Paint on wood trim molding is peeling. need to repaint... how?

Our home was built 10 years ago (we moved in 9 months ago). The previous homeowner repainted everything head to toe before selling their home and for the most part they did an above average job. The exception is the moldings around the interior doors. The paint is bubbling and peeling off to expose bare wood (actually I think it's probably MDF). And if you look closely you can tell that they painted right over peeling areas themselves without sanding first so this must have been an ongoing problem.





What do I need to do to redo the surface and repaint so that this will not occur again? I'm thinking that I will sand to bare wood/ MDF, prime, and then paint with semi-gloss latex. Seems straightforward enough but since I don't know what caused the bubbling/ peeling I'm afraid it will just happen again.





Any tips for me???Paint on wood trim molding is peeling. need to repaint... how?
Take your time and scrape ALL the loose paint off trim. Sand and use a good primer.If its moisture, you would probably find some mold behind the loose paint. Also, latex over oil base paint will do this.(peel). p.s. A humidifier will add more moisture!Paint on wood trim molding is peeling. need to repaint... how?
Could have been a number of things. Not using primer initially, hummity, using an latex over an oil base paint.
I'm going to tell you the most cost effective remedy is going to be. You can't effectively sand latex/acrylic paint as it'll melt and gum like melting a rubber band and all the labor isn't worth it. Door casing is inexpensive and in cases like this I pull off the door casings and throw them away.





Cut the new casings to fit and if you're not an accomplished carpenter carfully pull the old ones and use them as templates for cutting the new ones.





Once you have them all sized to fit label them on the back sides as to where they go, i.e., which door and to what side they'll be applied. Now prime and paint them on a set of saw horses or bench. I strongly suggest you use oil based paints. For one you'll get a better appearing and more durable trim item, and two, this won't peel and blister later down the road.
