Is Granite Porous

Will Granite EtchLemon Test - The lemon test is to determine the ability of your granite to resist etching.  Follow the steps below:

  • Place a wedge of lemon or lime, cut side down, on the sample overnight.
  • Wipe the sample in the morning and hold it at an angle to the light.
  • Check for a rough spot where the lemon was placed.
  • Etching will appear dull and rough.

Etches normally occur where calcium or calcite is present in the make-up of the stone.  If your sample reacts to the lemon wedge, we DO NOT recommend this for your kitchen.

Water Absorption Test - Test the suitability of your granite to resist water absorption.  The tighter the grain the less absorption.

Is Granite Porous Water AbsorbtionFollow these steps:

  • Place a few small drops of water on the sample.
  • Let stand for about 15 minutes.
  • Wipe excess water.

If the granite sample absorbed the water as soon as you put it on, DO NOT use this granite.  A quality sealer would help prevent some absorption, but would require constant maintenance.

If there is still a bit of water left on the surface, it will be suitable for your kitchen.  We recommend a sealer for all granite.
