Lits'ebetso tse tloaelehileng tsa HPMC:
Sekhomaretsi sa Lithaele
● Ho boloka metsi hantle: nako e telele ea ho bula e tla etsa hore lithaele li sebetse hantle.
● Ho ntlafala ho khomarela le ho hanyetsa ho thella: haholo-holo bakeng sa lithaele tse boima.
● Ho sebetsa ho molemo: lubricity le polasetiki ea plaster e tiisitsoe, seretse se ka sebelisoa habonolo le ka potlako.
Seretse sa samente / Seretse sa motsoako o omileng
● Motsoako o bonolo oa motsoako o omileng ka lebaka la ho qhibiliha ha metsi a batang: sebopeho sa maqeba se ka qojoa habonolo, se loketse lithaele tse boima.
● Ho boloka metsi hantle: ho thibela ho lahleheloa ke metsi ho li-substrates, metsi a loketseng a bolokiloe ka motsoako o tiisang nako e telele ea concreting.
● Keketseho ea tlhokahalo ea metsi: nako e eketsehileng ea ho bula, sebaka se atolositsoeng sa spry le tlhahiso e eketsehileng ea moruo.
● Ho hasana ha bonolo le ho ntlafatsa ho hanyetsa ho fokotseha ka lebaka la ho tsitsa ho ntlafetseng.
Sefate sa lebota
● Ho boloka metsi: ho eketsa metsi a mangata ka har'a seretse.
● Anti-sagging: ha u ala corrugation e teteaneng ea jase e ka qojoa.
● Kotulo e eketsehileng ea seretse: ho itšetlehile ka boima ba motsoako o omileng le motsoako o nepahetseng , HPMC e ka eketsa molumo oa seretse.
Tsamaiso ea Kantle ea Insulation le Finish System ( EIFS )
● Ho khomarela ho ntlafetse.
● Bokhoni bo botle ba ho kolobisa bakeng sa boto ea EPS le substrate.
● Ho fokotsa moea o kenang le ho kena ha metsi.
Boiketsi ba ho iteka
● Tšireletso khahlanong le ho tsoa ha metsi le ho chesoa ha lintho tse bonahalang.
● Ha ho na phello ho metsi a slurry a nang le viscosity e tlaase

Crack Filler
● Ho sebetsa ho molemo: botenya bo nepahetseng le polasetiki.
● Ho boloka metsi ho etsa bonnete ba hore mosebetsi o nka nako e telele.
● Ho hanyetsa ha Sag: bokhoni bo ntlafetseng ba ho kopanya seretse.
