I have a Fiberglass inground Pool/Swim Spa/Whirlpool built by Rio/Aqua Swim-N-Spa .
This is a combination pool, swim spa exercise pool , & whirlpool .
It is ten years old and sits in a 6" bed of sand that surrounds the entire bottom & sides of the unit for support.
The fiberglass shell unit is 5/16" thick mostly chopper gun fiberglass .
19'long X 8' wide X 5'deep with a pool tile waterline border & with a wall that seperates the 8'X 5' whirlpool area..
It is in a sunroom and is used year around.
The pool heater heats the sunroom .
It has a white gellcoat finish that is now getting thin in spots & discolored.
There are a few small stress cracks on the steps~~~not very bad cracks.
I can grind these out and re-glass with polyester resin , cloth/ mat & resin fillers.
My Questions to the fiberglass experts on this forum ~
I would like to re-gellcoat this entire pool/spa unit.
Do I need to remove ALL the old gellcoat in order to do this ?
OR~
Can I just clean, degrease & sand, and rough-up the old gellcoat to prep for new gellcoat application ?
Can I roll/brush , or spray on new gellcoat ?
How thick ?
Most gellcoat used on boats cures in the hull mold between the new uncured fiberglass without air~
Is there a type of gellcoat that cures directly in the air ?
Or ~~~Do I need some sort of spray on air barrier to use after the gellcoat to get a proper gellcoat cure ?
What sort of gellcoat can I apply that will hold-up during continued water immersion in a fiberglass pool/spa used year around ?
The current old gellcoat has no osmotic bubbles , or blisters.
Who sells this sort of gellcoat ?
It does not to need to be super glossy like a new boat.
In fact a slightly matte rough finish might be safer to use on the pool/spa.
I am not really married to any specific color~~~
It is white now~
I just want something that will hold-up in this unique poo/spa applcation that I can spray , or roll / brush on myself.
How any square feet typically does 5 gallons of typical gell coat cover ?
At what temp can it be applied ?
I wish to re-gell this fall~if at all possible ?
I know this surface needs to be super dry before application of any new gellcoat.
Any and all help greatly appreciated .
Thank's Guys .
