1 SHEET = 20" X 13" X 4MM THICK

As well as being a self-adhesive to ensure it sticks to the surface you are applying it on, PROMAT is malleable to work into indentations and around curves in panels.

 The product is non‐ toxic, waterproof, and does not decompose under harsh weather conditions due to anti‐corrosion and sealing properties. It is also well-suited for basic improvement in the acoustics of the car when fitting and using car audio, as well as refitting and upgrading sound insulation.

 The sheets can be installed in a wide spectrum of temperatures without the need for hearing, although, for maximum operating comfort, it is recommended to be achieved at ambient temperatures above +10oC.

For best results, the surface must be dry, clean and well degreased and using a PRO roller is suggested to adhere tightly to the entire surface of the mat, to avoid the formation of air gaps.
