Kitchen floor tiling prep help

[TigerUK]

Hi

I am doing tiling in my kitchen, I have removed top layer of adhesive lino tiles using a hot iron, it's hard graft and taking a while, I'm doing 3 hours a day after work and will take me 3 days to complete.

There is some horrible black lino tiles below, which I'm not taking off, there was was survey done by the council contractors on the kitchen floor and they discovered asbestos on the ground and thus, didn't remove the black lino tiles and put the beige tile on top.

You can see some parts of the black lino has started to come off, I will remove any loose bit by hand and minimise disturbing the floor.

I have a few questions, I've never tiled before so would like some help and if there are any tips you can give me that would be hand.

I want to make the tiles as level to each other as possible, I've ordered tile levelling systems. Are they required? or just nice to haves? Can you get a nice flat finishing without them?

I've heated the lino tiles well before lifting them off, most of it has come off clean, but some of it has left glue residue behind, do I need to get the glue residue completely off? or will the tile adhesive adhere to the lino adhesive residue?

Where the black lino tile has come off in patches with the beige lino tile, should I level it with some floor cement or should I just leave it for the tile adhesive and bring it up to level with the tiling trowel.

I plan on giving the surface a final clean up with a floor scraper and maybe apply some adhesive remover, then tile on. Any tips to get the perfect finish would be appreciated.

I would think the best bet is to go over it with self levelling compound. I had a similar problem many tears ago and the guy who did it came in and put the SLC down and then tiled it a few days later. It was fine and no new tiles ever lifted or had a problem.

You do need a specific type of slc if there's anything bituminous in the adhesive used previously,(it looks like there might be).

This is one, not sure if there are others:-

Thanks for the feedback guys, I hadn't considered bitumen/asphalt. Want to avoid putting slc all over the black tiles, because I don't want to take up too much height in the kitchen.

I searched around and someone else seems to have come across the same issue as I have. https://************/threads/ ... ive.83397/

It's the tiles themselves that have asbestos fibres, I want to fill the potholes with a slurry mix that can bond to bitumenous surfaces

Sorry, looks like I can't post links to the other forum, here's a copy of the message

 Hi, not really sure which section to post this in so apologies if this should have gone somewhere else....I know it's a fairly commonly asked question but I need to level out a downstairs bathroom floor (concrete) and was looking for some advise/reassurance (as this is a DIY situation) that I could ultimately use self levelling compound to level & cover the old bitumen adhesive.....

Story so far....

Stripped back old flooring (Lino), which they revealed some old Marly tiles which I carefully removed (as I know they may contain Asbestos), double bagged and disposed of up the local tip. This has left some black, bitumen-like substance on the concrete floor (see pic) which I have tried to remove mechanically but it's a complete nightmare to remove. Really don't have the time/budget to grind out so was hoping I could do the following:

1. Tidy up floor as best as possible, remove any loose materials etc. 
2. Make SBR / Slurry mix and paint over floor area (ensuring fully covering Bitumen adhesive) - leave to dry
2. Pour over SLC (I have already bought Mapei Renovation Screed as it had been highly recommended to me) and leave to go off....

Any thoughts? Cheers

Sounds like your plan is spot on. You don't need the slc to make it ready to tile, the slurry will do that, unless of course the floor needs levelling
