Concrete VibratorsAfter pouring the fresh concrete into the countertop mold, you may need to use a vibrator to help consolidate and level the concrete and remove air bubbles that could leave unattractive holes or pits in the surface. Not all countertop mixes require vibration. It all depends on the stiffness of the mix you're using and the effects you want to achieve. Buying tips: "Makita makes a 12-volt cordless insertion-type vibrator that works well for small projects," says Rhodes. However, since this tool must be plunged into the wet concrete, it tends to disturb reinforcing materials and decorative insets. You can avoid this problem by using table-mounted external vibrators, choosing a size and power level appropriate for the size and weight of your casting table. Even the vibration from a simple jitterbug sander may be adequate, says Rhodes.
