Vodič za Montažu Fasadnih Lajsni i Plafonskih Greda

Kompletan korak-po-korak vodič za pravilnu unutrašnju i spoljašnju montažu poliuretanskih lajsni i dekorativnih greda.

Pravilna montaža poliuretanskih fasadnih profila i plafonskih greda obezbeđuje savršeno ravne arhitektonske linije, potpunu vodonepropusnost spojeva i dugovečnost bez pukotina.

Potreban Alat i Materijal

Step 1: Inspect and Prepare the Substrate — Clean the mounting surface thoroughly using a stiff brush or vacuum to remove all dust, oil, and loose material. Ensure the substrate is completely dry and structurally sound before proceeding.
Step 2: Measure and Perform 45-Degree Miter Cuts — Measure the target area accurately. Cut the rigid polyurethane moldings or beams using a fine-toothed hand saw or a low-speed miter saw equipped with a fine carbide blade set precisely to a 45-degree angle for corner joints.
Step 3: Apply Polyurethane Assembly Adhesive — Apply a continuous bead of high-strength polyurethane (PU) assembly adhesive along the rear mounting channels of the profile and across the entire cut surface of all miter joints. Silicone adhesives must not be used.
Step 4: Position and Secure with Mechanical Fasteners — Press the polyurethane profile firmly onto the prepared substrate. Drive stainless steel screws through the profile into wall anchors at intervals of 40 to 50 cm to achieve mandatory mechanical fixing while the adhesive sets.
Step 5: Fill Joint Seams and Fastener Holes — Allow the PU adhesive to cure according to manufacturer instructions. Fill all countersunk screw heads and joint seams with an appropriate architectural joint filler or acrylic spackle.
Step 6: Sand the Surface Smooth — Once the filler has fully dried, sand all filled joints and screw locations flush with the profile surface using 180 to 220 grit sandpaper until smooth and uniform.
Step 7: Apply Optional Primer and Final Topcoats — Wipe away all sanding dust. Apply an optional additional coat of primer if required by your topcoat system, followed by two complete coats of premium paint (UV-resistant exterior paint is mandatory for outdoor installations).

Korak 1: Priprema Podloge i Lasersko Obeležavanje

Zid ili plafon se temeljno čisti od prašine i trošnih delova. Laserskom libelom se iscrtavaju tačne ose postavljanja. Vreme: 15-20 minuta po otvoru.

Korak 2: Precizno Sečenje pod Uglom od 45 Stepeni

Profili standardne dužine 2400-2440 mm seku se na uglovima pod 45° uz uračunavanje otpada 10%. Vrši se suva proba na zidu pre nanošenja lepka.

Korak 3: Nanošenje Lepka i Fiksiranje

Poliuretanski lepak montažno lepilo na bazi PU nanosi se u talasastim trakama na zadnju stranu profila. Element se čvrsto pritiska na podlogu. Vreme punog vezivanja iznosi oko jedan sat.

Korak 4: Zaptivanje Spojeva, Šmirglanje i Završno Farbanje

Spojevi se popunjavaju elastomernim kitom i šmirglaju sa granulacija 180-220. Nanosi se 100% akrilna boja preko belog fabričkog prajmera beli jednokomponentni akrilni prajmer.
