ʻO ka hoʻopili maikaʻi ʻole o ka uhi ʻana i ka ʻili o ka substrate non-absorbent
ʻO ka substrate kahi mea hoʻoheheʻe ʻole a porous paha (e like me ka PVC a i ʻole ke kiʻi ʻoniʻoni PET), a ʻo ka hoʻopili ʻana o ka varnish coating i ka ʻili o ka substrate e ʻilihune paha. Pane: E hoʻomākaukau i kahi lipine scotch a me kahi mea hana mesh, e kaha i kahi laina keʻa ma ka uhi, a laila e hoʻopaʻa iā ia. ʻO ka nui o ka lipine uhi i haehae ʻia e ka lipine e hōʻike ana i ke kiʻekiʻe o ka hoʻōla a me ka pili ʻana o ka uhi. Inā ʻaʻole i haehae ʻia ka uhi ʻana, maikaʻi ka adhesion. Inā haehae ʻia ka uhi ʻana ma kahi ākea, ʻaʻole kūpono kēia varnish no ka hoʻohana ʻana i nā substrates non-porous a pono e hoʻololi ʻia.
