won't deny it's a headache okay i think i can live with that that's good enough so now i'm going to take care of all of these off camera because i know that was pretty painstaking it took a long time and i don't want to subject you to all of that on camera okay the first one that i want to try is the super 77 i mean i've used this a bunch and i've never had a problem with it as long as the paper is properly prepped and i really want to try it on this nice big one there is still a few little bits of loose paper but i think we'll be able to solve those hopefully this is like the bottom of the can oh good we're still getting some okay hopefully there's enough to actually do this and so it doesn't need too much and what i really like to do you might want to have a sacrificial knife on hand but i really like to then make sure that i'm getting it underneath all the loose bits of paper also the thinner you make it the faster it's going to dry this stuff dries in minutes so i do find it's a good product but this will just really lock everything down and if we still have any left in here let's try another one let's do like the first three or four oh you guys can't even see the other ones so the downside to this method is that it really does um it makes a bit of a mess see all that extra stuff i have on the knife there so i mean you don't want to let it drip down the wall because then it's going to be harder to coat this stuff doesn't really sand so if you make a mess of this and leave a bunch on the wall then you have to um you're going to have to coat it to make it disappear like if there's a big drip running down the wall your only option to actually get rid of that is going to be to coat it with mud so keep that in mind if you build it up too much it's going to be a headache and also you're going to have to coat all of what you sprayed anyways because it's a little bit rubbery and i don't know how that's going to paint out but if you're just looking to quickly patch this stuff and be able to coat it in like 15-20 minutes it's a good option like right now it's already tacky the adhesion is great for mud so no problem there anyways let's get on to the next one i'd say for the next one let's try the wood glue okay so for the wood glue what i do is i just put a little bit on a putty knife like this it's the same general idea the main thing is you just don't want to like over saturate it make it super wet this is one that i don't actually i've tried it a few times and i've had success but i don't know if it's gonna work guaranteed so i try and make sure that i actually take all of it off i'm making a mess on the wall so that's one thing we can say right off the bat is it's a little bit on the messier side the other thing i don't know is what the mud will stick to i should say if the mud will stick to this really well or if the glue is going to end up being slick when it's dry so i would recommend sanding this a little bit yeah the glue is definitely messy so this is more like if you need to do something in a pinch but the other thing about the glue is it dries pretty quick but not right away there's no chemical drying thing going on here like it's not acetone or shellac so it dries quickly like quicker than a latex paint but not really quick and let's do this one last one with the glue this big one here just so that we really can see if it actually worked or not so definitely the glue has a tendency to spread out a lot i hope you guys will forgive me if this one doesn't work out then my thumbnail or my title will be wrong it won't be three methods it'll be two that work and one that doesn't okay now let's leave that and last but definitely not least we have the bin shellac primer so a lot of people like to use spray primer for this stuff and personally if you're spray priming it i would still either use like a putty knife or some sort of a brush to wipe it into all the little nooks and crannies because you need to glue down all those little loose flaps if you're just spraying this stuff over top of the paper it just it doesn't really saturate and lock stuff down it just sits on the top of it so i like to use the stuff in the can and i will usually roll it on if i have a lot to do but what you need to know is that whether you're brushing or whether you're rolling you're going to be throwing it out after you're done because this stuff dries really fast and you can't clean it up with water so this is a crusty old brush on its last legs and let's put it to use one thing to be aware of is this stuff is like brushing milk it's so thin so it's really easy to be messy with it by accident i want just a little bit more on there but yeah this stuff just soaks in like it has the consistency and soakability of something like water which is why it gets in there so well but then it dries up really fast and because it's not water-based it doesn't reactivate whatever the glue is in the drywall paper brushing is definitely a nice method for getting this stuff in there and all those nooks and crannies okay so these are all dry now and there's only one that i'm a little bit concerned about and i'll show you guys the one i think might fail this big one seems great nothing wrong there that one seems good that one's good it's this little one and this was a spray adhesive one can you guys see this little bit of paper i think another layer of paper needed to be peeled off of this one let's listen to it i've got my mic right up next to it and now right here that could just be the contact cement sticking to my finger but it sounds kind of hollow to me whereas the one next to it sounds totally solid the wood glue one is the hardest this actually is like super hard listen to this the shellac one just sounds like regular drywall now a little bit against my better judgment i'm going to sand these really quick just to knock down a few of the high spots but i actually don't want to sand it so much that i get back to the bare paper again but this one the gluey one i kind of wanted to make sure that the glue has just a little bit of a scuff to make sure the mud sticks okay mud time i got some 20 minute mix pretty thick so that it i don't know just cuz do i have to explain everything i guess i do that's the youtube channel i got it mixed pretty thick so that there's less moisture that's going to go in here and cause me any grief right if it's really thin and runny it's more likely to put moisture into any weak spots that are still existing that's why you guys sorry i was being too lazy to explain it so no problem so far okay here's the one that i'm worried about the suspect one i'm gonna add just a little bit of extra mud on top of that one what that might do is just uh give it a thicker layer that won't bubble as easy okay this is the glue the wood glue so it's been about an hour that's how long i decided to leave everything and the last wood glue so that and this is just some wall damage that i needed to repair [Music] the shellac's for sure the best the uh the paint goes on so thin and i already know from past experience that it works all right guys this is all i had a chance to set up and as i expected the one that i thought might have a blister underneath it did and you know what there was another couple of ones under the shellac primer that actually have something going on but don't take my word for it let's shine a light on it and tap the wall a little as expected the 3m spray adhesive did really well so these aren't blisters it's just some inconsistencies in the mud i think so as you can see there's nothing really going on here that sounds good this one's really good but this one very clear we have a blister exactly what we don't want to hear and honestly all the rest of them are pretty solid like there really isn't much to complain about this is where we get into the