I live with my wife and daughter in the Bay Area. We got lucky and found a below market apartment, but we have to handle nearly all of the maintenance ourselves because our landlords live in Taiwan. We notices some new bubbling/cracking on our porch now that the rainy season has ended, and I’d like to repair it before it becomes a huge problem. I used to repair rubber roofs and tar roofs in college, so I know how easy it for a DIY job to mess this up.A little background...the deck was cracking and flaking when we moved in. Since our kid likes to play out there, I swept up all the sealant dust and chips, and hoses down the porch. It gets really hot to the touch during the summer, so I bought artificial turf to cover the deck. It rained intermittently this winter, so we didn’t get to use the deck much recently. Today I went out there to pull the grass back to clean and I noticed two new bubbles. They’re gas bubbles, and I can tell they aren’t full of water. One’s cracked, and I can see it deck is covered by rubber painted with a grey colored sealant of some kind.I don’t know where the bubbles came from—they could either be from osmosis due to water pooling or hot air and vapor from below (our apartment can get hot when the people below us have their heat on, but I don’t know how airtight our building is). Regardless, I’d like to patch or reseal this somehow before it gets worse. I’d also like to resurface the deck since whatever’s on it now seems to be on its last leg.Can anyone offer advice on how I should proceed. Almost all of the research I’ve done on the issue points me towards patching unsurfaced rubber roofs, which I have done, but I don’t think’s applicable to this situation. Here’s the link to my imgur thread of pictures. via /r/DIY http://bit.ly/2HzREON
