Paint coming off of walls when washed?

I'm repainting my room and was washing the walls down with just warm water and the 2 year old paint started to come off the walls. Will this be ok to paint right over? (its a dark color over a light color) or do I need to put a coat of primer over it?Paint coming off of walls when washed?
No you should be OK, but that's why you need to wash it down first. You will need to put 2 coats of paint on, make sure you use a good brand of paint like Benjamin Moore you will have much better results and it will look great for years to come and won't wash off like the stuff you have now. The finish is also important, if your painting a bathroom you will want to clean the walls so you may want a semi-gloss, if it's a bedroom you may only want a flat or eggshell finish, it will hide the imperfections in the wall better.Paint coming off of walls when washed?
1)wash the walls down with TSP


2) prime with Kilz


3)paint
Ok, paint comes off your wall for several reasons 1. if you painted on top of a previous slick surface, i.e. semigloss paint, your new paint didn't have anything to grip to. 2. your walls weren't cleaned so your paint didn't stick to the wall it stuck to dust ect... 3. you painted a latex paint on top of an oil based paint ( oil on oil, oil on water, no water on oil, unlessed primed). So, take off what you can with the soap and water, if it's not all coming off, then chances are it won't come off more, then prime with a Shelac based primer, Zinser makes one, you can find at most Lowes or Home Depot, then any kind of paint you desire. The primer will seal the old paint, keeping it from coming off, and give your new paint something to grip too. Hope this helps!
Put a coat of primer over it your were right.
When you mean paint comming off the walls do you mean it's chipping or flaking off or do you mean it just rubbing off like if you take a towel and rub on any painted wall surface with cheap paint it will end up in your towel. It's normal. Just lightly whipe the walls. If your so concerend just prime.
