Resurface question

[patrickphimr]

I have a 20 x 40 free form gunite pool that was built in 1985. It was resurfaced in 1998 with Marcite. It is in need of another resurfacing job. The surface is rough, with a few small concrete areas showing through. Beside from the surface, the pool is in excellent shape. A couple of questions: is there any major advantage of Marcite or Diamondbrite over paint on type of finishes? Are all of the paint-on type of finishes a short term patch? Can I do a Marcite job myself? I am aware that this is a major undertaking.

Paints will not last very long and once you do that you have to keep painting it and can’t do plaster unless all the paint is removed.

I’ve read that some place offers a roll on plaster but forgot who makes it. No feedback on how long it lasts.

The plaster isn’t really a DIY job, though I wish it was cause I’m a big DIY’r.

I’ve also heard of people installing a vinyl liner over the concrete as another option.

If you have just a new areas that need it, they sell plaster patch that can be tinted and applied easily after the water is drained, but end result depends on how much you care about the aesthetics and color match.

Advantages of Marcite over paint is durability.
Paint on type of finishes do not last as long as plaster finishes, I don’t consider paint finishes as a patch.
Doing a Marcite job yourself would be a bad decision, it takes a lot of trained personnel and specialized equipment.
