Inkweto pu ibikoresho bikozwe mubikoresho byubukorikori byigana impu zimpu, imiterere yabyo irakomeye kandi iramba, nkuruhu rwa PVC, impapuro zo mubutaliyani, uruhu rwongeye gukoreshwa, nibindi, inzira yo gukora iragoye. Kubera ko imyenda y'ibanze ya PU ifite imbaraga zingana, irashobora gusiga irangi hasi, uhereye hanze ntishobora kubona ko hariho umwenda fatizo, uzwi kandi nk'uruhu rwatunganijwe neza, urangwa n'uburemere bworoshye, kwambara birwanya, kurwanya kunyerera, ubukonje na chimique irwanya ruswa, ariko byoroshye kurira, imbaraga zumukanishi no kurwanya amarira, ibara nyamukuru ni umukara cyangwa umukara, byoroshye.
Inkweto za PU zinkweto ninkweto zikoze mumyenda yo hejuru ikozwe muruhu rwibigize polyurethane. Ubwiza bwinkweto za PU nabwo ni bwiza cyangwa bubi, kandi inkweto nziza za PU zuruhu zihenze kuruta inkweto zimpu.
Uburyo bwo gufata neza: Gukaraba n'amazi yo kwisiga, wirinde gusukamo lisansi, ntushobora gukama neza, ushobora gukaraba gusa, kandi ubushyuhe bwo gukaraba ntibushobora kurenga dogere 40, ntibushobora guhura nizuba ryizuba, ntibishobora kuvugana numuti ukomoka kumubiri.
Itandukaniro riri hagati yinkweto zimpu za PU ninkweto zimpu zimpu: ibyiza byinkweto zimpu zimpu nuko igiciro gihenze, ibibi byoroshye gukomera, kandi igiciro cyinkweto za PU synthique zimpu zirenze iz'inkweto za PVC. Uhereye ku miterere yimiti, umwenda winkweto za PU synthique yimpu yegereye inkweto zimpu zimpu zuruhu ntikoresha plasitike kugirango ugere kubintu byoroshye, ntabwo rero azakomera, avunika, kandi afite ibyiza byamabara akungahaye, ubwoko butandukanye by'ibishushanyo, kandi igiciro gihenze kuruta inkweto z'impu z'uruhu, bityo gikundwa nabaguzi
