It's the most important step in any application.

Put the vehicle in the car elevator.

Be sure to apply a high-pressure water wash. The water spurt must be as close as possible in order to guarantee the total removal of all dirt. A hand brush is helpful.

Keep in mind that a common low-pressure wash could not be enough, even in low mileage or new cars, because underbody dirt tends to have high adhesion.

Also, there are critical areas, as the wheel fenders internal edges that usually are not properly cleaned in a common cars wash.
Use a water-based degreaser, preferably a citrus based detergent.

Apply the degreaser by means of a sprayer, air pump or air gun. The Total Coat RA/88 gun used for the undercoating is also suitable.

Be sure the degreaser reaches all areas and let it work for at least 5 minutes.
Rinse with plenty of water and repeat if necessary. Blow the excess water off with an air gun.

Use a Citrikleen ™ Degreaser (or similar), diluted in 1:5 to 1:10 parts of water. Do not use it without diluting.

Apply the degreaser by means of an air gun. The very same gun used for the Sound Control Premium is also suitable.

Be sure the degreaser reach all areas and let it work for 5 minutes.

Wash with plenty of water. Repeat this step if necessary in any point.

Blow the excess water off by air blow.

Total Coat Sound Control Premium is a water based product, which means a clean, easy and safe handling, but under cold weather and/or high humidity conditions it requires some considerations for the curing process. For professional use you have these options:

Air drying only (under good weather conditions):
90 minutes at 72 F minimum. Do not apply under 72 F. Do not apply below 40% RH.
Coating must be kept away from water for 4 hours minimum.

IN COLD AND RAINY WEATHER CONDITIONS
Use an Space heater:
90 minutes at 113 F or
60 minutes at 130 F

Use of short wave Infra-red Lamps:
Allow 10 minutes of flash off at 30" lamp distance
Apply 30 minutes of heat at 30" lamp distance

Notes:
Always keep away the coating from water contact while drying. While the product looks dark gray it means it's still wet to the touch. Color will turn black, as the film external surface gets dry.

Look for all underbody areas that are "unprotected" and those that are already factory covered. Of course, be careful to apply the Sound Control Premium on both, but mostly on the uncovered areas. Apply the Sound Control Premium with the Total Coat RA-88 spray gun, in a uniform pattern on all desired areas, moving forward the spray slowly in one direction in a single hand.

The recommended application thickness is 0,5 to 1,2 millimeters. A visual guide for achieve this thickness is to observe the condition when the wet coating gets a textured "orange peel" look.

The air pressure recommended is between 20 to 40 psi. A higher pressure cause the spray drops to "rebound" and could also make small craters on the film applied, which is not advisable.

   Once finished the Sound Control Premium application, check the results (a good lantern is recommended):

Observe the film appearance. Watch for low thickness areas. A too thin coating won't show the "orange peel" look, and will be weak for sound dampening purposes.
Make any re-application you need at any moment (the film can be wet or dry).

Pass your fingertips above the vehicle external and painted areas close to the application. This way is very easy to find out to the touch if there has been some overspray contamination (not always visible). If you feel some small drops just wipe out with a wet cloth (water only) immediately.

The air gun is easily cleaned passing plenty of water through it until the water comes out clear. Never allow the product to dry inside the gun.
 

 1. Clean the surface with Citrikleen (or similar citrus-based product), diluted in 1:5 parts of water, using a wet cloth. Follow a wipe off with a wet cloth.
2. Be careful to remove all dirt, grease, oil, etc.
3. Mask the required areas, including moving parts and electrical items.
4. Screw the spray gun RA-88 in the Total Coat Sound Control Premium bottle.

5. Adjust the air pressure as needed (20 to 30 psi).
6. Apply the Sound Control Premium the same way indicated in the Outside Application Instructions.
7. Remove the masking before the coating dries.
8. Let the product dry before re-assembly any indoor element.
9. Small repairs or re-applications can be done by means of a hand brush.

 Some air pressure systems contaminate the out coming air with the compressor oil. Be sure the air you're using is free of oil mist, because even a minimum oil presence can affect the adherence of the Sound Control Premium . An alternative is to use an oil filter.

A wet cloth at hand is a must, in order to wipe out fast any undesirable splash.

Don't be confident in the underbody conditions you see. Frequently, old graphite coats and oil residues are not visible. That's the reason for a careful degreasing process.

Do not try to mix the Sound Control Premium with any other liquid or solvent, even with water.

In case you observe some dripping it will be due to two causes: Drops of water remaining from the wash process or a too thick application (3 millimeters or more).

If any drop of Sound Control Premium falls on your clothes, wet it immediately, as once dry it will be impossible to remove from the fabric.

Avoid applying Sound Control Premium on the exhaust system. If this happens, the product is resistant to 185º C, but some plastic odor would appear temporary.

The product bottles must be closed and kept in shade. Avoid heating.

If you did some masking during an application, remove the adhesive tape quickly when wet, before the film dries.

Thicker application (more than 2 millimeters) is not advisable, cause they won't perform better properties.

Small repairs can be achieved by means of a hand brush, moving it in short pulse perpendicular to the surface. This will produce a very similar texture than original.

1 bottle covers up to 1,5 m2 (16 ft2).
