### ⭐⭐ Bubbles up in High Temps
*by S***T on October 30, 2016*

I have been using Solar Seal 900 since 2011. It sticks to anything, is paintable, and strong as glue. I use it on my roof to seal exposed nails, and in butt joints between cedar trim and cement board siding. It would be a perfect caulk except for one glaring flaw - after a year, it bubbles up at the butt joints. They look like someone is blowing bubble gum. So, each year, I get up on a ladder, cut into the bubbles with an Exacto knife, and stuff the inside with more solar seal. I've left a few go for a couple of years, and they got larger and thinner. I called a Solar Seal representative and asked for an explanation. The representative didn't know why it was happening. The bubbles are worse in direct sun, and virtually nonexistent in the shade. The first time it happened, I removed all of the caulk in the bubbled up joints and replaced it with new caulk. The next year, though, the same joints bubbled up. I'm not sure what causes this, but it's a major drawback for an otherwise perfect caulk. Update 10/8/2017: The past two summers have been mild in Indiana and the caulk hasn't bubbled up as much except in areas that get the most exposure. In these areas, the caulk cracked in some places and I ended up cutting it out entirely and replacing it. So, it's clear that the bubbling is related to temperature and expansion. My conversations with the Solar Seal reps confirmed that my situation was well within the caulk's advertised capability.
