Vodič za Farbanje i Pripremu Prajmera Profila
Detaljan korak-po-korak vodič za profesionalnu pripremu površine, šmirglanje i farbanje poliuretanskih profila u enterijeru i eksterijeru.
Fabrički prajmer na poliuretanskim profilima služi isključivo kao tehnička podloga za bolju adheziju i NE predstavlja završni zaštitni sloj, zbog čega je pravilna priprema i farbanje ključ dugovečnosti.
Potreban Alat i Materijal
- Substrate and Environmental Preparation — Verify that the wall or ceiling substrate is completely clean, structurally sound, and dry. Ensure room temperature is maintained within standard application limits before beginning installation.
- Precision Cutting and Adhesive Application — Execute 45-degree miter cuts on profile ends using a fine-toothed saw. Apply a continuous bead of dedicated polyurethane assembly adhesive along the joint edges and mounting surfaces. Standard silicone adhesives must not be used.
- Mechanical Fixing with Screws — Press the polyurethane element firmly into place against the substrate. Drive corrosion-resistant screws through the profile into the wall to provide mandatory mechanical anchoring while the polyurethane adhesive cures.
- Joint Filling and Surface Patching — Apply an appropriate architectural filler or joint putty over all screw heads, miters, and connection seams to create a smooth, continuous surface level with the profile face.
- Surface Sanding with granulacija 180-220 Paper — Allow the joint filler to cure completely. Lightly sand all patched areas and the factory-primed profile surface using granulacija 180-220 sandpaper to eliminate release agent residues and smooth out filler transitions. Wipe away all dust.
- Application of System Primer — Apply a uniform layer of system primer compatible with your chosen topcoat manufacturer over all filled joints and sanded surfaces to ensure homogeneous paint suction.
- Topcoat Painting — For indoor applications, apply 2 coats of quality interior paint. For outdoor applications, apply an elastic, UV-resistant exterior paint system designed for facade durability.
Korak 1: Matiranje Površine Šmirglom (180–220)
Površina profila se blago i ravnomerno prebriše finom šmirglom granulacija 180-220 kako bi se uklonili eventualni tragovi silikonskog odvajača iz kalupa i postigla savršena mikro-hrapavost za boju.
Korak 2: Gletovanje Spojeva i Homogeno Prajmerisanje
Nakon što je strukturni lepak montažno lepilo na bazi PU vezao (oko jedan sat), svi spojevi se popunjavaju kitom i šmirglaju. Preko kitovanih delova obavezno se nanosi prajmer kako bi površina imala jednaku moć upijanja.
Korak 3: Nanošenje Dva Završna Sloja Boje
U enterijeru se nanose dva sloja kvalitetne boje za zidove/plafone. Na spoljnim fasadama obavezno se koristi elastična 100% akrilna fasadna boja sa UV zaštitom preko belog prajmera beli jednokomponentni akrilni prajmer.
