I had some left over material from my counter top slabs and asked the fabricator to cut the top and side (waterfall) for a little cabinet. It was in my house for quite a while and edge got chipped a little. I finally finished the cabinet and the stick or top and side is unfinished. What material do I use to close the edge, already tried colicone but it’s soft and I can’t not find dark color (maybe should go with black) , but even if I do find a color the cilicone is soft and will probably be rubbing off with time. Please suggest what can I use? What do fabricators use for the edges? Attached is the picture of unfinished edge that I tried to close with brown silicone snd another picture of my kitchen countertop edge which is perfectly finished. How do I do that?
