Concrete driveway sealing is an important step in protecting your home improvement investment. Answers to these frequently asked questions will help you make an informed decision when considering application of sealant.
Why Do I Need to Seal My Stamped Concrete Driveway?
Concrete is porous, and anything that is spilled on it will soak in. Sealing your driveway will protect it from water, oils, vehicle fluids and solvents from seeping into and penetrating your new surface. These fluids will damage and undermine the integrity of your concrete as well as diminish the aesthetic value.
What Type of Sealer Should I Use?
Factors to consider when selecting a sealant are sheen and whether it is water-based or solvent-based. Solvent-based products have a noxious odor and require solvents to clean up.
A penetrating sealant will soak into the concrete as opposed to a surface sealer. If you want a glossy finish, surface sealants will be the way to go. Penetrating sealants will result in a matte finish.
What Do I Need to Do to Prepare the Surface?
You need to thoroughly clean your driveway with a power washer or stiff scrub brush. Allow your driveway to dry entirely. Depending on the weather, this may take a day or longer. Sweep it again before beginning your driveway sealing.
How Long Will It Take to Dry?
It should take approximately 24 hours to dry. Always check your product label and instructions.
How Much Does it Cost?
You will have to get out your calculator. Measure and calculate the square footage of your driveway. Once you know the square footage check the product label to see what area it will cover. Determine how much product you will need to get the job done.
Can I Apply the Sealant Any Time of the Year?
It is best to avoid doing this job in the summer. Do not apply driveway sealant in the heat of the day. Early morning or evening is the best time of day.
What If It Rains?
You should seal your driveway when the weather is going to be dry for several days both before and after. Generally, it will only take about 24 hours to dry, so if you pay attention to the weather report, you should have an adequate window of opportunity.
Is Concrete Driveway Sealant Toxic?
There are non-toxic products available. These are generally the water-based sealants. Always check the product label for hazard and safety warnings.
What Tools Do I Need to Apply the Sealant?
A paint roller with an extension handle is an easy way to apply the sealer. Use a paintbrush to cut in around the edges just as you would when painting a wall.
Do I Ever Have to Seal It Again?
You should seal your driveway every 2 to 3 years.
What Do I Have to Do to Maintain It?
Keeping your driveway clean and free of debris is the best thing to do. Clean off any solvents or oils immediately.
