    Repairing Gunnite Pool in Sacramento

    A twenty year plus pool in Sacramento with the plaster coming off.

    So I drained it and am looking at my options.

    1) Sand blast of the plaster, apply a bonding agent and re plaster.

    2) Jack hammer down to the original gunnite then plaster ontop of it.

    Obviously #1 is cheaper but does #2 have any real benefit?

    Some people talk of a silicon additive to the plaster, comments?

    Finally, any recommendations of contractors to use or avoid in our area?

    The chip-out is almost always the way to go. Since the plaster is coming apart, it will probably keep on flaking if you just slap new plaster on top of it. I'm not sure I've ever heard of silicon(e) being added to plaster, but the pebble finishes are much longer lasting than standard plaster.

    Option 3 is to fill it back up and just have ugly plaster for a while, if doing a full chip-out and replastering is not in your budget right now. It won't hurt anything being ugly for a while.
