I put down a penny floor, I went to Kelly Moore paints they gave me some epoxy which had a chemical reaction to the pennies. I put down 22000 pennies so I tried a sample and it turns white. So I asked Garage experts will there be a chemical reaction to my pennies if they put down their epoxy he guaranteed me that it will come out perfect Garage experts got here on time. And very professional they answered all my questions, knew what they were talking about, I was very satisfied with their work. However, I did have a problem with the epoxy. There were bubbles all over my floor so I called up Garage experts they came out they fixed it and now it looks beautiful
