Hana Nui
➢ Hiki i ka SNF-A ke hāʻawi i ka mortar wikiwiki plasticizing wikiwiki, kiʻekiʻe liquifying hopena, haʻahaʻa entraining hopena.
➢ He kūpono maikaʻi ʻo SNF-A me nā ʻano mea hoʻopaʻa sima a i ʻole gypsum, nā mea hoʻohui ʻē aʻe e like me ka de-foaming agent, thickener, retarder, expansive agent, accelerator etc.
➢ He kūpono ʻo SNF-A no ka tile grout, nā pūhui hoʻopaʻapaʻa ponoʻī, ka ʻiʻo maka kūpono a me ka paʻakikī o ka papahele kala.
Hana Huahana
➢ Hiki ke hoʻohana ʻia ka SNF ma ke ʻano he mea hoʻomaʻemaʻe no ka hamo maloʻo maloʻo no ka loaʻa ʻana o ka hana maikaʻi.
☑ Ka waiho ʻana a me ka lawe ʻana
Pono e mālama ʻia a hāʻawi ʻia ma lalo o nā kūlana maloʻo a maʻemaʻe i kona ʻano pūʻolo kumu a ma kahi o ka wela.
☑ Ola ola
ʻO ke ola o ka mālama ʻana he 10 mahina. E hoʻohana iā ia i ka hiki wawe ma lalo o ke kiʻekiʻe o ka mahana a me ka haʻahaʻa, i ʻole e hoʻonui i ka nui o ka caking.
☑ Palekana huahana
ʻAʻole pili ka Naphthalene superplasticizer SNF-A i nā mea pōʻino. Hāʻawi ʻia ka ʻike hou aku e pili ana i nā ʻano palekana ma ka Pepa ʻIkepili Palekana.
