Maryland: Asphalt Sealcoat Industry Standards and Regulations

If you’re sealing pavement in Maryland, there’s more to the job than just applying product and calling it done. Regulations and standards matter—especially if you want to protect your work, avoid fines and give your clients results they can trust. Whether you’re a sealcoating contractor, a community manager or a property owner, understanding the rules of the road is key. Let’s break down what you need to know about Maryland asphalt sealcoat standards and how to make sure your projects check every box.

What Maryland Asphalt Sealcoat Contractors Need to Know

Maryland takes asphalt safety and environmental impact seriously. Over the last several years, the state has followed growing national momentum to restrict coal tar-based sealers due to their high levels of polycyclic aromatic hydrocarbons (PAHs). These chemicals are known to pollute stormwater and pose health risks to people and wildlife. Maryland hasn’t issued a full statewide ban yet, but many cities and counties have moved to ban or discourage the use of coal tar sealants.

Instead, Maryland encourages contractors to use alternative sealers like asphalt-based emulsions and environmentally safer options. That’s where Pitch Black comes in. Pitch Black is a non-toxic, PAH-free asphalt emulsion that meets all regulatory expectations in Maryland and across the country. It’s water-based, easy to apply and built to last without harmful chemicals or heavy odors. If you’re working in areas with environmental restrictions, or simply want a safer, longer-lasting product, it fits the bill.

Maryland also follows federal and state-level stormwater management rules. When sealcoating near storm drains or water runoff areas, contractors must take steps to prevent sealer from entering waterways. That means using containment methods, following dry weather application guidelines, and keeping an eye on proper cure times.

In addition, Maryland recommends regular sealcoating every two to three years for commercial lots and roads to protect asphalt from weather damage, oil spills and daily wear. Following this schedule can help you stay in compliance and avoid early repairs.
