How to Refinish a Fiberglass Pool Sliding Board

Over time, your swimming pool’s fiberglass slide or sliding board may become faded and worn. Because sliding boards are lightweight, easy to move around and easy to install, they are the most popular choice for most homeowners, but after a period of time, they require maintenance like all other things around your home. Follow the simple steps below to refinish your own fiberglass sliding board

Tools and Materials

  • Stir Stick
  • Fiberglass Get Coat – Marine Paint
  • Painter’s Tape
  • Sandpaper
  • Sander
  • Methyl ethyl ketone peroxide – Hardener
  • Bucket
  • Dish Soap
  • Sponge
  • Soft Towel
  • Paint Brush
  • Putty Knife
  • Roller
  • Respirator – Mask

Step 1 - Preparing the Sliding Board

As you work, wear a respirator or mask to protect you from breathing in harmful residue, which is not good when breathed into your lungs.

To begin, loosen and remove any peeling or chipped paint from the surface of your sliding board using a putty knife. With all the loose chips removed from your sliding board, you then need to use a sander and 180 or 200 grit sandpaper, sand the entire surface of your sliding board, being sure you sand every nook and cranny. It is important that all areas be sanded, as the gel coat will not stick to the old un-scuffed gel coat. 

Once you have thoroughly sanded the sliding board, you need to fill your bucket with dish soap. Use a sponge to remove any dust or residue from sanding. If you have not emptied the swimming pool, it would probably be best to use a sander that vacuums as you sand to prevent the soiling of the water within your pool. When you have completed the task, you need to hand dry the sliding board with a soft towel. Now all you have to do is use masking or painter’s tape and tape off any metal parts that are connected to your sliding board. 

Step 2 - Adding the Fiberglass Gel Coat

This step is accomplished much easily if you use a bucket and stir stick to mix your compound thoroughly. When mixing your Methyl ethyl ketone peroxide, a hardener into your fiberglass get coat, it is important to measure correctly using the manufacturer’s directions listed down the side of the container. Once you have mixed the fiberglass gel coat, you need to use the felt roller and a paint brush combination to ensure that all surfaces, including the hard to reach ones, are covered in the fresh coat of gel. Usually it is best to start underneath the sliding board and then work your way to the top side of the sliding board. When you have coated the entire sliding board, you will need to let it sit to harden for a minimum of 6 hours.

Step 3 - Adding the Finishing Touches

Once you have let the sliding board harden, you will need to apply a second lighter coat of the gel to the board and allow it to harden for a minimum of 24 hours before using the sliding board and getting it covered in water.
