Dynamat is a thin, flexible, easy to cut and mold sheet that actually stops noise causing resonance and vibration, by using visco-elastic qualities that promote vibro-acoustic energy conversion. In short, that means noise becomes silent energy..
You can apply Dynamat in patches (25-50% area coverage) to keep a specific panel from resonating or you can apply it over an entire area (such as the floor, doors, or trunk) to create a sound barrier and thermal insulator.
Step 1: Prep the Surface
Clean the mounting surface with a quick-drying, residue-free solvent. Remove all dirt, grease, oil, wax, moisture and rust to ensure a permanent bond between the Dynamat and the mounting surface.
Step 2: Size and Cut
Using a razor knife or scissors, cut the Dynamat sheet to the desired shape and size (you may find a cardboard or paper template helpful.) Remove the blue release liner from the back of the Dynamat and apply the Dynamat to the prepared surface. On large surfaces, remove the release liner in sections, working your way down and across the panel.
Step 3: Apply the material
Apply the Dynamat to the mounting surface with a Dynamat roller tool. Take the roller tool and work the Dynamat into all contours of the metal panel. Using a razor knife, poke holes in any air pockets that may have formed between the panel and the Dynamat. Work the air out with the roller tool. Eliminating air pockets ensures lasting adhesion to the panel to give maximum damping effect.
