Vuto likhoza kukhala lolowera kwambiri m'malo mwa chikasu chamankhwala. Utoto ukhoza kusintha momwe kuwala kumayendera kudzera mwa nsangalabwi ya porous, kupanga mawonekedwe onyowa kapena oderapo pozungulira malo omwe adakonzedwa. Kwa nsangalabwi yofewa yoyera, gwiritsani ntchito makina opangidwa kuti azitha kulowa mkati mokhazikika komanso osadetsa.

5. Kodi fakitale iyenera kuyesa bwanji epoxy isanagwiritse ntchito pamwala woyera?

Yesani ma epoxy pama slabs oyimira oyimira pa kutentha kwenikweni kwa fakitale. Lembani chiŵerengero chosakanikirana ndi kuchuluka kwa ntchito, fufuzani malire olowera, kulola kuchiritsidwa kwathunthu, pukuta slab pogwiritsa ntchito njira yachibadwa, ndi kuyerekezera mtundu, kuwala, kamvekedwe kachikasu, mthunzi, mawonekedwe a kukonza, ndi gloss. Pama projekiti apamwamba, onjezani kutentha kofananira kapena kuyezetsa ukalamba wa UV musanavomereze zambiri.
