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.
