ᐅ Silicate Layer When Applying Plaster?

Hello!
Greetings to all readers, helpers, and those who keep online forums alive by participating.

I vaguely remember information from a mason that after plastering, during the drying process, a silicate layer forms, which needs to be removed before applying the next plaster coat so that the new layer can adhere properly.

I couldn’t find any information about this online and thought I would just ask the experts.
I appreciate any information.

Best regards, Goodwill

I have never heard of this with plaster; I only know this applies to anhydrite screed. Moreover, there are different types of plaster, such as lime, cement, and gypsum plaster. So, no need to worry.

In some areas, we also have plaster that is still quite damp and does not dry quickly. The site manager mentioned that a layer forms which prematurely seals the pores. As a result, the moisture cannot escape easily. It can be lightly sanded or abraded to improve drying.

Then I must have mixed something up. Screed, not plaster!
