Kungakhathaliseki ukuba uluhlu olunjani lokukhethwa kwamacwecwe anamhlanje, ukufunwa rhoqo kwabathengi basebenzisa i-plaster ngokusekelwe kwiimveliso zendalo. Umzekelo i-plaster plasters esekelwe kwisamente okanye ngomxube-lime umxube. Ukongezelela, i-plaster zamaminerali ezicwangcisayo zisebenzise ngempumelelo ukulungiswa kwangaphandle nakwintsimbi yezakhiwo nezakhiwo. Ukuhlaziywa kwendawo ephathwayo kuphunyezwe ngenxa yeemveliso ezahlukahlukeneyo ekubunjweni komxube we-mineral plaster, ecacisa igama kunye nefom leyo okanye uhlobo lwendawo.
Iindidi zokugcoba i-mineral plaster
Enye yeeplasta ezidumileyo zokunciphisa izityela - i-pebble. Igama laso libangelwa kubukho balo ngokubunjwa kwamacwecwe atyebileyo (okusanhlamvu). Xa isetyenziswe kumphezulu, isambatho ("ingubo") isakhiwo sogqirha senziwa. Ubungakanani bokusanhlamvu buxhomekeke kubukhulu be-inclusions - amacwecwe. Esi sibonakaliso (ubungakanani beqhekeza lesincinci) siboniswe ngokucacileyo kwipakethe yale nto yokugqiba. Ukupakishwa kwamaminerali okwakhiwa kwamatye kungasetyenziselwa imisebenzi yangaphakathi kunye neyekugqiba imisebenzi, inemilinganiselo ephezulu yokusebenza (ukutshatyalaliswa kwamanzi, ukunyuka kwemiphunga, ukuxhatshazwa kwiimpembelelo zangaphandle kunye nokutshintsha kweqondo lokushisa).
I- plaster yokubhenca i-mineral "bark beetle" ayifuni kakhulu kwaye inempawu ezifanayo zokusebenza. Ukwahluke kwaso kwinqatyambo yamacwecwe kukuba kwindawo yokuphathwa (ngokufaka umxube wamatye okanye i-marble chips), "isambatho soboya" sidalwa ngeendawo, njengokungathi zidliwa yi-beetle. Kufuneka kwakhona kuqaphele ukuba zonke iintlobo ze-plaster zokuthambisa izityela, kubandakanywa ne-facade, ukunikezela ngakumbi ukuhlobisa kalula ziboleke ekudwebeni.
