ᐅ Drying Time for Interior Plaster (Gypsum)

Hello and good evening. Can I install the polystyrene foam boards with compression tape 5 days after the interior plastering, or am I at risk of mold forming on the wall?

Styrofoam boards on the wall?

Waiting 5 days? How about 50 instead? What exactly is the plan?

Compromise tape?

Hello

Styrofoam boards = thermal and impact sound insulation?
Compressed sealing tape = perimeter insulation strip?

I would definitely wait longer—until the plaster is no longer "dark gray" but has become "light gray." In other words, until it is well dried. We have now waited almost a month and used a dehumidifier to help dry the plaster.
