Montimi i profileve të fasadës me pamje prekasti prej poliuretani realizohet lehtësisht me ngjitës strukturor dhe vida mekanike mbajtëse.

Hapi 1: Përgatitja e Fasadës dhe Veglat e Punës

Step 1: Substrate Preparation and Marking — Inspect the wall surface to confirm it is dry, clean, structurally sound, and free from loose paint or dust. Mark baseline reference lines using a chalk line and spirit level to align all profiles correctly. Duration: 1-2 hours per 15 m². Common Error: Mounting profiles onto damp, uncleaned, or crumbling masonry walls.
Step 2: Measuring and Miter Cutting (45 Degrees) — Measure the wall sections carefully and cut profile edges at exact 45-degree angles for corner joints using a high-speed miter saw equipped with a fine-toothed blade. Duration: 15-30 minutes per element. Common Error: Cutting at incorrect angles, creating wide joint gaps that are difficult to seal.
Step 3: Polyurethane Adhesive Application — Apply a continuous bead of polyurethane mounting adhesive along the back contact surfaces and cross-sectional joint faces of the profile. Duration: 5-10 minutes per profile. Common Error: Using standard silicone or acrylic caulk instead of structural polyurethane adhesive.
Step 4: Mechanical Fixation with Screws and Anchors — Press the profile firmly against the marked layout line. Drill countersunk holes through the profile into the wall and secure mechanical screws into masonry anchors. Mechanical fastening is mandatory. Duration: 10-15 minutes per element. Common Error: Relying exclusively on adhesive without installing mechanical screws.
Step 5: Joint Filling and Putty Application — Fill all screw head indentations and profile seams with exterior-grade joint putty using a flexible putty knife to achieve a continuous surface. Duration: 30-45 minutes per section. Common Error: Underfilling joint gaps, leading to visible seam lines after painting.
Step 6: Sanding the Joint Surface — Once the joint putty has fully cured, sand the treated areas smooth using granulim 180-220 sandpaper until the seams blend flush with the profile. Duration: 15-20 minutes per joint. Common Error: Using coarse sandpaper below 120 grit, which scratches the factory primer layer.
Step 7: Priming Touch-Ups and UV-Resistant Painting — While profiles arrive factory-primed, an optional coat of exterior primer can be applied to sanded areas. Apply at least two coats of high-grade UV-resistant exterior paint to protect the material from sunlight. Duration: 24 hours total curing time between coats. Common Error: Using interior paint or skipping UV-resistant exterior topcoats.

Hapi 2: Prerja e Këndeve 45°

Pritni profilet me gjatësi standarde 2400-2440 mm në kënd 45° me marzhin e llogaritur të mbetjeve 10%.

Hapi 3: Ngjitja dhe Ankorimi me Vida

Aplikoni ngjitësin ngjitës montimi me bazë PU në pjesën e pasme të profilit me densitet 150-220 kg/m³ (objektivi i prodhimit ~160 kg/m³) dhe vendoseni mbi vijën e lazerit. Fiksoni vidat mekanike me upa në mur për të siguruar mbajtje të përkryer. Koha e tharjes: rreth një orë.

Hapi 4: Stukimi dhe Lyerja me Bojë me Efekt Guri

Mbushni bashkimet dhe kokat e vidave me stuko elastike akrilike. Lëmoni me letër zmerile granulim 180-220 dhe aplikoni bojë fasade UV me efekt guri mbi astarin e fabrikës bojë bazë akrilike e bardhë njëkomponentëshe. Qëndrueshmëri në -100 °C / +80 °C.
