Decided on a small play pool for the kids. 75' perimeter with 5' maximum depth. Today they sprayed the gunite and IMMEDIATELY afterwards I got a brief, yet hard rain. I understand wetting the gunite will slow the cure process and likely make it stronger. However, what I have noticed that concerns me a little is this:
1. The smooth finish on the bottom is gone where they brushed the bottom. The rain was hard enough to expose small pea gravel from the gunite.
2. Some water has accumulated in the bottom of the pool.
None of the walls, steps or benches show any signs of collapsing. The edge of the pool where the coping will go is now rough from the large raindrops. Anything I should be concerned about?
