Pane zvimwe "zvisingaoneki zvinhu" zvinoita kuti mdf kubva mumusungo unowedzera kutaridzika kupfuura zvigadzirwa zvehuni, nyanzvi yakawedzera. Shuwa inovandudzwa gore rimwe nerimwe, ine mvura yakawanda uye ine density diki, iyo inoita mdf pane yeMDF pane yakasarudzika-yakavakirwa zvinhu zvekutakura zvekufambisa uye kugadzirisa. Mukuita kwekugadzira mapani makuru haana kushandiswa formaldehyde.
Chikamu chezana ramakore rapfuura, kugadzirwa kweMDF kubva kuuswa pachinzvimbo chemuti wakaita kunge tarisiro yakanaka kwazvo, asi chigadzirwa hachina kuuya kuzoshandisa.
