Water marks on paint/can I sponge in Bathroom

Just finished painting my bathroom with Behr Kitchen & Bath(latex) about three days ago. Now there are water drip marks on the surface of the paint above the shower. Is this the quality of the paint or is water under the paint.

I was under the impression that Behr had some new revolutionary technology in paint. Otherwise, I would have used Benjamin Moore.

I used a dehumidifier to help dry the paint. I run the dehumidifier when I take a shower.

There is no bathroom fan. I was going to buy a fan and accessories at a major rennovation store. They kept ignoring me when I wanted to ask questions so I put the fan back and walked out. Personally, dehumidifiers work better than bathroom fans and they don't exhaust warm air outside the house.

The house is 45 years old and has never had a fan.

I painted the walls and the ceiling dark blue. People think I am whacked. I like the color except for the shine. Can I sponge another color over the dark blue or would that leave the surface too rough? Would water colloct in the pockets in the wall? Would I need to use a bathroom paint?

Thanks for your assistance

First things first. What gave you the impression that Behr had revolutionary technology? I mean what led you to believe that?

If they advertised that they did,specific to this problem,I am sure you will get your money back,no questions asked.

As far as your other problem goes I would slap on a coat of water based polyurethane after I did another coat to get rid of the water marks. You may want to let it cure longer than you did this time,and always wipe it down.
You could try to add some water based poly to the paint[test it] it may help to toughen it up.

A dehumiifier will not work fast enough to stop water forming on the ceiling. The reasone is that the hot vapor rises to the top[ceiling]

Get a fan!!!!!!!!! And put it in or near the shower. The remote mount ones work with a hose and you can put a vent right in the shower. A good idea if it is painted no matter the brand.

Behr is good enough paint, you have a bad situation.

Was the paint good and dry before the shower was used? Another coat should fix the problem. There shouldn't be a problem with sponge painting over the paint. You should get an exhaust fan - maybe try a different store.

The dark blue will show up drip marks more than a lighter color, but I suspect the paint wasn't cured enough before being blasted by the humidity

Yes
No, but the glossier surfaces are more mold/mildew resistant
Not in the wall, no
If you don't want to put a fan in, I'd recommend using a bathroom paint if at all possible
The dehumidifier just isn't going to cut it for a bathroom and a regular flat paint will be more susceptible to mold/mildew

Paint drips will also happen if the paint is applied too thick. Behr Premium paint is excellect. I only use the 100% acrylic paint for bathrooms and kitchens especially. They are a higher quality and very durable.

Water stains are gone

As the room dried out the water stains disappeared. I will definitely have to get a bathroom fan. I will probably leave the fan till the spring when it is not raining or snowing. I am not looking forward to chopping a hole in the roof or soffit. I will do more research on fans before I buy one anyway.

As for Behr's revolutionary technology, they had a flyer at Home Depot that stated they had a new revolution in paint. The particles in the paint are suppose to be closer together. I can't find any reference to this technology on their website.

I am debating on sponging on or ragging off another color. Possibly a green or a lighter shade of blue. I'll use Benjamin Moore paint for that. I also have wall stickers that I have ordered. They are cartoon frogs that should complement the dark blue and hide imprefections and glare.

I guess that is another thumbs up for Behr This is happening a lot lately. Why would you switch paint. You know the Behr works. What if the BM doesn't. When you mix a glaze it is much more water resisitant than just paint. I would just tint the paint a little lighter or darker and sponge it. No need for the BM imo.----your option though.

be careful what color you use to sponge on top of dried dark blue or you will end up with a VERY busy look. if you are just wanting to add a little dimension & mottled/aged look to what you've already got, then only go with the same blue but one or two shades lighter or darker. that'll give you a very subtle look. and you'll have to water it down or add glaze to it. another option would be to work the 2 colors at the same time - both your original blue and the new lighter or darker color. working with 2 wet paints at the same time will allow you to blend them together to get a softer more subtle look.

and definitely get an exhaust fan installed or at least leave the door open & put in a little oscillating fan to blow the air around. if your mirror fogs up, you're not doing enough.

also, sponging won't leave much, if any, actual 3-D texture on the wall. it's paint. not plaster.
