Henry Co HE289046 White Elastomeric Roof Patch 1 Gallon

Product Description

The HENRY CO HE289046 is a white elastomeric roof patch mastic designed for sealing and repairing roofing surfaces where white acrylic coatings are present. Sold under the Solar-Flex line, this product delivers flexible, weatherproof adhesion across common low-slope and flat roof substrates. It functions as a caulking and patching compound in one, filling cracks, seams, and penetrations before or after a white acrylic topcoat is applied. Roofing contractors and commercial service techs use this mastic for maintenance repairs on EPDM, modified bitumen, and coated metal roof systems. Each container holds 1 gallon and is packaged 4 units per case.

This product is suited for both residential and commercial roofing applications where a white or reflective roof system is in service. It is commonly applied around flashings, vents, skylights, and seams as part of a maintenance or restoration program using white acrylic coating systems. The mastic stays flexible after cure, which allows it to handle thermal movement without cracking. Roofing professionals apply it as part of a two-step process: patch and seal with this product, then topcoat with a compatible white acrylic coating to complete the repair.

Compatibility

Designed for use with white acrylic roof coatings as part of a patch-and-coat roofing restoration system. Verify substrate and topcoat compatibility with the coating manufacturer prior to application.

Installation Notes

Application is typically performed by licensed roofing contractors following local building code and manufacturer surface preparation requirements. Clean and dry the substrate thoroughly before applying the mastic — moisture or debris will compromise adhesion. Apply using a trowel, putty knife, or caulking tool depending on the repair geometry, and allow adequate cure time before applying any topcoat. Do not apply to wet surfaces or during freezing temperatures unless the product label specifically permits it.
