Plaster second coat the next day?

Or worse, catalyse your second coat to set too quickly, just when you need it to stay workable the longest.

Mind you a lot don't get on with Multi for going off too quick anyway iirc...

Good luck with all that.

Today I'm using orange packets of thistle multifinish over plasterboards. Most videos show a skim coat a few hours after the first, but why not tomorrow? I'd have to smooth off any up bits with a float beforehand, (as they'd become rocks spoiling the finish), but are there any other reasons?

Should i wet the first coat with a paintbrush of water first?

I'm no plasterer, but I thought it would go off too much for the final coat to bond well if left e.g overnight?

catalyse? so maybe better to wait a few days until the first coat is dry before doing a second coat?

Anyhow it's not raining tomorrow so I'll be slating the roof not plastering
