Can Mexican Beach Pebble be sealed to maintain black color?

It’s dark when wet then turns a gray blue when dry. I’d like to seal to maintain rich black color.

     A gentleman said he had used this product quite successfully. He made a sort of colander (old bucket) to put the rocks in and poured the product over to drain in the lower bucket. Laid them on a white sheet to dry.

    It’s called Cromellin. It’s Australian, but I’m sure there are similar products here.

    My sister picked up some beautiful, very colorful rocks at the beach while living in Greece for 2 years. But when they dried, they were very dull. She varnished hers.

    A marine grade varnish should work. Helmsman is great. Polyurethanes will spider crack and peel. Mod Podge may also work but not for outdoors.

    One of the most common uses of Mexican river rock, also known as Mexican Beach Pebbles, is in water features. These sleek, naturally rounded stones make excellent accents in and around pools, providing a comfortable surface for barefoot walking.
