Product Description
Willseal® 250 is a pre-compressed, self-expanding open micro-cell polyurethane foam impregnated with a hydrophobic, acrylic polymer sealing compound, coated with a factory-applied silicone sealant.
Willseal provides a watertight, dust-proof, airtight, noise-reducing, thermally insulating, and UV stable primary seal that does not require invasive anchoring for installation.
Use to quickly and permanently seal expansion joint openings between 2” and 6”.
Minimize lane closures: Install to Phoscrete expansion joint nosings as soon as 15 minutes following initial set of Phoscrete.
