Last Wednesday a plasterer converted my textured bathroom ceiling to a smooth one.

It's been 4 days now.

I want to prime and paint it.

How long should I wait to be sure the ceiling is ready for painting?

Also, is any sanding recommended before painting? Has anyone ever heard of sanding after priming?

Below are before and after photos.

It's ready. Go for it. Unless it's REAL plaster, then you usually have to wait for 30 days.

Hi Gymschu,

The plasterer used Easy Sand 90 Joint Compound and Uni-Kal Veneer Plaster.

Hi Gymschu,

I checked the PDF of National Gypsum company and there's no mention of the "wait period" for painting the plaster. Any bags left lying around with instructions, striped bass?

No bags around, unfortunately.

The plasterer said three days were all I needed. But I just wanted to make sure because I recently had a bubbling issue with my kitchen ceiling.

It's alright, Gymschu. Tomorrow I'll got to Home Depot and read the instructions.

Thanks, anyway.

Please post your findings, I'm curious about the venetian plaster. Since it's a pretty thin coat my guess would be the 3 days.

My question is why on earth was plaster used to begin with to convert a popcorn ceiling to smooth?

Jeff, I'm not sure if this is true or not, but, I think if it's done correctly, you don't have to sand the plaster to make it smooth. Of course, a good drywaller can make it so joint compound doesn't have to be sanded either.

Well, if so that would have the advantage that you don't have to make a return trip after drying to sand. I'm normally the one doing the painting so I'd be returning anyway. I guess the other advantage would be no dust.

Personally, I can get drywall pretty smooth, but I've never been able to do it to my satisfaction without some final sanding. The edge of the seam where it transitions to the bare drywall always seem to have a micro ridge there. Maybe if I watered down my compound more I could eliminate that.

I guess I was thinking of something else I thought venetian plaster was a texture not smooth.
