Among the two most common methods of applying driveway sealers, spraying is preferred for its consistency and uniformity. Brush application relies heavily on manual techniques, such as squeegeeing and hand painting to apply the sealer evenly. But beware: excess sealer can cause cracks and breakage. Read on to discover the pros and cons of each technique. And remember: spraying is a faster and more economical alternative than hand painting.
Brushing asphalt sealer causes checkered appearance
Although it is tempting to brush asphalt sealcoat material onto the pavement, this technique has some drawbacks. For starters, brushing the sealer creates unsightly brush marks, resulting in a checkered appearance. Another drawback of brushing asphalt sealcoat material is that it does not restore the traction that the pavement lost during the application. However, the vast majority of brushing contractors do not use sand when applying the sealer to prevent the checkered look.
Asphalt sealer must be applied to a smooth surface, and you can do this by applying two thin coats or one thick one. A layer of sealer will ensure that the sealant penetrates the aggregates. If you do not notice any rainbows after the first coat, it is time to reapply the sealer. Remember to apply the sealer when the pavement and air temperatures are approximately 50F (10C) and above.
For a professional look, you should use a brush instead of a roller. When you use a brush, you can make your asphalt surface look smoother by squeegeeing. Brushing asphalt sealer causes checkered appearance, and can also cause cracks on the surface. A good sealcoating contractor will avoid this problem by brushing the surface and applying sealant in two to three years.
Fast-drying driveway sealer costs less than hand-painted seals
Applying a fast-drying driveway coating is a low-cost way to transform your driveway. A two-coat application of a high-quality driveway sealer creates a protective membrane for your concrete or other substrate. The process can be completed in one weekend. The driveway should be clean and dry; keep vehicles off it during application and leave your house for 24 hours afterward. Depending on the weather, the sealant may need 48 hours to completely set.
Before applying a driveway sealer, you must ensure two consecutive days of dry weather. It is important to choose a formula that dries quickly in 50 degrees Fahrenheit and above. It will also be ruined by scorching-hot days and heavy rain, so make sure you check the weather forecast. Otherwise, you may end up washing away your driveway coating and paying $100 for a paint job that didn’t last.
The cost of a driveway sealer project can be as little as $100 or more depending on the size of your property. The average cost to seal a 20′ x 24′ two-car driveway will cost between $100 and $190, depending on the number of cracks and the type of sealer you use. However, you may also need to pay extra for additional repairs and services.
Excess sealer can cause cracks and faster breakage
Driveway sealer comes in different grades and price ranges. Generally, bargain products contain nearly 50 percent water and offer lower coverage rates. Additionally, these sealants usually come with shorter guarantees. While they may seem cheap, they aren’t the best choice in the long run. In contrast, premium products use higher-grade resins, elastomeric materials, and fillers to provide greater protection and longevity.
Apply driveway sealer with a squeegee to make the application process easy. Start by applying a thin layer from one side of the asphalt to the other. Afterward, apply a second layer perpendicular to the first layer. When overlapping two layers, use a squeegee to spread the sealer evenly over both layers. Apply a second coat once the first coat has dried.
To get the best results, fill cracks only about 1/8 inch above the surface of the pavement. Keep in mind that excess sealant will not fill cracks and may cause the cracks to break down sooner. Make sure to clean the driveway thoroughly before applying the sealant. Excessive sealant will not bond to the surface, which is why you need to clean it thoroughly before applying it. Moreover, it’s important to mix the sealant thoroughly. Never mix it with a brush or stir stick. If you mix the driveway sealer properly, it will adhere to the surface of the pavement better.
