I'm in the process of making an outdoor island/grill table. I need to come up with a counter top that won't cost an arm and a leg, but will withstand heavy rain, hail and strong winds. Would it be possible for me to make tiles out of quickcrete? Make wooden frames 6"x6"? Maybe seal the tiles when dry with some type of weather proof material to make them easy to hose off? Any other materials that might work? Thanks for any help you can give me!!
