Processing
Substrates must be solid, clean, free of dust and grease. Moisten porous surfaces lightly with water to promote foam yield. Shake the 750ml canister vigorously 20x before use. Screw the canister hand-tight onto the gun. Invert the can and carefully dose the foam flow with the trigger. Shake regularly during processing. Fill cavities up to 65% because fresh foam still expands. For larger joints and cavities, moistening after each layer of foam is recommended. Remove spilled foam immediately with Bloem Spray Cleaner or Aceton. Opened canisters must be processed within 4 weeks. Before processing, please read the instructions on the label.
