summer paint job is peeling on garage....


i reside in ne/sd. two of us painted the garage and house this summer. as i looked out the window this morning (dec. 26th) i noticed an irregular white spot on one of the walls of the garage (about the size of a basketball). so, i bundled up and went out and took a look. the new paint was off---and noticed many "bubbling" spots on the side and is ready to come off. btw, i did need to put two coats on.

the garage used to be a cream color and i painted it with "coffee kiss" from Pittsburgh Paints Ultra.

i am just an amatuer painter and have only painted a few times in my life, but, wondering what the possibilities may be that caused this?

guess i know what i will be doing this spring!

Could be a thousand different things that caused this. Prep? Did you clean, scrape, sand, clean again before applying primer? Was there excess moisture in/on the surface when you painted? Did you use quality paint? Is the garage heated? Insulated? This could be a factor in the peeling of the exterior. Did you have a hail storm? Hail does horrific damage to ANY painted surface. Could the gutters on that side of the garage be plugged up allowing water to run over and onto the painted surface? Really could be any of those things or none of those things.

Wait until Spring, scrape, sand, then prime the area, let dry for a day, then wipethe area with a damp rag, then paint.

Latex will always bubble, whereas Oil will chip.

Is it failing at the bottom of the wall?
Got a picture, it just might make for better guesses. Do not need a close up!
We know what a bubble looks like.

Flybynyte, if you give us a few more details and take a pic as Joe suggested, we can give some more precise advice. Did you paint over a high-gloss surface? Like I said in my original post, it could be one of many possibilities.......we need YOUR help to nail it down. You surely don't want to go through all that hard work AGAIN and have it peel AGAIN?

Blisters are caused by moisture. Paint breathes and allows a degree of moisture to pass through. My bet is that this last coat of paint effectively sealed the garage and has proven to be a better vapor barrier than the previous coat(s). The previous coats are breathing and when the moisture hits this coat it stops, accumulates, and causes the blister. The humidity level in the garage is higher than that outside. I'll bet that the wall that is blistering is the wall that takes the brunt of the sun.
Or
I heard of a local guy who painted some siding in the late fall. The paint froze over night and in the bright warm sun of the following day began to fall off in sheets. But you painted in the summer.

A lot of good suggestions here, but a few key things are missing besides surface preperation, existing paint type and condition before painting, wood or metal substraight and condiotions during application. A pic and more detail would be helpful or you could just paint it again and see what happens this time.

Can you post a picture of the paint blister? 90% the issue is water moving through the coating causing failure. Scraping and re-priming over and over can be frustrating. Read the article below for some trouble shooting and good luck.

The blister is caused from the paint reacting with the Chaulking old paint that was never removed. Next time use TSP to clean the chaulking off
