A driveway is obviously an important surface when it comes to the exterior of your home. Most of us take them for granted until it comes time to make costly repairs. In areas of the country that see cold winters, salt and erosion can be a huge problem for a driveway. Salt can eat away at the surface of concrete causing chipping and erosion issues. Moisture can also penetrate the driveway and create freezing and thawing damage in as little as one harsh winter season.
To protect your driveway from salt and erosion it is best to seal it. Sealing a driveway will stop most of the damaging effects of winter weather. The sealer will repel moisture and salt so the driveway surface is not harmed. When it comes to sealing a driveway there are a few steps necessary for a successful result. When the weather is appropriate for applying a sealer prior to winter, the surface should first be cleaned. Use a quality concrete cleaner along with a pressure washer to remove dirt, grime, mold, and mildew. The concrete cleaner will help break down these contaminants including tannin stains from sticks, leaves, and acorns so the surface is completely clean prior to sealing.
Once you clean the driveway you should let it air dry for 1 to 2 days. Now you are ready to apply the driveway sealer. This can be accomplished by using a brush, roller, or garden type pump sprayer in most situations. There are many different types of driveway sealers but it is best to apply a penetrating type sealer. Do not apply more sealer than the concrete can absorb. Start in a small area of the driveway to get familiar with the amount of sealer that needs to be applied. If sealer is not absorbed after 10 to 15 minutes back brush or wipe the excess away. Do not allow excess puddles to dry on the surface.
Always follow the manufacturers application instructions. Multiple coats may be necessary depending on the porosity of the driveway. Following these guidelines and knowing how to seal driveways from salt and erosion can save you a lot of money down the road by avoiding costly repairs. Protect your investment and safeguard your driveway from salt and erosion.
