An Inside Guide to Properly Sealing Granite Counter-Tops

One of the most frequently asked questions by owners of granite countertops is, “How often do I need to reapply sealant?” The information provided in this article is everything you need to know to first and foremost know when to seal your countertops as well as how to go about re-sealing them should the time come.

First off, make sure the company you choose offers a guarantee behind their product. Companies like DuPoint and Stonetech actually offer long lasting guarantees. This will ensure that you get a quality product. If the product isn’t up to your standards and staining occurs even after using sealant, you can rest assured that you won’t be paying for their mistake. Most granite companies will seal your countertops with a 1 year sealer. If they applied the sealer correctly, then at best you’re covered for 1 year, at worst 3-6 months. Either way, it’s integral that you take control of your countertop’s maintenance from that point onward. Looking for the longer lasting sealants will mean less hassle in your future.

So how do you know when to re-seal your countertops? This is probably the whole reason you’re here and the answer is the “Water Absorption Test.” It’s so easy to do and won’t cost you a penny. All you have to do is spill a few droplets of water onto a small area of your granite tops. If the water beads up to the point that you can actually blow the droplets along your tops, then all is well… no sealer is necessary. However, if after twenty minutes the water seeps into the granite, causing your granite to darken, then it’s time to re-seal.

To reseal your countertops, take these steps!

1. Buy an impregnating water-based sealer from your local builder supply store

2. Pour a decent amount of the sealer into a plastic cup or bowl

3. Apply flood coat to your countertops with paint brush or foam applicator brush

4. Allow sealer to seep in for about 5-10 minutes

5. Wipe clean with a microfiber rag

6. Wait at least 45 minutes and apply 2nd coat.

7. Conduct “water absorption test.”

8. If your tops pass the test, then your work is done. If not, then apply as many

coats as it takes to pass the test.

By maintaining proper care of your granite countertops, you can help ensure that your investment retains its value.
