WHY AN EPOXY PRIMER IS NOT OPTIONAL — IT’S THE FOUNDATION OF SYSTEM PERFORMANCE

WHY AN EPOXY PRIMER IS NOT OPTIONAL — IT’S THE FOUNDATION OF SYSTEM PERFORMANCE picture

One of the most overlooked causes of premature epoxy floor coating failure is the absence of a properly specified and installed epoxy primer system.

At Polymer Coatings Group Inc., the installation of a Polymer-Based Epoxy Primer is a non-negotiable part of our engineered flooring methodology — because a coating system is only as strong as the bond created with the substrate beneath it.

A quality epoxy primer plays a critical role by:

• Promoting deep substrate penetration and adhesion
• Binding residual surface dust and porous concrete particles
• Reducing the risk of delamination and coating failure
• Assisting with moisture tolerance and substrate stabilization
• Improving inter-coat bonding performance
• Enhancing the long-term durability of the entire flooring system

Without proper priming, even high-performance epoxy coatings can suffer from:

* bubbling,
* peeling,
* loss of adhesion,
* pin-holing,
* and premature wear.

In industrial, commercial and high-traffic environments, substrate preparation and primer specification are not merely “prep work” — they are part of the engineered protection system itself.

This is why we approach flooring and refurbishment projects from a life-cycle performance perspective rather than simply supplying a coating product.

We supply our Epoxy, Polyurethane and Hybrid Epoxy Coating Systems, only through our panel of approved applicators or otherwise, a customers' proven installation expert, for installation projects, for full compliance i.t.o. warranty conditions.

Specified Systems. Proven Performance.
