Montaža Prozorskih Poda i Odkapnika

Detaljan korak-po-korak vodič za pravilnu ugradnju fasadnih prozorskih poda (solbanaka) sa padom i zaštitnim odkapnikom protiv podlivanja vode.

Montaža fasadnih prozorskih poda od poliuretana zahteva formiranje blagog spoljašnjeg pada i precizno zaptivanje spoja sa prozorskim štokom kako bi se sprečilo prodiranje kišnice u zid.

Potreban Alat za Montažu

Step 1: Substrate Inspection and Surface Preparation — Clean the installation area thoroughly using a dry wire brush and dust blower to remove loose debris, mortar flashes, or grease. Ensure the mounting substrate is completely dry and structurally sound. Estimated Time: 15 minutes. Common Error: Applying adhesive over wet or dusty rendering, which causes bond failure.
Step 2: Measurement and 45-Degree Miter Cutting — Measure the window opening width precisely, adding required end-cap overhangs. Cut the polyurethane profile ends at a clean 45-degree miter angle using a fine-toothed miter saw. Estimated Time: 20 minutes. Common Error: Cutting at high blade speeds that melt the polyurethane edge rather than shearing it cleanly.
Step 3: Polyurethane Adhesive Application — Apply continuous 8 mm beads of polyurethane (PU) assembly adhesive along the back contact surface and joint faces. Do not use silicone sealants under any circumstances. Estimated Time: 10 minutes. Common Error: Using standard silicone or applying spot dabs instead of continuous adhesive beads.
Step 4: Profile Positioning and Mechanical Fastening — Press the sill profile firmly onto the substrate, verifying a forward drainage slope of at least 5 degrees with a spirit level. Drive stainless steel screws with wall plugs through countersunk holes spaced 40-50 cm apart. Estimated Time: 25 minutes. Common Error: Omitting mechanical screws and relying solely on adhesive.
Step 5: Joint Filling and granulacija 180-220 Sanding — Fill countersunk screw heads and 45-degree joint seams with flexible polyurethane putty. Allow the putty to cure completely, then sand flush using granulacija 180-220 sandpaper. Estimated Time: 30 minutes (excluding curing time). Common Error: Sanding before the joint putty has fully cured, causing indentation marks.
Step 6: Spot Priming and UV Topcoat Painting — Apply an acrylic primer over sanded joint areas if raw polyurethane is exposed. Finish the complete sill with two coats of high-grade UV-resistant exterior paint. Estimated Time: 40 minutes (plus dry times). Common Error: Using interior paint or skipping UV-resistant coatings on exterior surfaces.

Korak 1: Formiranje Nagiba Podloge (2–3°)

Betonski ili omalterisani parapet ispod prozora mora imati pad od najmanje 2 do 3% prema spolja radi slobodnog oticanja kišnice.

Korak 2: Sečenje Profila sa Bočnim Prepustima

Profili standardne dužine 2400-2440 mm seku se tako da prelaze bočne ivice prozorskog otvora za 3 do 5 cm sa svake strane uz otpad 10%.

Korak 3: Nanošenje Lepka i Postavljanje Pode

Lepak montažno lepilo na bazi PU se nanosi na donju stranu profila u neprekidnoj liniji i poda se čvrsto utisne ispod prozorskog štoka. Vreme sušenja iznosi oko jedan sat.

Korak 4: Zaptivanje Spoja sa Štokom i Bojenje

Spoj između poliuretanske pode i prozorskog okvira zaptiva se trajno elastičnim kitom i šmirgla sa granulacija 180-220. Nanosi se fasadna boja preko prajmera beli jednokomponentni akrilni prajmer.
