I used it in my bathroom. Now, rather than buying ceiling paint, since this is pricey. Can I leave the ceiling with just two coats of this?

Asked by: Anbe
I wouldn't - its a very flat paint and will catch dust and moisture - probably won't grow mold, but will look dirty. I don't use ceiling paint anyway - I always get the very whitest (usually untinted) wall paint and it stands up better. Ceiling paint is just watered down regular paint with a tint that disappears as it dries, so you can see where you've painted. In a bathroom, especially, its small enough that I can remember where I painted...

1-gal. Mold Killing Primer (Case of 2) is rated 4.6 out of 5 by 48.
Rated 5 out of 5 by from Great For Dew & Moisture Ridden Areas; Can Be Used Outside We have one spot in the back yard that between the house's shadow and the garage's shadow it receives minimal sunlight throughout the day. As a result a small portion of the garage wall grows a mossy looking dew at the very bottom of the wall near the grass line. This has been an annual frustration for us and we have lived here over 40 years. It just happens. Well, not any more. Typically I would spray the area with bleach or use one of those home wall washer products. I used this paint instead. I went about cleaning the surface area like before, but this time, I did a few swipes of paint for coverage. And then painted the wall over it. I have yet to see anything come back. According to the description, "the Mold Killing Primer contains an EPA registered antimicrobial to prevent the growth of mold, mildew and other fungal organisms on the paint film." For me, it has worked a like a dew repellent. I am hopeful that it lasts the year, and for many more years to come. For my purpose it was probably overkill to get a gallon of paint for such a small area, but there are needs that I will be putting it to good use. We have an outdoor water heater shed that is attached to the house. I will be using this in the paneling that encloses the outhouse to prevent moisture, dew and anything else from getting into the wood and making it look unsightly. I think if you live in a humid area or like me in a coastal area with salt-water air or early morning moisture in the air, this is a good paint product to have on hand.

Rated 4 out of 5 by from paint I LIKE IT THAT IT DIDNT HAVE A STRONG ODOR TO IT, EASY TO CLEAN UP, WHY DO I HAVE TO WRITE A LONGER TEXT?

Rated 5 out of 5 by from Doesn't smell too bad! Having survived painting a bathroom with oil based Kilz to kill mildew, I didn't want to do it again! This was SO much easier! No overwhelming fumes, easy water clean-up (cleaned up so well that I was even able to re-use the roller!), and it went onto the walls easily. I was most interested in the mold killing aspect, and I presume it will continue to work - so far (1 month) no mildew has returned. But it also works very nicely as a primer (duh!). Nice and thick, covering even the ugly brown that was on the wall, so I could paint 1 coat of a pale yellow! It does have an odor - must be the mold killer - but it isn't too bad, and it dissipates by the next day (with the window open). NOTHING like Kilz oil base!

Rated 5 out of 5 by from Great Investment So Far Pulling down the wallpaper in the master bathroom revealed a nightmare mess. The walls were covered with mold/mildew. I read the reviews on this product and decided it was worth a chance. It's a small bathroom so 1 gallon was more than enough to put on two coats and still have some left over. It's been just a month but, so far, there's been no tell-tale return. Prior to this purchase and application, I'd have to scrub my ceiling down with bleach at least a month. Now, it's absolutely sparkling!

Rated 1 out of 5 by from I have to write a dissenting opinion. This is latex, not absorbed by drywall, and for me it came off as I was painting!! Number one this product is overpriced. There is no way it is worth more than $20 a gallon. True, it did block the water stain and signs of mold, however as you can see it was not absorbed into the drywall. (Note: the primer had been on the ceiling for at least 2 weeks before I started painting.) I used regular ceiling paint with a little bit of added texture to cover any imperfections in the ceiling. Admittedly, it was a bit thicker and heavier than regular paint. As I was about to finish, I noticed a small air pocket where the paint and primer had come loose from the ceiling, as I went up on the ladder that small area got bigger and bigger until finally about 20 square feet had come loose from the ceiling, about the exact area that I used the Zinnser mold killing primer as opposed to my regular Behr primer. Horribly flawed product, and now I have to start over. What more can I say about it?

Rated 5 out of 5 by from Watching closely We were going to put new counter tops and sinks in both bathrooms. The master bath went smoothly. When it came to the second bathroom. we found a mold when we removed the old counter top from the cabinet. I than removed the cabinet and found mold in the sheet-rock and back and bottom of the cabinet. I removed the cabinet to be rebuilt (since HD guessed $500.00 for a custom built one). After everything was taken out I painted all the studs, drywall back ( other wall) and some of the sub-floor. I hope this stuff works, the new dry-wall I cover the studs will not let me see what is happening inside the wall. The new dry-wall will also be painted (both sides) with this primer. I hope I never see mold in that area again.

Rated 5 out of 5 by from Works as Planned The first thing to consider with any mold/mildew paint/primer coverage is to find the source/reason for the mold/mildew problem. Covering up the problem will help to get rid of the visual/viral aspects but the "reason" for it will still exist. As for application. We have a closet that is closed up almost constantly and it provides access to the crawl space under the house. This crawl space has a musty odor and tends to make for a musty closet that promotes the growth of mold/mildew. We are looking into a way to "vent" the closet but in the meantime, I have applied a liberal coat of this primer prior to the new paint. It covered the problem and masked the musky odor. Based on the mfg. claims and my use, I see no outbound signs that the mold is present BUT not dealing with the root cause may lead to it coming back. Product is easy to apply, water based making for easy clean-up and not an overly power smell. I'm happy with it!
