Gran­ite needs stone sealing

Granite has become one of the most popular countertops in our homes today. 

Its natural beauty adds warmth, character and a level of elegance to your home or office, and it’s extremely durable. 

Granite can withstand extreme temperatures and is the hardest countertop material available. 

But how do you care for it?

Daily cleaning

To keep your countertops clean on a daily basis, use mild dish soap, warm water and a soft clean cloth. You can also use any water-based spray cleaner. 

It is not recommended to use any abrasive chemical on granite.

If film, smudges or streaks develop, use vinegar diluted with water (one part vinegar to three parts water) and a soft clean cloth to remove it.

Sealing granite countertops

Granite countertops should be sealed to maintain their best performance. 

Sealing works as a stain inhibitor and prevents most stains and soil from being absorbed into the surface. It’s not, however, a guarantee against staining.

Many fabrication shops will seal your stone before it arrives for installation. 

Some stones will only need sealing every few years depending on the stone’s porosity and your daily use of the countertops.

To determine if your countertop needs resealing, perform a water test. Place some water onto your stone. 

If within 15-20 minutes the water begins to absorb into the stone, it is time to reseal. Wait for the water spot to evaporate before resealing.

You will want to pick up a profess-ional stone sealer. Stonesealers are available through any stone/​tile retail location.

Application instructions

General sealing instructions are as follows, but always follow the directions provided with your product.

1. Be certain your countertops are clean and free of spills. Stains should be removed prior to sealing. You will need three clean, dry, soft cloths and stone sealer.

2. Pour a small amount of sealer, about the size of the bottom of a pop can, onto the countertop and distribute evenly with a dry cloth. Pour more sealer onto the stone as you move onto other areas of the surface.

3. Allow the sealer to penetrate the stone for two to three minutes. If the sealer is quickly soaked up by the stone, which is common with marble, limestone, travertine and onyx, repeat step 2.

4. Take another dry cloth and wipe the excess sealer off while it is still wet. If the sealer is already dry, apply a bit more and wipe it off. This will remove any residue.

5. Once all excess sealer is removed, use a clean dry cloth for a final wipe down.
