How to stop paint from peeling, I JUST painted.?

Every room i paint in this house starts peeling very quickly, and will come off very easlily with small pressure appied to it.





The first room i painted was mine, i didn't wash the walls or anything, only started to peel in a few spots. Every time i paint a room it peels worse. The last one i cleaned all the walls thoroughly first just to make sure that wasn't the problem, it is the worst room yet. if you push anything against it slightly big pieces of paint will tear off.





I do at least 2 coats, except for one room which i was painting white onto white so i just painted one coat.





I want to paint another room(The first room i painted actually, its been several years now) and I want to prevent this from happening this time.How to stop paint from peeling, I JUST painted.?
YOU ARE A VERY LUCKY PERSON !





I just happened to work for several years with the best painter in manhatten and know exactly what is going on.





When you paint FIRST you have to rough up the old paint with sand paper, we called it breaking the shine, DIY books I have seen call it something else but same thing.





NEXT USE A GOOD QUALITY PRIMER !





That's what primer is for ! It binds the paint to the old paint ! You should never paint with out primer, it binds the paint and also creates a base so you don't need several gazzillion coats to cover the old color !





The paint wont stick to your old paint because it's too smooth, when a professional painter paints they give the old painted walls a quick sanding to rough up the paint, now the primer has something to adhere to ! Go to your local paint store and ask them what grade sand paper to use, I think we used to use what ever was available in our stuff that day but they may have a suggestion of what grade to use. You can purchase one of those sanders on a pole that painters use, they should have a cheep one, don't need anything fancy. That will make it easyer to get the walls without using a ladder. Just sand enough to break the shine.





Any good quality primer at the paint store should work fine but you can ask the local paint store if they have any suggestions. We used to use KILZ primer, it also is a stain blocker and works very well. But any good quality primer will do. Stay away from the cheep stuff.





So


1. Break the shine


2. use primer next


3. paint to your hearts content !





Hope this makes your day !

It would be helpful to know what you are painting over. Like perhaps high gloss paint. If so the high sheen must be sanded or treated to remove the high gloss. The first coat you apply is what you need to determine whether it is bonding to the paint underneath.
Certainly this is a prime (No pun intended) example of how important PREP is. AND as others suggest, knowing what the surface was/ paint sheen was, etc. would have dictated what to do.





Cleaning is a part of the job, but I've applied thousands of gallons of paint and not every wall gets TSP prep first. Also I disagree, (Often) with the use of Primer. BTW I worked the trades in NY as well. Certainly to paint over any level of gloss finish one should Probably scuff the surface, though that could relate to Hundreds of sq. ft. of paintable surface to prep. Once scuffed there is less need for the additional expense and effort of primers. Admittedly a decent primer is often a more ';rough'; finish than a finish coat, hence allowing better adhesion.





Most often what one finds in your situation is that a flat or satin is being painted over some level of gloss, or latex over oil, and will peel even in sheets, especially from any abrasion.





PREP equates not only to the physical effort one expends but understanding the substance and properties of the MIXES. It's similar to an old quote, ';measure twice/cut once.';

Everything said by these folks before is right on the money. I've been at this crap all my life also, and the thing that I've found that works extremely well during the cleaning stage is instead of TSP, which I've used on just about everything from cleaning and prepping walls before painting, to dissolving heavy grease off of commercial kitchen equipment, and stripping years of grease and rubber skid marks off of VCT floors prior to resealing and waxing, using instead the non-phosphate Jasco liguid no-rinse TSP which works just as well as standard TSP but doesn't leave a powder residue that sometimes has to be rinsed and re-rinsed many times just to remove it. Like everyone says here. It's all about prep. So many disillusioned people out there think they are pulling something over on a customer or even themselves, painting over uncleaned, unprepped walls , just to save a little time but what kind of time are you really saving when you have to come back and not only repaint and clean but have a whole new step to do or you'll be back even another time, and that is peeling off All of the paint you applied before. And all it means if you paint more coats over the problem area thinking that it will fix it is that the paint will just peel off in a thicker layer when it does, and it will, and that much more time and materials wasted. Now that's really worth skipping a couple hours of prep for, isn't it ?
you probably painted latex over oil base paint We bought a house like that I had to take a wide blade scraper and remove the paint and start from scratch
Paint can peel if you painted Latex over Oil based paint without a good primer. Also if there was any moisture in the wall before you applied the paint.
always use a good quality primer, very little cleaning is usually needed but primer is absolutely needed. Find a Benjamin Moore paint store, all the pros tell me that is where they shop.





ask them to set you up with right combination of paint and primer... you may have to pay $10 more a gallon but your time is worth it.
