There are several things we understand to be true about sealing granite...  Since granite is a naturally porous material, it does need to be sealed to prevent fluids from penetrating into the material.  Quality and effectiveness of sealants vary greatly -- less effective sealants need to be applied more frequently.

All SITK granite is treated with 10-year commercial-grade sealant, so our countertop customers do not need to be concerned about frequent re-sealing.  We recommend occasional use of a cleaner-polisher available at our store -- but this is not a re-sealer.

Manufacturers of quartz and acrylic-polyester countertops often seem to encourage concern among "granite-shoppers" about troublesome granite-maintenance chores.  While SITK sees various product benefits and limits for each type of countertop material, we do not see granite-sealing issues as important in our customers' material selection process.
