Why Do Pavers Turn Gray? (The Science)
Most homeowners assume that rain or snow washes the color out of their driveway. That is false. The real culprit is the sun.
​
Concrete pavers gain their color from Iron Oxide Pigments. When these pigments are exposed to constant Ultraviolet (UV) radiation, they undergo a process called photodegradation. The chemical bonds break down, causing the deep reds, browns, and charcoals to bleach out, leaving behind the natural gray color of the concrete cement.
Pro Tip
UV rays bleach concrete pigments. Without protection, the sun turns pavers gray. A sealer with UV inhibitors acts as a physical barrier to retain vibrant color.
Sealer is "Sunscreen" for Your Hardscape
Just as you wear sunscreen to protect your skin, your patio needs a protective barrier. At Chicagoland Paver Sealing, we use sealants fortified with advanced UV Inhibitors.
-
The Barrier: The sealer sits on top of (or penetrates into) the paver, absorbing and reflecting the harmful UV rays before they can attack the pigments.
-
The Result: The color stays vibrant for years instead of fading in months.
The "Florida Standard" of Protection
We have a second office in Florida, the UV capital of the United States. For many years, we've protected driveways & patios from intense, year-round tropical sun exposure. We bring those same extreme-climate standards to Glen Ellyn and the Chicagoland Area. Most local sealers are built for snow; ours are built for snow and sun. We don't use "off-the-shelf" products that break down under UV light; we use commercial-grade synthetics designed to last.
Can Faded Pavers Be Saved?
If your pavers are already faded and gray, is it too late? Usually, no. While we cannot chemically "inject" pigment back into the stone, we can often restore the appearance of the color using a Water-Based or Solvent-Based Wet Look Sealer.

-
How it works: Think of a wet pebble on a beach. When dry, it looks dull. When wet, the colors pop. Our solvent sealers permanently mimic that "wet" effect, drawing out whatever pigment remains deep in the pore structure of the stone.
Frequently Asked Questions About Sun Damage on Pavers
-
Why have my pavers lost their color?
-
Pavers lose color due to "photodegradation." The sun's UV rays break down the iron oxide pigments in the concrete, causing the surface to bleach out and return to its natural cement-gray color.
-
-
Does sealing pavers prevent fading?
-
Yes. High-quality sealers contain UV blocking agents that act as a shield. While no outdoor material is immune to the sun forever, a sealed paver will retain its color significantly longer than raw stone.
-
-
Can you restore the color of old, faded pavers?
-
In most cases, yes. We can apply a color-enhancing "wet look" sealer that deepens the tone and brings contrast back to washed-out bricks.
