Sealcoating is a process where workers spread a thin layer of asphalt on the pavement. It gives sun-bleached asphalt a fresh new look, fills in small holes and cracks and protects the surface from water intrusion and harmful chemicals.
Consistent application of sealcoat is a key factor in extending the lifespan and structural soundness of asphalt surfaces while circumventing costly repairs. Judicious maintenance demonstrates a steadfast commitment to quality. Visit https://www.rochesternysealcoating.com/ to learn more.
Asphalt pavement is a combination of rock and stone, held together with a binder that’s derived from the distillation process of certain crude oils. If left unprotected, sun and rain can cause the oxidation of your asphalt pavement, which degrades the binder and makes the surface brittle and cracked. Regular sealcoating slows the deterioration of asphalt and protects it from harmful chemicals, water penetration and harsh weather.
The most common mistake that property managers make when having their asphalt seal coated is hiring an inexperienced contractor or a contractor that “over sells”. If you want your parking lot or driveway to be protected properly, hire a knowledgeable professional.
Before your asphalt can receive a seal coating, it must be thoroughly cleaned of dirt and debris. Small cracks and chips need to be filled, and any oil spillage needs to be removed from the surface. After the surface is clean, it can be prepared for sealing by smoothing and leveling it. Then, once the sealant has been applied, it’s given a time to dry before vehicles are allowed on the surface.
When an experienced asphalt contractor applies the seal coat, it forms a protective layer against UV rays that can discolor and weaken asphalt. This barrier also prevents water penetration into the pavement, which can damage the base underneath. Sealcoat also acts as a barrier against chemicals that can damage asphalt, like salts, oil and gasoline.
During the sealcoating process, experienced contractors use coal tar emulsions that are safer for workers and the environment than other types of chemical-based products. However, it’s important to note that even coal tar emulsions have their downsides and can pose a health risk. When used improperly, they can lead to serious problems with the skin and respiratory system. If you are using coal tar emulsions, it’s important to wear protective clothing and equipment while working in the field. It’s also a good idea to limit the amount of time you spend on the road. If possible, stay off of it as much as you can until it has had a chance to fully dry.
Protects Wood
Wood sealers play a key role in safeguarding your wooden fence, furniture, deck, or other outdoor wood projects from the detrimental effects of moisture. Unprotected, wood is prone to swelling, warping, cracking, and decay. Fortunately, protecting wood from moisture with the application of a suitable wood sealant prevents such damage and extends the life of your project.
As an added benefit, wood sealants give wood a beautiful appearance. Unlike other types of wood finishes that will alter or darken the natural color of your wood, most sealants leave it looking its best. If you’re using a sealant with UV protection, the tinted finish will also provide extra protection from sun-induced fading of your wood.
Whether you choose to seal your wood yourself or use the services of a professional, a few important steps should be taken before beginning work. First, make sure that the surface is free of dirt, debris, grease, and small pebbles. This will ensure that the sealant will adhere properly. Additionally, any paint or coatings used to make lanes for driving or delineate parking spots will need to be removed as well.
Next, prepare the surface of your wood by cleaning it and sanding it down with a sander and foam sanding pad. Make sure to wear safety glasses during this process to avoid getting sawdust in your eyes. Finally, make any necessary crack repairs before proceeding with the sealing.
Once the wood is prepared, apply two coats of exterior-grade acrylic sealant with a paintbrush according to the product’s instructions. Allow each coat to dry completely before applying the next.
When choosing a wood sealant, look for one that’s low in VOCs (Volatile Organic Compounds). Some products use coal-tar emulsions or similar compounds that contain toxic chemicals. Alternatively, try Vermont Natural Coatings’ Penetrating Waterproofer, which uses whey proteins (a byproduct of cheese making) to create a long-lasting, zero-VOC waterproofer that’s safe for people and the environment.
When it comes to selecting a wood finish, there are plenty of options to choose from. Polyurethane is a high-performance option that’s especially suited for darker woods, while polycrylic matte finishes are great for lighter varieties.
Protects Concrete
Concrete surfaces are attacked by many influences that can cause damage to concrete including oil, chemicals, salt, UV rays and weather. Sealing concrete can help protect against these influences and allow the surface to look good longer.
Concrete that is not sealed deteriorates more quickly than untreated concrete. Untreated concrete can crack, spall, heave and discolor. When concrete is treated with a professional seal coat it can hold up much better to the elements and extend its life.
Sealing a concrete surface can help prevent moisture absorption and inhibit mildew growth. This can save time and money on maintenance as well as keep concrete looking nicer for longer.
When it comes to choosing the right sealant, there are many choices. Some of the most popular include coal tar, asphalt emulsion and water-based acrylic sealants. Coal tar is the most common type used in the United States. It is a black or dark colored substance that can be quite effective at sealing cracks and filling voids in concrete. It is also fairly easy to use and can be brushed or sprayed onto the concrete surface.
Asphalt emulsion sealants are made from a mixture of asphalt and other ingredients, such as petroleum products, water and fillers. They are typically used for protecting asphalt pavement from sun damage, water penetration and wear, as well as improving the appearance of the driveway. However, they are not as effective at protecting concrete from the elements and tend to wear down more rapidly than other types of sealants.
Water-based acrylic sealants are made from a combination of water and acrylic polymers. They are usually applied to concrete with a brush or sprayer and may be available in different sheens to enhance the appearance of the driveway. They are less effective than coal tar sealants at sealing cracks and filling voids but they do not leave a dark residue on the concrete.
No matter what type of sealant is chosen, it is important to prepare the concrete surface before starting the application process. This includes addressing any cracks, cleaning the surface and allowing it to dry completely before applying the sealant. It is also recommended that pedestrian traffic be restricted from the area until the sealant has had time to cure fully.
Protects Metal
The metal structure of your car would quickly rust without its protective coat of paint. The same is true of asphalt pavement that doesn’t have its sealcoating. When the sealcoating is worn away, the underlying asphalt pavement becomes exposed to oxidation, dirt, chemical substances that soften it, and even moisture which can lead to cracking. Sealcoating extends the life of asphalt and helps prevent the need for costly replacement.
Refined coal tar is one of the most common types of sealcoat used by professionals. However, this type of sealcoat is not very eco-friendly and can have a negative impact on the environment. Studies suggest that refined coal tar sealcoats can contribute to the accumulation of polycyclic aromatic hydrocarbons in streams and creek beds. Furthermore, it can also be harmful to fish and wildlife that ingest contaminated soil or dust from eroded coal tar sealcoats that have washed into waterways.
To minimize these risks, it is a good idea to opt for an environmentally friendly asphalt sealant rather than the more traditional coal tar based sealer. A few other benefits of choosing an eco-friendly sealer include a longer lifespan, better resistance to oil and chemical spills, and less environmental hazards.
Before applying the sealcoat, professional pavement contractors will thoroughly clean the pavement surface to remove all oil spots, dirt and debris. They will use robust cleaning equipment, including blowers, rotary brooms and sweepers to ensure that the pavement is as clean as possible. This is important as the sealcoating won’t bond to dirt or mud. The surface should also be swept to remove any noticeable cracks and lines.
