    Fresh gunite leaching milky white substance.

    Greetings,

    After a long wait, our builder finally poured gunite this week in North Texas. We have been watering multiple times a day in the heat. ( sometimes 6 -7 times.) In the mornings, one part of the pool ( where were having water before the pool went in ) in a corner near our steps will still be slightly damp, but is leaching some milky whitish substance. Any thing to be concerned about? We are doing mini pebbles, I assume that it won't leach through them?

    Thanks.

    Adding a picture from noon today. If I don't wash it away it will eventually flow down to the deep end of the pool.

    I've seen similar stuff on plain concrete, but I wasn't sure until I emailed onBalance, a member here. Here's his reply to me (I was hoping he'd respond directly...)
    ...go ahead and him that it is normal for gunite to leach white "stuff." Gunite is very porous and often does that. The white stuff is actually common calcium carbonate. It won't be a problem once they plaster the pool.

    Troublefree does not mean Maintenancefree. It's like brushing your teeth: You can spend a couple minutes a day and pennies a week or go to the dentist once a year and spend several thousand dollars.
    A pool is like a pet - you have to feed it every day, even the days you don't want to play with it!

    Awesome thanks! It has been quite the ordeal to get to this point due to water/wet soil. So this is very helpful.
