Swimming pools are maintained with a variety of mechanical devices and chemicals. To keep the water pH level steady for swimmers, different combinations of chemicals are used to treat the water. In conjunction, swimming pool water is regularly siphoned, filtered and recirculated into the pool. The sand filter catches fine grains of sand to keep the water clean. These filters are made of plastic or fibreglass and can become cracked.

Turn off the sand filter and unplug the unit while making repairs to the device.
Put on rubber gloves and apply acetone to the cracked area with a scrub sponge to get any grime and dirt off the surface. Allow the acetone to evaporate for about five to 10 minutes.
Spread urethane epoxy resin over the crack on the sand filter using a plastic putty knife. Use the blade of the knife to make the resin smooth and even, then let dry as long as directed by the manufacturer.
Sand the patch on your pool filter using 220-grit sandpaper once the urethane epoxy resin has completely dried. Wipe down with a tack cloth to finish.
Plastic Pool Sand Filter Repair
Turn off the pool filter and hold a piece of fibreglass mesh up to the crack to measure its size. Cut a piece of mesh with scissors to overlap the crack by 2 to 3 inches on each side.
Put rubber gloves on your hands and thoroughly clean the crack in the fibreglass pool filter using acetone and a scrub sponge. Let the acetone evaporate before continuing.
Combine fibreglass resin with epoxy hardener in a bucket, following the manufacturer's mixing ratio. Mix thoroughly with a plastic putty knife until it's well blended.
Hold the fibreglass mesh against the crack and spread the resin/hardener mixture over the mesh using the plastic putty knife. Apply another coat of the mixture before the first coat dries.
Abrade the fibreglass patch with 220-grit sandpaper to make smooth and flush, then wipe down with a tack cloth to finish the repair.
