I have had athe same quart of sealer last for 2 to 3 years, but I have marble or travertine tile in 4-baths as well as the granite counters. The granite just doesn't absorb much at all. You will be really happy with the granite and if there is any problem it is that granite lasts longer than your cabinets or appliances. I would hate to remodel around the counters because they would be difficult to move without breaking. Point being, be sure you get what you want and put it on top quality cabinets,or have it attached in a way that it is removable (minimize glue).
