Gunite is applied through a pressured hose with a mix of cement, sand, and water. During this process, there will be overspray around the pool area. To limit exposure or damage to surrounding objects, you will see our crews erect tarps to protect your home. These tarps are designed to protect from the large pieces that are being applied, but you may notice a light film or residue around the area as well. This is nothing more than aerosolized product, but it is an overspray and can potentially dirty or damage patio furniture and other items around the home. If you have anything nearby that is a concern or don’t want damaged, it is always best to remove it from the area or cover it prior to our crews arriving.
