How do you self level 150m2 in different batches?

Just following this up with a thank you. Managed to prime (Uzin pe360 1 X 1:1 diluted chat plus 2 X neat) and pour all but one room (used as storage and dammed) this weekend. Son mixing and me spreading and rolling. Used a homemade depth gauge set at 3mm and it worked well for moving the SLC around. More drying out without the ufh on for a day. There is one area where the roller left a few slightly raised dots and another where I had to join two areas that had a bit of time between them going down (due to the layout of the ground floor). I presume that I can just grind them down gently with a higher number diamond pad (400 grit)? Otherwise, so far it looks consistently smooth and level. There are a couple of pin holes too that I will take care of.
Thanks to Adam for the Murexin CA20 - it was quite easy to work with and flowed smoothly (I have never done this before.
Just needing to finalise the lvt -is between Livyn Balance and J2 Natural Timber at this point. Any last minute pros and cons on either?
Really appreciate the pointers that have got me to this point.

 

Flooring arrives in the next day or so - went with Livyn Balance. I plan to prime the SLC with PE 360 so is a 1-1 mix too strong? Would it be better 4-1 water/primer? Still appreciate any input from the forum as I go. Thanks.

 

You’ve picked a good LVT

Well... just following up on the initial post to say a big thank you to all your input. I managed to self level the whole downstairs in 4 hours with the help of my son (on the mixer) and it turned out really well. The Murexin SLC that Adam pointed me to was easy to work with and dried to a smooth, non dusty finish. There was one patch that needed some feather finish to reduce a slope that was present even after the leveller was in place, and I was prepared for that. The feather finish just reduced the angle a tad and you wouldn't know the slope was there now the floor is installed.
I then used Murexin adhesive too and worked through the whole downstairs using the longest run in the house as a starting point. This was probably the most technical part for me, to ensure that I had the right tile widths at wall boundaries across the downstairs i had to compromise with thin strips in a couple of places though. I had hoped for the QS Livyn to arrive a week earlier than it did, and had taken annual leave to that effect, so I ended up having half the planned time to install it all but I worked loooong days on my knees (how do you guys do this for a living!!) and, working room by room, finished it in 6 days. The first room was a learning curve and I was a messy worker getting glue on hands, shoes, knees etc and getting it on lots of tile surfaces (thank heavens for builders wipes) and I worked hard to butt joints up as tightly as I could whilst the UFH was off during the install. I worked tidier from then on. I dry fitted each room and then glued down in 3-5 row sections at first - this was ambitious so I eventually settled into a 3-4 row pattern. The hallway was the hardest due to all the openings off of it and I thought I was never going to finish. I hand rolled as I went and then used a hernia inducing roller in both directions approx 30-60 minutes later.
The UFH was recommissioned slowly after 48 hours and I was paranoid that tiles were all going to lift off the floor but, over a month later, the only thing I have noticed is that a couple of the v-grooves have needed dried glue scraping out of them and there are a couple of boundary tiles that have a hollow tap right near the new skirting boards, even though I thought I had good coverage on those boards. If it gets worse I ma do something about it, but if a load start lifting I am going to sell one of my kids and pay to get it done!
I have an acute appreciation of your skills as professionals and NEVER want to lay a floor again. Massive thanks are warranted. If I new how to post photos I would, but I am scared that you'll see things that I can't
All the best!

 

Well done mate

 

Now you can see why we have minimum charges, those smaller areas are always the time consumers. Well done on your choice of materials and would like to see some photos of your work, sadly not all of us escape with our knees intact mine went about 10 years ago now I’m stuck in the shop explaining what kind of work’s involved and why it costs what it does, it gets frustrating selling 4 pieces of the same vinyl to someone who didn’t want to pay for install they want to do it themselves to save some cash sadly they end up spending more to fix mistakes than it would have cost originally.

dazlight - hope this attempt at uploading pics works. Go easy on me - it was my first go I have hit two humdingers of errors; firstly the only place where I managed to get two tiles with the same pattern any where near each other is in the centre of the living room and they are next to each other! Secondly, and inadvertantly I started to create a staggered pattern in the living room which I then reversed mid room to keep it looking ok. Unfortunately, I didn't notice that one or two of the first glued down rows in that room were in a randomised pattern that I didn't carry forward into the rest of the room. it really annoys my OCD when I look at it now. No-one else has commented on it yet though
