Foam adhesive comprises (in wt.%) polyol (10-35), plasticizer (0.1-25), catalyst (0.1-10), isocyanate (25-60), and propellant (5-30). An independent claim is also included for using foam adhesive for adhesive bonding of building blocks and other building materials, comprising spraying or immersing the surfaces of the building blocks or building material to be bonded with an accelerating agent, applying at least one line-shaped foam body continuously or discontinuously on the surfaces to be bonded with foam adhesive, and an adhesive layer of 1-5 mm is formed after the disintegration of the foam in a period of 4-10 seconds and the surfaces to be bonded are placed together on the building material. |
