- In this video I show you how to tape and fill cement board joints(both cross joints and the beveled joints). I also show how to prep the inside and outside corners and we will discuss how to deal with where cement board and sheet rock meet.
Here are the links that I talked about in the video -

Simple, clear, and straight to the point. So many other videos distract from what is going on, or over explain things. Thanks man
getting psyched up to do this in my wife's bathroom.. started off as "would you please recaulk the tile in the tub?" and turned out totally gutting the bathroom, removing 1975 linen closet and throwaway hall closet to expand the room.. now tiling floor to ceiling, installing new counters, sink, mirrors, floor tile, soaker-freestanding tub, and on and on.. had to do lots of rewiring, new plumbing (sigh). and we live out in the country far enough that finding someone to do the work is next to impossible and twice as expensive. So, despite years of construction experience, never liked floating and never worked with thinset, so been putting this off. After seeing your video, it almost looks like fun! Thanks for your video, and using your phone, the video quality was just fine. New Sub! Thanks,again.
Thanks for sharing!
Taking on a tiling a fireplace. This is what I was looking for. Thanks for sharing.
Thanks a lot man, your videos helped me get through it. Definitely the best finishing cement board videos out there. THANK YOU!
I agree with Jason Silva. This is the best video I've seen. The guys told me to use corner bead but I just couldn't make sense of it. Do all that work and then have rusted corner bead.
Appreciate the info about transitioning between sheetrock and cement board. Nobody else seemed to cover this, thanks!
Getting ready to put stack stone on my island and this really helped me tyvm again. It helps to watch someone who knows what they are doing.
Thank you!!! Been looking for this kind of video all day!
Straightforward, succinct, professional, subscribed
I just can't imagine how this could have been done any better. Stressing that a "divot" is better than a hump is so key. I was also thinking about how to transition 1/2" green board into .42" Hardie Board and extending the Greenboard beyond the tile line makes all the sense in the world. A+ piece here!
I always learn something from you. Awesome
😎✌️
Mixing and product information would have been a good addition.
About to tackle my first cement board taping and thin-setting. Your video was super helpful and gives me hope! 😆. I'll be looking at more of your videos for sure as I go along in this project - thank you!!!!
You got this!!
From one believer to another, thank you for a very well done video that is helping me through my bathroom renovation. Keep up the good work, love the witnessing in your videos.
Awesome! Thank you!
Thank you for doing these videos!
Yw and thx for letting me know you like them.
This should work for my fireplace!!! Thanks!
That was a good tutorial. Thank you man.
Beautiful technique
Great demonstration
Precisely what I was looking for thanks
Glad I could help
Thx bro. Appreciate the help. God bless
Thanks. Good instruction.
Thank you for the video!
Great presentation. I'm in middle of doing this now and this cleared up what direction I need to go. I was thinking originally running loctite polyurethane sealant on inside joints for expansion and contraction in a very old house on post and pier. I have shored up floor as I added alot of weight with mortar bed under acrylic pan. I added studs and 3/4 ply to single wall construction to beef up. I think thinset and mesh tape will be good for filling seams and screws prior to waterproofing.
Hi jack. Thanks for making this vdo for showing the tricks. Appreciate if you can make and post more and more vdos on cement board projects. Since there are very few vdos on the internet. It helps us the people like me.
You got it!
finally a video that helps :D thank you!
Glad it helped!
Hi Joe. I really appreciate your no-hype tips and common sense approach to teaching these techniques. It's not rocket science but definitely requires demonstration and practice. Words don't teach as they say. No two jobs are ever the same, is that right?
Yeah that is very true.
Great video. Thanks.
You are welcome!
When you have tape with less than adequate adhesive (I taped the joints, but when I returned a few minutes later, half of the tape was lying on the shower floor!) A friend who was a drywaller suggested I use some spray corner adhesive for drywall. I sprayed it on, let it get tacky and the tape stuck!!! Crappy tape at HD. Both rolls I tried were brand new!
I've always used the red guard to tape ( fiberglass mesh) an bed all joints instead of thinset gives the walls the ability to flex without cracking joints.
I agree and I have another video sharing that - th-cam.com/video/fCVD91BnrVc/w-d-xo.html
Nice!
Thanks for this 👍🏿
Yw
Perfect.
Thank you for your help
You are welcome!
thnx for sharing
Do you tape an inside corner where cement board meets drywall or just let the tile hide the joint? If you do tape do you thinset one side and drywall compound the other?
Hi Joe/Joel? Sorry didn't quite catch your name. Thanks for the video. I have hung my cement board unfortunately I have a small area in the corner where I have not made it quite square. There is a gap almost 1/4 inch. Can I prefill this with quick set then tape over and mud again? Or I need to take it down and redo it? I will also be using liquid membrane with mesh fabric over the corners.
Great video
Glad you enjoyed it
Thank you! Very helpful. One question - are you using the same thinset that you would later use for tiling?
Yes I am
Question 🙋🏾♂️ what kind of thinset do you use on the duroc?
Good video
Great thank you so much.
You are welcome!
thx for the tip!
You bet!
awesome
Thanks!
Could i use type 1 premixed thinset over taped cement board joints? the white stuff?
I tried this with mortar and once it dried you can just rub the mortar off of the backer board completely with your hand. Is this normal or should I have used a modified thinset?
Thanks for taking the time to post your videos. Clean, clear info for us weekend warriors. We're at this stage now; hung the last cement board last night and ready to tape/mud. Curious... we took cement board up and will tile to ceiling (existing sheetrock). I assume we use the same cement board tape for the ceiling joints, but use drywall mud instead of thinset?
Yes, I would. But, if you go to the cieling you really do not need to tape that joint. Just use a bead of silicone at the ceiling.
