Amino resin
Mushonga weAmino resin wekusvina ganda ndiwo "nyanzvi yekugadzira" mukuita kwekuchenesa ganda. Nekuzadza kwakanaka kwekusarudza, unoshanda zvakanaka panzvimbo dzakapfava dzakadai semipendero nemipendero yeganda, zvichideredza kusiyana kwezvikamu uye kugadzirisa dambudziko renzvimbo yakasununguka. Panguva imwe chete, unopa ganda kunzwa kwakasiyana kwekuzara, kusimba uye kutwasuka. Kana mushonga weacrylic wekusvina ganda une basa re "kuzadza nekunyorovesa", mushonga wekugadzira ganda une basa re "kugadzirisa zvakakwana", saka hunyanzvi hwemushonga weamino resin wekusvina ganda ndehwekuti "kuumba kwakasimba uye kuzadza kwakasarudzwa".
