Painting over green sheetrock

mysterd429

Hi all. My wife and I recently had new drywall put up--mildew-resistant, green drywall--and we put a coat of Benjamin Moore primer and several coats of ceiling paint. The paint was Waterborne; I can't remember what the primer was. The primer covered most of the green, but not all of it. We'd put several coats of ceiling paint, and it looked fine until we dimmed the lights, and under the dimmed light, we noticed lots of spots where the green was showing through. We'd put more paint on the ceiling than on the walls, where there is no trace of green, though the wall paint is tinted.

It's been a few months at this point. What can we do to finally get good coverage? Thanks!

One more coat of paint should do it.

Joe's right. And, let me add it probably was poor technique. Working a ceiling is no easy task. Load that roller up with paint! It should ALMOST be dripping with paint. You have to move quickly to keep a wet edge on ceilings. Take small chunks at a time........a 2 x 3 ft. section is pretty good to start with. Let the roller do the work. Don't push or force the roller. Reload often. Don't skimp on the paint.......

Sorry Joe but after several coats of paint I don' t feel 1 more is the answer since you have used a quality primer and paint I would go back to Ben Moore for answers. You paid top price for quality products tell them your problems and let them answer your questions. That's the difference between a paint store and a big box store.

Thanks for your replies, folks. Obviously, I like ToolSeeker's answer better though painting a ceiling was new to us, and the chunks we did were about 3x6 at a time, rather than 2x3. I will give BM a call Saturday and see what they say. The space is complete except for this issue, so getting another coat up will be less straightforward than it was before. Any advice for covering things up when painting a ceiling in an otherwise-finished space?

Ceilings are not an easy thing to paint, usually it is white over white so it is very easy to miss spots. I personally always do 2 coats on a ceiling 1 coat 1 direction 2nd coat opposite direction. That way you have a pretty good shot at good coverage.

Thanks for your replies, everyone. I called BM on Saturday, and they arranged with the local store to have a can of paint waiting for me. Both fortunately and unfortunately, the bad paint job is only annoying and therefore isn't a high priority compared to other projects, but at least I have the paint for when I get to it in the list.

There are two beams that divide the ceiling basically into three strips each between three and four feet wide the length of the room, so I can do one strip at a time, so I can do one strip at a time. Any advice for covering the walls and floor this job?

Why would you cover the walls? You spraying?

Anyway, plastic sheeting for walls and drop cloth for floors

I'm not a pro and have been known to splatter paint from time to time using a roller. Thanks for the advice!

That is EXACTLY what I've learned over the years. Ceilings are a pain in the butt! It's hard to get an angle to see well, plus it's hard to get good coverage on them.

Loading the roller with paint is THE best thing I've found to do on ceilings- which is kind of anti-intuitive for me.

Throw down the drop cloth & go to it.

If you are using BM paint it should not splatter

If your getting splatter from your roller try slowing down, especially if you are really loading your roller.

I live for paint spatter! lol
Chris- a bit rosy to say BM won't drip..
If you are painting, plan accordingly.
Cover below, wear a hat.
Spatter happens!
