I used the EpoxAcast 690 and opaque dyes to repair the edge of a damaged marble table. With a little coaching from you the result is excellent. I have just completed the filling in four pours, 3 in colour and a clear top coat. Three reinforcing pins were inserted. I have not final sanded or polished it yet but the end result seems excellent. The only issue I had was having to buy a sensitive gram scale from Jaycar. The mould making and casting went perfectly on my first attempt. I thought it was pretty easy to work with.
