Use a spray gun with a 2mm nozzle to spray Spectrum.The shorter tube (3.25") is for applications where the gun is held upside down. The longer tube (7.25") is used if the spray gun will be held right-side up.
The Second Skin spray gun comes with two tubes that are screwed into the middle of the circular area where the bottle screws into the gun.Wait 7-10 days before painting or covering with a bed liner.Īdvice on a Clean Install and Easy Cleanup Spectrum can be painted, but you must wait for it to completely cure.Wait 24-36 hours before installing another product or upholstery on top of Spectrum.Once you can touch Spectrum with your finger without residue, you're in the clear for the next coat. As Spectrum dries, its color changes from dark blue to black.Getting the base coat right is key for proper adhesion, as you can often be a bit more aggressive on subsequent coats. If worried about time-to-dry, apply in thinner layers - especially the first coat.The worst combination is low temperature AND high humidity.
A high humidity will increase the expected dry time. To help Spectrum dry faster, increase the overall temperature in your garage or roll the vehicle out into the sun. We do not recommend that you apply targeted heat to Spectrum. Dry speed improves substantially as temperatures are above 70☏. The higher the temperature, the faster Spectrum will dry. The ambient temperature should be at least 50☏ for the first 24 hours after application. Three factors impact how long it takes for Spectrum to dry: (1) temperature (2) humidity (3) thickness applied. There's an especially big increase in the first 48 hours.Īdvice on Spectrum's Dry Time and Application Strategies Spectrum's deadening performance will continue to improve over the course of the 7 day cure cycle. If you expect longer than usual dry times, we recommend thinner layers (0.5mm instead of 1mm) to the same total thickness. Dry times increase with low temperatures and high humidity. The temperature must be above 50☏ for the entire 24 hours cure period after applying Spectrum. Hold the spray gun 4-8 inches from the surface and apply with a slow sweeping motion. A mask is not required for Spectrum sound deadening spray (water-based with minimal overspray), but it is recommended. Self-etching primer required for plastic and fiberglass. These surfaces will require scuffing and a primer (we recommend POR-15). Spectrum is designed to stick to metal but will adhere to most anything except glossy or high-wax surfaces. The maximum total effective thickness is 5mm. Apply 1mm at a time until you reach the desired thickness. 2mm is a little bit thicker than a quarter. 
1mm is about as thick as a credit card.Coverage Needed: 100% coverage of 1mm layers to a total thickness of 2-3mm.
