I bought the 1x18 inch long brass anchors in the aluminum tubes to install in my floating travertine deck. However, when I core drilled a 1 inch hole into my scrap piece and then tried to install the long anchor, it fractured my scrap piece of travertine. Luckily, it was a scrap piece. I guess the hole needs to be 1-1/8” as to avoid putting stress on the travertine. So, if I use the 1-1/8” wet core drill, I will have about a 1/16” gap all around my anchor. What should I use to fill in the gap for a clean finish?
