    Hi guys, how waterproof is epoxy/silica and epoxy/glass bubbles? Can you count on them to be completely waterproof or are they a bit porous and you should expect that some moisture can pass through?

    Thanks for all your help guys i really appreciate it!

    If the powders are well dispersed them it should be waterproof.

    Undisolved clumps of powder are not waterproof.

    A very thin layer may not be as waterproof as neat epoxy
