Keep up the good work Andrew! Your videos have been very inspirational in my basement remodel.

[Lee_bonus_family]

Thank you, I didn’t know I needed to use a primer with self leveling.

Thanks for your well-produced and informative video. You made it look so simple that even "A child could do it." I would have liked your video even more if you had used a level to show me the before and after difference and what you spent on your project.

[sherirobison]

Loved your video. I had already applied the primer and didn't read the directions. I didn't water it down. I applied it straight. Will that cause a problem or just take longer to dry?

[paulschmaltz]

Good advice Andrew. I have an uneven sloping concrete floor that feathers from zero on the outside walls to 2 1/2" in the middle where the bathroom is. It's about 12' from the outside wall to the. I had to take up the 5/8" plywood subfloor, along with the tar paper and old lamenated wood flooring, and now it has to be put back. The previous owner shimmed and shimmed and shimmed. Is there an easier way? Thank you.

Just curious but after self leveler, did you actually check with a level? I thought self leveler needed to be in the majority of the area, whereas it looks like you filled only the really low area and there was still a high spot from the existing concrete. Thanks!

[PulpMatter]

No subfloor inbetween the concrete and lvp?

[JoshOutdoorsGR]

Any tips for drilling the closet flange into the self level concrete?

Hi thanks for the video is it possibule to level floor in to session in too days all the best Hannes

Unfortunately, I haven't done it in my office, which I know I probably should have done, but I've already attached the baseboard and vinyl plank, and I don't want to remove it. There's a sump pump behind that corner, so I've thought that maybe it's better that way to help out water drain in case of a flooding and I can manage to work around that uneven corner which is about 1 inch out of level. Had to cut baseboard in 3 pieces to make it work, but once I say that it ain't going nowhere, then it won't 😂

Dislike the video after min 2 of “self leveling” 😂😂

[jacomuller]

Bro where was this video 5 hours ago. I just epoxy'd my floor and unhappy with the result

[ncooty]

Would've bonded better if you'd removed the paint.

Those plumbers just don’t know how to reinstall concrete properly
