How to Seal Granite Countertops

Hello, my friend, hello again; today we come together to talk about How to Seal Granite Countertops and hope the blog can help you.

Using the right sealant and techniques will help protect your kitchen investment for many years to come.

If you have a gorgeous granite countertop in your kitchen and want to keep it in “model home” shape, you may need to seal it. Some countertops are installed pre-sealed, but if yours was not (or you’re not sure whether it was), don’t delay giving it the protection it needs. Improper cleaning, neglected spills, and other effects of everyday use can easily mar its surface. A quality penetrating or impregnating sealer will soak into the granite, filling the porous gaps, and keep damage at bay. True, a sealant only buys you time—unattended spills will seep into sealed granite eventually—but the right product, and the following steps for how to seal granite kitchen countertops, will help protect your investment. 

Water-based countertop sealants are environmentally friendly, while solvent-based sealants may be a little better at penetrating the stone (this level of penetration is arguably only important on polished granite). When you’re shopping for the best granite sealer, it’s a good idea to check the labels of both water- or solvent-based sealants for the active ingredient fluorocarbon aliphatic resin. Though the product will be more expensive than those containing such agents as siloxane and silicon, fluorocarbon aliphatic resin will provide 5 to 10 years of protection, versus the 6 months to 3 years provided by other sealants. What’s more, fluorocarbon aliphatic resins repel oil and water, so your granite won’t be ruined by a salad dressing mishap. A quart of fluorocarbon aliphatic resin sealant, such as StoneTech BulletProof Sealer, costs about $55 and offers between 100 to 250 square feet of coverage, depending on the brand. A 24-ounce spray bottle of lesser solvent runs around $15 but might require reapplication every 6 months or so.

Ahead, you’ll find general guidance for how to seal a granite countertop with either variety of granite sealer, but specific directions vary according to brand and active ingredients. It’s crucial to follow the instructions on the sealant you buy in addition to these handy guidelines for the best results.
