Tile guys were using a hammer to find hollow places for filling and made stuns all over the place. I was planning todo a simple brushing with 60 grit tynex but now it looks like this will be a deep grind. The layout will allow me to hose off my slurry in most places. I usually use frankfurt stones but might want something more aggressive. I know it will eat up any braised, I need a super hard bond. Any suggestions?
