Types of Sealcoat Machines
Self-Propelled Squeegee Machines
Self-propelled squeegee machines are designed for large-area sealcoating tasks. With a standard capacity of 320 gallons, these machines mix and apply sealers efficiently. They often feature dual squeegees, allowing for even application and the ability to handle different types of sealant mixtures, including those with sand. Their ease of use and powerful performance make them ideal for commercial projects.
Sealcoat Trailers
Sealcoat trailers are a versatile option for both residential and commercial applications. They can be towed behind a vehicle and typically come in various capacities, making them suitable for different project sizes. These machines are built for portability, allowing contractors to efficiently move between job sites. Many sealcoat trailers feature integrated tanks and pumps for seamless operation.
Skid-Mounted Units
Skid-mounted sealcoat machines offer flexibility for various applications. These units can be mounted on trucks or trailers, providing a stable platform for mixing and applying sealants. With capacities that can reach up to 750 gallons, they are ideal for larger projects and can be customized to meet specific needs. Their robust construction ensures durability in demanding work environments.
Handheld Applicators
For smaller jobs, handheld applicators are a practical choice. These machines come in capacities ranging from 10 to 50 gallons, making them perfect for residential driveways or minor touch-ups. Their lightweight design allows for easy maneuverability, and they are generally user-friendly for individuals without extensive experience in sealcoating.
Crack Sealers
Crack sealers are specialized machines used for repairing cracks in asphalt surfaces. Typically holding around 10 gallons, these units can be equipped with heat lance attachments for effective crack filling. They are essential for maintaining the longevity of asphalt by preventing water infiltration and further damage.
Combination Units
Combination units integrate sealcoating and crack-filling capabilities into one machine. This multifunctionality allows contractors to handle multiple tasks in a single pass, improving efficiency on the job. They are particularly useful for larger projects where both sealing and crack repair are necessary.
