Seal Your Concrete Garage Floor 

You know that the concrete floor in your garage is exposed to all sorts of harmful materials which cause corrosion and deterioration of the floor.  These harmful materials can be attributed to the road salt, oil and other automotive fluids that come in contact with the garage floor. 

You want to protect your garage floor from stains and damage and you want to make cleaning and sweeping the floor easier. You can help protect your garage floor by applying a clear acrylic concrete sealer. These same acrylic sealers can be used on concrete walks and driveways.  The sealer can also be used as a primer under acrylic or polyurethane floor paints.  However, you cannot apply a sealer over paint or other coatings. 

You can hire a professional to apply the sealer to your garage floor.  Or, you can do it yourself.  If you choose to do the sealing of the garage floor yourself you need to take some precautions. 

You should wear protective gear to avoid damage to your eyes, lungs and skin. Use neoprene rubber gloves, goggles and a respirator with both organic-vapor and solid=particle filter cartridges.  While you are sealing the floor you need to continuously ventilate the garage.  Keep all the doors and windows open and use a fam.  

In addition to protective clothing you will need some tools such as a stiff brush, a bucket, a paintbrush, a paint roller with extension handle and tray, medium nap roller covers, a concrete cleaner. a concrete degreaser, and the concrete sealer. The usual estimate for the concrete sealer is one-half gallon of sealer for approximately 100 square feet. 

Your floor must be free oi dirt, grease and oil before you can apply the sealer, so you first have to clean the floor.  Following the directions on the products, use a stiff brush to apply the cleaner and degreaser.  Allow the solution to stay on the floor for 15 to 20 minutes after scrubbing.  Stubborn stains may need more time.  Then rinse the floor thoroughly with clear water.  You may need to repeat the process cleaning several times. 

Once the floor is clean and has dried thoroughly you can apply the sealer.  Test the sealer in an inconspicuous area before applying it to the entire floor.  Uneven density in the concrete floor may cause a light or dark appearance which may be objectionable, so you want to do a test spot first.   

The easiest way to apply the sealer is to use the medium-nap paint roller with the extension handle.  Start sealing the floor in a rear corner and continue to work your way out of the garage.  Allow the floor to dry as indicated on the sealer product container.  Usually it takes a few hours for the sealer to become dry.  Stay out of the garage and off the floor until the sealer is dry. 

If you are using the sealer for a driveway the procedure is pretty much the same.  If you have a large driveway it will be quicker to use a garden sprayer to apply the sealer.  When using a sprayer to apply the sealer use caution so you do not over-spray it on other materials which may become stained.
