Levkas - kuyini? Indlela yokwenza izandla ze-levkas?

Abantu abaningi lapho belungisa indlu bahlangabezana nomqondo onjengokuthi gesso. Kuyini, akubona wonke umuntu owaziyo. Ngenxa yalokhu, futhi kungaba nobunzima lapho uhlobisa izindonga ngezandla zakho.

Izindonga zase Lefkas - ukuqedela izinga eliphezulu kakhulu ngokusebenzisa izinto ezikhethekile. Ngokuvamile, isisombululo se-chalky noma se-plaster sisetshenziselwa lokhu. Le ndlela yokuqeda kufanelekile ukulungiselela izindonga zokudweba.

Ubuchwepheshe bokusebenzisa i-levkas

Ukubetha izindonga usebenzisa le nqubo kungenziwa ngokuzimela. Wonke umsebenzi wenziwa ngezigaba eziningana:

1. Isiteji sokulungiselela sihilela ukuhlanza ubuso bezindonga kusukela endwangu endala. Ukuhlanza kumele kube okujulile, ngakho-ke ngisho noqweqwe lwamapulangwe kumele luhlanjululwe.
2. Hlola ngokuphelele izindonga. Yonke imifantu kanye nezimbobo ezikhona (kodwa ezijulile kuphela) zidinga ukugcwaliswa nge-putty. Kulesi sigaba kubalulekile ukusebenzisa isakhiwo ngesisekelo samasenti. Ungathatha futhi i-alabaster (ingxube eyomile esekelwe ku-gypsum), ikakhulukazi uma i-levkas ihlelwe esikhathini esizayo. Kuyini, kuchazwe ekuqaleni kwalesi sihloko.
3. Izindawo lapho ukuqhuma okukhulu kakhulu okwakubhekwa khona, ngaphezu kwe-plaster yamakhemikhali, kufanele kube yi-glazed nge-glass grinder. Futhi, ngenhloso yalokhu, isikhala singasetshenziswa.
4. Ngemuva kokuthi zonke iziphambeko ezinkulu zingase zisuswe, kungenzeka ukuthi uqhube umklomelo. Lesi sigaba asikwazi ukuphuthelwa kunoma yikuphi. Iqiniso liwukuthi i-primer yenza umsebenzi obaluleke kakhulu. Ngenxa yalokho, kungenzeka ukufezekisa ukubopha okuphezulu kokusebenza kokuqedela emkhathini, futhi lokhu kuncipha amathuba okuba i-putty izowa.
5. Ngemuva kokuqala, sebenzisa ungqimba lwezinga lokubeka. Ubukhulu bayo kufanele bube yi-2 mm kuphela. Lokhu kuqina kufanele kube ngokwanele ukuze uthole indawo ephelele ngokugcwele. Uma lokhu kungakutholakali, kanti enye ingqimba ingasetshenziswa, noma kunjalo, isendlalelo ngasinye esilandelayo sokugcwalisa singasetshenziswa kuphela uma isendlalelo sangaphambilini somile ngokuphelele.
6. Isendlalelo se-primer.
7. Kuphela manje kungenzeka ukuthi usebenzise i-gesso yezindonga ngezandla zakhe, bese usebenzisa isakhiwo esivela echokheni noma ekhayeni. Ukunakekelwa kufanele kuthathwe ukuqinisekisa ukusebenza okufanayo kwento.

Ngemuva kokuthi i-gesso (okuyiyo, echazwe ngenhla) isomile ngokuphelele, ungaqala ukudweba noma udonga.

Ukwamukelwa kwezithombe eziphathekayo

I-Levkas (iyini, echazwe kulesi sihloko) iphinde isetshenziswe uma izindonga seziqedile ngemidwebo ekhethekile ephathekayo. Kulokhu, ubuchwepheshe buhlukile kakhulu:

1. Yonke indawo kufanele ihlukaniswe ngezikwele ezihlangene no-30 noma 40 cm.
2. Ngesikwele ngasinye, sebenzisa iphethini yephethini ekhethiwe, eyisiyingi.
3. Faka isixazululo se-plaster emigqeni esetshenzisiwe, futhi kufanele uthathe ukunakekelwa ukuqinisekisa ukuthi isakhiwo sephethini sinesakhiwo esifanayo esigcawini ngasinye.
4. Shiya izinsuku ezimbili ukuze usomile.
5. Susa konke ukungalungi (ngeshwa, ngeke kugwenywe) usebenzisa isikhumba esikhethekile.

Manje udonga ngephethini lingadwetshwa. Endabeni ka-gesso, kungcono ukunikeza okuphambili kumdwebo we-acrylic-based based.

