Behind the Science: Breaking Down the Adhesion Performance of Evercrown vs. Top Competitors
As you are probably aware, the chimney crown is a vital component that sheds rain and snow away from the masonry and protects the interior walls surrounding the exposed flue pipe from water damage. Since the crown is made of concrete, it is prone to cracking and fissuring, typically caused by house settling, snow accumulation, and extreme temperature swings.
Repairing cracks in the chimney crown typically requires patching the crown with mortar or a concrete mix and applying a water-resistant sealant. It’s a long, labor-intensive process as the mason must wait for the concrete to cure before applying the waterproof coating. Plus, the crown is still vulnerable to future damage. There are also other products, such as CrownCoat™ and CrownGuard™ HP, that simplify crown repairs but lack the adhesion performance of Evercrown®.
What is Evercrown®?
Evercrown is a professional-grade, proprietary bonding compound that combines the elasticity of rubber with the rugged durability of concrete. Because it is highly elastic, it stretches and shrinks during thermal cycles. Unlike its top competitors, Evercrown provides a seamless, water-resistant repair that protects the crown from moisture intrusion, shifting, and thermal expansion.
The Secret to Evercrown’s Adhesion Strength
The secret is its cross-linking polymer chemistry. These ionic bonds significantly increase its durability, structural integrity, and heat resistance. While traditional patches sit on top of the concrete, Evercrown forms a deep mechanical and chemical bond within the masonry’s microscopic pores. Evercrown’s viscosity allows it to be applied like cement with a trowel or brush, packing tightly into structural voids and sealing cracks up to ¼ inch wide. As it cures, it transforms into a flexible elastomer, a UV-resistant shield that moves with the chimney rather than against it. It’s like the wheels underneath a building that allow it to move during seismic shifts, preventing it from breaking apart during an earthquake.
Evercrown Vs. Top Competitors
When you compare an advanced elastomeric compound like Evercrown (and its direct professional competitors) to traditional chimney crown repairs, it is a battle between modern polymer science and old-school masonry. Here is how Evercrown stacks up:
Traditional Repair
Traditional mortar and poured concrete will repair the crown, but these porous patches inevitably shear, crack, and pull away from the old masonry surface. Furthermore, it requires the technician to make multiple trips to ensure the patch fully cures before applying the waterproof topcoat.
CrownCoat™
While CrownCoat provides an elastomeric barrier, it is formulated as a thin, water-based, brushable paint. Because it lacks a structural body, it cannot fill gaps on its own. Pre-filling every crack with a separate patch, caulk, or cement is mandatory. Evercrown eliminates this extra step by serving as both a structural crack filler and a flexible outer membrane.
CrownSaver™
This is a traditional cement-based, fiber-reinforced crown restoration mix. While it does a good job of repairing a crumbling crown, it remains fundamentally rigid. Exposure to heavy freeze-thaw cycles and foundation settling can still cause hairline cracks in fiber-mesh cement mixtures, so they often require a secondary waterproof coating.
