Ma resins aya anozivikanwa nekuoma kwawo kwakanyanya, kuramba kupisa, uye kuramba kukwenya. Anoshandiswa zvakanyanya kugadzira zvigadzirwa zvakaita semidziyo yekicheni, midziyo yekudya kwemanheru, uye countertops dze laminate. Melamine yedu yemhando yepamusoro inoita kuti zvigadzirwa zvepurasitiki izvi zvisataridzike zvakanaka chete asiwo zvinotsungirira kuomarara kwekushandiswa kwezuva nezuva. Ingave resitorendi ine vanhu vakawanda kana imba ine vanhu vakawanda, zvinhu zvepurasitiki zvakagadzirwa ne melamine zvakagadzirwa nechigadzirwa chedu zvinogara kwenguva refu uye zvinogara kwenguva refu.

Nekushandisa melamine yedu, vagadziri vemachira vanogona kugadzira zvigadzirwa zvinodzivirira moto zvinowedzera kuchengetedzeka munzvimbo dzakasiyana-siyana, kubva kudzimba kusvika kuzvivakwa zvemabhizinesi.
Muindasitiri yemapepa, melamine inoita basa rakakosha. Inoshandiswa kugadzira mapepa anoshanda zvakanaka, akadai seaya anoshandiswa mukudhindwa nekuiswa mumidziyo yemhando yepamusoro. Mapepa akagadzirwa neMelamine ane simba rakawedzerwa, haapindi mvura, uye anopenya. Izvi zvinoita kuti akwanise kugadzira zvinhu zvekurongedza zvinobata maziso zvinogona kuchengetedza zvigadzirwa panguva yekufambisa nekuchengetedza ukuwo zvichiita kuti vatengi vaonekwe zvakanaka.
Muindasitiri yezvinonamira nependi, melamine yedu chinhu chakakosha. Inoshandiswa mukugadzira zvinonamira kuti zvivandudze simba rekubatana uye kugara kwenguva refu. Muzvinonamira, melamine inobatsira kuwedzera kuomarara uye kuramba kwemakemikari pamusoro pakafukidzwa. Ingave iri kunamira fenicha pamwe chete kana kudzivirira simbi kubva mukuora, zvinonamira nependi zvakagadzirwa ne melamine zvakagadzirwa nechigadzirwa chedu zvinopa kushanda kwakavimbika.