shellac it's all doing pretty good i think we have no it's all a little bit right there but i can't see it so i don't think it's gonna cause me a problem and nothing there either so the shellac did well okay now let's not forget though the wood glue is actually really a shining star in this one and that was the one that i didn't know how well it would do but it dried surprisingly fast it dried really hard and yeah it it's doing really well so most people are gonna have wood glue on hand so it's a really handy quick solution but i do need to emphasize this isn't something i've done all the time i usually use sherlock so if the wood glue fails well i'm sorry but you know what if we want to talk about products that claim to do this but fail we can't not mention guards i guarantee you there's been so many comments already in this video what about guards i've made a whole video about that i've never had good experiences using guards it has always made the paper delaminate in way more spots than it should have we can see though that there is sort of an acceptable failure rate like on that one that i did the uh what was that spray adhesive basically i just couldn't tell that there was another layer of paper that had to be removed it can be really hard to catch all of it when you have a whole bunch of these to repair when you're just doing one whatever but when you're doing a whole lot of these it can be hard to miss them so when you've missed them and you don't want to have to go to cutting it out and scraping it out and doing all that stuff what can you do well what i usually do is just build the wall up a little more and as long as it's in a pretty inconspicuous space it's going to be okay if it's like you know a big ceiling or a well-lit wall you better carve it out and fix it properly but in this case i'm never ever gonna be looking at it again when this is done so we're just gonna bury it and if you guys were wondering why i was using these two funny little knives like this little ace hardware knife is because all my tools are on a job site right now so i had to mix up the 20 minute on this piece of plywood and here i have some straight out of the box um oh no this has definitely had some water put into it at some point i thought this was straight out of the box all purpose but no that's that's been mixed up so this will be good for coating that great but i'm gonna have to do it two knife style so first of course you're gonna want to give any of your mud either a quick scrape or a sand this is kick set that's kicked off but it's not actually dry so the only thing we can do is scrape it that's what i usually do anyways in this case and now let's get some of that soupy mud over these patches and see what happens this is silly having to work like this but you know what it can be done because guys i want to actually get this like finished sanded and painted because you know what it's one thing to show people what to do but not show your finished product i want you guys to see what this looks like and if it actually passed the test all the way to the finished product what do we got in here some little crumbly i don't think i'm gonna make this perfect because i am actually still going to paint this wall at a later date but i want it to at least be passable for you guys that's going to be good enough there's a little extra meat on there but there's no porosity and bubbles so it'll stand out pretty well and here we're getting to that problem one so i'm just gonna load this with a little extra mud basically we're gonna make it just a little bit thicker on that spot and some people go bend but then your wall's not going to be flat dude drywall finishing it's not flat anyways okay the whole thing is about building up little humps in the walls to try and hide the fact that there's joints remember that this is the silliest way to do this but i'm getting it done you know you don't always have to have all the tools get it done with a couple of knives piece of plywood you know you've got to do what you got to do to get the job done get a little more from down there put it there so yeah you don't have to build it up quite this much but like i said there's a little bit of insurance in building it out this much because you aren't going to see any little blisters if they do come through it's going to be way less likely okay i'm almost there almost there that's good enough we'll sand that lift off later okay the camera angle is way too lame for you guys to try and watch me coat that one so whatever okay let's get a look at this you guys so i mean it's looking pretty good and that's not as much mud as it looks like on there i mean we can still see that through there over here it's a little thicker like i mentioned i can't see that thing blistering through right now it's looking pretty good you know stays relatively same thickness into the corner a lot of liftoffs that's what you get with a five inch knife but hey i'm pretty happy with it all right it's all dry ready to sand okay time for paint look at this roller it doesn't even fit on this thing i'm just gonna leave it like that so i'm not necessarily expecting this to be like a perfect finish because i only did one coat of quick set and then one quick skim that wasn't exactly a skim it was pretty loaded but my point is this is to illustrate the effectiveness of the sealers not necessarily my absolutely ideal finishing skills dumb little thing i'm not even going to bother setting up a tray oh i got paint in the roller oops this is gonna be a mess all right you guys this is all dried and now that i don't have the light shining on it it's looking great it feels good let's check out some of these problem areas and show you how bad of a job that horrible little roller dead okay we got the glancing light down the wall and so first up this is actually just like a wall defect it's not a blister that's just something i didn't skim i think the patch was further out over this way but that's looking great so as we can see the spray adhesive is awesome it really did its job right here that is not a blister that's just something else like it should have basically had a thicker coat of mud to actually make that go away but it's not a blister and moving on from that i am actually trying to find the spot wait there it is so that's actually where the blister was i can hear it under there but i can't see it and that's because i built it up with like an eighth of an inch of mud so sometimes even when you think oh no there's a blister and all my work is lost you know you can build it up a little bit and hide it again so that's a little tip for you guys it's all looking good so there's nothing to see here at the shellac based repairs not sure what this is something on the wall like i can't even find them this is just didn't sand enough how about this that's something but i'm not sure what it is anyways overall i mean it's looking perfect look right into the corner there's nothing there it all works so now you guys have two more methods for repairing that torn brown paper i should say two more over top of the one video i already made a long time ago about the shellac but yeah i'm super happy about how well all of it worked so you know what now you have the tools and the know-how to get yourself out of a pinch and remember that you can build it up a little bit more if you're getting some problem blisters right if you can afford to in that spot which i easily could there i feathered it down you know about six inches you'll never see that so there's a lot of ways to get the job done hopefully this video was useful to you if it was you know feather that like button and i just want to say thanks for watching vancouver carpenter hope you guys are doing well and i hope your project's going awesome thanks for watching until the next one
