So heres todays question: How do youself-level a bathroom floor, specifically a basement bathroom that has a concrete floor?Well, in this part 1 video, were going to show you how to prep the concrete floor.And then in part 2, well show you how to self-level it. Many videos may leave out someof the small tips that are really important for this type of bathroom remodel. So basementbathrooms, a lot of people have them. But if you do it the wrong way, it can lead toa lot of big problems. So lets show you this first video on how we prep the floor.And then in the next video, well show you how we self-leveled it.Okay, so this is a basement bathroom. This is kind of a typical situation where the flooris completely unlevel. They obviously designed this original concrete floor to drain towardsthe drain in the middle of the floor.So like a lot of basements, theyre just completelyuneven. So to be able to set a tub in this scenario, you have to level everything. Imtypically saying if its more than a inch, then you want to address the levelness.Anything more than a inch is going to make it very difficult to set your tub and do allthe tile work and get everything level. Anything less than that is not a real big deal; youreable to shim things up or when you set your tub in mortar, you can play around with that.But anything more than that, it becomes pretty difficult.So to show you this scenario, this scenarios pretty bad.And say this 4-foot span here,were about an inch out of level, this being the high side. So were going to floor levelthe entire bathroom floor. And the first thing you want to do is establish where the highpoint of the bathroom is. We know that this side is higher than the right side here. Solets see which side of this side of the room So it looks like our high side isall the way in the corner over here. And then lets just see what and this is slopingdown pretty bad as well. Its almost an inch and there.So in this corner, what we do is use some Tap Con screws. Now, you can use other typesof screws, but these are easy to sink into the concrete.But what were going to dowith this is place these so that these tops of these heads are level, basically givingyou a marker for where to pour the floor to. Floor leveler is great. If you just want tomake something smooth, you can just pour it out and just feather it out. But if you wantto make something level, you cant just pour it and trust that its going to sitlevel. Youre going to have to have some indicator to make sure that that leveler fillsthe whole area that you need. So were going to go ahead and put these Tap Cons into severaldifferent places so that when we pour the leveler, we can fill them up to the top ofthem. So on this back side, Im just going to actually just get this screw all the waytight to the floor, and then well be basically filling like a inch on this top part.You need a hammer drill and a concrete masonry bit to drill through the concrete floor.Nowsometimes these bits come with a Tap Con kit. So well just have the floor level go tothat height, and thats what were going to indicate everything off of to make thingslevel. So from here And you only need probably like six differentplaces in the bathroom to ensure that youre level. So we put something over here. So justgoing off the top of that level part. Actually, Im going to go up over here. Thats prettybad. Im going to get a longer screw. So thats the top of our thing here. Thatsabout an inch and a half.So thats quite a bit of floor leveler. If you just pouredthis without having this indicator, theres no way that you probably fill it this much.So this is going to be our indicator. So as long as you get that floor leveler to thetop of this, youd be good. So we just continue to move around the room,drilling holes into the concrete floor and adding our Tap Con screws. So again, you justwant to check with the level that your Tap Con screws are at the right height. You mayhave to adjust the height of them and check that theyre at the appropriate height withyour level. So were just working our way around drilling all those holes into thisbathroom floor. Okay. Go back and to this front corner.It is important to get these Tap Con screws at the right height, so take your time duringthis process. It may take a little bit longer than you expect, but thats okay.Okay, so thats level. So for this bathroom, we just worked our wayaround the room in a counter-clockwise fashion, adding all those Tap Con screws and ensuringthat theyre at the right height.Looks good. Okay.The next step is to Shop-Vac the entire room. You dont want any dust or debris on theconcrete floor because were going to have to prime the floor. In this case, wereusing the Prime-N-Bond by Laticrete because were going to use Laticrete self-leveler.So I recommend the night before kind of preparing this, you have to use a primer that goes overthe entire floor associated with the product that youre using. So were using Laticretefloor leveler. So you want to use their primer the night before or, you know, a couple ofhours before. Im just going to see what it says 2 to 5 hours before.So 2 to 5 hoursbefore, apply this primer. Its going to be easier just to do it the night before.And then in the morning well go ahead and pour the floor leveler.But to prepare for the leveler, I recommend using a latex caulk. As you can see here,I built a little trough area to keep the floor leveler going into our drain area. You kindof want to protect any area this is going to flow. Any area that water can flow intosomething you want to be able to seal and keep that floor leveler from seeping out.So were going to just use some latex caulk around this little box that I created here,and this should keep any floor leveler from sinking into my cavity. I also recommend goingaround the entire floor area and filling this in. And again, this is just preventing thatfloor leveler from seeping underneath this wall.Its not a bad idea to tulle the sealant with your finger to make sure that itscompletely compressed up against the wood. Okay, so then wipe down your whole surfacehere just with a little bit of water and get all the dust and stuff off the floor beforeapplying the primer.So this is just a pink foam that is for asill plate. You put this down, like say youre framing this wall over concrete, you wantto put this down underneath the framing. But Im going to use this as a spacer, basicallygiving us an eighth inch gap around the edge of the room, so when the floor leveler fillsup to this, then were going to have a little bit of expansion and contraction area betweenthe walls. You wouldnt want to just pour all the leveler straight to your framing.You want to give some kind of space for expansion and contraction.So were just going tostaple this on. This is like a 5 inch piece. But once all the levelers done, welljust cut the excess out afterwards. Ill just tack it up around the edge.Were just tacking the foam to the studs using a stapler. You can actually tack itdirectly to the drywall if you already have drywall installed. Its not a big deal because,like Steve said, were just going to cut this foam out from the wall once were donewith the self-leveler. But this is a critical step because it provides that important 1/8inch expansion and contraction joint between the self-leveler and the wall.So again, were using the Prime-N-Bond by Laticrete. This is the Laticrete primer fortheir self-leveler. Were just using a 3/8 inch nap roller to roll it onto the concretefloor.Youre going to want to get every inch of floor covered in the primer becausethat way your leveler will stick to the floor. If you dont use a primer, you run the riskof the leveler not sticking to the concrete, and that will be a huge headache. So whateverleveler youre using, use the accompanying primer that is made by the same company. Soif youre using Laticrete self-leveler, use their primer.The next videos going to show you how to self-level this basement bathroom floor.Whenwere done with that, well put it right here for you to watch.
