Hello,
We are having a glued vinyl floor installed in our new build (except for the bathroom). The flooring installers came but left immediately because the humidity was supposedly at 96%!!!
The painter finished his work a week earlier (Thursday), and on Saturday we taped the windows on the outside for the plaster. The flooring installers were there the following Thursday. On the previous Sunday, we heated for about 8 hours because the flooring company’s field representative advised us to do so. That didn’t seem to help much. The screed was already quite dry, with a value of 0.9 (I’m not sure about the unit).
Is it possible for the humidity to be that high after painting? There was no condensation visible on the windows. Unfortunately, we only aired the rooms a little through small window openings. After the installers left on Thursday, I cut large holes and ventilated twice a day. On the following Monday, I measured 40%. Is that possible? I’m at a loss.
Best regards

96% humidity is like being in a cave with dripping water, and with the current high temperatures, that means there is a lot of moisture in the air. Your description of when what happened is a bit unclear, but that doesn’t really matter. If the tiler says that with the proper official measurement the residual moisture is below 1%, vinyl flooring can be installed. It’s not clear why the humidity was so high that day (96% is obviously very high), and ideally that shouldn’t happen anymore. If the rooms now feel dry and not damp to the touch, there really shouldn’t be any problem with installation.
The result: either they actually measured a high residual moisture level, which could be possible, or they had two construction sites but only one team and had to postpone one site somehow. Just let the installers handle it. Next time, bring a moisture meter yourself or ask to see their measurement results. They are responsible for the installation. If the floor is too wet, the whole thing will warp badly and become a complete loss.

As far as I know, vinyl flooring should not be installed at high humidity levels because it will already be at its maximum expansion and gaps will form when the air becomes dry. At least, that was what was stated on the packaging of the vinyl I once installed. The limit was 65%.
Thanks first of all for your answers.
I understand that the moisture levels need to be right. I definitely want that to be the case and avoid any annoying follow-up issues.
But the 96% just seemed a bit high to me. Of course, after the painter has been, there is moisture in the house and it smells a bit. You can then assume the moisture level is somewhat higher. The second construction site could of course also be a factor. But that probably can’t be proven.
They are supposedly coming back tomorrow. Humidity at 40%.

If the painter just finished, a high humidity level is quite normal because you are not allowed to ventilate immediately after installing the wallpaper. If you now have 40%, everything is fine and the flooring can be installed. The later the flooring is installed, the less it will be affected during construction (for example, always after the wallpaper and paint).
