Hello!
We have tilers on site who will be installing tiles in the hallway for us. The house is a single-story home from 1945 with a basement, wooden joists with chipboard flooring, and the hallway is on the entry level. There has been some kind of mat (linoleum/plastic?) glued to the chipboard, either from 1945 or 1978. We will (soon) have ftx as ventilation.
The plastic mat has been removed, but there are still adhesive residues left. The surface has been primed and a reinforcement mesh is prepared for the leveling compound, see pictures. With all the talk about sick buildings, emissions, and unhealthy adhesives, the question is whether the adhesive residues on the wooden joists pose any risk during leveling and if I should stop the process before the leveling compound is applied, or if it's perfectly fine given the circumstances?

Completely okay according to me and practically harmless. It feels like in just a few years, people have almost become paranoid about the environment, allergy risks, etc. Sometimes you can't even hang up your jacket at a customer's house before they snatch up the paint and filler cans, frantically reading the contents and bombarding you with comments that it's pure poison and so on. The funny thing is, much of what I buy is already eco-labeled. There are 6 painters in the family. The oldest is well over 80 and is still going strong; in the past, there were no regulations on what could be used in the products.
You're absolutely right. One should really take emissions seriously. It's no fun for those who are truly affected.H Hans G2 said:
Now, I don't see any major risk for you. Quite the opposite, actually. The surface is primed. Moisture is added for a short period, if the moisture even reaches the glue. You have an old glue, most likely contact adhesive, which tolerates moisture better than today's water-based glues.
Had it been a concrete slab, the glue should always be removed. It's only when moisture remains for an extended period that a chemical reaction with emissions as a result can occur. It's actually so tricky that if you glue a mat too early while the slab is drying, the emissions can continue to live their own life long after the slab dries. Then it becomes very difficult to find the reason why residents in the household feel a health impact. Additionally, people have different levels of sensitivity as well.
