Come montare cornici per luce indiretta LED : Guida

Luce radente e atmosfere soffuse : Come installare cornici a gola per strip LED mantenendo la distanza ottimale dal soffitto senza aloni.

Il montaggio delle cornici per luce indiretta a LED in poliuretano si realizza incollando il profilo sulla sola parete per consentire il deflusso luminoso verso il soffitto.

Strumenti e Distanza Ottimale dal Soffitto (10–15 cm)

Surface Inspection and Reference Line Layout — Inspect the wall and ceiling surfaces for levelness and clean away dust or loose material. Measure down from the ceiling line to establish a clearance distance between 10 cm and 15 cm, then snap a continuous chalk line along the perimeter wall to guide lower profile placement. Estimated Duration: 30 minutes Common Mistake: Installing profiles over dusty or flaking paint surfaces without cleaning, leading to premature adhesive bond failure.
Measuring and 45-Degree Miter Cutting — Measure the wall perimeter accurately. Cut corner joints at a precise 45-degree miter angle using a fine-tooth miter saw. Dry-fit corner pieces against the wall to verify joint tightness before applying adhesive. Estimated Duration: 45 minutes Common Mistake: Using coarse saw blades that tear the high-density polyurethane edges, creating wide seams that require excessive filling.
Polyurethane Adhesive Application — Apply continuous beads of polyurethane (PU) mounting adhesive along the rear mounting flanges that contact the wall surface. Do not use standard silicone adhesives. Ensure even coverage along the entire length of the profile. Estimated Duration: 30 minutes Common Mistake: Using standard silicone sealant instead of dedicated polyurethane mounting adhesive, causing long-term adhesion failure.
Profile Mounting and Mechanical Screw Fixing — Press the profile firmly onto the marked reference line. Immediately drill countersunk pilot holes through the profile into the wall structure at 40 cm to 50 cm intervals. Secure the profile using wall anchors and screws until flush with the material surface. Estimated Duration: 60 minutes Common Mistake: Relying exclusively on adhesive and skipping mechanical screw fixings, which violates safety protocols for overhead moldings.
Joint Sealing and Sanding Preparation — Fill profile butt joints, corner miters, and countersunk screw heads with suitable joint compound or polyurethane joint filler. Allow the filler to cure completely according to manufacturer instructions, then sand smooth using grana 180-220 sandpaper. Estimated Duration: 45 minutes (excluding curing time) Common Mistake: Sanding with coarse sandpaper below 180 grit, which scratches the factory-primed polyurethane surface.
Priming and Final Paint Coating — Although profiles arrive factory-primed, applying an additional primer coat over sanded filled joints ensures uniform absorption. Finish with two coats of high-quality interior paint. For outdoor or high-UV exposed installations, UV-resistant exterior paint is mandatory. Estimated Duration: 90 minutes (excluding dry times) Common Mistake: Using standard non-UV resistant interior paints on exterior applications, leading to surface discoloration over time.

Fase 1 : Tagli d'Angolo a 45° (Tempo : 20 min)

Tagliate le aste da 2400-2440 mm calcolando lo sfrido 10% per preservare la continuità della gola interna.

Fase 2 : Incollaggio Strutturale sulla Sola Parete (Tempo : 25 min)

Stendete adesivo adesivo di montaggio a base PU (indurimento in circa un’ora) sulla superficie di contatto verticale in densità compatta 150-220 kg/m³ (obiettivo di produzione ~160 kg/m³).

Fase 3 : Alloggiamento Strip LED e Tinteggiatura (Tempo : 20 min)

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