What Really Damages Your Protective Concrete Coating?

Your investment in a durable protective coating is meant to last, but even the strongest resinous flooring faces hidden threats. Homeowners and business owners often overlook the everyday factors that lead to premature concrete coating damage. Understanding these four common culprits is the first crucial step in extending the life of your beautiful epoxy floor. Contact Custom Concrete Coatings to learn more!

Chemical Spills and Acidic Attack

Garage coatings are constantly exposed to corrosive materials like battery acid, oil, gasoline, and harsh cleaning products. These chemicals can penetrate and soften the protective coating, causing permanent discoloration, etching, or peeling over time. Our concrete contractors emphasize immediate cleanup to preserve the integrity of your finish and maintain its resistance qualities.

High-Impact Stress

While designed to be tough, consistent scraping from heavy equipment, dragging objects, or sharp impact from dropped tools can damage the surface. This mechanical stress compromises the seal, creating tiny weak spots that allow moisture and dirt to infiltrate. Selecting the right decorative coating thickness is vital for high-traffic or industrial concrete contractors projects.

Moisture Vapor Transmission from Below

A significant, yet often unseen, threat is moisture vapor rising from the concrete slab below the coating. High hydrostatic pressure can create blistering and delamination, separating the coating from the sub-surface. Experienced concrete contractors know how to test for and mitigate this issue before applying any durable, long-lasting resinous flooring system.

UV Exposure and Extreme Temperature Cycles

Exterior surfaces, like patios or pool decks, suffer from direct sunlight which can cause standard epoxy floor finishes to yellow or fade. Furthermore, rapid freezing and thawing cycles can cause the underlying concrete to expand and contract, leading to cracking in the concrete stain. Proper UV stability is essential for any outdoor protective coating application.
