Help! Didn’t mist coat on plaster.

[TheEnquirer]

Hi all,

I think I made a big mistake. My plasterer recommended using Zinnser on the skim coat when it was dry. In the past I always did a mist coat but because this was an external facing wall I thought it was a good idea and assumed he ment straight on. So I applied the zinnser to both external facing walls and the fireplace.

Will it be ok? Looks ok.
Should I sand it down back to plaster?
What’s the worst thing that will happen or what’s more then likely going to happen?

Any help would be great.

Thanks.

Zinnser is just a manufacturer. What product? What is your objective?

Update, I used the Zinsser cover stain
primer-sealer stain killer. It’s been on the wall over a week and I can’t see any issues yet.

I hear some use Bullseye 123 on plaster but your the first to use coverstain.
It's on now so carry on. Be fine.

Just spend 1 minute reading the application data sheets for paints as will save you the grief in future
