Color and protection from wear and water intrusion are provided by a layer of gel coat on the surface. Gel coat bonds with the fiberglass resin and forms a tough shell that is resistant to the effects of wear and is superior to any type of household or marine paint. The gel-coat surface also makes the slide slippery, which promotes the function of the slide.

Things You Will Need

  • Masking or painter's tape
  • Pre-tinted gel coat
  • Acetone
  • Clean plastic container
  • MEK catalyst
  • Paint stir sticks
  • 600 grit wet/dry sandpaper
  • Surfacing agent
  • Polishing compound (optional)
  • Electric buffer (optional)
  1. Mask off all metal fittings or other parts of the slide that are not to be painted. Use low-tack painters tape or masking tape and ensure that the edges are secure to prevent wet gel coat from bleeding under the tape.

  2. Thin 1/2 gallon of pre-tinted gel coat with acetone in a clean plastic container to help it flow and leave a smooth finish. Add the methyl ethyl ketone (MEK) catalyst and mix well with a clean paint stir stick according to the manufacturer's instructions, or at 2 to 4 fluid ounces per gallon, as a rule of thumb.

  3. Roll or brush the catalyzed gel coat onto the areas of the slide that are to be painted. Apply the gel coat in a thin, even coat and avoid causing runs or sags that will add labor to the sanding process. Mix more gel coat as needed and coat the entire surface of the slide.

  4. Allow the gel coat to harden. Sand out any heavy brush marks or roller stipple with 600 grit wet/dry sandpaper and water.

  5. Allow the water to evaporate and repeat Steps 3 and 4 until the desired coverage and thickness are achieved. Add surfacing agent to the last coat, according to the manufacturer's instructions, to cause the gel coat to harden tack free.

  6. Allow the gel coat to harden. Carefully remove the masking tape. Clean all tools with acetone. Polish the slide with polishing compound and an electric buffer, if a high-gloss finish is desired.

The Drip Cap

  • Fiberglass pool slides share similar construction methods with other fiberglass objects, such as boats.
  • Mask off all metal fittings or other parts of the slide that are not to be painted.
  • Apply the gel coat in a thin, even coat and avoid causing runs or sags that will add labor to the sanding process.
  • Allow the gel coat to harden.
  • Clean all tools with acetone.
