Product Identity

Henry PG923W120 is a white roofing sealant supplied in a 1.9 gallon pail. The solvent-based silicone formulation is designed for patching and sealing tasks on a range of roof substrates. It is intended for professional contractors and building maintenance teams who need a ready-to-use material for repair work.

Suitability

The sealant adheres to acrylic coating, aged membrane roofing, concrete, existing asphaltic roof coatings, metal, polyurethane foam, single ply and smooth or granulated cap sheet. It applies in temperatures from 35 to 120 degrees F. Buyers who require a water-based product, a different colour, or a smaller cartridge format should look at alternative options.

Questions about this item

Will this 1.9 gal white sealant bond to my existing acrylic coating and aged membrane roofing without a primer?

Yes, the product specifications list acrylic coating, aged membrane roofing, concrete, existing asphaltic roof coatings, metal, polyurethane foam, single ply, and smooth BUR or cap sheet as compatible surfaces for direct application.

How can I confirm the sealant is curing properly after I apply it in 35 degree weather?

The sealant is rated for application temperatures from 35 to 120 degrees F; proper curing will show a uniform white finish that remains flexible and adheres firmly to the substrate without cracking or peeling once fully set.

Does the 1.9 gal pail include a brush or roller, or do I need to buy application tools separately?

The pail contains only the solvent-based silicone sealant; brushes, rollers, or other application tools are not included and must be purchased separately.
