Experiences and tips for installing click vinyl on carpet adhesive

Hello everyone,

I will be installing click vinyl.

Previously, laminate was installed in the apartment over a carpet. The carpet can be easily pulled up and does not stick to the adhesive anymore. I have already tested it.

Now, the adhesive is quite firm. The height of the adhesive is very low, maybe 1-2mm. The click vinyl has integrated impact sound insulation and a thickness of 5.5mm. A vapor barrier will also be installed under the vinyl.

My question now is whether I absolutely have to remove the carpet adhesive or if I can install directly over it. I have attached a few pictures of the current situation.

If not, I have the following plan:

- Rent a large concrete/screed milling machine with suction.
- I don’t want to level because the apartment is fully furnished.
- I will putty over major unevenness and drill holes.

Of course, cost is a factor here.

-> Which tools can be recommended for this?

Thank you very much!

I would just give it a try. Lay the stuff on a few square meters. It doesn’t have to win any beauty prizes. And then see how it behaves ==> either it’s okay, then click it apart and lay it properly or level the floor

It will push through sooner or later.

Hello
I had exactly the same starting situation. I scraped off the adhesive residues as best as possible by hand with a scraper before laying the click vinyl (9mm, floating). I wanted to avoid unevenness caused by uneven removal. Then you have to work with leveling compound. In my opinion, the problem will not be that the adhesive residues show through, but that it will sound hollow when walked on if it is not flat in places.
I would take the trouble again and prepare the substrate as well as possible. Otherwise, it's annoying if you're not satisfied with the result.

You can safely forget that advice. Vinyl is soft, the subfloor will compress over time, you can’t "simulate" that by laying 2 m² for 2 days without loading it.

Do it right the first time, otherwise you’ll have to do it twice.
