The Most Expensive Mistake in ETICS: Choosing the Wrong RDP RDP is the most expensive additive in an ETICS base coat. Compare EVA, EVA + silane, VA-VeoVa and hydrophobic RDP with real test data on EPS bond, impact and water absorption. EVA alone: 900-1000 g/m2 water. Hydrophobic RDP alone: fails impact. CHARING recommends RD 7015H + silane powder; dosages and mistakes included.
