how long does it take to pour a driveway
Groovers can be either long-handled tools that can be used while standing or reaching for work, or hand tools that can be used to crouch for close-up work. Both are used to cut a groove in concrete. It will be easier to traverse a larger project using a longer-handled groover.
To prevent slippage in wet conditions, brush the concrete with a broom. Let concrete set for a few hours so that you don't get clumps from brushing. The temperature and humidity will determine how long you need to wait. If you notice clumping, smoothen the area with the magnesium float again and allow it to set for a bit longer.
