When it comes to protecting and enhancing concrete surfaces, standard paints often fall short, especially in high-traffic or industrial settings. This is where high build concrete coating systems step in, offering a robust and long-lasting solution that significantly outperforms conventional options. These specialized coatings are engineered to provide exceptional durability, chemical resistance, and aesthetic appeal, making them a crucial investment for a wide range of commercial and industrial applications.
Understanding High Build Concrete Coating Systems
High build concrete coating systems are characterized by their substantial thickness, typically applied in layers that are much thicker than standard paint or sealers. This increased thickness contributes directly to their superior performance and longevity. Unlike thin film coatings, high build systems create a durable, protective layer that can withstand significant abuse.
What Makes a Coating ‘High Build’?
The term ‘high build’ refers to the dry film thickness (DFT) of the coating. While specific definitions can vary, a coating is generally considered high build if it achieves a DFT of 10 mils (0.010 inches) or more in a single application. Some advanced high build concrete coating systems can achieve thicknesses of up to 125 mils or more, depending on the product and application method.
Key Benefits of High Build Concrete Coating Systems
Investing in high build concrete coating systems offers a multitude of advantages that translate into long-term savings and improved operational efficiency. These benefits address common challenges faced by concrete floors in demanding environments.

Types of High Build Concrete Coating Systems
Several types of high build concrete coating systems are available, each offering unique properties and benefits. The choice depends on the specific requirements of the application, including chemical exposure, traffic levels, and desired aesthetic.
Epoxy High Build Systems
Epoxy coatings are among the most popular high build concrete coating systems. They are known for their exceptional hardness, abrasion resistance, and strong adhesion to concrete. Epoxy systems provide excellent chemical resistance and are often used as a base coat or a full system in industrial settings.
Urethane High Build Systems
Urethane coatings offer superior flexibility, UV stability, and scratch resistance compared to epoxies. They are often used as a topcoat over epoxy systems to enhance durability, provide a matte or satin finish, and offer better resistance to yellowing from sunlight. Polyurethane high build concrete coating systems are ideal for areas exposed to UV light or requiring a more elastic surface.
Polyaspartic High Build Systems
Polyaspartic coatings are a newer generation of high build concrete coating systems, prized for their rapid cure times and excellent UV stability. They can be applied in a wide range of temperatures and achieve full cure within hours, significantly reducing downtime. Polyaspartics also offer high abrasion and chemical resistance, making them suitable for fast-track projects and outdoor applications.
Hybrid High Build Systems
Often, the best solution involves a combination of different chemistries. Hybrid high build concrete coating systems might use an epoxy primer for strong adhesion and build, followed by a urethane or polyaspartic topcoat for enhanced UV resistance, flexibility, and scratch resistance. This layering approach maximizes the benefits of each material.
The Installation Process: Key Considerations
Proper installation is paramount to the performance and longevity of any high build concrete coating system. A professional approach ensures the coating adheres correctly and performs as expected.
Surface Preparation: This is the most critical step. It typically involves diamond grinding, shot blasting, or scarifying to create a clean, porous profile that allows for optimal adhesion. Any existing coatings, contaminants, or repairs must be addressed thoroughly.
Crack and Joint Repair: All cracks, spalls, and control joints must be properly repaired and filled before coating application to prevent future issues.
Priming: A suitable primer is often applied to ensure excellent adhesion between the concrete substrate and the subsequent high build layers.
Application of High Build Layers: The coating material is applied in one or more layers, often using squeegees, rollers, or sprayers, to achieve the desired thickness and finish.
Topcoat (Optional but Recommended): A protective topcoat, often a urethane or polyaspartic, may be applied to enhance durability, UV resistance, and specific aesthetic qualities.
Curing: The coating must be allowed to cure completely before being subjected to traffic or chemicals. Cure times vary significantly depending on the product and environmental conditions.
Due to the complexity and importance of proper surface preparation and application techniques, it is highly recommended to engage experienced professionals for the installation of high build concrete coating systems.
Maintaining Your High Build Concrete Coating System
While high build concrete coating systems are inherently durable and low-maintenance, a simple cleaning regimen will help preserve their appearance and prolong their lifespan.
Regular Cleaning: Sweep or vacuum frequently to remove loose dirt and debris. Mop with a mild, pH-neutral cleaner and water to remove spills and grime.
Prompt Spill Cleanup: Address spills, especially chemicals or oils, immediately to prevent potential staining or etching.
Avoid Harsh Abrasives: Do not use abrasive cleaners, steel wool, or highly acidic/alkaline cleaning solutions, as these can damage the coating.
Periodic Inspection: Regularly inspect the floor for any signs of wear, damage, or delamination. Minor repairs can often prevent more extensive issues down the line.
Choosing the Right High Build Concrete Coating System
Selecting the ideal high build concrete coating system for your specific needs requires careful consideration of several factors. It is not a one-size-fits-all solution.
