I am really impressed with Rustoleum Zinsser's Mold Killing Primer, I was thinking could this really be true, reviews seem to go both ways but I was willing to give it a try. Had been very hot and humid when it came in and then raining, so had to wait till had a nice day to apply and wall was dry, finally got my wish . Have wall between man door and overhead garage door that leaks when hit with heavy rain and drywall near wall gets wet and before I can get gutters installed to stop leaks, need to clear up mold or redo the drywall. But thanks to this great primer I can go ahead and finish paint, will wait a couple more weeks to make sure all is dry but seems to have cured the mold and I can get gutters installed now that is not 105 deg in the sun. Can only say thanks to Zinner

Last year after hurricane Irma the big concern was mold, as salt water storm surge had flooded the area. I would have liked to have used this product then, but now even though there is not any showing, I am going to apply the Zinsser mold killing primer to the affected areas and then apply a topcoat as a prevention. First I applied it using a 3" brush and even though it worked it is thin and I had to pay close attention to it dripping or running. The next day I applied it using a 6" roller on several different extensions. I used a 1/2" nap 6" cover and that worked best because it holds more paint than a 3/8 cover and it could be pressed into the corners and cover the areas without having to follow up with a brush and best of all fewer drips. I liked that it can be used as an exterior primer, no smell or fumes and easy water clean up.

Our friends and family raved about this product. We purchased the 5 gallon bucket after driving over an hour to the closest available store that had it in stock. When we got home and opened it, it was runny and thin like water. It didn't even coat the wall. Product was returned for a full refund. Disappointed.

Oh no, that is not was we like to hear Rena. Prior to use, be sure to thoroughly stir Zinsser Mold Killing Primer to ensure any settled pigment is re-distributed in the can. Proper stirring will ensure the Primer is the correct consistency. - Rust-Oleum Product Support 6
