Industrial coatings
A high-temperature inorganic sealant that fuses with CeramycGuard™ to form a glass-phase layer (a hard, glass-like ceramic skin), protecting concrete against fire and extreme radiant heat.
Concrete under fire, intense sun or high-temperature industrial conditions faces thermal loads that standard coatings cannot survive. CG HeatShield™ is a high-temperature penetrating inorganic sealant formulated to handle exactly those conditions.
Applied over a cured CeramycGuard™ base, it fuses with the ceramic surface to form a durable, heat-tolerant glass-phase layer. It seals the concrete against corrosion at the pore level and shields that surface from fire, radiant heat and thermal shock. Independent testing by Surface Optics Corporation puts its Solar Reflectance Index (SRI) at 70, so the surface stays cooler in direct sun. Neither layer delaminates under thermal cycling.
Two-product system
CG HeatShield™ does not work alone. It is the second layer of a complete protection system. CeramycGuard™ is applied first, bonding chemically to the concrete and sealing the pore network. Once cured, CG HeatShield™ is applied over it, adding the high-temperature glass-phase heat and fire resistance that standard coatings cannot provide.
Chemically bonds to the concrete surface, forming an alumina-zirconia-silicate composite skin that seals the pore network and prevents corrosive agents from reaching the reinforcing steel beneath.
Applied over the cured CeramycGuard™ coat, it fuses with the ceramic surface to add a high-temperature glass-phase layer that resists fire, radiant heat and thermal shock without delaminating from the substrate.
Recommended uses
Protects concrete surfaces in wildfire-prone regions and fire-risk buildings against flame and radiant heat.
Guards concrete plinths, hearths and floors adjacent to high-temperature furnaces, kilns and process equipment.
A Solar Reflectance Index of 70 keeps treated surfaces from heating up in direct sun, reducing thermal load on the structure.
Shields concrete in zones exposed to process heat, flaring events and accidental thermal release.
Common questions
No. CG HeatShield™ is designed as a top-coat applied over a cured CeramycGuard™ base. The two products work as a system: CeramycGuard™ provides the chemical bond to the concrete and seals the pore network, while CG HeatShield™ adds the high-temperature glass-phase heat and fire resistance layer on top.
The CeramycGuard™ and CG HeatShield™ system is engineered for fire exposure and extreme radiant heat. Independent testing by Surface Optics Corporation, to ASTM C1549, ASTM E408 and ASTM E1980, measured a solar reflectance of 0.578 and a thermal emissivity of 0.951, giving a Solar Reflectance Index (SRI) of 70.

We hold no blast test data and publish no blast performance figure. What we can give you is design intent: the layer is built from microscopic ceramic shields that overlap each other, a structure intended to dissipate blast force rather than let it reach the concrete. We do not currently have a way to reproduce a high-energy shockwave, so that intent is unverified by test. Every performance figure we do publish for this product is thermal. Talk to our technical team if blast exposure is part of your application.
CG HeatShield™ is applied by brush or roller over a fully cured CeramycGuard™ coat. Surface preparation and cure intervals between coats are specified in the Technical Data Sheet. Application follows the same contractor process used for CeramycGuard™.
