The first step is to accurately measure how much water is needed for the NXT self leveler. This is critical because if there’s too much or too little water NXT won’t perform – and that goes for all self levelers.

Pour water into a large mixing barrel and add NXT. Wear a silica dust respirator to protect lungs. Mix per Laticrete’s directions then immediately pour NXT over a prepped and primed concrete floor.

We needed 6 bags of NXT for this basement bathroom and used a floor squeegee to help it spread evenly. Add enough NXT to cover the floor screw indicators. Wait 24 hours or until the leveler has cured then it’s okay to set a bathtub or tile the floor.

  1. I have a non flat balcony and am wanting to level it to install tiles. But I do not see how you create a fall to a drain with this technique? What happens in case of a flood? Burst pipe?

  2. Great videos guys, the one thing I did not see addressed is the toilet flange. I can not find any videos on what to do with it. Do I take it up and level to the pipe or leave it and build a dam around it? Thanks for the awesome how to videos.

  3. Are there any slab temperature considerations on installing leveler? Ie winter new build house that doesn't have heat…

  4. Is it necessary to use self-leveler in a basement if the floor is already level? For an upstairs bathroom, there is a kind of cement board for floors.

  5. How to you account for the abrupt step at the bathroom door made by the leveling concrete? Looked like it would be fairly significant once the tile was installed. Great video, by the way!

  6. Your videos are awesome! Thank you very much. I really do appreciate your work. Quick question: When using self-leveling concrete, do I still need to add a mortar bed for the bathtub? Also, can I use this self-leveling concrete over a wood floor to level that? Thank you!!

  7. Im in the same position self levelling my bathroom, I plan on using Ditra DUO and tile.. however im confused on how I will transition to carpet over DMX air flow. I did my SLC with blocking in the door like this video… would it have been better to put blocking strip outside of the bathroom and put cement within the door area?
    Can I get your advice for a normal door and pocket door if the SLC process for that area differs? (Right now if i use pocket door.. the tile would end inside the bathroom with a bit of carpet which may look weird?)

  8. What's min/max thickness of this self leveling concrete? NXT brand is highly recommend or others good enough?

  9. What about the difference in height, how do you transition that? I have that worry in my bathroom, that's why I'm asking.

  10. I noticed your tiler was setting the long tile along the path of the trowel lines, wouldn’t you get better adhesion if you set the tile across the trowel lines? This would allow more air to escape as you set the tile, correct?

  11. You didn't talk about the door transaction, I notice it chipped when you took out the 2×4, what happens with that?

  12. Hello HRT, question along the same route: my shower (tile bottom) is not level, and has a crater not where the drain is leaving a pool after every use. Any tricks/materials that could help fill this in?
    Thanks!
