ᐅ Primer for drywall

Hello,

I installed a suspended drywall ceiling in the basement (green gypsum board, the moisture-resistant type).

I have treated it with Murexin LF14 (diluted 1:1 with water) using a broad brush/primer brush in the first rooms. It felt like I applied more on the floor than on the ceiling 🙂. In the other rooms, I also applied Murexin LF14 (but diluted 1:2 with water) using a roller.

My question is, how many times should the drywall be treated with this, and how much coverage is needed? Is it enough if the boards appear shiny under a spotlight after application?

Should a heavier application be applied in the area where a sauna will be installed?

Thanks for your help!

The primer is used to equalize the absorbency between the drywall and the filler and to act as a bonding agent. So if it looks shiny, that should be sufficient.

The sauna will surely be installed separately, so the absorbency of the drywall does not affect it.
