Yes Grout Pen is waterproof. Grout Pen is specifically design for wet areas including showers, bathroom floors, around sinks, kitchen counter and backslash. LOOK BRAND NEW AGAIN: Skip scrubbing tiles and use Grout Pen to paint and recolor your grout for a bright clean appearance USE ANYWHERE: Ideal for the bathroom, kitchen, and any other room that has floor or ceiling tiles LONG LASTING INK: Tackle small or large DIY projects with a pen that covers up to 150 feet of thin 2mm grout RICH PIGMENTS: Grout paint markers available in 11 different colors with reversible 5mm Narrow or 15mm Wide nibs ADVANCED FORMULA: Non-toxic, water-based ink that covers grubby grout stains making it look brand new again

Can you put sealer over it?

Nope. It looked beautiful until I put a sealer over it. (I should have searched for "sealer" before I even bought it. :-( ) Don't waste your money.

Does it work on silicone caulk?

Silicone caulk is not paintable so this product would likely not work on it.

does it work on marble tiles grout?

Yes, it works on grout, but it does not last long. I would guess a white sharpie would work just as well.
