    Judging the status of plaster

    In the process of draining my water in order to get the CYA and CH to acceptable levels, I am comcerned about my plaster job, or the lack thereof. (See Will Chlorine Kill Black Alage thread in algae section for the whole tale)

    I have drained down enough to expose two feet of plaster (or what I call plaster because I think gunite is gray) But all of the exposed "plaster" is rough, like a pumice stone. Nothing smooth about it. I should think it should be almost smooth like vinyl.

    32,000 gallon IG plaster (redone in 2003)
    Filter: Triton II sand
    Pump: Pentair Challenger 1 HP
    Test Kit: Taylor 2006

    Re: Judging the status of plaster

    Can depend on many factors age, type of material, scaling how the plaster was cared for. You can try to post a picture while it is exposed and someone may be able to chime in but texture is hard to determine from a photo. I would call a plaster company to come take a look, I would think they would for free on the off chance they might get an acid wash or re-plaster job out of it.
