Floor prep pre tile install
I'm rennovating a bath. demo is done and I'm realizing I've got a proud joist / uneven floors. The middle of the room is high to the side walls by 1/4" on each side. I'm currently down to 3/4" osb. I've done enough DIY jobs to know prep work and a level floor is essential. However, not enough that I'm quite comfortable pulling the OSB out completely to shave down the proud joist and reinstall osb. Before anyone goes off about the mess of self-leveling compound, yes I know; I've learned the hard way already once and am proficient enough with it now. Yes, while not all self-leveling is intended to be applied to OSB, some stuff by Mapai is acceptable, provided you pre treat and prime your surface. I don't really want this to delve into discussions about the merit or process of self-leveling itself. Rather, my question is about if it is acceptable to perform self-leveling as a first step before tiling (my previous experience was before lvp install). I have already purchased my ditra decoupling membrane. Can I pour self-leveler, and then moarter on top of this to attach my ditra, before finally installing tile? From a height perspective I've run the numbers and I'm fine with it, just coming from an "is this acceptable" perspective. Alternatively, I've considered adding extra 1/4" osb in my very low valley's over top the existing osb and giving the edges a quick buff with a sander, and then simply going over everything with my moarter pre ditra install, going thicker in some areas attempting to get close to level when installing my ditra membrane. Seems less "propper" and more accident prone, but maybe there's some concern with bonding moarter to leveling moarter and this is actually preferred somehow? I would appreciate any insight you could give me. submitted by /u/Anne_8788 [link] [comments]
