Garage floor disaster convinced me to test for moisture every time

I always thought if a slab felt dry, it was ready for flooring. A few weeks back, I did a vinyl install in a garage space without checking moisture. The next day, the planks started to bubble up at the edges. I went back and found wet spots under the flooring. Pulling it all up and waiting for dry weather set me back two days. Now I grab my moisture meter for every concrete job. That simple tool saves me from callbacks and extra work. One tough lesson fixed my old habit for good.

You said most slabs are fine if they look and feel dry, but that's exactly what I believed before my garage floor failed. The top can be totally dry to the touch while the bottom of the slab is soaked. That hidden moisture will find a way up and ruin the install. It only takes one bad job to waste more time and money than a moisture meter costs. For me, that extra step is just part of doing the job right now.

Moisture meters just add another step and cost to a simple job. Most slabs are fine if they look and feel dry, especially in a garage. That extra gear feels like overkill for a space that isn't even a living area.

Yeah the "look and feel dry" part is what gets people, @emma_jones21. I read a thing from a flooring guy who said concrete can feel bone dry on top but still be holding a ton of moisture underneath from the ground. He said that's how you get adhesive failures or coating bubbles months later, even in a garage.
