Do we have to hire a professional to sand blast our pool?

Hello Marquezsa; I would not attempt to do this, myself! You really need to know what you are doing when sandblasting.

Perhaps, you can get a handy man who has done it prior, and he wouldn't charge as much to do this??

If you have a local Ace Hardware, I would call them, and see if they know of someone, and what they suggest?

I hope that this is helpful, to you! Take Care!

hire a professional.

Pool refinishing is an art and skilled trade. I would spend the money and do it right the first time around. Get multiple bids. Fixing mixtakes will cost more in the long run.

To have it done properly, hire the professional. This is their work they know proper techniques. Some things you have to let the pros do.

Take no chances! Call a professional. Get recommendations and before you hire.
