Pond liners are usually black because once filled with water it sort of disappears. Blue would look too much like a swimming pool, and either blue or white will be hard to hide when the water level drops. A black pond liner really doesn't look spooky with the water sparkling and fish swimming. Any liner quickly becomes covered with algae and sediment, but I really think the white would show through too much.

I imagine your installer can do the second coat in black without a problem. Or maybe mix some of the remaining white into a can of black so it doesn't seem too stark a contrast with your stone walls.

Now that I've made a case for black, I will admit that my rubber liner is charcoal gray. I used roofing rubber and it just turned out that way -- I got lucky. Any part of it that shows is less obtrusive than black would be.

So yeah, white and black epoxies mixed might work for you.

Good luck.

Thank you Sharon ~ That's a good idea - I wonder if we (he) can get a smaller can of black - grey would be good, I really wanted grey or tan. I hadn't thought of mixing a smaller can (it's so darn expensive) $100. gal. ~ Gack. If not, why couldn't it just be painted over maybe? I'm really disappointed, the white just too....white!

I don't blame you about the white. If you were to paint it, again you'd have to be concerned about toxicity. Also you'd need a paint that would stay on under water. It might be simpler to stick with the epoxy.

I'd go with black. Any other color looks pretty nasty once the coating of algae starts to grow on the pond walls. You can't keep the algae off...it is normal and healthy and should be left alone. But against any color, it looks bad. That's why pond liners are usually always black. The black will not be so dark once the water is in and the algae starts to grow.

Thanks to you all who answered ~ The pond guy was able to tint the 2nd epoxy coat a tan color - it looks so much better. Not sure what it will look like re the algae but I think it will be O.K.

I don't know why the pool place said you couldn't tint epoxy, but you can. We did and it looks good.

Thanks
