Franklin 10.1 oz Titebond Duramaster High Performance Sealant White - (Box of 12)

Titebond® DuraMaster Sealant is the first Class 100 water-based sealant, combining fantastic adhesion and extreme elasticity, for a top-performing, lasting sealant. DuraMaster is great for use indoors and outdoors; on windows, doors, trim, siding, and even large gaps up to 2” wide. DuraMaster stays permanently flexible and is crackproof, ensuring the sealant expands and contracts with temperature changes. DuraMaster goes beyond the ASTM C-920 spec, performing at a Class 100 level, whereas most sealants only meet Class 25 or less. DuraMaster: MAXIMUM PERFORMANCE.
