PREPARATION AND APPLICATION
The surface must be solid, clean, free of grease and oil. Moisten well. Cover non-foam surfaces. Before applying, we recommend moistening dry substrates with water. Shake the dose vigorously. Screw the can onto the NBS threaded gun. Fill large joints in several layers and moisten between each layer. The time it takes to pass between two coats of foam is 15-30 minutes. Dispense sparingly, the volume of foam after application increases approximately twice. For cleaning and removing debris foam use BK-PU Cleaner while the foam is still soft. The hardened foam can only be removed mechanically, after which the surface can be further treated with mortars or acrylic sealants. See the product data sheet for detailed instructions.
