PREPARATION AND APPLICATION
Use on dust-free and degreased surfaces. Cover devices and other surfaces to prevent them from getting dirty. Before applying, we recommend that you moisten dry substrates with water using a sprayer due to the better quality of the foam structure. Use the BK-Pur Premium Gun by screwing the can onto the NBS threaded gun. Shake the dose vigorously (at least 30 times). Fill large joints in several layers and moisten between each layer. The time required to pass between two coats of foam is 15-30 min. Dose sparingly, the volume of foam increases approximately two times after application times, however, the foam retains its shape upon final hardening. For cleaning guns and to remove foam residues use BK PU Cleaner, while the foam is still soft. Hardened foam can only be removed mechanically. For detailed instructions see product data sheet.
