Old glue coming through the cushion floor / vinyl floor

Some 30 odd years ago a strong adhesive was used to stick down vinyl flooring in our kitchen, this adhesive is still present and is now drawn up through any new cushion flooring or vinyl flooring we put down. The floor doesn't become tacky, but it does become ugly and stained as the old glue brings with it colour from the old marley tiles underneath that it was originally sprayed onto.

So I'm looking to seal the old marley tiles and the residue of old glue before I have new flooring fitted. Any advice on what to use? The best suggestion I have had so far was to just Hammerite the entire floor. Their must be something more appropriate?

Any suggestions welcome.
 
You could try a heat gun and something like a Linbide floor scraper.

Failing that try a number of solvents on it to see if any will lift it used in conjunction with a scraper? In order I'd probably try:

Acetone
White spirits
Methylated spirits
Turpentine substitute

and if the don't work I'd consider (with caution!):

Lighter fluid (petroleum)
Cellulose thinners (MEK)
Hammerite thinners (Xylene)

WARNING! Almost all of these are highly flamable and need to be used sparingly and with the windows open
 
Thanks for the info... if I'm honest, I don't really want to scrape it off. I'm fairly sure that it has penetrated the marley tile, so no matter how much I scrape, it will still have some residue in there which will ultimately find it's way back up and into the new flooring. I was wondering if there was something to seal it with, maybe something resin based, in a tin, that I could paint on (I'm reaching with that last bit, I have no idea if something resin based is appropriate).
 
Had a friend suggest a tough lacquer, the sort of thing you might find in a sports hall... wondering how it would dry where the more old and more recent (still tacky) adhesives have been?
 
If the adhesive is still tacky or soft it suggests that there may still be some kind of solvent in there so painting it over with something is potentially going to fail.
 
My thoughts exactly, hence I was wondering if it could be sealed with something? I'd be there for months if I where to try and clean the adhesive off.
 
Thanks Daz, that might be a little bit overkill for what I'm after though, or should I say, a bit of a serious job. I'm trying to do it without removing all the cabinets if possible. A quick fix if you like. Although I appreciate that might not be the best way to do it.

Ardex do a this which I might have a go with:

They also do, which might work:

Failing that I might have a go at this:

If the floor is absolutely no longer tacky, you can lay F-Ball Adhesives Isolator membrane over the tiles and loose-lay the new Sheet Vinyl over the top of that.

Hi, sorry to hijack the post. I have the very same, exact situation - kitchen, original old marley tiles underneath (prob 1970s) and staining coming through lino which has been laid over the top.

Have looked at the F-Ball Adhesive Isolator Membrane but it is very expensive - about £180 for 7 sqm. Is there an alternative cheaper product I could use?

Many thanks
 
Have you the height to lay a skin of 6mm ply over the old sub-floor? That plus a primer might be a viable solution as well
 
This has been on hold recently due to more pressing matters...

I originally put down a cheap waterproof membrane between the old marley tiles and the new flooring, but it didn't really work. I used a low ish tack adhesive (out of fear of messing it up and not being able to reposition it, and possibly making the original issue worse), but the membrane never really adhered as well as it could have done, as such, you can 'hear it' underneath the new flooring. This is one of the reasons I want to go with a liquid / resin coat solution, something I can brush or roller on and hopefully not mess up. Plus, a coating of something will hopefully cause less issues with the look and feel when walking on it.
 
Went with this stuff in the end:

Two thin coats with a roller, each drying in little over an hour, went down easy. I was probably a little heavy handed, a little too much on the roller for most peoples liking, and as such got a bit of patination, but as it's going under a carpet it wasn't an issue, and my priority was a good barrier between the old marley tiles and new cushion floor above all else.

Prior to putting down the liquid membrane, I also spent a full ten hours with a big bottle of 'sticky stuff remover', a paint scraper and blue roll, scraping off as much of the old imbedded adhesive as I could. A joyful experience if ever there was one.

Hopefully that should all be enough to stop any residue of the old adhesive in the marley tiles coming up and into the cushion flooring. If I remember, I'll post back in six months or so and let you know if it's working.

Just to be clear, that was basically a sheet of plastic / waterproof membrane from the likes of ScrewFix. I'm sure it would have been appropriate for something, but not what I was trying to achieve. The liquid paint on option appears to be a better choice at this point.
