Preparing A Concrete Floor For Tiling - Floor Has Bitumen Down

[Dougs Third Go]

Cheers Doug do you just brush the slurry on?

yep, give the floor a good clean first, ie vacuum cleaner ideally as a broom just tends to bring up more dust.

Started to remove some bitumen and found floor has a large dip around 18mm it is in a kitchen through to a hallway so a large area, for me anyway. Can you get self leveller for that sort of thickness or will i need to use something else.
Thanks Phil.

Just been reading a few old posts and that was has been recommended a few times. Could you please let me know how you would tackle this. The floor area consists of a hallway and a kitchen. There is a door at the hallway end and a door at the kitchen end. The hallway if fairly flat but when you get about half way into the kitchen the floor drops by about 18mm over around 6- 8 foot. Where would be the best place for me to start?

Find the lowest point and level it to meet the desired height elsewhere. A long level or laser will help

Thanks Geoff makes sense. Do you use a roller or just push with a trowel, seems to be mixed views.

I use a plasterers float or a large floor squeegee

Thanks again Geoff. I will be doing it next week can I just run it through with you. SBR floor do you have to let that completely dry till next day? 1 or 2 coats
Batten off door ways
Have around 4 buckets with correct amount of water to start with
Start at lowest point spread to outside and corners
Work my way back up to higher level and carry on.
Have I missed anything important out?

Make sure it is an SBR slurry, not just SBR, and one coat will suffice. The rest of your plans are fine 🙂

Yes was going to do the slurry, Doug has mentioned before. Will let you know how I get on. I am doing it for a landlord we are doing the whole house up we where going to put lino down but he wants tiles so he doesn't have to replace it all the time. I have told him that I have never done it before (levelling). So he is paying me to learn and mixing for me so I am not to stressed about it but obviously want to learn how to do it properly.
Thanks again for your knowledge.
Phil.
