Professional acoustical sealant for rated assemblies

DAP E90 SOUND BLOCK is a professional-grade latex sealant engineered to reduce sound transmission and improve STC ratings in wall and floor systems. It seals openings around electrical boxes, pipes, ductwork and utility penetrations. The formula suits both interior and exterior applications on a wide variety of building materials.

28 fl oz cartridge covers typical perimeter joints

One 28 fl oz cartridge provides sufficient volume for sealing perimeter edges, corner joints and cut-outs in standard assemblies. The non-sagging consistency stays in place on vertical surfaces without slumping. Coverage runs out on very large commercial projects requiring multiple cases of material.

Stays flexible and crackproof after curing

The sealant remains permanently flexible to accommodate building movement without cracking or losing adhesion. Cured beads accept water clean-up during application and maintain a durable bond to wood, metal, concrete and gypsum surfaces. Rigid joints that cannot tolerate any movement are not suited to this flexible formulation.

Questions about this item

Will the 28 fl oz cartridge bond to the existing drywall and wood framing I’m keeping?

Yes — the sealant adheres strongly to a wide variety of building materials, including drywall and wood, for both interior and exterior applications.

How can I confirm the E90 is performing as an acoustical seal after it cures?

It stays flexible and non-sagging, resists cracking, and is designed to improve STC ratings in rated wall and floor assemblies when applied around penetrations and perimeter joints.

Does the 28 fl oz white cartridge include a nozzle or do I need a separate caulk gun?

The cartridge is the sealant only; a standard caulk gun and a cut-to-size nozzle are required separately for application.
