How Do I Know My Granite is Sealed?

Keeping a seal on natural stone is essential for it's maintenance. A good sealer will defend against stains and mold by preventing liquids from penetrating the stone's surface. If the sealer wears away or is degraded by substances such as bleach or lemon juice, how can we make this fact apparent to the naked eye?

There is a simple test to discover if a stone is properly sealed or not, and it is virtually free.

Using a spray bottle, squirt plain water onto the surface of granite, marble, travertine, or any natural stone surface.

Beaded water on sealed granite does not soak into stone.


If the water beads on the stone and does not soak into the stone at all, the seal on the stone is good. Water will bead when it cannot soak into the surface beneath it.

If the water eventually soaks into the stone, leaving a slightly darker mark where the water has soaked in, you have unsealed or improperly sealed stone. The best action at that time is to find the proper sealer that is suited to your purposes and seal the granite, marble, travertine, etc.
