Thread: Repair seal coat in Gunite Pool

    Repair seal coat in Gunite Pool

    Need information on how to repair the damaged seal coat in our gunite pool. We have a saucer size section of the final seal coat (looks like egg shell thickness) that cracked & peeled off exposing the white plaster under it. We have easy access because it's on top of the first step into the pool, therefore we can lower the water easily to have a 'dry repair', if necessary. Any product & instructions would be appreciated....ggo 36

    This is interesting as the plaster itself is what seals the pool, no other sealer should be necessary. Do you know what the seal coat is made up of?
    16k gal plaster with raised spa, Jandy DEV60 filter, 2 HP 2-speed SHPF Jandy Stealth pump
    Hayward Aqua Rite T-15 SWCG, Jandy LXi 400k BTU NG heater, 350 sq.ft. of Sun Star solar panels, TF-100 Test Kit, Dolphin s300i Cleaner

    Yes, regular plaster was put over the 'gunite', & is still white & beautiful..... But the finish coat is very smooth & definintely not the same texture that is under the 'egg shell' material that has cracked & broken away. I am looking for something that will be applied with a putty knife & self leveling, because in my research there is always a mention of beveling or sanding out the area to fill which seems over correcting because the missing material/plaster is barlely 1/16 of an inch thick. Maybe just brushing the new plaster when it was first put under water is what made the difference. I'm not the expert here & we live in a rural area so finding a pool builder has been a little difficult....thanks....