Ukwakhiwa kwe-levkas

Kunezinhlobonhlobo ezimbili ze-gesso: usebenzisa ukhiye noma i-lime. Njengoba zingekho ngaphansi komunye nomunye, nokho, kukhona ukungafani ekulungiseleleni isixazululo.

Ungalungisa i-gesso ngezandla zakho. Ingxube esekelwe kukiki:

• 5 amalitha amanzi;
• 3 kg we-chaki ehlungiwe;
• 30 g weglue.

Amanzi kufanele athiswe ekushiseni kwama-40-50 degrees. Ngemuva kwalokho, isikhokhelo esifakiwe sifike esitsheni, senziwe ngokuqedwa kwayo, futhi manje kungenzeka ukuletha iglue ingxube. Ukunakekelwa kufanele kuthathwe ukuqinisekisa ukuthi ukwakheka kuhambisana, ngaphandle kwezimbungu.

I-Calcareous levkas

Ukuze uthole i-levkas yokubala kubalulekile ukulungiselela:

• 2-3 kg we-soda hydrated;
• 0.5 kg wedayi;
• 50-80 g wefulawa usawoti;
• 150-200 g we- alum-alkali alum ;
• Amanzi.

Ukungafani kokubunjwa ukuthi kudingeke ukuthi kusetshenziswe kuphela endaweni ehlanjululwe yodonga.

Putty for gesso

Kukhona izingxube ezikhethekile ezenziwe ngomumo ezisuselwa ku-gypsum, isibonelo "Knauf", "Weber Vetonit", "ama-Klims", "Ivsil". Ziyasetshenziswa uma kuhlelwe ukuthola amaphethini wokuvota. Ukuzilungiselela ngeke kuthathe isikhathi esiningi, ngoba i-powder eyomile ihlanjululwa ngokwanele ngamanzi kuya esimweni se-viscosity.

Emva kokulungiselela noma iyiphi ingxube, kubalulekile ukuhlola izinga le-viscosity, ngoba le parameter ingathinta izinga lomphumela wokugcina. Ukuze wenze lokhu, inani elincane lempahla kufanele lisetshenziswe ku-spatula encane, eyabe isetshenziswe ngokuqondile. Kulesi sikhundla, ingxube kufanele igwebe kancane kancane, ekhombisa ukuthi i-putty ilungile. Uma kuvela amanzi amaningi, khona-ke udinga ukwengeza ingxenye encane ye-powder, uma unamanzi amaningi kakhulu. Gcina ithrekhi yezinga le-viscosity njalo uma uxuba.

Amathuluzi we-levkas

Ngaphambi kokwenza i-gesso, udinga ukulungiselela namathuluzi akhethekile:

1. Isibhamu se-pneumatic spray, noma isibhamu se-spray, sokuqedela udonga noma u-lime udonga. Kungenzeka ukusebenzisa i-analog yomhlahlandlela, kodwa-ke, kufanelekile ukucabangela indawo yokuphathwa kwezindonga. Uma usebenzisa i-sprayer ye-pneumatic, kufanele futhi unakekele imishini yokuzivikela, ikakhulukazi, iphathelene neglavu yegraber, izibuko kanye nomoya wokuphefumula.
2. Brush-maklovitsa. Ukushintshwa okungabizi kwesibhamu se-spray. Into esemqoka ekusebenziseni leli thuluzi yisiqondiso sokusebenzisa ingxube ye-gesso. Kudingekile ukuthi usebenzise izendlalelo eziningana, okugcina kokubili kube ngumbono komunye nomunye, futhi okulandelayo - kuqondiswe efasiteleni. Lolu hlelo lokusebenza luzogwema ukubukeka kwehlukaniso kusukela ebhujameni.
3. I-spatula ebanzi yokusebenzisa i-viscous gypsum putty. Ngokwenza kanjalo, kufanele ulandele imithetho ethile. Inani lezinto ezibekwe phezu kwe-spatula akufanele zibe mkhulu kakhulu noma ezincane kakhulu. Ungasebenzisa ingxube kunoma iyiphi indawo elula, kodwa, njengombandela, yenze kangcono kusuka ekhoneni. Ukunyakaza kufanele kube yi-arc, ne-ungqimba yenhlanganisela encane. Isendlalelo ngasinye esiseduze kumele siguquke ngenye yangaphambilini.

Futhi, udinga ukulungisa umshini wokubhola nge-buzz ekhethekile kalula futhi ngaphandle komzamo omkhulu wokulungisa ukubunjwa kokuvumelana okufisayo.

I-Lefkas iyindlela yokuhlobisa, engenziwanga nje kuphela ezindongeni, kodwa futhi nasendlini, ezokwenza kube lula ukuhlobisa igumbi ngesitayela esisodwa.