Thanks, mudding my bathroom today
Good luck!
Thank you for the Tips. Very Helpful. Best Always. Via Con Dias
Glad it was helpful!
How does one transition from cement board to drywall if later installing a sliding glass shower door?
Do you put waterproofing on after this or will this serve as waterproofing?
What are you using for thin set?
If you get too much thin set on your joints can you stand them down?
Can you use durabond instead of thinset?
So what if I'm only having to do 3 ft.up from a soaking tub and then I have a shelf at either end due to our plumber putting our drain in the wrong place.
So can I use Easysand90 (or any other setting mud) for the cement board to sheetrock transition as long as I use a roll on waterproofing membrane within the spray zone?
Yes you can
Hi. Is ok waterproofing after or before
I saw another guy put silicone caulking on all joints is that necessary
How do you handle an outside corner or ceiling that meets drywall???
Thx so much
No problem
Thank you so much! I love that there is grace when doing this! I have a question, I did my thinset on my tape but after it’s dried there are little “holes” from the tape. It’s like the cement dried and it’s under the tape and the holes on the tape are showing through, but you can see the concrete set under it. I think I mixed my thinset a little too thin... Should I do another coat of thinset or will my red guard take care of these small holes?
Yes it will
you can use silver set joint compound on these joints where your tile will be thinsetted in?
Yes you can use that
What can I use to tape greenboard inside a shower. Thinset or drywall mud? Ii have 2 feet of Greenboard on the top of the wall
I would not use green board unless you cover it with Kerdi Membrane.
Hi. Is ok to waterproofing after I applied the mortar on the joint and on all surfaces? Please answer thanks
Yes
Amen!
Thank you. So, alkalai resistant fiba-tape for the joints, right? I'm still trying to find the right thinset. I read that the cementboard needs a modified thinset that meets certain standards. I think it means it has latex or something added.
Question: What if I am not doing tile? I plan to use a glue-up fiberglass wall set over an existing tub. The wall set will not go up as high as the board so I want to paint over any portions that stick up above the wall set. Any suggestions on that front?
Should I put cementboard all the way to the ceiling or let it terminate at 5' above the tub? My wall panels only go up about 54" so there will be about 6" of cementboard above.
Also, how would you handle corners that go from cementboard on one side to printed plywood on the other? I will probably cover the corners with some sort of trim, but I want to make sure the cementboard edge won't crumble.
Question - why are you running the cement board past the ending of the new surround? I would end a couple inches before the top of the fiberglass.
@@SoThatsHowYouDoThat Its thin glue-up surround and I have to glue it to the cementboard but I also need to fully span the studs and get to the end of the alcove since I will be removing the existing plywood panels. although, I suppose I could leave some portion of the plywood panels, but I would still need to bridge from cementboard to plywood. The panels are probably not the same thickness as the cementboard. This bathroom was made by idiots who put carpet in the bathrooms, cut entirely through the joist under the tub for the trap, and had non-waterproof plywood surrounding the tub.
Great video. I’m learning a bunch. Thank you. I’m building my tub surround with Hardie backer. Does it matter if I use modified or unmodified thinset when I tape and fill the seams? I’m planning to use Aqua Defense as the waterproof membrane.
Depends on the hardie backer , look in the pdf of the specific board instructions. Either will blend to the drywall ok, just make sure it is the right thinset for that kid of board. If not, then you can’t get a good stick. I used the hydrodefense board, and Custom Building Products FlexBond mortar bc it works with the board & is more flexible when dried so I won’t get as much cracking. Good for changing environments, best out there
(For begginers)
What brand of cement joint do.you use for patching?
USG and I like the green stuff the best. Home Depot has some decent tape. Buy the more expensive tape, it is worth the money and it sticks the best.
On another of your videos, I think you used the HydroBan membrane to tape the inside corners - why did you choose to use thinset on the inside corners here instead? I'm about to put up the concrete board and do this myself... thanks, your videos are VERY helpful.
It can be done either way, your choice. I usually use thinset then hydroban.
Immediately subscribed and liked for mentioning JESUS in the intro! 🎉❤
Not only are you a good teacher, the Jesus saves message was why I subscribed
How come you arent staggering the corner joints, i thought four corners are never suppose to come together
No this is just fine.
What type cement are you use ?
That is durrock. The thinset was ardex
Thank you! and John 3:16. !!!!
I'm assuming your thinsetting with cement?
Yes, that is correct.
Is that a cement board approved mesh tape? It’s supposed to be gray. The regular mesh tape will fall apart because the acid in the cement board will eat it away.
Not all cement board tape is gray they do also sell white. Most are becoming gray now but that's not how it's always been.
Some people are looking for information on whether to use modified or unmodified thinset. Who doesn't know how to tape a joint?
Use modfied thin set.
What cement you using for join??
I am using a modified thinset
I LOVE the shout out to Jesus @ beginning of video :)
you should not use this regular mesh tape, there is special mesh tape for bathroom , the grey one/
No tape?
The tape has a chemical in it to prevent the cement board from eating thru it over time. God Bless
How much of a gap is too much of a gap?
There really is not too big of a gap because it can be filled with thinset.
@@SoThatsHowYouDoThat I really appreciate your response. Thank your so much. Do you have a recommendation for thinset to use? Or what you normally buy? Just curious as to what other use
I'm learning a little something but I couldn't hear while you were scraping and talking
Sorry!
Yes, Jesus is the Savior. Rely on Him alone for salvation. Not ourselves. He paid the price with his blood.
Amen
Thumbs up just for the mention of Jesus as our saviour.
I have been saved now as a Christian 53 years I got saved 1969 thank you for mentioning the need for people to know the Lord
Is Jesus Christ going to finally show up and help? My bet is no...
😎✌️
