DuraMaster Sealant
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.

Physical Properties
Do not apply on exterior surfaces if rain is expected within 24 hours.
Air, sealant, and surface temperatures should be 40˚F (4˚C) and rising.
Protect from rain for 24-48 hours after application. Dry time may be
extended in humid or cold conditions. Painting may occur within 2-4
hours after application with a high-quality water-based (latex-based)
paint. For other paint types, a compatibility test is recommended. To
ensure neat sealant lines, mask areas adjacent to joints. Always apply
sealant in a bead form. Once sealant is dry to the touch and does not
transfer, remove masking tape. If joint depth exceeds 1/2”, use backing
material. NOTE: Highly recommend using backer rod/backing material
for all joints. Not designed for continuous submersion or use below the
waterline. Store unused product in dry location at or below 70˚F (21˚C).
Not for use with nail holes or butt joints. For questions, please call our
