Practice English Speaking&Listening with: Schluter-DITRA Over Wood in a Bathroom (Part 1) - by Home Repair Tutor

Difficulty: 0

Before I head inside, let me explain what were going to be doing here. Were going

to show you how to install Schluter DITRA on wood plywood. So in this video youre

going to get all the tips and tricks that you need to do this yourself. And in the end,

weve got a really cool offer for you if youre going to be remodeling your bathroom.

So stay tuned until the end because I think youre really going to like what we have

to tell you. All right, lets dive into the tutorial right now.

Were going to go ahead and install the underlayment for tile on a wood subfloor.

Since Ive been using this process not only does it make the floor waterproof, but its

considerably faster and easier. And the technology behind this product ensures that your tile

isnt going to be subjected to expansion and contraction of the wood youre going

over. Now there are some things you have to consider

before installing any tile and knowing what your joint spacing is, knowing the thickness

of the wood that youre applying it over. Ideally, if its plywood you want to be

at least ¾” thick. Now there are some engineered specs. If youre going out 24on-center

and youre using stone, youre going to have to thicken that subfloor for deflection.

But on a typical install, if youre doing porcelain tile, ¾” subfloor or standard

16on-center joint, this product is going to be perfect for you. It makes it very easy.

Its called Schluter DITRA. And basically this is just an uncoupling membrane that Ill

be adhering directly over the plywood, and then the tile will be installed over top of

this. Thinsetting this to the floor, and then thinsetting the tile to this. And the ideatheres

a lot of theory and technology and engineering put into this productbut the basics are

that this separates the plywood layer from the tile and allowing just normal expansion

and contraction of that wood to not transfer through the tile.

So its better than putting a cement board down. These days if you put cement board down,

youd almost want to still put this over top of it. But not only does this help keeping

that transfer of expansion and contraction, but it also is waterproof. I mean, whats

better than that? I mean you have your toilet overflow or kids are making a lot of splash

in the tub, having this waterproof gives you confidence and peace of mind, and its not

going to ruin anything below it. Theres way too many times that I pull up a toilet

and I see the wood totally rotted around that whole area. Now granted it probably has to

do with a lot of the toilet leaking itself, but if you used a product like this thats

going to keep that from happening. So theres a lot of advantages of doing

it. For me personally, its so easy and light. I can cut it with a utility knife.

Im not inhaling any dust by cutting all that concrete board. I dont have to screw

anything down; Im just thinsetting it. So its a very easy product to install.

So theres a couple of components that go with it. Its the actual membrane itself,

and these come in all different size rolls. For this little bathroom area, you can probably

just get a 50-sq-ft roll and be fine. It comes with the KERDI Band. This is exactly the same

stuff that we used for around the tub surround to waterproof the joints of the KERDI Board.

So you want to put this over any seam in the corners of the room and wrap that up the wall

so that you have a nice, waterproof, tight floor. And you want to use the KERDI Fix.

This is primarily to fill the gap between the tub and DITRA. So well show you how

to install that. And then Id say one of the very important aspects of this is using

the right notch trowel. Schluter makes a trowel specifically for DITRA. Its 1164; its

basically 3/16square notch trowel. This will make adhering this down to the subfloor

the proper thickness. And another great thing about it is if youre using a correct notch

trowel, not only do you get a nice, flat surface, but you can immediately install tile over

top of this if you wanted to or try to attempt to install tile the same day you put the underlayment

down. Most other products youre just not going to be able to have the time to do that,

especially if you use cement boards. Its going to take you half a day to install that.

And by the time you get to doing the tile, its usually past the time you want to work.

So well go ahead and put this down. Its a great product, and well show you how

easy and simple it is to do yourself. So

the first thing you want to do is just to dry fit this down. And the rule of thumb is

basically trying to keep a ¾” reveal between the edge of the floor and the DITRA. And Schulter

recommends thisand this is especially important to stay within their warrantyyou want to

have an expansion joint between the edge of the floor and the DITRA itself. So when youre

dry fitting, just keep that in mind; and thats around all areas. Against the tub as well.

