No, I do not glue down click systems. I used Bostik Best and thats all. I just had a feeling and the slab was full of spiderweb cracks in the surface so I figured the readings were artificially high due to the cracks.I was patching and you could virtually see the water get sucked out of the patch.

And it just looked dry.....OOOOOOOOH lol
