FREQUENTLY ASKED QUESTIONS

Q&A TECHNICAL HUB
Coverage depends on the application method and substrate roughness. For bead-and-spot bonding of insulation boards, consumption is approximately 3.0–4.0 kg/m². For full-surface bonding, it is approximately 4.0–6.0 kg/m². For reinforced levelling coats (4 mm thickness in 2 coats), consumption is approximately 1.3–1.5 kg/m² per mm of thickness.