Keep a ¾” gap between the tub and the DITRA. Now Im just going to rough cut this before

applying thinset. Okay, so the first you want to do after you

have your first piece dry fitted, is to make sure your surface is all clean. Take any of

the drywall mud that might be stuck to the floor. Anything that can possibly jeopardize

the thinset thats going to adhere to the actual plywood. So make sure your surface

is clean and dust proof. I mean dust can actually keep that thinset from bonding to the the

plywood. And what you want to do to apply the DITRA

to your wood subfloor is using modified thinset. So make sure whatever you buy or whatever

youre looking at purchasing, that its going to be modified. Now thats what you

want to adhere down to the subfloor. And to keep that layer of thinset from immediately

getting dried out from the plywoodbecause plywoods mostly wood, I mean its obviously

wood, but its dry. And as soon as you put down that thinset, you dont want it to

suck the moisture out of the thinset too quickly. So just take a damp sponge; it doesnt have

to be soaking wet. Well just wipe down your subfloor, in the areas that youre

going to be putting this DITRA. So this will also take any dust off. You just do a quick

once over prior to installing the DITRA. Okay, so when I mixed this thinset, I made

it very loose. It wants to kind of fall off the trowel. You want to try to apply the maximum

amount of water to your thinset says that it can do because you want to have this very

thick. Just allowing it to spread this out and be able to adhere it to the DITRA correctly.

So Im going to put a bunch out here. The first step like any tile setting is to

firm the thinset into the soft surface. So just taking the flat surface of your trowel

and just working it into the plywood. I usually just do an area of arms length in to get

that full area. A little more. So just get that layer thinset down, and try to comb everything

in the same direction. And then, make sure you have that ¼” reveal. I just have a

regular grout float that I use to apply pressure to it and put it in place. First time youve

done it, I mean youre going to feel for it. If you use the right lodge trowel and

you just did what I did, you get quick coverage. You can see about 80% of this covered, and

thats what youre looking for. So just make sure you have good coverage.

We said 80% coverage in the video, but try to shoot for 100% if you can. That just ensures

that the DITRA is completely embedded in the thinset.

Okay, so with the right lodge trowel, using their DITRA trowel, you can walk on this afterwards.

It wont indent. Sometimes if you kneel on it a little bit, you can in some areas.

But if youre using the right lodge trowel, its not going to sink too much. And obviously

for floors pretty level, its meant to be walked on immediately afterwards. Do the same

thing on theas you continue. You might be wondering what Steve is doing

here. Hes pounding in any loose ring shank nails. Always a good idea to do that.

Okay, so you just want to butt this straight up against the other piece of DITRA as close

as you can; it doesnt have to perfect. But remain with that ¼” gap around the

room here. Its a little tight around the corner here,

so Im just going to take out a little bit of DITRA to get that ¼” reveal. And again,

you can just pull some of this out and make sure youre getting the right amount of

coverage. Actually, I think we have a blind spot right there. So I want to make sure I

have…. Then you can just use whatever you have left,

too. I mean it doesnt have to be a full piece. You can put as many pieces together

as you want. So in this little mock-up that we have here,

obviously we dont have a toilet flange where we need the toilet. So since this is

the mock-up, and its just the basic product, we didnt have that put in here. But really

that is just as simple as cutting around that flange, keeping that same ¼” reveal around

the flange. And then youll be able to use the KERDI Fix to go around that toilet flange,

and itll keep everything waterproof up the toilet flange.

Now obviously, I mean, this is waterproof to a point. If your toilet does overflow,

theres obviously areas around where your bolts connect and everything that water can

get down and below the pipe. So this isnt meant to necessarily be able to take a shower

in this room, but its going to keep the majority of the water from splashing out of

the tub to some basic water issues from absorbing into the plywood.

All right. So that is how you install Schluter DITRA on a wood subfloor. This is actually

a part 1 of 2 video. You can watch the second video right here, and that will show you how

to completely waterproof the DITRA in a bathroom. Now herewhat I wanted to tell you about.
