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.

It is good for small area, but not enough for larger area, need to buy many pens, but it is expensive

Great product

Excellent uplift to kitchen tiles. So pleased with the end result. Whitened the grout and made the tiles stand out looking new again. Will be ordering more to complete the bathrooms. The only issue is the pens only complete about 20 meters not 70 as described and you need to rest the pens upside down for the fluid to drain down. But otherwise happy with the product and have bought them again.
