Novolac epoxy is one of the most chemically resistant and high-performance flooring systems on the market. It’s specifically designed to withstand harsh industrial environments where corrosive chemicals or aggressive cleaning routines are common. But while the product itself is engineered for durability, its performance depends heavily on one factor: proper installation.
That’s why hiring an experienced contractor is essential when it comes to Novolac epoxy. In this blog, we’ll explore what makes Novolac epoxy unique, the challenges that come with installing it, and why expertise matters when choosing a contractor for your project.
What Is Novolac Epoxy?
Novolac epoxy is a type of high-build coating made from phenolic epoxy resins. It’s known for its exceptional chemical resistance and thermal stability, making it ideal for environments such as:
- Chemical processing plants
- Food and beverage production
- Pharmaceutical facilities
- Laboratories and clean rooms
- Wastewater treatment centers
- Forklift charging areas
Unlike standard epoxies, Novolac systems can handle exposure to strong acids, solvents, and high heat without breaking down or discoloring.
Why Novolac Epoxy Installation Is Different
Installing a Novolac epoxy system is not the same as applying basic floor paint or even traditional epoxy. The material requires a deep understanding of surface prep, mixing ratios, environmental conditions, and coating thickness. Without that knowledge, you risk coating failure or underperformance.
Here’s why installation is more complex:
1. Precision Surface Preparation
Novolac epoxy demands an ideal surface profile to ensure proper adhesion. This typically involves shot blasting or diamond grinding to achieve the correct CSP (Concrete Surface Profile). A contractor without experience may over- or under-prepare the slab, leading to delamination.
2. Chemical Sensitivity and Mixing Ratios
Novolac coatings are highly sensitive to the exact resin and hardener ratio. An improper mix can result in bubbles, soft spots, or failure to cure. Experienced installers use precise measurement tools and understand working times to avoid these pitfalls.
3. Cure Times and Layering
Most Novolac systems require multiple coats, each with a specific cure time. Rushing the process or applying layers too soon can compromise the entire system. Experienced contractors know how to stage projects for optimal curing and long-term durability.
4. Environmental Conditions
Temperature, humidity, and ventilation all impact the success of an epoxy installation. A seasoned contractor will monitor and adapt the process to match the conditions on-site.
What Can Go Wrong With Poor Installation?
Hiring a general contractor or inexperienced team for a Novolac epoxy job can lead to serious issues:
- Blistering or bubbling due to poor surface prep or moisture entrapment
- Cracking caused by incorrect curing or improper thickness
- Peeling or delamination from poor adhesion to the substrate
- Chemical breakdown if materials are misapplied or contaminated
These problems not only lead to costly repairs but also jeopardize safety and compliance in sensitive environments.
How to Choose the Right Contractor for Novolac Epoxy
When evaluating contractors for a Novolac epoxy installation, look for the following:
- Experience with high-performance coatings: Ask for case studies or examples of similar installations.
- Proper certifications and equipment: Ensure they have access to industrial prep tools and safety procedures.
- Moisture testing and surface analysis: A reliable contractor will assess the concrete slab before starting work.
- Product knowledge: They should be familiar with your chosen Novolac product and be able to follow manufacturer specs to the letter.
- Willingness to walk you through the process: Good contractors are transparent, communicative, and ready to educate you.
