Scratch coat still soft next day?

Don’t do much of it, and just helping out friend.

Scratch coated yesterday using 4-1 with feb plasterciser . Didn’t realize but the cement we’ve used had plasticiser in already. (Master grade cement)

Came to mind top coat and still relatively soft. Could scrape off with scraper.

Should I leave to cure few more days before top coating.

Has too much plasticiser caused this?

Yes oveplasticised.

Leave it a week. But pop back after coating and dampen - not really soak it.

Strength of mix depends on substrate .
