Your pool project is almost complete. Application takes half to one day, depending on the size of the pool. Do not worry if the color that they are applying doe s not look like the sample you chose. What you are seeing is the grout that covers the pebbles and not the pebbles themselves. After applying the finish, it requires 24 hours to cure before we come back and perform an acid wash. Once we complete the acid wash, we will start to fill the pool up with water.
