How to Use Granite Sealer

Maintaining your granite counter tops, floors and bathroom walls will ensure their longevity and beauty. Granite is a hard stone, but can become dry and porous over time, making it more prone to stains and scratches. Sealing your granite surfaces helps to preserve the longevity and protects your investment over the long run.

Things You'll Need

• Mask Rubber gloves Safety glasses Paint brush or old rag Sealer

Instructions

Sealing Your Granite

1. Clean the surface of the granite with a dry towel or broom. If there are any particulates on the surface they can potentially scratch the granite, as well as compromise your sealer bond.

2. Using the paint brush or your old rag, apply some sealer to the surface of your granite. Start with a small amount at first until you are comfortable with the process.

3. Work the sealer into the face of the granite with your rag. Do not leave excess sealer on the surface of the granite or it will create a haze.

4. Pay special attention to the corners and joints. If you are working with slab granite, you can seal the entire area without worry, but if you are working with a granite tile surface, be sure to coat the joints with liberal amounts of sealer to avoid water penetration.

5. Allow the sealer to dry per the manufacturer's instructions; this time varies, so be certain to read the label.

Tips & Warnings

• If you are sealing a small area, you may consider a spray-on sealer rather than use a rag or a brush. You can buy either a penetrating sealer or a surface sealer; they work equally well with granite.

• Be sure to open windows and doors in the area where you will be sealing. Wear a mask, gloves, and safety glasses for protection, as sealers (much like household cleaning products) can cause skin irritation in some individuals.
