Design Engineering Boom Mat Deadening Spray – Spray-On Car Sound Deadener, 20 sq ft Coverage

Quiet, Calm Rides Begin with Boom Mat

The Design Engineering Boom Mat Deadening Spray is engineered to soften vibrations and reduce road noise, creating a calmer cabin that lets your music and conversations come through more clearly. It also supports enhanced stereo performance and overall vehicle acoustics, so you can enjoy every drive with less engine hum and more listening detail.

Built for interior and exterior use, this spray reaches into hard to reach spots and helps seal out moisture. The result can be a quieter ride with fewer rattles, while protection against rust is enhanced in vulnerable areas. The spray dries to a durable matte black pebble texture and can adhere directly to non-coated surfaces, making it a versatile choice for varied automotive applications. It also offers the option to top-coat with paint after a short dry time for a cohesive finish.

Key benefits at a glance

• Superior noise reduction eliminates road noise, squeaks, and vibrations for a more comfortable ride and clearer audio.
• Versatile application for interior and exterior surfaces, including hard-to-reach areas; helps seal out moisture and reduces rust risk.
• Quick drying and paintable finish; dries in about 20 minutes and can be painted over after 6 hours; adheres to non-coated surfaces.
• Extreme heat resistance up to 300°F, maintaining performance under temperature changes without cracking or peeling.
• Extensive coverage with one 18 oz can up to 20 sq ft; multiple layers are possible for added damping.

How to apply follows a straightforward workflow. Prep the surface, shake well, and apply in light, even coats. Allow each coat to dry before adding another. After roughly 6 hours, you can apply a top coat to blend with the vehicle color. The spray’s matte texture dries into a durable finish suitable for long-term use.

Tips for best results

• Work in a well-ventilated area with a steady spray distance for even coverage.
• Apply several thin coats rather than a single heavy layer to optimize damping.
• Let coats dry between passes; plan for a top coat after 6 hours if color matching is desired.
• It adheres to non-coated surfaces and dries to a textured surface that can be painted to match your color scheme.
