Lapho i-asphalt ye-asphalt ye-asphalt ephelele isebenzisa i-blowtorch engaguquki ukushisa ishubhu yomlilo yethangi le-asphalt, i-chimney ethangini le-asphalt kufanele ivulwe kuqala, futhi i-blowtorch ingakhishwa kuphela ngemuva kokuthi i-asphalt ye-asphalt ye-liquid. Lapho ilangabi lokushisa i-blowtorch likhulu kakhulu noma lisakazeka, isilinganiso se-blowtorch kufanele siguqulwe kuqala, futhi uphethiloli owedlulele kufanele ushiswe ngaphambi kokusebenzisa.

Ngaphambi kokusebenzisa i-blowtorch ye-asphalt ye-asphalt esebenza ngokugcwele, ipayipi le-oyela le-oyili kanye netheku eliseduzane lezinto ezibonakalayo kufanele livalwe kuqala. Ngemuva kokuthi i-blowtorch ephathekayo ibilisiwe, akufanele ibe seduze kwezinto ezivuthayo. Isaphulelo se-asphalt esizenzakalelayo kufanele sibe ngesivinini esiphakathi lapho silayishwe ngokuphelele nge-asphalt. Uma kukhona ijika noma ukwehla, kufanele kwehliswe phansi ngaphambi kwesikhathi, futhi ukubopha okuphuthumayo kufanele kugwenywe ngangokunokwenzeka. Uhlelo lokushisa aluvunyelwe ngesikhathi sokushayela.
