Plastering over 3 day old plaster

[pjo123]

yes I know, should have hired a pro

I've put a top coat on my landing walls, I did a pretty good job with most of it (for a diy-er)

But there was part of it that the wall was slightly uneven, so I (probably stupidly) evened it up with the top coat and decided I'd give it a second coat later.

Then I had to go out urgently and haven't got around to the 2nd coat.

It all seems to be drying well, a second coat and I think it will look fine.

As it's going to be Thursday I put the 2nd coat on and the 1st was done Monday, what do you recommend?

I worry that it might be too dry and suck the moisture out of the 2nd coat.

On the other hand, I worry it might not have finished drying and using PVA might trap moisture in there (or am I being silly)

Many thanks

I don't know the answer to your question but if I were in doubt I would wait for it to dry then PVA it and go again.

Maybe you can wet the wall and do it earlier, but I'd wait for a plasterer to confirm. Even then, for the sake of a few days is it worth the risk?

you are too late to add a 2nd coat, you are putting 2 first coats on

OK Thanks, in that case I'll leave it for a while before I give it another top coat
