Sound deadening spray: spectrum liquid sound dampening material is a high heat, water based viscoelastic polymer, formulated and tested by Second Skin to adhere to metal and stop it from vibrating.
At 2mm thick, 1 gallon covers 20 SF. We recommend applying two layers of Spectrum Liquid Deadener to a total thickness of 2-3mm thicker than a quarter. Spectrum also works well on metal warehouse carts, boats, and HVAC ducts. It will not block or absorb airborne sound waves.
