Is there a product that can cover gel coat areas of a fiberglass pool that are gone without draining the pool, such as adhesive sheets?
Thanks for the question Gary
The only product that I'm aware of is called Marine gel coat. This is for for boats and fiberglass pools and is specifically designed for under water applications.
You need to use the right kind of gelcoat because using the wrong kind can result in surface failure within a few weeks. You should be able to order gelcoat from the fiberglass swimming pool manufacturer.
My personal opinion is to allow the fiberglass pool repairs to the professionals. I've assisted with a few fiberglass inground pool repairs and can tell you it's no small feat. And I use the word "assisted", not finished by myself. I was there and saw what had to be done. Those guys were specialists in fiberglass swimming pool repair.
For more information, there's a guy that I've heard about that has done wonders with pools. I've heard of a guy that is in Florida. His name is Paul Pulver and his number is 727 - 798 - 1324.
He's a licensed Florida pool contractor and specializes in repairs and refinishing fiberglass pools. I know you're not in Florida but perhaps he can answer some more detailed questions.
Another good resource that I've used is fiberglass-pool-repair-com. Hopefully this will point you in the right direction.

My swimming pool (fiberglass) has developed dark blue streaks and patches. My husband thinks it may be a build up of calcium I have to get rid of it. Help any ideas on what it is and what will cure it?
Thanks for the question Joy
Before I get into the chemical side it would be good to have a complete list of your chemicals:
Chlorine, CYA (cyanuric acid/stabilizer), pH, Alkalinity, Calcium Hardness, and Metals (iron and copper).
It makes troubleshooting much easier and the process of clearing up your pool will go much faster. You can get this done at your local pool store. Without these numbers I'm just guessing at what the problem is.
Many fiberglass pool have multiple layers. 1 - 2 gel coats, an epoxy layer, a resin layer, etc...
Now, I had 3 fiberglass pools when I had my pool route in Arizona.
They all had the hairline cracks in them, but they never leaked and were very good with chemicals.
How old is the pool? It could be that the gel coats or epoxy layers are starting to show through. If this is the case you'll need to drain the pool and have it fixed by a certified pool tech.
It shouldn't be calcium because calcium hardness in fiberglass pools isn't as important as the calcium in plaster or gunite pools. Keep the hardness around 50ppm or so and you'll be fine.
If it is a chemical issue, I need the numbers.
Get back to me with the chemical numbers and I'm sure I can help.
Have a 16 X 30 Fiberglass, Inground Pool. Have developed a gray film on the inside walls, floor, steps.
Have tried Stain Remover, Metal out, everything my local Pool Store, has recommended.
Thanks for the question Mike
First, I'd like to have your complete chemicals readings: Chlorine, CYA (cyanuric acid/stabilizer), pH, Alkalinity, Calcium Hardness, Metals (iron and copper), Total Dissolved Solids. It makes troubleshooting much easier and the process of clearing up your pool will go much faster. You can get this done at your local pool store. Without these numbers I'm just guessing at what the problem is.
I'd advise you to get a Taylor FAS-DPD K-2006 pool test kit.
First, you need to determine whether the staining is either organic or mineral. Using a Trichlor tablet, hold it on the stain for about 10 minutes. Use a stick or a pool pole, not your finger. You can also use about 1/2 lb. of calcium hypochlorite (granular chlorine) in an old sock to put on a spot.
If the stain doesn't lighten up, gets darker or the color changes to black, it's probably a metal stain. To confirm it's a metal stain, get a Vitamin C tablet (crushed up ascorbic acid), put that in a sock, and place it on the stain. If the stain is removed, you can treat the pool with ascorbic acid.
If it's metals, you'll need a good metal sequestrant. A metal sequestrant does not remove metal from pool water. It holds it in solution until it can get filtered. Then you backwash the metal out. Because metal sequestrants break down over time and get filtered and backwashed out, you need to weekly dose your pool if you have high iron and copper. Metal sequestrants that are based on HEDP, phosphonic acid or something similar are the most effective.
Jack's Magic Blue, Purple, and Pink Pink Stuff, Metal Magic, Metal Free, & Metal Klear are very good.
Be sure any algaecides you use don't have any metals or copper in them. You don't want to add to the problem. A good one is a PolyQuat 60. Remember that algaecides are for preventative measures, not to kill already existing algae.
Hope this helps and let me know how it turns out for you.
