Refinish a fiberglass pool slide by sanding and washing away debris, then painting it with an epoxy paint. You will need a screwdriver or adjustable wrench, trisodium phosphate, gloves, goggles, epoxy putty, a putty knife, a pressure washer, 220-grit sandpaper, an orbital sander, a plastic drop cloth, two sawhorses and epoxy paint. Due to a long drying time, the entire process may take two to three days.
- Remove the slide from the pool
Loosen the hardware connecting the slide to the pool. Place the hardware in a secure location to use when reinstalling. Place the slide on top of two sawhorses in a well-ventilated area.
- Prepare the slide to receive paint
Sand peeling paint off the slide by using the orbital sander. For hard-to-reach areas, sand by hand. Clean debris off the slide by washing it with trisodium phosphate. Be sure to wear gloves and goggles to avoid skin and eye contact.
- Fill in cracks
Examine the slide for cracks or holes. Use a putty knife to fill in the cracks with fiberglass epoxy putty. Allow the putty to harden.
- Paint the slide
Apply a thin coat of epoxy paint to one side of the slide. Allow the paint to dry for 12 hours before flipping it over and painting the other side. Wait 12 more hours before applying a second coat.
