How do I seal concrete items I have made andwhy is it so importent?

Concrete sealer is sold in your local hardware store. Wet a piece of Lambs wool with sealer and rub on your paper weights. Allow to dry according to directions on bottle.

Hope that helps

Sometimes concrete items will "dust" as they are handled. It is actually just the dried concrete powder coming off in tiny amounts. You can use any typical sealer...or you can even paint them if you like. Or, you can leave them as is, but just know they may leave a small amount of dust...and you may leave fingerprints from body oils if you handle them much.

If you go to your local hardware they'll show you so many options!

melody I would think it was to maintain color. Less of an issue if paper weight as that I presume is for indoors than a pained rock would last outdoors. I would think a spray on lacquer would be sufficient but not sure due to porous nature of rocks

Besides the dusting, concrete is porous and can absorb moisture which will breakit down over time. You can use Mod Podge to seal them. Water based polyurethane doesn't yellow. Clear glaze.
