    Casting Concrete With Recycled Plastic Aggregate : 5

    I used my big angle grinder with a heavy grit concrete grinding disc to smooth out the top of the casting. This began to expose the plastic. When the surface was smooth, I switched to a rubber backer disc and sandpaper. I started with 120 grit, went to 150 and finished with 240 grit. This gave a smooth, semi-reflective surface. If I was doing a serious finish, I would continue up to 1200 grit
