Summary
Exterior expanded polystyrene (EPS) render mouldings easily crack or detach when installed hollow without solid backing. Proper repair requires removing damaged sections, fixing a rigid cement sheet backing across the void, and securing custom-cut replacement EPS mouldings using heavy-duty exterior construction adhesive applied in a continuous serpentine pattern. Landlords performing DIY repairs can save significantly on contractor fees while ensuring long-term weatherproofing by sealing top and bottom joins thoroughly with waterproof silicone.
Key Points
Why it matters: Understanding structural backing requirements for exterior architectural mouldings prevents water penetration and avoids costly repeat contractor repairs.
