Preparation to installation
Take the plastic coating of the roof off.
Clean and degrese the surface.
First layer – Vibro-deadening
Install the vibration-damping material STP Aero as the first layer. It is a 2,3 mm thick mastic material for damping vibration on the external metal coating.
To install the first layer, you have to measure the size. You can use a ruler or a tape line. All the parts of the material must be rolled down.
Avoid air blisters formation, they will accumulate condensate. You can control the quality of rolling down if you look at the foil embossment. If the texture is almost unseen, you’ve rolled the material down properly.
Second layer – Sound absorption
Apply STP Biplast 10 mm as a second layer. Take the protective film off and mount the material on the first layer.
