How long after plastering a pool can you add chemicals?

You should wait at least 28 days after plastering a pool before adding chemicals. This will give the plaster time to cure and harden properly. Adding chemicals too soon can damage the plaster and cause it to fail prematurely.

Here is a timeline of the steps involved in plastering a pool and adding chemicals:

* Day 1: Plaster the pool.

* Day 2-27: Keep the pool filled with water and allow the plaster to cure.

* Day 28: Drain the pool and clean it thoroughly.

* Day 29: Add chemicals to the pool.

By following this timeline, you can ensure that the plaster in your pool cures properly and that the chemicals you add are safe for use.
