GT Liqui-Damp X air dries to the touch within 8 hours and fully sets in 8-24 hours depending on application. GT Liqui-Damp X Sound Deadener covers and adheres to almost any surface. Whether on painted or rough(sanded) surfaces, grease-free metallic panels provide the most adhesive applications. A finished, cured surface is sandable and paintable and is resistant to abrasion or chemicals. This version dries to a light gray or tan color and is odorless when cured. GT Liqui-Damp X Sound Deadener weighs 3 lbs per Quart. Two or more thin coats will provide the best looking and performing finish. Thicker coats will take longer to dry and are prone to clumping and cracking. GT Liqui-Damp X Sound Deadener is designed to be used alone or in combination with our GTMAT sheet product. Use GTMAT first to cover large holes, then apply GT Liqui-Damp X over the GTMAT. Please see our informative video for an example of this application. Applying GTMAT over GT Liqui-Damp X is not recommended unless the liquid layer has been painted.
