Sealcoating is a preventative measure that helps protect asphalt pavement from severe damage like alligator cracks and potholes. It also helps fill in newly emerging or larger cracks before they become deeper and more costly to repair.

Oil and gas stains are not only unattractive, but they can also cause permanent pavement damage. Keeping up with your asphalt’s sealcoating prevents this damaging process from occurring and prolongs the lifespan of your blacktop. Visit Website to learn more.

Coal tar is a thick black liquid that contains high levels of polycyclic aromatic hydrocarbons (PAHs) which have been linked to cancer. It also releases toxic fumes during application and drying and can contaminate waterways and soil when it is eroded by rain or runoff. Due to health and environmental concerns, coal tar has been banned in many states, counties, and municipalities.

Asphalt emulsion is an alternative to coal tar sealcoat that uses asphalt cement, mineral ingredients, and polymers to increase its durability. It is a bit more expensive than coal tar sealcoat but offers similar results. Both asphalt emulsion and coal tar offer superior weather resistance, but the choice of one over the other will come down to your budget and the condition and age of your parking lot surface.

Unlike coal tar, which requires crews to wear full-body protective clothing and respirators, asphalt emulsion can be safely applied without the use of protective equipment. It has a much faster curing time than coal tar and provides better all weather protection. Its only drawback is that it may need to be reapplied more frequently than coal tar.

The most important difference between coal tar and asphalt emulsion is the binder that they are made from. Coal tar is a byproduct of the steel industry while asphalt emulsion is derived from the same petroleum products as gasoline and oil. As a result, asphalt emulsion is less prone to degradation from the elements and can withstand more traffic than coal tar.

Additives are a crucial component to any sealcoat mix, as they play a large role in the final appearance of your driveway or parking lot. They can affect the color, dry time, and performance of your sealcoat. Different additives can serve multiple purposes, such as improving abrasion resistance, altering the texture, and providing additional strength or flexibility.

Choosing the best type of sealcoat for your commercial property depends on the condition and age of your asphalt, your budget, and your maintenance expectations. It’s important to work with a professional sealcoating company that will be able to help you evaluate the condition of your asphalt and suggest which product will best suit your needs.

Oil-Based Emulsion

Asphalt is made by mixing rocks, stones and gravel with a binding agent that’s often petroleum-based. To help protect this asphalt, property managers use a seal coat to create a thin liquid layer of protection for the surface. Workers spread this emulsion over the pavement with sprayers, brushes and squeegees to fill in cracks and prevent the destruction of the asphalt underneath. The emulsion contains sand, polymer additives and other fillers and solids to increase slip resistance and the durability of the finished product.

The most common oil-based sealant is coal tar. It’s affordable, durable and binds to asphalt quickly and reliably. It’s also resistant to the destructive effects of weather, UV rays and chemicals, making it the best choice for commercial properties. However, the material is carcinogenic, and it can cause lung and skin problems for workers who come into contact with it. This is why it’s important to make sure that workers are well trained in the application and safe handling of these materials.

Coal tar emulsion also doesn’t offer the same level of resistance to gasoline and oil as other types of asphalt emulsions. While some manufacturers include additives to counter this issue, they don’t address it as effectively as other types of sealers. During the application process, coal tar emulsions emit a distinctive odor that can be unpleasant for people nearby.

For optimal results, the asphalt should be free of debris and dirt before workers apply the seal coat. It’s also crucial that the air and pavement temperatures are above 55 degrees Fahrenheit to ensure a successful bond between the emulsion and the asphalt. If these conditions aren’t met, the emulsion will start to melt and crack, and the parking lot will be vulnerable to further damage.

For the best results, parking lots should be closed for 24 hours after the squeegee or sprayer has been applied. This is to avoid tire marks and to allow the sealant to fully cure. It’s best to apply sealcoat during the warmer months when temperatures are consistently above 50 degrees.

Fast-Dry Emulsion

When you are sealing a large area, you might want to consider using a fast-dry emulsion. This type of sealcoating has a shorter drying time than traditional coal tar emulsions. This can be beneficial if you are trying to finish a project quickly, especially if the weather is not ideal for a sealcoating job. However, this doesn’t mean that you should skip the proper agitation of the sealcoating tank. Instead, just make sure to clear the suction port before using it again and invest in a manual agitator for your sealcoating tank to prevent blockages from occurring in the first place.

A quick-dry emulsion will still take a few hours to fully dry, but it is an excellent choice for projects that require a quicker turnaround, such as emergency repairs or commercial work. During the application process, it is crucial to keep the temperature of the asphalt as warm as possible to speed up the driest times and ensure that the sealcoating is applied in the best conditions.

It is also important to avoid applying the sealcoat on a day that is likely to rain or have high humidity, as this will slow down the drying and curing processes and could leave the surface of your driveway or parking lot with water spots or puddles. This can cause the emulsion to degrade, which may lead to premature wear and damage.

The amount of water, polymer additives and sand used in the mix design of the sealcoating is also critical to the desired performance of the finished product. Excessive quantities of these materials can significantly affect the resistance of the cured film to destructive elements such as salt, water and UV radiation.

When choosing the correct sand for your sealcoating, it is vital to select a grade that will produce a textured appearance and provide traction for vehicles. It is also a good idea to use sand that has been crushed and screened to a specific size range. If the sand is too coarse, it will create rough edges on the cured sealcoating, which can cause premature wear and damage.

Acrylic

Acrylic is a type of plastic known for being one of the clearest materials on the market. It is also highly durable and affordable, making it an ideal material for numerous applications. It is used in aquariums, submarine periscopes, airplane windows and turrets. Acrylic is more impact-resistant than glass and won’t shatter when broken. In fact, it can withstand up to 30 times more force than a standard window.

Like all plastics, acrylic is a polymer. A polymer is a large group of molecules that are linked together into a single substance, which has properties that are different than the individual parts. Specifically, the molecules in a polymer are linked with strong bonds that make it impossible for them to separate. This process is called free-radical polymerization. It is a common way to create the polymers that are used in sealcoatings, such as coal tar, asphalt and oil-based emulsions.

As the name suggests, acrylic is a clear polymer made of methacrylic acid. This polymer is created by using free-radical polymerization to form chains. To do so, one leg of the methyl methacrylate molecule breaks off and links up with the middle carbon atom of another molecule to start a chain. This continues until the entire molecule is in a long chain, which gives the plastic its strength and clarity.

The benefits of acrylic include high heat resistance, good electrical insulation and low chemical reactivity. These properties make it an excellent material for use in aircraft, automobiles and appliances. It is also a popular choice for signage, display cases and exhibits because of its transparency and durability. Acrylic is also used for security barriers and safety partitions because it can withstand up to 30 times more bullet force than glass. However, it is important to note that acrylic sheets do not have a high UL rating.

A variation of acrylic called modacrylic is often used in wigs, hair extensions, fake fur and some protective clothing because it is resistant to mold and mildew. The main difference between acrylic and modacrylic is that modacrylic contains the nitrile polymer, which can cause respiratory issues when inhaled or ingested.
