Teak Decks & Grinding the caulking down
I have teak decks with were done 20 years ago with the black caulking. Now that the teak has weathered the black caulking if about 1/16 to 1/8 inch higher than the decks. I was told I could use an 8" grinder with a soft pad and 80 and 120 grit sandpaper to cut this down. I would think this would scratch the teak and leave swirl marks, but the guy who told me said it wont. Any thoughts on that?
