Crosshatch adhesion tests on tile

A quick video on adhesion to tiles and how to do a simple test to gauge if you can get a good bond.

PS. If you're wondering why I didn't grind the tile first, it's because the client actually liked the look/pattern of the tile and was hoping that could be preserved if possible. By simply going over the top with a clear coat, he could get the extra slip resistance he was looking for without ruining the look.
