4. Na plasta gypsum, bonding gypsum, caulking gypsum
Site na mmepe ngwa ngwa nke ụlọ ọrụ ihe owuwu, ọchịchọ ndị mmadụ maka ihe owuwu ụlọ ọhụrụ na-abawanye kwa ụbọchị. N'ihi mmụba nke ndị mmadụ na-amata na nchekwa gburugburu ebe obibi na ọganihu na-aga n'ihu nke ịrụ ọrụ nke ọma, ngwaahịa gypsum cimentity etolitela ngwa ngwa. Ka ọ dị ugbu a, ngwaahịa gypsum a na-ahụkarị bụ plasta gypsum, gypsum bonded, gypsum inlaid, na nrapado tile.
Plastering gypsum bụ ihe nkedo dị elu maka mgbidi dị n'ime na ụlọ elu. Mgbidi mgbidi a na-ete ya na ya dị mma ma dị mma, ọ dịghị agbada ntụ ntụ, na-ejikọta ya na isi ya, ọ dịghị ihe mgbawa ma daa, ma nwee ọrụ ọkụ; gypsum bonded bụ ụdị ọhụrụ nke ụlọ ọkụ ụlọ nrapado bụ ihe nnyapade nke gypsum dị ka isi ihe na-agbakwụnye ihe mgbakwunye dị iche iche. Ọ dabara maka njikọta n'etiti ihe mgbidi ụlọ inorganic dị iche iche.
