CA Pool Finishes recommends that you follow a specific procedure when starting up your newly remodeled or plastered swimming pool. The pool finish will immediately start to hydrate and cure after mixing and is most susceptible to staining, scaling, and discoloration during this time period. Proper start up procedures are critical and include the timely brushing of the pool surface. It is mandatory that the water chemistry is constantly monitored and adjusted for the best results. The start up procedures must be performed by the pool owner or a trained technician during the service life of any pool or spa surface.
