Hi, i have a swimming pool without water, i want to paint it before i fill it but i have some important questions;

What kind of paint should i use?

Firstly I think you need to determine the nature of the pool's surfaces (tile, plaster, marcite, cement, ...). You can choose a suitable paint and primer according to this. For info about who sells on the web try the following search swimming pool paint.

As for the pump, filter and plumbing, I am waiting for your picture and specific questions.
