Questions, answered about sealing the Granite Counters in your Denver kitchen.

To seal, or not to seal?  How often to seal? How to seal? The answers you’ll find to these questions are usually wrong. At Granite Imports we are granite specialists, and we will tell you the truth about sealing the granite counters in your Denver home.

To seal granite, or not to seal?

Sealing the granite counters in your Denver home is not always necessary, and certainly not as often as you may have been lead to believe. Many black granites, for example, are so dense that they are naturally water-proof and stain-resistant. Applying a sealer to them while, not a bad thing, doing it more than we recommend for that particular stone will leave a coating on the surface of the counter that starts to dull the shine. Most other granite counters are somewhat permeable, and sealing them will protect them until you can blot up spills. 

A caveat here – if you are using granite tiles for your granite countertop, the grout between the tiles must always be sealed, about 1-2 times yearly with standard residential use.

To find out if the granite counters in your Denver home need sealing do a simple test. Find an unobtrusive place on the granite counter and place a drop of water on the counter. After a few minutes, if the water darkens the granite counter, and starts to soak in, then you have a counter that needs to be sealed.

How often to seal granite counters?

If you test your Denver granite countertop and find that it needs sealing, it’s important to seal it as soon as possible to protect it. Do not believe claims stating that you need to reseal your countertop every few months. Use a good quality sealer like Dry Treat, and your counters will stay sealed for 5 – 15 years.

How to seal granite counters?

The first step in sealing your granite counters is to choose a penetrating sealer made especially for the granite counters in your Denver home. Use a soft, damp and lint free cloth and spread a light coat over the entire granite counter. Leave the sealant on as long as the product directions specify, long enough for the sealant to soak into the counter. If necessary, apply additional coats when the counter is nearly dry. After the final coat has permeated the counter, wipe of any excess with a clean cloth.

Give the granite counter 2-24 hours before you clean it. Sealants need minimal time to penetrate into the stone before they are effective.
