Montimi i Kurorave të Dritareve dhe Dyerve Hap pas Hapi

Udhëzues teknik profesional mbi montimin e sigurt dhe të saktë të kurorave arkitekturore me ngjitës strukturor poliuretani.

Montimi i kurorave arkitekturore të dritareve dhe dyerve prej poliuretani realizohet me lehtësi duke ndjekur vijën e qendërzimit dhe hapësirave simetrike.

Hapi 1: Qendërzimi dhe Veglat e Punës

1. Substrate Preparation and Inspection — Clean the mounting surface thoroughly to remove dust, oil, loose plaster, or moisture. The installation substrate must be entirely dry and structurally sound. Estimated Time: 15-20 minutes per section. Common Mistake: Applying adhesive over loose dust or damp masonry, which prevents proper chemical bonding.
2. Measurement and Miter Saw Cutting — Measure the target opening accurately and transfer dimensions to the polyurethane profile. Cut the ends using a miter saw set to a precise 45-degree angle for corner or return joints. Estimated Time: 10-15 minutes per profile. Common Mistake: Cutting without accounting for the profile depth, leading to misaligned miter joints.
3. Polyurethane Adhesive Application — Apply a continuous bead of polyurethane (PU) assembly adhesive along the rear contact surfaces and joint edges. Never use silicone. Estimated Time: 5-10 minutes per profile. Common Mistake: Using silicone sealant instead of dedicated polyurethane adhesive, causing bond failure.
4. Mounting and Mandatory Mechanical Fastening — Press the crown firmly against the surface. Drill pilot holes through designated recessed points and secure the piece with dowels and screws into the wall structure. Estimated Time: 10-15 minutes per anchor point. Common Mistake: Skipping mechanical screw anchoring and relying only on adhesive.
5. Joint Filling and Surface Sanding — Fill screw recesses and profile seam joints with technical joint putty. Once cured, sand the joints smooth using granulim 180-220 sandpaper until flush. Estimated Time: 20-30 minutes (plus curing time). Common Mistake: Using coarse sandpaper (below 180 grit), which scratches the polyurethane surface.
6. Coating and Final Painting — Apply an optional coat of primer over filled joints, followed by two topcoats of quality paint. Exterior installations require UV-resistant outdoor paint. Estimated Time: 1-2 hours (excluding drying time between coats). Common Mistake: Omitting UV-resistant paint on exterior facade installations.

Hapi 2: Verifikimi i Puthitjes me Kornizat Anësore

Vendoseni kurorën mbi kornizat vertikale me gjatësi standarde 2400-2440 mm dhe kontrolloni që skajet e kurorës të dalin simetrikisht 3–5 cm nga secila anë.

Hapi 3: Aplikimi i Ngjitësit dhe Montimi

Aplikoni ngjitësin ngjitës montimi me bazë PU në vijë të dyfishtë në pjesën e pasme të kurorës me densitet 150-220 kg/m³ (objektivi i prodhimit ~160 kg/m³) dhe shtypeni fort mbi mur. Për modele të mëdha përdoren vida të fshehura me upa. Koha e tharjes: rreth një orë.

Hapi 4: Stukimi dhe Lyerja UV

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