The short answer is that resealing at least once a year is best. However, test your granite by placing a small amount of water on it and letting it sit for 10 minutes. If the countertop darkens, it needs to be resealed. It is important to seal your granite every year, as this helps to fill the pores of the stone and avoid staining.
