Taping cement board joints using a membrane

In this video I will show you how to tape joints using a membrane. There are several reasons that I do it this way and it is very simple.

There was a time when a person had to shadow a real person at work to get this info. Needless to say, few people gained access. I appreciate you taking the time to share your knowledge. Very generous of you. I will use this in my current project.

[@roncarswell8472]

This was an excellent video, I am went to find Hydro Ban and it is amazing. Thanks for making me look good, Wife is happy

[@annominous9567]

[@Sweatshirtlouie]

Was at a loss with the kitchen floor and bathroom walls and so forth..... asked/looked for advice on how to do this, since I have nooooo clue, most conversations went uuummmm no thats not the right way and explained something to me that involves a parallel universe. (Yes heard theme from Twilight Zone......a lot.....) till i found and your clips. thank u for speaking human, and showing how to fix uneven walls, floors, tiles, and straight up showing how its done! starting kitchen in 2 days with absolutely no fears or questions then bathroom. Never done this whole tile thing but, i will own it. Thanks and keep em showin

[@SoThatsHowYouDoThat]

Thanks Laura and good luck to you!!

[@selmooliveira4541]

Very good video! thank you sir.

[@ronaldelia9956]

Thanks for the videos, I've watched a few of your videos on transitions from drywall to backerboard and I really couldn't find many of these and none that I found as credible as yours! I used your info to do my transition from drywall to backerboard in my laundry room to make the transition level...next time it's drywall for me this backerboard didn't make it an easy transition and it's not a shower so it wasn't actually neccessary...but other videos made it look easier than it actually is 😬. Thanks again you got my sub!

awesome video very informative and thumbs up to your camera guy

[@SoThatsHowYouDoThat]

Ha ha! I will let him know! Thank you!

[@standleyb]

Great and informative videos. Please be careful with the dust if it is wallboard dust because it contains silica which can cause lung cancer. I would vacuum it with a HEPA filter vacuum, but don't breath it or blow on it!

[@alortiz5139]

Hey partner its me again just wanna say keep sharing these great videos..

[@SoThatsHowYouDoThat]

Thanks Al!!!

[@cwc8979]

SoThatsHowYouDoThat Why did you stop making videos?

[@louisehyde9503]

[@gms1958]

niiiice! I use the same technique when I make my showers!

[@texascrossbowdude636]

Is that product that you brushed on the same as redgard? Btw love your videos. I'm learning so much for my tub to shower conversation.

[@futurefarmer8]

I like your delivery, informative, to the point, etc. So, you don't use thin set to tape the CBU? I plan on using Hydro Ban - as I did a previous shower, great stuff - but I taped with thin set then three (3) coats of HydroBan. Overkill? I thank you in advance for any insight you might lend.

[@SoThatsHowYouDoThat]

What you are is good!

[@armandocantu7059]

Thanks for the informational video. I seen you do the taping two ways. Do I need to apply thin set on the joints first and let it dry before applying the waterproofing or can I just apply the tape and cover with waterproofing. What do you recommend. Thanks.

[@SoThatsHowYouDoThat]

A show both ways if time is an issue but the way I recommend foremost to go with, thinset over the tape let it dry and then apply the waterproofing membrane

[@roberthosenfeld6787]

I'm redoing a shower that has a fiberglass pan with a lip. I understand to stop the cement board at the lip. But when I go to tile what goes behind the tile and the gap that is created between the end of the cement board and where the tile rest? Can you direct me to one of your videos. Thanks

[@einfussganger]

Your vids are great - thanks for taking the time to make these. Hardi seems to indicate that corners and seams need the glass tape embedded in thinset, but you seem to skip this step. I just finished doing my shower Hardi's way and it's pain because the thinset is so THICK and I truly suck at floating tape - espectially in corners. You mentioned in one video that you had a trick for preventing the thinset taped joints from bulging, but I never did see that trick.

[@SoThatsHowYouDoThat]

Yes and they are on my website in my members area Tile University

[@alwayskksj]

Other videos say you should leave 1/8" gap between the cement boards to allow seasonal movement. Is that true ? Thank you.

[@SoThatsHowYouDoThat]

The only place I leave a gap is along a tub.

[@watchmanexpert]

That is to prevent cracking ? Someone installed tile in my bathroom and didn't put the tape and after 3 months the bathroom has huge crack on corner from the ceiling to the floor ,I put silicone to the crack ,maybe that is why the corner wall crack he didn't put the tape ?

[@AlexC-fm4tb]

You do a great job explaining things without dumbing it down like most other videos. To the point, but detailed at the same time. Tnk u. Do you have a video that shows how to remove a bathtub and then do what u did here? To make it into a shower. I'm scared with the "plumbing" aspect of it. Thanks. Ali

[@SoThatsHowYouDoThat]

Coming very soon!!!!

[@joshhiggins9453]

Do you need to put hydro ban in the corners over the tap? Or can you just put tap and put thin set?

[@SoThatsHowYouDoThat]

I use hydroban in the corners, but you can thinset first then hydroban.

[@Widgitmusic]

How do you expect that the curb will remain waterproof, when you use screws to attach the hardiboard, puncturing your liner?

[@SoThatsHowYouDoThat]

Fred I use a paintable waterproofing membrane. This stops all water at the surface, It never makes it into the pan which is much better. It does not mnake sense to let the water seep into the pan to get to the liner and then go to the drain. It will stop at the surface of the pan and mold and midew will never creep in.

[@vicpeletier267]

I wanted to know where you can get this product Hydroban. I'm from Ontario Canada if you could send me that I would appreciate it so much. Thankyou

[@PurplSugar]

Any reason why you put your wall board down into the shower pan? Wicking!!

