Henry Co HE587046 White Elastomeric Roof Coating 1 Gal

Product Description

The HENRY CO HE587046 is a high-solids, white elastomeric roof coating formulated with resins, fillers, and titanium dioxide pigments. It forms a permeable membrane that blocks liquid infiltration while allowing moisture vapor to breathe out of the underlying substrate. The coating releases 91% of absorbed solar heat, reducing thermal load on the roof assembly. It expands and contracts without cracking, making it well suited for roofs that experience thermal cycling. Installed by roofing contractors and maintenance professionals, this coating is applied directly to the substrate with no primer required on new roofs or roofs in excellent condition.

This coating is designed for use on low-slope and flat roof surfaces where solar reflectivity and moisture management are priorities. Typical applications include residential and light commercial roofing projects where an elastomeric, breathable membrane is needed to extend roof service life. The white finish provides high solar reflectance compared to economy-grade reflective coatings, making it a common choice for re-coating aged roofing membranes and metal roof surfaces requiring weather protection.

Key Features

• High-solids elastomeric formula expands and contracts without cracking under thermal cycling
• Releases 91% of the sun's heat energy, improving roof surface energy efficiency
• Permeable membrane allows moisture vapor to vent from the substrate while blocking liquid water infiltration
• Formulated with titanium dioxide pigments for high solar reflectivity and superior longevity vs. economy-grade coatings
• No primer required on new roofs or roofs in excellent condition, simplifying application
• White finish supports cool-roof performance on low-slope and flat roof assemblies

Compatibility

Designed as an OEM-style replacement-grade elastomeric coating for low-slope and flat roof substrates where a breathable, solar-reflective membrane coating is specified.

Installation Notes

Application is performed by qualified roofing contractors following local building codes and coating manufacturer application guidelines. The roof surface must be clean, dry, and free of loose debris, oil, or standing water before coating is applied. Verify substrate condition prior to application — primer may be required on roofs that are not new or not in excellent condition. Allow adequate cure time before exposing the coating to foot traffic or precipitation.
