• Isikhathi sokuphumula: Amanye amaphrojekthi angase adinge isivalo esivala ngokushesha, ikakhulukazi ekwakhiweni noma ekulungisweni kwezimoto lapho isikhathi sibalulekile.
• Izidingo zokuvumelana nezimo: Ngokuya ngesicelo, njengokujoyina izinto okungenzeka zihlangabezane nokunyakaza (njengeukhunifuthiinsimbi), ungase udinge i-polyurethane sealant eguquguquka kakhulu.

Isiphetho

I-polyurethane sealantiyi-ejenti enamandla ehlanganisayo eyaziswa kakhulu ezimbonini kusukela kwezokwakha kuye kwezezimoto. Ukuguquguquka kwayo, ukumelana nesimo sezulu, nokunamathela okuqinile kuyenza ibe yisixazululo samaphrojekthi adinga izimpawu eziqinile, ezihlala isikhathi eside. Emhlabeni wezimoto,i-windshield polyurethane sealantibalulekile, hhayi kuphela ukunikeza ibhondi evikelekile yengilazi yemoto kodwa futhi ithuthukisa ukuphepha kwesakhiwo semoto.

Kungakhathaliseki ukuthi usebenza kumaphrojekthi amakhulu wokwakha noma ushintsha iwindshield yemoto, ukukhetha i-polyurethane sealant efanele kuqinisekisa umphumela onokwethenjelwa nohlala njalo ongamelana nezinselele zemvelo kanye nokuguga kwansuku zonke.