[@SoThatsHowYouDoThat]

There is no wicking when you use a paintable membrane. This is not a pan liner shower system, it is getting hydroban which is a paintable membrane over the cement board and on top of the pan. I would never recommend a pan liner system, that is a terrible and old way of installing a shower.

[@wesrobinson7366]

I have taped and mudded my corners, then would apply the hydroban, is that overkill?

[@SoThatsHowYouDoThat]

No. You need the hydroBan to water proof.

[@Mrobertnoel]

Do you usually order the Hydo Ban online? I tried to find it at local home improvement stores but didn't have any luck.....And thanks for the video! Really useful!

[@SoThatsHowYouDoThat]

Yes buy it on amazon. I have links on my site!

[@gregb8931]

SoThatsHowYouDoThat

[@briangarscadden117]

I am building a shower and have been following your site. One thing has me confused. Hydro Bans site seems to say that a pan liner is required and you say no.

[@SoThatsHowYouDoThat]

No!!! There site does not say that at all!!

[@Eastbaypisces]

What do you do at the bottom where it connects with bathtub? do u tape that too or no?

[@SoThatsHowYouDoThat]

Yes I tape it then I applied membrane to it. Once that is dry then I fill the void with thinset and then I would apply membrane over the top of it once again

[@Methodical2]

I've see some videos where they use thinset on the tape and then the water proofing membrane over the thinset. So, it is not necessary to use thinset on the taped joints before using the waterproofing membrane?

[@SoThatsHowYouDoThat]

I show this method because I live in Northern Minnesota and it gets very cold and Tile likes to crack and using this method will prevent that from happening. Using the other method will work too.

[@Methodical2]

@@SoThatsHowYouDoThat Gotcha. Thanks...

[@gregoryhagar]

I made the hole around the faucet pipe a bit too big - about a half-inch extra radius all around. What are the steps for filling in this gap? Thank you

[@SoThatsHowYouDoThat]

Use cement board tape around the whole and then fill it with thinset

[@gusshelgoshiii1836]

Do you have preference( backer board )

[@SoThatsHowYouDoThat]

Yes for walls I prefer durrock and for floors I love using Ditra.

[@skull187a]

what type of thinset or material do you use to finish the durock to a smooth finish? also what do you use to fill in the in between the cement boards with the tape membrane? tnx in advance

[@SoThatsHowYouDoThat]

Hydroban. I use this on most of my joints in a shower. However if you gaps are larger than an 1/8 of an inch then fill with thinset frist then apply the paintable membrane. In this case I used hydroban

[@skull187a]

Thank you for responding to my question. Keep up the great videos and God blessed you and your family.

[@rodneyag54]

Please answer this question for me. Can I use metal beads on hardibacker for corners?

[@alwayskksj]

You prefer hydroban over redGard ? Thank you.

[@SoThatsHowYouDoThat]

Yes I do! Because Hydroban can be applied on a gap up to an 1/8th of an inch without using fabric. That should tell you right there how good it is.

[@Alex2007MUC]

Hello Sir, just a very stupid question. You just used the waterproofing membrane for the joints. Would it be smart to get the "green" membrane rolled on all over?

[@SoThatsHowYouDoThat]

That is not a stupid question. Yes I did roll the entire area with membrane I just did the joints first. Its in another video!

[@Alex2007MUC]

Thanks, haven't seen all your videos yet... going step by step. But thanks for the quick response.

[@CGphotoOp]

Help! I got ahead of myself and added waterproofing membrane on the joint where the cement board meets the drywall. Will joint compound stick to the waterproofing membrane?? Great vid btw, great job of explaining clearly.

[@SoThatsHowYouDoThat]

Yes

[@ricklane9556]

Is the thinset that you use for the joints the same as the thinset you use to set the tiles?

[@SoThatsHowYouDoThat]

Yes

[@ricklane9556]

Thanks, the mortar I am using for the shower pan is Quikrete mortar mix #110260, this will be fine for that correct?

[@SoThatsHowYouDoThat]

I would not use that. Do you have a tile store near you? A flooring store will usually carry what you need.

[@joshanimation6518]

I need to know a guy put blue board up then I primed and painting it can I tile over it now or do I have to put cement board on to tile ????

[@SoThatsHowYouDoThat]

If it's in a shower I would remove it. Otherwise use Kerdi made by schluter. It can be applied over sheetrock.

[@joshanimation6518]

we have a pre finished shower black pan do we put cement board on the edge of it ?we got the black pan from home depo the put red stuff on then tile over that would there be an over lap on it ?

[@drummermayne11]

to take care of the "dust" you should wipe it down with a wet sponge first before applying the tape or paint. great vid tho.

[@SoThatsHowYouDoThat]

Very true Anthony!

[@morganescamilla163]

i can used any cement o is one in special ?

[@SoThatsHowYouDoThat]

Wouldnt say that. What are u looking at?

[@anthonyromano8565]

This seems less expensive than all the material purchases needed for the Schluter system.

[@SoThatsHowYouDoThat]

It is but I do like the schluter system also!

[@noahraheem5277]

What happens if you don't tape and seal the joints before installing tile

[@SoThatsHowYouDoThat]

well i like to tape the joints to give added strength but it should be ok

[@pennysmith2012]

Can u just tile over the rock without doing this

[@SoThatsHowYouDoThat]

If you use Kerdi to cover the rock.

[@racheld8621]

In this video it looks like you put the cement board in and then did the shower pan. .......

[@SoThatsHowYouDoThat]

Yes. I am using a system that waterproofs the outside of the pan and not below the surface. It is a far superior method than the old way of letting the water go into the pan.
