Emulsion paint drying time?

330d

How long does emulsion take to fully dry and harden?

I have painted my room in Johnstones trade acrylic durable Matt paint over a week ago.

Today I applied some frog tape delicate and the paint is peeling off.

It should take 4 to 6 hours to be dry, maybe 24 to be fully hardened.  It sounds as though you have other adhesion issues that time isn't going to help

So why would there be adhesion problems?

It was freshly plastered wall which was done about 8 weeks ago.

I then painted 2 mist coats of Leyland trade emulsion paint.

And then finally 2 coats of the Johnstone's Trade Acrylic Durable Matt.

I don't know whether this is the cause of your problem but if you look at the Q&A section for Leyland Trade Emulsion on Screwfix they say not to use it as a mist/base coat for other paints. If you didn't dilute the Johnson's it might not have keyed properly.

The emulsion has come off because the plaster has not been sealed. I always use Zinsser bulleye 123 to seal walls & never had a problem. I would sand down the walls to get all the loose paint then seal it then repaint.

That sounds like a big job. Would it be easier to use lining paper?

We had this with one of our ceilings. Instead we stopped using tape and just got a decent cutting in brush.
I do feel your pain though. We've just had a wall plastered and having issues with paint peeling. I'm just trying zinsser no peel to see if that helps with stopping it.

But this is a freshly plastered wall.

Thanks. The Johnstone's paint I diluted around 15%
