Vodič korak po korak za skrivenu LED rasvetu: Kako izmeriti visinu od plafona, zalepiti lajsne i sprečiti probijanje svetla.
Stručna montaža lajsni za skriveno LED svetlo od poliuretana zahteva precizno poravnanje visine kako bi se dobio savršeno mek i ravnomeran snop indirektne svetlosti.
Potreban alat i priprema
- 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 granulacija 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.
Korak 1: Lasersko obeležavanje visine (Trajanje: 15 min.)
Postavite laser na 10 do 15 cm ispod plafona i označite liniju montaže. Masivna gustina od 150-220 kg/m³ (proizvodni cilj ~160 kg/m³) omogućava savršeno pravu liniju bez ugibanja.
Korak 2: Sečenje uglova pod 45 stepeni (Trajanje: 25 min.)
Profile dužine 2400-2440 mm isecite pod uglom od 45 stepeni u gering kutiji uz uračunat dodatak za rezove od 10%.
Korak 3: Nanošenje lepka i montaža na zid (Trajanje: 30 min.)
Nanesite PU lepak montažno lepilo na bazi PU po donjoj kontaktnoj površini profila. Spojeve dve lajsne zavarite specijalnim lepkom za spojeve do punog stezanja (oko jedan sat).
Korak 4: Alu-profil, šmirglanje i farbanje (Trajanje: 25 min.)
Zalepite alu-šinu u žleb za hlađenje LED trake do -100 °C / +80 °C. Nakon obrade sa granulacija 180-220, fabrički prajmer beli jednokomponentni akrilni prajmer se boji zidnom bojom. 100% otporno na vlagu ispod 1%. Ponuda važi 7 dana, isporuka franko fabrika.
