Auralex Foamtak Spray Adhesive
"Foamtak is quite simply the fastest and easiest way to mount Auralex acoustic foam products. Unlike Tubetak Pro adhesive, which is more permanent tougher to remove down the road, Foamtak can be applied lightly so that your foam is removable, or it can be applied heavily for a more permanent bond. Foamtak contains more actual solids than competing spray adhesives (youre getting more for your money!) and uses a unique spray pattern, so it offers greatly improved long-term bonding power vs. other sprays, which virtually ALWAYS dry out fail. Foamtak is guaranteed not to oxidize Auralex acoustic foams and may be purchased in any quantity needed. Youll love how easy Foamtak is to use! Mounts up to 96 sq. ft. or more per can depending on foam thickness. 1 per box."
