Pool Painting

Plaster pools are commonly acid washed to address issues like yours. Acid washing works by dissolving the top layer of plaster, and exposing a 'new' top layer underneath.

BUT . . . acid washing does not evenly dissolve that top layer, and the resulting plaster is rougher and more susceptible to stains, than the original surface. Careful, skilled application can reduce the problem, but many contractors either aren't skilled, or can't be bothered since their customers don't know the difference.

AND . . . the effects of acid-washing a pool with COLORED plaster can be unpredictable. Personally, I don't have enough experience with colored plaster to know how to tell whether a colored plaster pool can be acid washed or not.

Colored plaster is imperfect at best. The nice marbled swirls you can see in a new application will amplify as the pool ages, making for an odd, blotchy look. I've seen walls bleach white while the floor is still dark. I think a lot of the premature and irregular fading has to do with not paying attention to chemical manufacturer warnings for colored pools.

Acid washing is a big gamble, and has some negative results as Ben mentioned. If you can determine that only the top layer is faded and reaching down a little will get your color back, look at "polishing" your plaster. It's a lot of work to do right. Really expensive if you have someone do it while the water is in the pool. Still kind of expensive with the pool drained. The right equipment isn't cheap, and it doesn't seem to be something that produces a lot of work.

I am very much against painting pools. It's cheaper up front, but not in the long run. To give you an idea, we paint roughly 10 pools a year compared to plastering 30-50 pools a year. I'll maybe have a problem with 1 or 2 plaster jobs, and that is rare. I can count on going back to at least a quarter of the paint jobs for something. And understand this, we are meticulous. 1, because if I'm going to do it, I'm going to do it right. 2, I know the more care I put into it up front, the less the chances are that I'll have to go back.

Ok, so i had a pool contractor come out and take a look at my pool. It appears that the pool has been acid washed before and it may have taken a few layers off. Pool guys said that he also DOES Not recomend for me to paint my pool. As stated here, if I do paint it, then I will have to repaint every 2-3 years no matter what. So painting the pool is out of the question. I will look for a way to repair the top step but for sure NO PAINT.

Bizzy:

My first plaster job lasted 14 years. The first part to go, was the top step.
I replastered with colored Pebble Sheen. The pool looks new at the end of my second year.
