Sealant Problem

[raymondsmindjob]

I recently built a paludarium and I used a clear (non-toxic) acrylic sealant to waterproof the background and waterfall.
After cycling the water for about 24 hours, the "clear" sealant started turning a milky white color on the waterfall and underwater sections of the project.

I do not want a spotty milky white water feature, so does anyone know of a non-toxic sealant or epoxy that will stay 100% clear when wet?

I use an epoxy intended for the "flood-coat" finish on tables and bars. It is sold under the brand name "Parks Super Glaze," and I got it from either Home Depot or Lowes for about twenty dollars. See the box second from the right in this photo:


This product seems to be completely impervious to water and shows no signs of whitening or softening.

In the essence of saving money, the solution I used to fix this problem was to mix paint with the sealant, then painted over my water feature with the mix. This worked beautifully and prevented any more white spots appearing.

Next time I buy sealant I will remember your tip, thanks!
