Come montare mensole sotto balconi e bow-window : Guida

Eleganza classica per gli aggetti di facciata : Come allineare e fissare mensole decorative sotto solette e balconi garantendo armonia e sicurezza.

Il montaggio di mensole e beccatelli decorativi sotto balconi e bow-window valorizza gli aggetti di facciata con ritmo e proporzioni monumentali.

Avvertenza Statica : Mensole Non Portanti

Measure Facade Overhang and Calculate Spacing — Measure the total linear length of the balcony or bay window underside. Mark the outer corner positions first, then divide the remaining center span into equal increments between 60 cm and 80 cm to determine exact corbel centerlines.
Prepare Substrate and Miter Profiles — Clean the wall substrate to eliminate dust, oil, and loose material. If the corbel profiles meet at facade corners, perform exact 45-degree miter cuts on a fine-tooth saw dedicated to rigid polyurethane.
Apply Polyurethane Assembly Adhesive — Extrude continuous beads of heavy-duty polyurethane (PU) assembly adhesive onto all back and top contact surfaces of the corbel. Do not use silicone, as it lacks structural shear performance.
Mount Profile and Drive Mechanical Fasteners — Press the corbel firmly against the marked layout line on the wall substrate. Immediately drive stainless steel screws through pre-drilled countersunk holes into masonry wall anchors to secure the profile mechanically.
Fill Screw Recesses and Substrate Joints — Apply exterior-grade polyurethane putty over all countersunk screw heads and perimeter joint seams where the corbel meets the wall and ceiling surfaces.
Sand Joints and Evaluate Surface Primer — Allow the putty to cure, then sand all patched surfaces smooth using 180 to 220 grit sandpaper. Inspect the factory primer coat and apply an additional acrylic exterior primer if required by local coating standards.
Apply Final UV-Resistant Exterior Paint — Coat the entire installed corbel assembly with two coats of premium UV-resistant exterior paint to protect the polyurethane material from solar radiation and weather exposure.

Fase 1 : Calcolo Interassi e Tracciamento Simmetrico (Tempo : 15 min)

Tracciate gli assi di simmetria ogni 50–80 cm sotto l'aggetto calcolando la tenuta termica a -100 °C / +80 °C.

Fase 2 : Incollaggio PUR e Fissaggio Meccanico Inox (Tempo : 25 min)

Stendete adesivo adesivo di montaggio a base PU (indurimento in circa un’ora) sul retro in densità compatta 150-220 kg/m³ (obiettivo di produzione ~160 kg/m³) e avvitate i tasselli inox nella soletta.

Fase 3 : Sigillatura dei Bordi e Pittura Silossanica (Tempo : 20 min)

Levigate i raccordi con carta grana 180-220 e applicate pittura per esterni su primer primer acrilico bianco monocomponente. idrorepellente (inferiore all’1%). Offerte 7 giorni, consegna franco fabbrica.
