How do I test my outdoor granite countertops for sealant?

 

I have recently renovated my outdoor bar countertop; it is now granite.

 

I didn’t think to ask at the time about whether or not it has been sealed or if it needs to be at all.

 

How do I test to see if it has/or hasn’t been sealed? Is it really necessary for the winter months if I will be covering everything up?

Firstly, you should inquire if it was professionally sealed on the onset. 

 

Whether your stone is indoors or outdoors, to test this, put a good bead of water on your countertop where you do the most work and walk away for 20 minutes or so, and then check the bead. 

 

If the color of the granite is darker underneath the bead, it’s time to seal.  If the bead of water has flattened, it’s time to seal.  Generally, fabricators will seal the stone as they install; but it’s always a good point to ask them.

 

Simply ask your fabricator whether or not they sealed it and keep it up yourself whenever necessary. 

 

Interstone recommends Fila brand sealers and cleansers.
