Lay down concrete forming panels around the rim of the pool shell to create a barrier around the pool. These forming panels create the shape of the inside edge of your concrete. Fasten these panels to the pool edge with screws.
Spread a layer of gravel around the working area and tamp down until it is even and tightly packed. On top of the gravel, lay down the metal grid work. This provides a solid base for the concrete and strengthens its bond when it cures.
Spread mixed concrete evenly around installation area until it forms a smooth and even layer across the work area. Ensure that the concrete does not spill past the forming panels.
Allow the concrete time to solidify. Different brands and mixtures of concrete solidify at varying rates. Consult the concrete manufacture for setting and drying times. Remove forming panels only when the concrete is sufficiently dry.
Wet the concrete frequently with a hose or lay damp burlap over the installation area. This saturates the concrete and strengthens its molecular bond.
