Noise Reduction Uses...
Whether you are looking to quiet down your hot rod, or make your daily driver comfortable as a luxury car, Spectrum Sludge has proven to be the easiest most efficient vibration paste on the market.
The majority of reducible noise in any car is structure borne, meaning it comes from vibrations, like a wind chime. Unlike wind chimes however, our cars are not tuned to any specific musical frequency, so what we end up hearing is the road noise, engine rumble and exhaust drone.
Stopping the vibrations on your cars metal panels is much like stopping a noisy wind chime with your hand. Once the vibrations stop, the noise stops.
Traditional noise mats are mostly inefficient mass loaders; heavy & foul smelling tar boards that work by adding weight to the car to quiet it down.
Because Spectrum Sludge is a curing polymer, it won`t chip or crack under extreme temperatures or abuse, making it perfect for use as an interior coating or as an undercoating.
When you purchase Spectrum Sludge, you will get 2 containers. The first is a regular gallon of Spectrum, and the second is a small bottle of Sludge Activator. Simply mix the activator in to the gallon of Spectrum to increase the viscosity to the thickness of your liking. The more Activator you add, the thicker it will get. Spectrum Sludge is too thick to be applied with a gun, so a paint brush or putty knife is ideal.
Activator will not make Sludge dry or harden any faster than normal. It will simply thicken the viscosity from the point of chocolate syrup to peanutbutter.
Mobile Audio
If you have an aftermarket, sound system, then you know that a lot of the musical energy is spent, and even wasted by vibrating and flexing the your cars metal panels. Not only are these vibrations loud, and obnoxious, but they also limit the potential of your stereo.
Since it is a vibration damper it will obviously reduce the panel vibration caused from your speakers allowing your music to sound clearer. It also strengthens the cars panels.
With stronger, non flexing panels, the energy is no longer being wasted and stays inside the car, making your music louder, clearer and less obnoxious to those around you.
Thermal Insulation
Anything you place in front of the heat source will help reduce or slow down the heat. Spectrum Sludge will help reduce heat to a small degree but is not specifically designed to do so. Any heat reduction noticed from Spectrum Sludge is purely a side benefit, not an intended result.
If you are looking for a thermal insulation coating, check out our ceramic loaded polymer Firewall or one of our self adhesive insulation mats; Damplifier or Damplifier Pro.
FAQ
What is the difference between Spectrum & Sludge?
Spectrum and Sludge are nearly identical. The only difference is the viscosity. Spectrum has the consistency of heavy chocolate syrup and is easy to spray, brush or roll on. Sludge has the consistency of peanut butter and is too thick to spray, but can easily be applied with a putty knife, trowel or paint brush.
How long does Spectrum Sludge take to cure?
like all water based products Spectrum will take 30 full days to cure but will be dry to the touch in 30-60 minutes and mostly dry within 1 week.
When can I put my upholstery back in place?
We suggest that you allow a minimum of 2 days for Spectrum Sludge to dry before reinstalling your upholstery.
What is better, Spectrum Sludge or Damplifier?
Both products are designed to do the same basic function; reduce noise through the reduction of vibrations. Both have their place, and both excel at specific frequency ranges. This is why we suggest using a combination of damping mat and coatings.
We suggest using Damplifier Pro as your base foundation inside the car, on all the panels hidden by upholstery, then use Spectrum Sludge as an undercoating on the underside of the cars floor pan. This will sandwich the sheet metal floor between Damplifier Pro & Spectrum Sludge, allowing for the ultimate approach in vibration deadening.
Does Sludge Activator speed up the curing time of Spectrum?
No. Sludge Activator is only a thickening agent, not a curing or hardening agent. With or without the Sludge Activator, Spectrum will have a shelf life of 6 months once opened and will cure in 30 days once applied.
