Montaža Fasadnih Obloga: Vodič Korak po Korak

Detaljan korak-po-korak vodič za postavljanje poliuretanskih fasadnih profila, venaca i šovni na spoljašnjim zidovima zgrada.

Montaža fasadnih poliuretanskih elemenata zahteva upotrebu otpornog spoljašnjeg lepka i pravilnu obradu elastičnih spojeva kako bi se obezbedila trajna zaštita od klimatskih uticaja.

Potreban Alat za Fasadnu Montažu

Step 1: Wall Preparation and Marking — Inspect the wall substrate to confirm it is fully dry, level, and free of contaminants. Measure the facade alignment using a laser level, marking precise target lines for every cladding section. Estimated time: 30–45 minutes per elevation. Common mistake: Mounting over damp or crumbling plaster, which leads to total bond failure.
Step 2: Profile Measurement and 45-Degree Miter Cutting — Measure profile lengths accurately, accounting for corner intersections. Cut profile edges at a precise 45-degree miter angle using a fine-tooth miter saw to ensure tight, seamless corner joints. Estimated time: 10 minutes per profile. Common mistake: Cutting with coarse hand saws, which creates jagged polyurethane edges that hinder flush seam alignment.
Step 3: Polyurethane Adhesive Application — Apply continuous beads of polyurethane-based assembly adhesive along the rear mounting channels and joint connections of the profile. Never use silicone adhesive under any circumstance. Estimated time: 5 minutes per profile. Common mistake: Applying spot-dots of adhesive instead of continuous beads, allowing water infiltration behind the cladding.
Step 4: Mechanical Fixing with Screws and Dowels — Press the profile firmly against the substrate and drill anchor holes through the designated recessed grooves. Secure the element mechanically using corrosion-resistant screws and masonry dowels spaced every 40-50 cm. Estimated time: 15 minutes per section. Common mistake: Relying solely on adhesive and omitting mandatory mechanical dowels.
Step 5: Joint Filling and Sanding — Fill all screw recesses and profile joints with exterior-grade joint putty. Allow full curing according to manufacturer guidelines, then sand the seams perfectly flush using granulacija 180-220 sandpaper. Estimated time: 30 minutes active labour (plus drying time). Common mistake: Using coarse sandpaper under 150 grit, which scratches the factory-primed profile surface.
Step 6: Primer Verification and Final UV Coating — Ensure all sanded joints are dust-free. Apply an optional exterior primer coat if recommended by the paint manufacturer, followed by 2 complete coats of UV-resistant exterior paint. Estimated time: 1-2 hours (plus drying intervals). Common mistake: Using interior-grade or non-UV paint, causing rapid discoloration and surface chalking under direct sunlight.

Korak 1: Priprema Fasadne Ravni

Fasadni armirani lepak mora biti potpuno suv i otprašen. Laserskom libelom iscrtavaju se precizne horizontalne i vertikalne vođice.

Korak 2: Sečenje i Nanošenje Konstrukcijskog Lepka

Profili standardne dužine 2400-2440 mm seku se u vođici uz otpad 10%. Lepak montažno lepilo na bazi PU se nanosi na poleđinu u talasastoj liniji i profil se čvrsto pritisne uz zid. Vreme sušenja iznosi oko jedan sat.

Korak 3: Mehaničko Osiguranje i Kitovanje

Za profile širine preko 16 cm preporučuje se dodatno fiksiranje skrivenim fasadnim tiplovima. Spojevi se popunjavaju elastičnim kitom i šmirglaju sa granulacija 180-220.

Korak 4: Završno Bojenje sa UV Zaštitom

Preko belog fabričkog prajmera beli jednokomponentni akrilni prajmer i obrađenih spojeva nanosi se kvalitetna 100% akrilna ili silikonska fasadna boja u dva sloja.
