Paint bubbles can form long after the paint on your walls and ceiling has dried. Take steps to avoid this problem before it occurs. Paint blisters or bubbles occur when the paint film lifts from the underlying surface. The loss of adhesion between the paint film and surface is usually caused by heat, moisture or a combination of both.
This condition eventually leads to peeling. It can be corrected, but the underlying cause of the problem must be addressed or it will recur.

You have worked hard to either pay for your home to be painted or you have done a fairly extensive DIY job.
You are pleased with the outcome — your home looks great. Then it rains, and the next day, you notice that the paint work is bubbling in some spots. This is a huge disappointment, and will take a lot of hard work to fix. So, what has caused it, and what can you do about it?
Is there anything you or your contractor could have done to prevent it in the first place? You may have wondered why paint will dry when it has been spread on a wall, but does not dry out when left in its tin. Exterior paints are generally oil based with a solvent, and react with the air through a chemical reaction. So when they are in their tin, they are not exposed to oxygen, and therefore do not dry out.
This chemical reaction allows the small molecules of the oils to form larger ones that have a more solid form, creating a polymer as it is spread on the wall. As paint dries, the solvent starts to evaporate, leaving behind the pigment colour , and the oil or binder.
These last two will form as hard film as it reacts with the air. Certainly he is not trying to build a list of satisfied customers. From the looks of the board under the paint, you had bare wood exposed allowing moisture to penetrate.
The new paint has sealed the moisture in the wood and has bubbled up in the places where the moisture is trying to escape. The best remedy is to scrape and repaint the siding during a warm dry period so the moisture can come out of the wood and prevent future bubbles from appearing. My painters always allow several days after power-washing, and then check with a two prong moisture meter.
Paint blister occur for several reasons and as been mentioned several times moisture is one of the causes. If the siding had been not allowed to dry properly after power washing, for instance, and immediately covered with paint the moisture would form a blister as it evaporated. The solutions to all of these issues is to re-sand the dried paint until blisters are gone and wait for the wood to dry completely. Afterward prime and finish as usual.
BTW: the blisters, as you probably now know, won't be resolved by themselves and will need further attention in the way of preparation work to look acceptable. The blisters if when scrapped or popped show the original paint color then you painter did not prep right. If you pop that bubble and it goes all the way down to the wood you are having a falsity from the original primer finally not being able to hold. Houses that have lap siding and that are older.
At some point someone caulked all the laps sealing up the spot where moisture from a he inside of the house is suppose to escape. This is why most bubbles pop up on the sunny side of the home and normally around your kitchen or bathroom walls. If you notice the place where he was able to scrape because that paint was failing before the job started and he was able to get to bare wood you are probably not having my any issue. In my home town with the new EPA regulations about lead paint and not being able to sand.
