Hello house building community,
We have a small problem, we finished the insulation in our new building, then stapled the vapor barrier to the battens. Then we were told that it is better to attach the vapor barrier to the plaster instead of the masonry to achieve higher tightness. Therefore, we first waited until the plasterers were finished before we started sealing the vapor barrier. However, since we received a complete package for the drywall work, we had to install the drywall under the ceiling after the plasterers, as we have no standing space for the drywall and the underfloor heating was installed. Now we wanted to glue the vapor barrier to the plaster with Sigar Primur, which at first looked really good. But after 1-2 days, the Primur ran down the wall like water in one place or another. It simply didn't set. Since the plaster apparently is not completely dry yet, we think this could be the reason. Our problem now is that at the beginning of the year the screed will be laid and the foil is not yet airtight glued to the wall. Now we need a short-term solution. One idea would be to try to temporarily glue the foil more tightly to the wall with duct tape so that no moisture can get into the insulation, and then make another attempt with the Primur after the screed has dried.
What do you think of the idea, or does anyone perhaps have another idea what we can do?
