Ukutshiza i-polyurethane ngokubanzi kunempembelelo encinci kulwakhiwo lwasebusika.Nangona kunjalo, xa iqondo lobushushu lisezantsi, ukunamathela kwesitshizi sepolyurethane esikumgangatho ophantsi kunye nomphezulu wodonga akubi kuhle, kukhangeleka ngathi ngumqhaphu wenqatha lobusi, kwaye kuya kuwa kamva.Namhlanje ukukunika ingqalelo kulwakhiwo lwasebusika lwe-polyurethane yokutshiza izinto zokugquma.

1. Ukwakhiwa kwe-PU yokutshiza kungcono ukuqala ngeqondo lokushisa: fumana indlela yokufudumala udonga, eyona nto imbi kakhulu yimfuno yezinto ezininzi zokufudumeza, okanye uzame ukwakha malunga nemini xa iqondo lokushisa liphezulu.

2. Gwema ukutshatyalaliswa kobushushu kwaye wenze umsebenzi omhle wokukhusela umoya ukuze ugweme ukuhla kwentsebenzo ngexesha lenkqubo yokukhupha amagwebu kunye nokunyanga.

3. Ukubonakala kwezinto eziphathekayo: nikela ingqalelo ekuphuculeni umsebenzi wokuphendula, ukuxuba xa uqwalasela inani le-ejenti ye-foam kunye nokulungelelaniswa kweqondo lokushisa eliphantsi.

4. Ubushushu bokwakha kufuneka bube ngaphezu kwe-5, ukwakhiwa kufuneka kugcine indawo yokwakha umoya, zama ukungasebenzi kwiimeko zokushisa eziphantsi.

5. Amacandelo angasetyenziswanga (ngokukodwa icandelo A), isiciko sombhobho kufuneka sigqunywe ngokuqinileyo ukukhusela ukufunxa umswakama kunye nokunyanga, izinto ezixubileyo kufuneka zisetyenziswe ngexesha elithile.

6. Njengoko izinga lokushisa liyancipha, izinga lokuchithwa kwe-mastic powder kwi-polymer mortar linganciphisa, kwaye ixesha lokuxuba kufuneka landiswe xa kulungiswa i-polymer mortar.Umlinganiselo wesamente kufuneka usetyenziswe ngaphakathi koluhlu oluchaziweyo, kwaye izinto eziphathekayo akufanele zixutywe, ngaphandle koko ixesha lokuqinisa liya kwandiswa.

Oku ngasentla kukuba uqalise ukutshiza i-polyurethane kwimimiselo yokwakha yasebusika, ebusweni bemozulu ebanda kakhulu, thina kunye ukuba sithobele ukwakhiwa kwemimiselo ukuze sifezekise iziphumo ezifunwayo.
