Hi,
I could use help in making sure I do this repair correctly. I need to remove the paint and fix the cracks in both fiberglass and concrete.
First I need to blast of the old paint. Pressure washer isn't fully cutting it even with a rotating nozzle, there are about five coats of paint including the original 1970 coat. It gets most but then I need to grind it and that's slow, really hard work and really messy on the rest of the yard. What's the best way to get to bare concrete? Soda blasting seems like it would have least impact on the garden that's nearby, but will that work?
I was about to rent a big soda blaster but thought I'd better ask the experts first! I need to blast down to the concrete on the bottom.
I also need to remove the paint from the fiberglass, and I think the only safe way to do that will be to grind it off - let me know if there's a better way (I tried the pressure washer and sheared a little layer of fiberglass off it so no more!).
Second there is a crack in the middle of the pool right at the top edge of the ramp - it basically follows where the shallow end/deep end flag normally would bisect the pool, going through both the fiberglass and concrete.
Concrete repair seems straightforward since it's hairline, I can clean it and install carbon-fiber staples. There's a lot online about this.
Fiberglass though is a mystery, it's a 1/8" wide line that's nearly straight up and down.
What kind of fiberglass do I use to do the repair - should I get a boat-hull repair kit? Is this different from a fiberglass car-repair kit?
Details:
Pool is rectangular about 35,000 gallons, with a deep end, a flat ramp up to the shallow end, and shallow end. Salt generator for chlorine, DE filter, gas heat. One skimmer, one drain, two returns (one can also run a Polaris). Concrete bottom, fiberglass sides (one sheet of fiberglass unrolled around the perimeter of the pool, about 3' tall).
I'll post pics tonight if it will help.
Thank you!
