Fast Set

I used Fast Set Extreme to glue down 2 five foot tall bronze elephants to a concrete base. The client had them moved. They had to break up the concrete and grind the concrete from the feet of the elephants. Pretty impressive!

“Bonstone Natural Stone Repair Kit worked great for the small crack I had in my granite. I wasn’t sure if I would be able to repair it myself but the instructions made it simple.”
