Choosing the right top coat is one of the most important decisions when installing an epoxy flooring system. The top coat determines durability, gloss level, chemical resistance, UV stability, and overall performance.

Simiron offers several high-performance top coats designed for different environments and finishes. In this guide, we’ll break down the key differences between the most popular Simiron top coats and help you decide which one is right for your project.

Why the Top Coat Matters

The top coat is the final protective layer of your epoxy floor system. It is responsible for:

• Protecting against abrasion and wear

• Resisting chemicals and stains

• Providing UV stability (preventing yellowing)

• Controlling gloss and appearance

• Extending the life of the floor

Choosing the wrong top coat can lead to premature wear, discoloration, or costly repairs.
